Deployed a large MR system, out of 500 clients 20 wireless phones have connectivity issues, appears to only be to the pbx. Yet the vendor is stating they have SNR issues, that i need to manually configure TX power on AP's.
Just looking for communitys thoughts on manually messing with Tx powers, i assume a site survey would need to be done regularly to adjust settings.
Its a larger 40AP environment varius TX powers throughout the day. MR33 in each room.
Phones do not support FT, only pay nice on 2.4 as well. Ascom I 62 is the model.
They started dropping connection to the PBX and messaging server.
All i know is that the SNR for the client is usually perfect, and ICMP from AP to phone never drops. Also the wireless health is pretty solid, no spectrum concerns. I have tried multiple authentication methods, even open nothing changes.
Sometimes making clients roam when an AP is overloaded can cause this. You can check the event log to see if the APs are asking phones to roam because of load.

You can disable load balancing in the RF profile:
