Wireless networking is not working consistently on my dual or quad udoo boards. I'm running the ubuntu image (1.2). The behavior I see is that when the board boots it will associate and acquire an IP address but after some time (several hundred seconds) it stops working. In the kernel log I see: ieee80211 phy0: wlan6: No probe response from AP [...] after 500ms, disconnecting. I have noticed that this problem does not manifest on /all/ wireless networks, but does so consistently on at least one. (No other regular computer has a problem on this wireless network however). The APs in question are Cisco. I'm able to work around the problem by turning off power management this way: iwconfig wlan6 power off but unfortunately I've yet to find a means of turning it off automatically (NetworkManager dispatcher.d / udev rule). Seems like both of those should work however I still find that after the network comes up power management is turned on.
Re: wifi stops working (ieee80211 phy0: wlan6: No probe resp Yes, heard of this problem before and the only known workaround for those suffering this is to turn the power management of the WiFi off using iwconfig.
