I had a bad wifi reception so I bought an external access point -> ALFA Network AWUS036ACHM.
In order to force the connection exclusively with the new interface, I added 'denyinterfaces wlan0' and now ratos only uses the new wlan1 interface.
All works great after a reboot but after sometime , usually 30min, I loose the connection with the printer and the defaut SSID 'ratos' appears.
Can somebody help me understand what is happening?
