I have a weird issue with the wifi for some of my RPis. it gets disconnected et reconnect each 5 minutes and I don't know what's causing this.
I found those lines every 5 minutes in my logs :
Code: Select all
wlan0: CTRL-EVENT-CONNECTED - Connection to 00:24:d4:62:16:58 completed [id=0 id_str=mbxwpa]
p2p-dev-wlan0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD
wlan0: CTRL-EVENT-DISCONNECTED bssid=00:24:d4:62:16:58 reason=0 locally_generated=1
and here is the iwconfig output :
Code: Select all

I have another box in another network that works perfectly. and here is its iwconfig :
