I Updated few days ago my router to the beta 2 of 18.06 and the wireless simply stopped working.
Reverted to 17.01.5 but the wireless is still not working.
Tried the original firmware and the wireless simply works fine.
Tried to reset in every way, to flash even 15.05 but on Openwrt it doesn't start the wifi.
lsmod show that ath9k is correctly loaded.
No errors in dmesg.
lspci show the wifi device just fine
00:00.0 PCI bridge: Broadcom Limited Device 6328
01:00.0 Ethernet controller: Qualcomm Atheros AR5008 Wireless Network Adapter (rev 01)
Any ideas?
It worked just fine for years till yesterday.
