[SOLVED] WiFi suddenly not working after suspend

I've been running arch for a few months now and everything has been fine so far. However, recently, I have been experiencing the issue of my WiFi not being able to reconnect after waking up my laptop from suspend (this has never been an issue until now).

This issue started occurring after I booted into Windows (I am running a dual boot) for the first time after a long while. I don't really understand why that would cause any issues and perhaps the timeline is just a coincidence, but I thought it was worth mentioning that this is when it started happening. Could've also been a system update, I don't remember if I did one on the same day.

Also, when this happens, I can't figure out a way to fix it other than just restarting my laptop. Restarting the NetworkManager service does not fix the issue, I've found that only a full reboot does, which is pretty annoying.

I've tried searching around for solutions, but I haven't really found anything that worked. I tried the suggestion on the wiki, which is to disable WiFi power saving, which did nothing for me.

After this happens, I can see in the logs of NetworkManager and wpa_supplicant that something has gone wrong. The logs don't look the same every time, but here's two examples of the logs from separate times of the issue occurring.

Example 1:

Re: [SOLVED] WiFi suddenly not working after suspend

Seem to be having the same problem anytime I disconnect my network connection. Running "sudo systemctl restart systemd-resolved" seems to cure the problem till I disconnect or wake from suspend. Just started happening after the last update.

Re: [SOLVED] WiFi suddenly not working after suspend

Someone on Reddit gave me the tip of removing the device with

echo 1 > /sys/bus/pci/devices/0000\:03\:00.0/remove

and then triggering a bus rescan with

echo 1 > /sys/bus/pci/rescan

For me, this completely fixes the issue in the current session. The issue only comes back after a reboot. Thus, a simple fix is just to run these two commands automatically on startup. I'll hold out to see if I can find a "more proper" fix, otherwise, I'll just do it like this. Give it a try to see if it works for you as well!

Link to the Reddit thread for more information.

Re: [SOLVED] WiFi suddenly not working after suspend

Sorry, I should have posted my WiFi chip here as well. It's an Intel chip. lspci output:

Re: [SOLVED] WiFi suddenly not working after suspend

This is typically power saving related, https://wiki.archlinux.org/title/Power_ … _(iwlwifi) but you'd want to *disable* the power saving stuff to test this.
Are there any dmesg errors (typically the firmware crashes, NM and wpa_supplicant are irrelevant itr)

Re: [SOLVED] WiFi suddenly not working after suspend

Yes, there is crashing. Sorry, I included this in the Reddit post I linked, but I hadn't figured this out yet when I made the post here. But I'll post the logs here. After waking up, I just get the following, which then repeats (as you can see in the bottom) and then I get the same output many times.
I'll try to change the powersave setting for iwlwifi and see if that results in anything.

edit: I looked at the current parameters for iwlwifi, seems like most of the powersaving stuff is turned off already?

Re: [SOLVED] WiFi suddenly not working after suspend

Having the same problem here (Manjaro and Omen 15) answer on #3 seems to work right now, at least I don't have to restart the notebook.

Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a) lspci result for my card

Re: [SOLVED] WiFi suddenly not working after suspend

So to anyone looking this up, I managed to find a fix to this issue in some other thread that I can't find anymore. Nonetheless, the solution worked, so I'll post it here.
Create the file 

/etc/modprobe.d/iwl.conf

and add the following lines to it:

options iwlwifi swcrypto=0
options iwlwifi bt_coex_active=0
options iwlwifi power_save=0
options iwlwifi uapsd_disable=1
options iwlmvm power_scheme=1

The thread also mentions the following options

options cfg80211 cfg80211_disable_40mhz_24ghz=Y
options iwlwifi 11n_disable=1

However, it was also said that these will impact your network speed, so try seeing if it works without these options. In my case, it did.
