Hello all,
my wi-fi adapter isn’t finding any networks after (accidentally) starting the Anaconda installer and quitting it immediately. Another wi-fi adapter works fine.
I am using the Edimax EW-7811DAC USB adapter with a DKMS driver (rtl8812au). Until recently, it worked perfectly, rebuilding with kernel upgrades and everything.
However, then I accidentally started the Anaconda installer (I was actually trying to start the Anaconda Python distribution). I quit it as soon as the GUI came up, but since then, my adapter isn’t finding any networks. It stopped working the moment I started/quit Anaconda. The adapter shows up in Gnome status bar, everything seems normal, there are just no networks detected.
I’ve tried everything I could come up with: rebuilding via dkms, wiping the driver from the filesystem, redownloading and rebuilding, looking at all the logs I could think of (journald, dmesg), and I can find no indications that anything is out of the ordinary. I was hoping that upgrading from Fedora 30 to 31 would somehow fix the issue, but no luck.
Another USB wi-fi adapter using a different, non-DKMS driver works fine.
I would appreciate any pointers as to where to look next.
