Public bug reported:
Good day, my wifi stopped connecting to WPA2 Enterprise, right after
I've upgraded BIOS. The BIOS upgrade could cause this; I was also
playing with bluetooth headphones which could be connected.
The Wifi works properly in Windows 10, so I assume it's not a hardware
bug.
The interesting line in dmesg:
[ 133.921138] iwlwifi 0000:04:00.0: Microcode SW error detected.
Restarting 0x92000000.
I thought the microcode file could be corrupted, so I've tried apt
install --reinstall linux-firmware and reboot, but that didn't work.
dmidecode -s bios-version says N1EET81W (1.54 ); dmesg says LENOVO
20EN0005MS/20EN0005MS, BIOS N1EET81W (1.54 ) 11/14/2018
Thank you for providing any pointers...
