firmware: failed to load iwlwifi-8000C-25/26.ucode (-2) [duplicate]

Question

Hello I have a Lenovo T460 and just installed Debian 8.7.1 but my wifi doesnt work. I'd read that I need kernel 4.1+ to have working the wifi and just updated to 4.9.0 but when I restart the computer with that kernel I'm getting two errors

iwlwifi 0000:04:00.0: firmware: failed to load iwlwifi-8000C-26.ucode (-2)
iwlwifi 0000:04:00.0: firmware: failed to load iwlwifi-8000C-25.ucode (-2)

I had other more errors but I've been clearing but those last I can't find a way to fix. Does anyone know what can I do?

thank you in advance for any help

In my case this was happening after Linux was suspended and then woke up. What helped (except for a reboot, of course) was removing the kernel modules, reinserting them and restarting the network (Fedora):

rmmod iwlmvm rmmod iwlwifi modprobe iwlmvm modprobe iwlwifi /etc/init.d/network restart
