I am running Tumbleweed on a Thinkpad T440. It was previously running great for several weeks. Last night I installed updates one of which I am pretty sure included a a kernel update. And upon reboot now the Intel 7260 wireless card is just completely gone. I still see it in lspci, but ifconfig -a shows nothing. iwconfig says there are no wireless devices.
uname -r says:
Any ideas of what I can do to troubleshoot? Any help is appreciated.
I found this in dmesg:
6.225782] iwlwifi 0000:03:00.0: irq 46 for MSI/MSI-X
6.226393] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7260-10.ucode failed with error -2
6.226408] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7260-9.ucode failed with error -2
6.226410] iwlwifi 0000:03:00.0: request for firmware file ‘iwlwifi-7260-9.ucode’ failed.
6.226420] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7260-8.ucode failed with error -2
6.226422] iwlwifi 0000:03:00.0: request for firmware file ‘iwlwifi-7260-8.ucode’ failed.
6.226423] iwlwifi 0000:03:00.0: no suitable firmware found!
So I went here: http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware and downloaded the 7260 firmware and copied it into /lib/firmware and rebooted and poof it is all working again. No idea what happened. According to the intel site all the kernels after 3.14 should have this firmware baked in but it went away somehow. I am just glad I have my wireless back.
