Re: Connection beetwen mesh portal with mesh point is intermitten

Might be some DFS issues (weather radar or similer) - try using other 5GHZ channels , or disable 80mhz and use 40mhz only.

 

and <> please read bellow comment:

With IAP there is no functionality that prohibits an AP from changing channels when mesh is enabled (not really for AOS either). So if there's no clients on the 5Ghz radio (assuming you have client aware enabled) if the AP scans for 5Ghz and finds a 'better' 5Ghz channel, it will move, even with mesh enabled, and it's obviously very disruptive. In many cases the 5GHz mesh for instant is used when they just need to reach the last leg for client access Aps, but for bridged network backhaul, when you want the 5GHz radio to chose stability over the best channel, a static assignment should be used. It would be good to have some kind of logic where 'is mesh is enabled on the 5Ghz radio, only change channel if absolutely necessary'.

Please obtain the tech support from the AP to see if there any clues as to why this is happening.  We need more information.

"show tech-support" would be the best command to capture everything.

How far apart are those access points?  It says that the RSSI is 50.  Also type "show log wireless all" and "show log system all" to see if there are any clues why these access points are disconnecting.  Also, "show ap tech-support ap-name <name of ap>" for each AP, to see if there are any more clues.

Re: Connection beetwen mesh portal with mesh point is intermitten

length between APs is 110m and there is no obstacle between them,

 

i attach the log for "show log wireless all" , "show log system all" , and tech supp for each APs
