I just wrote an addendum that crossed in the mail with your msg. This
kernel with these drivers worked last week. I just noticed that I
didn't have an /etc/wpa_supplicant so added the same trivial one I have
on my current machine
# The below line not be changed otherwise we refuse to work
ctrl_interface=/var/run/wpa_supplicant
network={
key_mgmt=NONE
priority=-9999999
}
Unplugging the wired enet didn't help (I waited a minute).
The trivial /etc/wpa_supplicant/wpa_supplicant.conf had no effect.
It looks strange. dmesg shows the iwlwifi driver responding,
recognizing the card, and loading the microcode using iwlmvm (see above)
What does L1 disabled mean? I googled and found other getting that msg
but no explanation of what it means.
thanks,
allan
