[Help] Mikrotik CAPsMAN Wireless download speed max 200Mb, but PC's /Mobile's link speed is 866Mbps

Wed Sep 02, 2020 6:32 am

My devices:
Router is CCR1009-7G-1C-1S+ (tile), 5 APs are RBwAPG-5HacT2HnD.

My network toplogy:

Even PCs or Mobiles link speed is 866Mbps, but actually speed only 200Mb,


below is mobile to LAN server:

hello,

why do you have so many configs in capsman? one for 2,4 and 5 ghz each should be enough? (auto channel)
Regarding speeds in capsman: you should enable local forwarding, otherwise all traffic gets routed to the capsman-controller, wich can be a bottleneck.
This way the load will be distributed accross all your caps.

Note that with local forwarding you will need to create local bridges on all of your caps.

note also that wap ac is not the fastest, max net-throughput with local bridge in my experience is around 300 mbit/s (wich is not bad for a device in this price-point)

thank you.
I have tried use Local Bridge but the same result, max dowload 200Mb.

about channels, firsttime I try use manual channels and now use auto channels: only channel2.4 and channel5 is using.

In real life (no matter what hardware you use) you will generally get up to 1/2 the transfer speeds with regards to your link speeds.

As for your config, can you post an export from your capsman manager device? This provides more details to be able to help.

I don't really see anything wrong with the config, but I would definitely see if capsman forwarding is your issue. Check the cpu on your ap and router while doing iperf speed tests.

You might want to see if you have overlapping channels too close to one another since you are using 80MHz channels. Many times going from 80 to 40 will help if there is a lot of inference. The link rates will be lower, but the speeds will be more consistent.

If you set the data path to be local forwarding=yes, be sure to delete the cap interface and reprovision the radio via capsman.

thanks.

I'll try set the channel to xx.

and try again use 'Local forwarding".

one more question about this "If you set the data path to be local forwarding=yes, be sure to delete the cap interface and reprovision the radio via capsman."
you mean delete cap interface from CAPsMAN - configurations ?

Don't use wpa-psk as authentication-types. Ever. Only use wpa2-psk.
不要使用重叠(也在5 ghz)和渠道use specific extension channels (use Ceee instead of XXXX).

In real life (no matter what hardware you use) you will generally get up to 1/2 the transfer speeds with regards to your link speeds.

As for your config, can you post an export from your capsman manager device? This provides more details to be able to help.
First for the OP, where do you see this 866 speed that you keep stating and specifically what does this have to do with wifi throughput??
Reading the spec sheet, the 2.4 speed is stated as 300, and the 5ghz speed is rated at 1300.
I do note they say AC1600 which seems nothing more to me that 300+1300=1600

If you are talking the advertised WIFI speeds then you havent paid attention or have been duped by marketing.
Typically one will see TWO WAY speeds advertised while we as users tend to think one way, up or down.
So, lets say for the 5AC, as biomesh pointed out the expectation should be a starting point of 1300/2= 650 one way speed for the 5ghz network.
However that is theoretical and doesn't take into account normal propagation losses through air, cabling etc,"
Then we have to factor in any walls or physical obstacles in the way of the signal
Then we have to factor in any electrical appliances and lighting or currents in the house that may affect/interfere with signal
Then we have to factor in any competing devices such as other WIFI radios.

The best rule of thumb is the 1/3 rule. 1300/3= 433 should be what you are seeing give er take on the device.
In your case then, there is definitely some issues. With a LOS connectivity you should reasonable expect to get +400Mbps.

I have a capac and through two walls and one cabinet(solid wood) and all the other issues about 40down and 30 up on 2.4ghz and 15 down and 10 up on 5ghz.
and yet the unit drawing a straight line is not that far from the receiving unit (firestick).
867/3 = 289是我应该能够合理的get for 5ghz
300/3= 100 is what I should be able to reasonably get for 2ghz
Which goes to show you cannot overcome physics magically of obstructions and interference.

Link speed is 867Mbps but real throughput is normally around 1/3 of it.

Not sure what requirements (and expectations) you have, I get a solid (little over) 400 Mbps on my cAP ac.

I’m able to get about 480mbps from my cAP ac, Audience and hAP AC2, 3 of them has the same maximum speed.....

Hah, get used to it, it's "pretty" decent for mikrotik to give you 200mbps for 866 clients.
Wanna wireless better - search for other options. That's as it is.

P.S. And don't believe these ones upahead telling about 400-480 mbps - I've reached 750 mbps with wAP AC for 1300mbps client - but that was only !once, for a couple of minutes and I couldn't repeat that result, no matter what.
Now it's only ~260-280 mbps, with the same client, same wifi card, same wAP AC and the same settings. Because mikrotik wifi perfomance depends on moon phase, weather...everything!

Please speak for yourself...these results I have since a very long time. WiFi is a shared medium, you can't compare to other situations based on personal experience.

I know that yours 400 mbps doesn't mean anything, since I've had 42-48 MB/s couple of months ago, then it degradated to 30 MB/s, now it's only 10MB/s - and nothing literally changed in the area these wAPs are operating!
So just wait half-a-year when you have maximum 280mbps, afterwards firmware bugs will come...

Agree, u may get very high speed for a moment, then dropped to a much lower speed, it has nothing to do with setting, no magic here.

Besides your personal frustration presented as being the standard situation, you mix up units.
I'm not trying to have a discussion, I'm just telling you that your experience is...your experience. I.e., I'm running this site since December 2019, and tested a lot of firmwares and settings.

"Because mikrotik wifi perfomance depends on moon phase, weather...everything!"

No it's not depending on that. It's depending on the specs of your client device, on the AP settings, on the environment, and on the electromagnetic field around. And it might depend on your tests (testing towards cloud based servers is testing the whole connection chain, not your wifi performance)

客户端设备:1300 mbps需要空间streams and MCS9 encoding and 80MHz channel width. Most client devices are 2 spatial stream capable. So 866 Mbpsinterfacedata rate is then the max.

AP settings: many try things, learn and copy from others, that come from totally different conditions, and ruin their wifi performance. To tune this you must understand what it means if you set something. You must understand the wifi extreme large overhead (indeed very often 50%, for small packets over 90%). You must understand the scarcest resource: "air time". How co-channel interference works, how aggregation is absolutely needed for high speed and low overhead. How adjacent or overlapping channel interference is just totally killing your performance.

environment: And there is still that diffraction/absorption/reflection by walls, objects or persons around. And the non-wifi 2.4GHz and also 5 GHz sources. Even TX power and received signal strength can be of a major influence. And stronger is not always better! It will all reduce the TX/RX CCQ, and make wifi step down in encoding and interface rate. (CCQ is related to the number of retransmits. Retransmits reduce the net data rate also.)

electromagnetic field: yes there are many other sources in those bands that you do not see with a SCAN. Using "Snooper" is already an eye opener and this is still understandable wifi. "Freq usage" is another tool to check.

If you use "XXXX" as setting on the channel selected, you didn't get it yet. You don't care what channel is used, because you have no control this way. And you just allow statistics define whatever your performance will be one day, different from the other day. The number of possible 80MHz wide free channels is VERY limited. And wifi interference happens at a much lower signal level (-96dBm) than non-wifi noise interference (-86dBm)

Wifi performance does not depend on the moon phase, but it does depend on the Solar Cycle. But most of all depends on loosely defined configurations, and use of irrelevant tuning hints. (And no, "auto" is not giving you the best wifi experience, not even close, it can be very contra productive for its own and even other nearby wifi performances)

If you want to see what wifi overhead is for a small packet (no-aggregation) , and how it even gets as big as 99% for a 90 byte packet when having 866Mbps interface data rate. (That's is 8 Mbps payload data rate in the best possible wifi condition, and limited to one direction!). For high throughput: aggregation needs to be turned on. (Not clear where numbers are hidden in RouterOS for 802.11ac)

Nice link bpwl. Couldnt help notice that HELP and CAPsMAN are in the same sentence, seems way to frequent for a mature product or useable product of code. Is it the software, lack of clear guidance in writing, or something else....

E.g. On a wAP ac with RouterOS 6.47.2 on 5 GHz (80MHz, 5180) and a Windows 10 laptop with Intel AX200 which is right next to the wAP ac (<20 cm) and is connected at 866 Mbit/s, the maximum download is 287 Mbit/s and maximum upload is 171 Mbit/s. Those are the maximum values I get with iPerf3 after some runs to a local 2nd computer which is connected to the same switch as the wAP ac. WPA2 PSK with AES is being used with default settings on the wAP ac.
That´s without CAPsMAN.

I think CAPsMAN is designed/tuned for the environment with multiple AP's and quite some clients attached, using moderate speed and stable response time. I see things as MSDU=2048, HW-retries=3, MPDU only on priority 0, no guidelines for VHT setting in wiki nor MUM presentations .... . It handles some interference and the hand-off if too many clients are on one AP. Every tuning is a trade off.

If I use the "car" metaphor, this is a SUV with soft suspension, automatic gearbox, AWD (not FWD), large load capacity, 2000kg idle weight. But then we test it as a racing car. (MAX PHY interface data rate, wide channel, single AP, single client ... to get most throughput out of 866Mbps interface data rate).

Would love to know where RouterOS has it's counters for aggregation ... as this explains most of the statements here ... varying test throughput from 20% till 70%. And if it is not tested in 1 AP- 1 client radiosignal free environment, but real all day deployment, then that value will drop very deep and be very volatile.

MT Wifi = Mystery
Mystery = Lack Confidence
Lack Confidence = Less Sales
销售额越少= Normis买不起奔驰
Normis Cannot afford mercedes = Normis' partner dumps him and finds another
Normis' partner dumps him and finds another=Normis depressed
Normis depressed=Normis sees shrink
Normis sees shrink=Shrink determines the root problem is wifi
Shrink determines the root problem is wifi=Normis finally deciding to fix wifi
Normis finally deciding to fix wifi=Normis hiring bpwl on MT Wifi Team
Normis hiring bpwl on MT Wifi Team=Improved WIFI Performance/Documentation/Tuning/Stability
Improved WIFI Performance/Documenation/Tuning/Stability=Increased Confidence
Increased Confidence=More Sales
More Sales=Normis can afford mercedes
Normis can afford mercedes=Normis' ex-partner does not come back.

The moral of the story is that if MT hires bpwl now!!!, ubiquiti will go out of business and Normis will be able to keep his partner!!

MT Wifi = Mystery
At least MikroTik Wifi is "wysinwyg" . ("n"=not) This gives many mysterious performance results.
Just remembered that the (very) old "Microsoft Network Monitor 3.4" does show the Beacon content for the channel used. Wireshark requires a special dedicated wifi interface in Windows to see more than the payload. But you can do it with the old Microsoft software. (it adds a driver to the wireless interface ...). It dates from Windows Vista, but works well in Windows 10.
Klembord-6.jpg
This could lift the tip of the veil somewhat.

Take this as an example ...(2.4GHz)

wireless data rate default versus configured. Only the selection default is changed to configured. The default settings are left untouched.
Klembord-2.jpg

Klembord-3.jpg

But the rate at which the beacons are sent changes from 6Mbps to 1 Mbps, even with mode "n-only" ... taking 6 times more airtime. (Airtime for beacons ... there is a calculator that learns that 16 SSID on AP's (e.g. 4 AP with 4 SSID each) at 1 Mbps beacon rate, take 50% of all the airtime of that channel)http://www.revolutionwifi.net/revolutio ... lator.html
All this reduces the wifi throughput if multiple AP's are in reach/ just can be decoded. (I see that ALL ISP delivered modems in my neighborhood transmit at 1 Mbps, and every house has one !)
Klembord-4.jpg
Changed rate from default to configured on Mikrotik-waP , and this acts on its slave interface guest30 as well.

Klembord-5.jpg

So I'm very curious now what else can be revealed from that beacon ..... And, oh yes, one can explain why the beacon rate changed, only, it was unexpected behavior.

Try setting
1. the basic rate to 12 Mbit/s
2. mode g/n.
3. disable all b rates (supported+basic)
5. activate all supported rates >= 12 Mbit/s

Let´s see what beacon information you get afterwards.

I agree with everyone here Getting 'good' to 'great' performance with Mikrotik Wifi is a bear. Compared to say generic Comcast modem, where its instantly connects and has high throughput, I could play with Mikrotik for weeks and not get the same performance. I've been putting wifi networks together for years from Mikrotik, UBNT, Ruckus, Meraki, and every generic consumer brand you can think of, and Mikrotik just isn't one of the top contenders. I don't know if its hardware, software, or the combination there of... but seriously, the wifi documentation for a 'best practice' install for SMB or Enterprise is so lacking, I'd never install Mikrotik APs outside the home unless it was a point to point scenario.

I know what to expect.

But even then, other things are very confusing.default<->configured
灯塔与默认6 Mbps,降到1 Mbpswith configured if allowed.
Looking in the registration-table CLI print

/interface wireless registration-table print stats

default: tx-rate-set="CCK:1-11 OFDM:6-54 BW:1x SGI:1x HT:0-7"
configured: tx-rate-set="CCK:1-11 OFDM:6-54 BW:1x SGI:1x HT:0-7"
configured with b-rates removed: tx-rate-set="OFDM:6-54 BW:1x SGI:1x HT:0-7"
default but with b-rates removed in configured: tx-rate-set="CCK:1-11 OFDM:6-54 BW:1x SGI:1x HT:0-7"

configured for 12Mbps as basic rate (and minimal supported rate.): tx-rate-set="OFDM:12-54 BW:1x SGI:1x HT:0-7"

Beacon as expected, (and neighbors ISP AP's as well, decoded on channel 12 !!! (=co channel interference, 20 dB more sensitive for interference than adjacent channel/noise))...

Well , I have done my homework. Enjoyed reading beacons from some AP's around me. And all falls into its logical place.
That old Microsoft Network Monitor cannot decode the ac beacons, but the capture file is readable and decoded by wireshark.

It's easy to analyse the internal workings of an otherwise closed (no info in the admin interface) or foreign AP's.

What I have learned is just explaining the wifi performance. Go back and see the importance of aggregation in a way to avoid the 99+% overhead, and then see the numbers.
I compared the MKT wAPac, hAPac2 with a similar cost old/obsolete Draytek router 2132ac.
We have A-MSDU (or MPDU) size, and A-MPDU size as parameters for aggregation capabilities. HT and VHT are different according the standards. What do the AP beacons tell us?

MKT 5 GHz ac is a superset of the 2.4 GHz n (HT) set. The HT sets are identical.

MKT HT: : A-MSDU limit = 3839 bytes , A-MPDU limit = 65535 bytes
MKT VHT: MPDU limit= 3895 bytes , A-MPDU limit = 262143 bytes

Draytek HT: A-MSDU limit = 7935 bytes, A-MPDU limit= 65535 bytes
Draytek VHT: MPDU limit = 11454 bytes, A-MPDU limit= 1048575 bytes

That 8192 number in the default setting in RouterOS for A-MSDU is somewhat misleading.
Like going to b-rates for "onlyN" mode basic rates is not intuitive. It is in the wiki, but not expected, as g/n correctly avoids b-rates.

EDIT: even the "onlyg" is as inconsistent as "onlyn".

Tue Sep 15, 2020 11:22 am

But .... don't jump to conclusions. The slower throughput is not directly proportional to these numbers.
If you drop them in the calculators, then all is fine as long as A-MPDU is above 32768 bytes. A-MPDU is the ultimate payload, that goes in airtime competition with the overhead.
To drop the theoretical throughput on an 866 Mbps interface to 290 Mbps as absolute max, limiting A-MPDU to 16000bytes will be exactly what is needed.

So maybe the 3839 byte limit is not a problem as long as A-MPDU compensates for the smaller MPDU(A-MSDU). However the control over A-MPDU in RouterOS is minimal. Only 8 toggles on/off for each of the 8 user-priority values. And by default only set for priority "0" , luckily by default all data packets are just user-priority "0". What on the other hand limits the WMM functionality. (By the way the WMM Contention Window and other values in the beacon are just the standard values. Again RouterOS interface gives no viiew or control over this.)

https://gjermundraaen.com/thewifiairtimecalculator/
http://www.arubanetworks.com/assets/vrd ... RD_V2.xlsx(there is an excel error in scenario 2 not using the set interface rate)

https://howwirelessworks.com/wp-content ... _Guide.pdf...a very interesting Theory guide, applied for high density but the theory is always valid, so it can be applied to the file transfer, streaming and speedtest context. And the practical examples make me wonder ..."The MPDU-per-TXOP ratio is approximately 60 at 1 STA,...", or how many MSDU's would be sent in a payload/TXOP/A-MSDU with RouterOS. 64 MSDU? An A-MSDU of 262000bytes ??

This part (the overhead mitigation) was missing in the earlier youtube presentation .... it's not used in the high density scenario, but the theory applies.

According to the dev who helped to port OpenWRT (Robimarko) to the hAP ac2 and other IPQ4018 Mikrotik products they're using QCA drivers but their AP implementation it's not standard compliant and lacks the wave 2 feature set.

https://forum.openwrt.org/t/can-open-so ... s/72832/40

I think they haven't migrated to something like hostapd to avoid deprecating all their propietary stuff like Capsman, hotspot, NV2, nstreme and so on (most of those can be rewritten to support the new implementation).

PD: I know I can just enjoy my OpenWRT powered ac2 and leave this forum but advanced routing features (like VLANs) are more polished on ROS.

One posting later it says:
It´s hard to believe, but MikroTik really writes their own wireless driver. MikroTik regularly confirms this in it´s forum, e.g.:

viewtopic.php?t=145047#p713800
"You are right, that MikroTik made wireless driver doesn't have Wave2 support, so new chipset benefits are not there. We are working on a new driver."

According to the dev who helped to port OpenWRT (Robimarko) to the hAP ac2 and other IPQ4018 Mikrotik products they're using QCA drivers but their AP implementation it's not standard compliant and lacks the wave 2 feature set
One posting later it says:
It´s hard to believe, but MikroTik really writes their own wireless driver. MikroTik regularly confirms this in it´s forum, e.g.:

viewtopic.php?t=145047#p713800
"You are right, that MikroTik made wireless driver doesn't have Wave2 support, so new chipset benefits are not there. We are working on a new driver."

PD: I know I can just enjoy my OpenWRT powered ac2 and leave this forum but advanced routing features (like VLANs) are more polished on ROS.
We really need to get hAP ac2 into official OpenWrt branch...

@hiedarren
1/3 speed is normal for MT,2/3 speed isnormal for others
...

Lets think about that statement.
If 867 is the advertised two way speed, also called the 'marketing speed'
The best one way speeds physically possible are 433. AKA 1/2
Factor in some losses, and the 1/3 rule is realistic for a plain wifi 5 device which yields 289.

Now with new features and capabilities added to wifi 5 and standard on wifi 6 etc, the losses are minimized but only to a certain extent on other devices using standard chips and programming.
Mt with the capac and proprietary programming has fallen short in stability and speeds and perhaps some folks can see more than 300Mpbs but its probably rare.

But to state someone is getting 2/3 of the advertised speeds LOL. I just need you to explain the physics on that one or retract your statement.

By the way for roughly the same price point I changed from capacs to tplinkeap245v3 wifi 5 access point that can also read vlans.
It has an additional chain and thus has 1300 advertised speeds and 1/3 = 433 and I am able to achieve that plus some due to Mu-Mimo functionality added etc...
But I can say I have never achieved anything over 650Mpbs (1/2), let alone 866Mbps.:-)
Within LOS I certainly can achieve 600 down 500 up.

The math is not difficult, it is already done, you just have to fill in the numbers. THE difference between MT and others is the MPDU size (and corresponding A-MPDU).
WinBox suggests 8192 is used , we know from the AP's beacon that it announces 3895 (the lowest standard value, while others claim 11454 bytes (the highest)
CAPsMAN claims 2048 (!)

Filled in the calculator found here:https://gjermundraaen.com/thewifiairtimecalculator/
More specific URL on that page for the spreadsheet:https://gjermundsblog.files.wordpress.c ... ion-1.xlsx

And assuming 8 MPDU buffers in one A-MPDU , it gives recognisable numbers: theoretic max for MT standalone and others of376Mbps and 600Mbps
This 8 MPDU is just an assumption, calculated with this larger packet and the mandatory A-MPDU "block ack" for the 8 MPDU in one simple ACK packet is included.
(There is no 50% send/receive division. This is like a roundabout, every lane tries to get on it and has equal chances (unless WMM is used, then there are priority drivers)
Klembord-2.jpg
If one wants to extend this to triple stream .... easy just replace 2 with 3 and you get speeds like 434Mbps for MT and 776Mbps for others.

And now we optimize when the conditions are good , rising the basic rate from 6Mbps to 24Mbps .... becomes 544Mbps and 844Mbps for triple stream
For dual stream the data rate changes from 376Mbps(MT) and 600Mbps(others), to 424Mbps and 640 Mbps, when basic rates is 24Mbps.
And down to CAPsMAN, or anyone who reads the forum and sets it to 2048, ... 2048 byte MPDU, 6 Mbps basic rate, dual stream ...... 247 Mbps
Setting A-MSDU=MPDU to 2048 is a good thing to do, for some conditions, not if you want max speed.

That's without any disturbance (but RTS/CTS included, as the wide channel of 802.11ac requires AFAIK.) There is some air-time loss for the beacons, with beacons at 6Mbps, count on 0.5% per AP- SSID transmitter, at 1Mbps it is 3% !

600/866= 69% (others and wifiwave2)
367/866= 42% (MT)
247/866= 29% (MPDU=2048, A-MPDU=*8)

PS: If you do want Microsoft Network Monitor 3.4 you better hurry. Microsoft removed the install file from their archive. Softpedia still has it .... NM34_xxxx.exe
微软网络监视器没有NPcap司机我们rk on my new laptops (WIN10, 64bit). So capturing wifi beacons and management packets is gone.
The Free "WinFi" wifi monitor stopped working everywhere, also the old installs.

但没有担心。任何Mi雷竞技网站krotik AP能做到。使用"Wireless Sniffer" on a WLAN interface catches those. (This is NOT the Sniffer in Tools!)
Saved in a file, and downloaded for Wireshark, gives again the decoding of the "beacons".

EDIT: Well I have another way to collect all Beacons in the area just with the laptops. With the free InSSIDer software , the "File->Export Summary..." creates a file with all the beacons received in all bands and channels, one beacon for every SSID+AP combination. The file is decodable by Wireshark, and it does not contain other data packets.

So bpwl, from a practical standpoint are you saying the MPDU is only configurable via capsman?

Not really. (I'm not a CAPsMAN user, maybe I should set one up on one device just to see what it does on performance. As people in the forum say the WLAN settings have no importance if CAPsMAN is used, looking at the Beacon would be what I would check.) A-MSDU and A-MPDU parameters are not in the wiki for CAPsMAN. I read in this forum (and some other blogs) that CAPsMAN sets the AMSDU size to 2048 by default. (Some explanation is that it then fits into the wifi MTU. But the 802.11 standards and beacon fields don't have such a value for MPDU (=A-MSDU).)

Setting A-MPDU on or off is in the WLAN interface. By default only for priority 0 !
0,3 (BE: best effort)
1,2 (BK: background)
4,5 (VI: video)
6,7 (VO: voice)

Setting the A-MSDU=MPDU size and threshold is also there.
Klembord-2.jpg
The priority itself is set in mangle rules, as it is not received or transmitted, It can be calculated from the DSCP bits. (DSCP travels with the packet.)

So what are you recommending for the capac
for optimal numbers to put in those two top settings (AMSDU entries),
and what you recommend should be checked off in the below settings (AMPDU settings) .

Question for me still is how to implement the priority mangle rule in an efficient way, when we use a simple (C)AP connection, withbridged ethernet and WLAN interfaces.
Packets are processed by CPU because of WLAN interface not on switch chip, they do not pass the firewall by default, and if we set "use IP firewall" on the bridge, can we still Fastpath or Fasttrack, or is there no need for this? What chain to use? "Prerouting" or "Postrouting"? Connection-mark for faster selection?
Is setting DSCP of any use here?

bowl, I too wondered about this. Because with fast path, mangle is not used. After days of usage, I have barely a few packets that hit the mangle.
Also, in your example, you only set priorities 0 to 5. What about 6 & 7?
And why is guard set long and not both?

What I tested so far, for "use IP Firewall", following steps are needed:

- disable HW offloading (it may disable itself because of conditions set (I often play with bridge horizon to separate the 2 WLAN interfaces) , but OK to be sure)
- no fast-path on interfaces
- no Fast Track in the firewall
- enable "use IP firewall" on bridge settings
- "outgoing" chain for the 3 bit DSCP mangle rule or other "priority" rules
- counters in firewall increment for local router traffic only so far, not for the forwarded traffic (still not enabled here ???) Idem for Torch. Not in FW tracked connections. Have to check again.

While doing all this I saw thebridge Firewall filterrule to just SET the priority (no DSCP here:-(). Good for an experiment when surrounded by video streamers on other brand AP's that do support the WMM priority. I think the regular best-effort will not get a fair share of the transmission slots under heavy load conditions, as VI(deo) priority uses much smaller Contention Window timers.viewtopic.php?t=183101#p912637(Yes I'm mixing several posts, this is more for that other post)

Long guard, is a left over of my previous experiment where a Raspberry PI refused to connect. ('Guard', 'distance' are known causes in some cases. Here it was because the VHT 0-7 basic rate was enabled. (It's disabled under 'default', just setting it to 'configured' enables it). So no, leave Guard on "any"

Why 4-5 and not 6-7.? Video 4-5 is high volume (I see 6Mbps even 12 Mbps per viewer) so aggregation is important. And Video can handle some jitter or buffer delay.
Audio 6-7 does not like jitter or interruptions for agggregation at all, and the volume is much lower. If I want to test highest priority throughput then for sure A-MPDU must be set.
(Not calculated what the lower TXOP value for 6-7 means with this)


Setting the priority on 5 would make it all VI(deo) priority. To be tested when under heavy load and video competition ... would be very interesting to understand if not supporting WMM priority out of the box, is giving the MT AP a disadvantage in crowded environments or not.

Interesting......
- enable "use IP firewall" on bridge settings
After I changed that setting, my mangle for set priority suddenly sprang to life. It went from 50 packets over weeks, to incrementing rapidly.
No other settings changed.

So I have: WMM on, 0 to 5 ticked for AMPDU, and a post mangle rule on priority set From DSCP High 3 bits.

I'm assuming the data coming in from my CCR passing through a queue picks up the DSCP, and once it hits the CAP, priority in the CAP is set from those bits?
Do I need anything special set in the CCR gateway router to ensure DSCP is set? Is that set from the queue or from the ISP/source of the data?

In my CCR, I'm using fq_codel. There are no DiffServ options for that. But Cake does have various DiffServ options. From a separate topic on here, the guru of fq_codel & cake, provided some settings which I have chosen. But my question is, does fq_codel set DiffServ?

It is the role of the edge router (facing Internet) to check or set the the DSCP, for the rest of the local network.
There are probably some mangle rules needed to set DSCP if it is missing or stripped by the ISP. VLAN are also used to set DSCP.
DSCP values can come from the well known ports, or just defined by the application.

Have to check again.
OK found it. VLAN filtering was enabled on this bridge, so "use IP Firewall for VLAN" had to be enabled as well.
For some reason Fasttrack was never used (Schrödinger's cat ? Because of looking with tools?:-)), dummy counters didn't move, copying the "special dummy rules" gave the non-Fasttrack counters running as expected. There was no need to remove the Fasttrack rule but I disabled it to be more deterministic.

Time for some tests ... two mangle rules used, first one to set DSCP on 46, and the second to set priority based on the 3-high bits of DSCP.
Windows10 PC, 64bit, only gives 150Mbps due to poor connection and accordingly lower interface rate. (MCS04 / 05))
There is also an "Omnitik ac" as client device, on another floor, send or receive in UDP was a steady 353Mbps. Difference between "DSCP undefined" and "DSCP=46" was the later slightly better. (In theory , by setting AIFS(VI) in de spreadsheet it's 3 Mbps better)
But those numbers are very close to the MAX possible values. (Free RF frequencies here, only competing with 2 laptops and 2 smartphones on the same AP). I'm not in need here for this WMM "turbo".

Disabling the extra A-MPDU flags gave 34Mbps in send, but receive was not affected (just as expected). I dIdn't leave out a digit, it is a 2 digit number: 34Mbps. (Theoretical max without AMPDU is 75 Mbps with 866Mbps-80Mhz/2S/SGI in the XLS spreadsheet, but interface rate was not steady).

Torch can not show the "priority", so setting DSCP helped in seeing life in Torch what connections were affected by the mangle rules.

End of experiment, now time for learning how well internet video sites are tagging their traffic with DSCP.
