Issue: Client is frequently reporting roaming issues. I have enabled client match, 802.11k,r. This is a 7205 controller with 315 AP. Client device 802.11ac(Oneplus mobile). No signal issue. SNR is perfect

 

Any suggestions airheads?

Your 2.4ghz band power is too high if ClientMatch has to band steer it all of the time.  The 5ghz band range for your radio should be at least six above your 2.4ghz band range. 

 

Mu steer is the steering of a multi-user mimo client.

Re: Client Roaming issues

nu mimo is the least of your problems.  The power range of the 2.4ghz radio vs the power range of the 5ghz radio is your problem.  The fact that client match has to steer your client from the 2.4ghz band to the 5ghz band all of the time means that your 5ghz band radio is not high enough.
