laptop iwlwifi suddenly not working

laptop iwlwifi suddenly not working

[jim.cromie]

while fumbling to pause grub during boot,
I think I managed to disable the wifi.

its affecting distro kernel, and my own

booting with iwlwifi.debug=0xff on command line
shows me

iwl_pcie_apm_init Init card's basic functions
reporting RF_KILL (radio disabled)

It is reading that from somewhere, but where ?

F12 has radio-beacon icon,
pressing it causes WM to show Airplane mode,
so that appears to be the rfr-kill switch
dmesg -w shows me bluetooth going on and off,
but no try to do so on iwlwifi
are there other rf-switches ?

I also tried reboot, F2 - (uefi bios) reset factory, reboot
that obviously didnt help

FWIW this laptop exhibits pcie correctable errors,
I have pci=noaer in my boot line to ignore it.  too long ?
iirc, it was on same pcie port
removing it doesnt help now,

Maybe there’s a hardware switch that toggles airplane mode? Might not be, since I’d think that would be kind of redundant if there’s a fn key dedicated to it, but I remember my previous laptops had a physical slider switch for airplane mode. Might be worth checking to see if your laptop has one and if it was accidentally toggled.

nope.  2 older laptops have that switch, but not this one.
One of the leds on the edge is a wifi indicator,
it turns on/off when I hit F12, they are in sync with WM-screen notifications

There is a bios update, but it requires windows to install, long gone
with dead hd.
Im trying to download a windows iso, I'll try sticking it on a Usb and
try booting it,
but Im not optimistic

I was able to do a BIOS upgrade just the other day: after booting
Windows installation USB enter repair mode and start command prompt.
In command prompt locate the exe file for BIOS upgrade and just run it.

So, to close this out, I'll report


I found fix on toms-hardware, from 2013, for another toshiba laptop.

pull the battery and plug-power, hit the power button, to attempt turn-on
reinstall battery, boot
thats it.

heres when it was broken

theres a lot of rfkill toggling going on there,
but oddly in working version too, just less (not the early reported one)
other diffs might be cuz i fiddled with systemd disable rfkill, which
didnt fix it

Note, this is some sort of super-factory-reset,
cuz plain old bios factory-reset didnt work (unless impossibly delayed)

Now to decide whether to keep the shiny new replacement,
this keyboard is getting a little crusty.
