I’ve tried F31 in Silverblue here too, and the wireless is still broken on an X230 (Intel Centrino Advanced-N 6205 rev 04), T460s (Intel 8260 rev 3a), and even a wifi USB stick (Edimax EW-7811Un / Realtek RTL8188CUS).
iwd package is installed on F31 alpha but not F30, I guess the issue is with Fedora switching to
(The problem doesn’t seem to be with https://bugzilla.redhat.com/show_bug.cgi?id=1733369 as the
linux-firmware mismatch with the kernel breaking Intel wireless, as the
linux-firmware package is up to date with the fix in the issue and F31 has problems with the Realtek USB stick too. I did completely power down and power back up as well, BTW.)
The only bug I see on rhbz related to iwd (besides one about updating versions) is https://bugzilla.redhat.com/show_bug.cgi?id=1743585
Meanwhile, in addition to wireless problems, seems to be toolbox completely broken on F31. It cannot download containers. (I have an ethernet cable plugged in to get network access… so it’s not that.)
