Problem with iwlwifi

[AndyM48]

I have a problem with iwlwifi in that it is hard blocked according to rfkill after resuming from mem suspend.

There is an error logged from time to time:

kernel: iwlwifi 0000:00:14.3: RFIm is deactivated, reason = 4

I don't know what this means or if it could affect the issue? Something to do with Radio Frequency I think?

Welcome.
RFIm, (RF Interference Mitigation) is a chip feature that manages interference between radio signals. The output message is just saying that this feature is not active for some reason. The error code 4 is an intel code for which I can't find an explanation quickly, but it's not fatal since wifi can work normally despite this error message. Thus, if the wifi works, it's really not a problem. Is the wifi working?

Only, as I mentioned, there is a problem with iwlwifi in that it is hard blocked according to rfkill after resuming from mem suspend. Apart from that wifi works fine.

It does not sound like the error message is related?

I find that turning of power save feature can cure the problem your facing.
it's not iwlwifi but with he power save function.

cat /etc/NetworkManager/conf.d/*.conf
Unless it has been previously changed, it should read:

[connection]
wifi.powersave = 3
In this context, 3 indicates that the Network Manager will use power saving. Let's change it to 2, indicating that the system will not use power saving. From the terminal:

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
sudo systemctl restart NetworkManager.service

You can always reverse it if it does not work.

Already set to wifi.powersave = 2
Thanks for the suggestion.
