Hi,
Not sure if this is a correct forum to discuss but I am facing an issue on Ubuntu 16.04.1 64 bit kernel 4.8.0-39-generic using wifi adapter AR2413/AR241 which is running ATH5K version 4.8.0.39-generic. If this is not the correct alias, please excuse and suggest the right alias.
4.8.0.39-generic is not currently supported. Perhaps you could try upgrading to a supported kernel. The Ubuntu 16.04 LTS installs 4.4.0 on my machine. You may like to try compiling a newer custom kernel. See https://www.kernel.org/ for list of supported kernels. Good luck, Tobin.
After a cold reboot, the NM is not detecting the WIFI. Machine is not able to recover from this. I also restarted network manager and reloaded the driver but didn't fix the issue.
Tried: sudo rmmod -f ath5k (got a msg -- disconnected - you are offline) sudo rfkill unblock all sudo modprobe ath5k (Nothing happened)
When i check the /etc/modprobe.d/blacklist-ath_pci.conf, I see the following -
#For some Atheros 5K RF MACs, the madwifi driver loads but fails to #correctly initialize the hardware, leaving it in a state from which ath5k #cannot recover. To prevent this condition, stop madwifi from loading by #default. Use Jockey to select one driver or the other. (Ubuntu #315056, #323830) blacklist ath_pci
There are some bugs reported in the past but I don't come across anything that was reported in the latest kernel which is similar. Not sure if this is a bug still lurking around but I found someone reporting a similar problem here - https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1569590.
Any guidance is much appreciated.
Thanks, Vasu
