Low Data Rate for AP7562 ann AP 7532 AC Radio

[izzeterol]

Hi ;

I am trying to solve Wing AP problems in an hotel for one year. We cant get any support especially in Turkey for Wing products. 

We had so many problems about download speeds and intermittent disconnects. Some engineers came from Extreme HQ in Turkey and told that there are network issues, not about Wing. But when we run an Aruba AP in the same networks we hadnt seen any problem. 

I tried to solve the issues by searching the support pages and community topics. 

But one problem is really disturbing. 

As you can see the pictures below for AP7562 and AP7532 radio2 i cant get maximum data rates. When i connect an Aruba 275 in the system same location, i can see maximum data rate 866 Mbps. With same phone when i connect to 75xx AP’s, despite being near the AP and see -45 dbm, i can only see maximum speed 96Mbps in channel 100.

Hi izzeterol,

Above KK is me.
I accidentally replied to you with my private portal account which was created when I was Extreme customer. Sorry if I make you confuse...

Thank you for providing command result.
From “show wireless radio detail”. I can see AP is operating with 80Mhz and speed can be up to 1.3Ghz with 3 stream. Normally, Android only support 2 stream, so 866 is Max as you said.

From “show wireless client detail”, AP understand that this client capability is only 802.11an, 1 stream, and 40Mhz channel width. To reach 866, it should be 802.11ac, 2 stream, 80Mhz.
This info is based on conversation between AP and client during association phase. I suspect something wrong during at that phase. *Probe request/response, association request/response, authentication request/response.

I think we need further investigation including wireless packet capture. You may open GTAC case with valid support entitlement. You will need to provide tech-support file, wireless packet capture. They will inform you what they need for investigation once you opened case.

Hello,

I am currently running an AP7532 with wing software 5.9.8.0 and I am able to see that we don't meet the throughput requirement to 80.2.11 ac as explained here in the post.

On my configuration, I am running the following settings on radio2:

- Data rates custom basic 3- mcs-1s mcs-2s mcs-3s 

- Data rates qam only

- Channel 44ww

By doing iperf3 testing, we are able to see that download/upload over TCP and UDP don't go higher than 220 Mbps, whereas the wireless client statistics show that phy rates is 1.3 Gbps.

 
You mentioned that further investigation had to be done. What was the result, and what are your recommendations for improvements ?

Thank you for your help.

Regards,
Arthur

Yes, the point is i know the capabilities of 7532 and 7562 but i cant see the maximum data rate as 866 Mbps. When i plug Aruba 315, same phone can give the maximum data rate 866 but in Extreme AP’s i cant see the AC data rates.

When you said me to change the operating channel, i made 100ww and the data rate increased only 150 mbps. (When dynamic channel it was only 96)
