Best Practices for Min Transmit/Max Transmit Power Levels

[ Edited ]

Hey All -

 

Had a few quick questions since transistioning to the Aruba line, have 4 IAP-225s in service spread across two floors in approx 3000 sq ft of space (2 on 1st floor, 2 on second floor - ceiling mounted)

 

It appear the min power level is set to 18 and max level is set to "Max" by default -  with those settings I get the following:

 

IAP.tiff

Note the utilization across both 2.4 and 5.0GHz

 

I have client match enabled but it doesn't seem to be balancing the clients all that well since the clients are near all 4 access points.  

 

Any suggestions for optimizing the configuration?

Under the arm tab uncheck 80 mhz channels. Make your min 9 and your max 15, and then check the utilization.

Thanks - out of curioisity, I was previously informed to enable 80Mhz (to increase WiFi speed for connected clients - all 4 APs are connected to a switch with a 1Gig by 1 Gig fiber connection.

 

Is the 80MHz causing the utilization issue?

 

Thanks

Utilization is an issue on the access points that are both on channel 32E on the 5ghz band. That is why 80 MHz should be unchecked

Utilization is a problem in the 2.4ghz because the poer is too high. Other non WiFi devices also reside on the 2.4 ghz that exacerbate this problem. Maybe you should make your max 12 since you have such a small space.

Contention is greatest at the wifi layer, so if you do not reduce contention, you will not get anywhere near wired speeds.
