Greetings! After much fussing, and many long hours and days on the forums here and bashing away on SSH, I am giving in and sharing my logs for tips, ideas, and hopefully, a solution.
RPi 2 (08) with Kernel 4.1.20-1-ARCH.
RuneAudio unable to connect to WLAN, regardless of whether ethernet is connected or not. In RuneaudioGI, SSID appears sporadically, sometimes without lock symbol or radio waves symbol. Sometimes, no other neighbouring SSIDs are found at all. It connected to the WLAN once a few days ago, but when I removed the ethernet cable, the WLAN dropped and never returned since.
Have already done a stash/pull from git (14.02.2018).
Using FritzBox router with WPA/WPA2, SSID always visible. SSID has no special characters. Other devices functioning properly with DHCP.
Static IP not working either. Resetting parameters with the "static/dhcp switch" trick has no effect.
Have worked on the netctl profile via SSH (SSID = 'Sheepies'), incl. adding an ssid_scan, and trying different proto settings.
Debug Log here:
Massively thankful for any suggestions you may have. Wishing you all a pleasant day.
