Please help

AP650 when installing 160Mhz keeps disconnecting, unstable
Whether setting auto channel or fixed channel (36,40,44,48) all have the same situation: stable connection for about 1 day, then lose connection, then reconnect, keep repeating the situation like so. Don't know for what reason?
If I install 80Mhz, it's stable connection
Has anyone encountered a similar situation?
Please help

160Mhz is combining a large amount of separate channels in to one, essentially, and any issue or congestion on any one of those channels will then be a potential issue for all of your traffic. You’d want to keep an eye on a spectrum analyzer or similar tool to see if you can pin down an issue on any of the channels you’re combining/hoping to use.

 

You can also check the channel cost of each channel with the command: 

show acsp channel-info detail

This shows us the health of each channel. We want to focus on the channel cost here, the lower the channel cost the better. This channel cost is what the auto channel selection feature uses to select the best channel for your APs to be on. Some thing to keep in mind with this command is that it can only take in to account traffic on other Extreme Networks APs, so if you are sharing air space with a neighboring network or individual hotspots, this output may not be showing the entire picture.
