Hi,   Recently I upgraded /sudo apt-upgrade/ my armbian and my wlan is now gone /it worked perfectly before/. Looks like xradio module is missing from the new kernel? I am trying to download driver from http://linux-sunxi.org/Wifi, especially from http://kaiser-edv.de/tmp/lGtv38/patch-add-support-xr819.tar.gz .... but the site is not working.
