Wireless Access

Hello Everyone

 

Maybe someone are have facing the following issue, we have a deployment with ArubaOS 8.5, MM, 2 x MC 7205 and AP-515.  But we have some users with macbook pro complaining about a slow network connections.  But when they test the connection with an simple internet speed test, they do have 130mbps download and 180mbps upload which is very fast for us.

 

Tracking the issue a little but I found that this clients are moving between "awake" state and "power-save" state when running the following comand:

 

show ap debug radio-stats ap-name <ap-name>

 

 

does anyone knows if there is way to keep the client on a "awake" state?

 

thanks in advance :)

The PS_State output returned from the command used is for the AP's state (Awake / Power Save) and not the client.

Please Refer AOS 8.5.0.0 CLI Guide (Page: 1373)

 

With regards to the clients,

Is UAPSD enabled in the SSID profile for this specific ssid ? This can be checked using the below command.

 

(config)#show ssid-profile <name of SSID profile>.

This may be the issue. Is it possible to disable this option and observe behaviour(If it is a production network try it during downtime).

 

This can be disabled in the SSID profile. I recommend creating a test SSID profile with UAPSD disabled and testing before making any changes to the production network.

Thanks for help :)

 

In fact this is kind a pre-production enviroment, we are deploying 100 Aps but testing now with the 25% of the clients. They know this is not a production ready installation :)

 

thanks for the tip, we will monitor the behavior this week.

greetings

Great. Let me know if this works.

Wireless device “sleep” for very short periods of time to preserve battery life, which is part of the standard. If you plug a laptop in, it will sleep “less”. This is all fairly typical. UAPSD is fairly device specific and should not be configured in the vast majority of situations. It should not have a bearing on your issue.

Your issue is possibly because you are running 80mhz channels that could be interfering with existing neighboring channels and affecting your performance. It is not typical to run 80mhz wide channels with a lot of density because there are not enough channels to do that without causing cochannel interference and contention, that affect performance. I would try to run 40mhz channels and also enable DFS channels in the regulatory domain profile, for the highest performance.
