I don’t remember doing anything of note on friday but my laptop’s wireless adapter stopped working and I’m not sure why. The wifi works when I plug in my wifi adapter, but it’s slow and occasionally I have to unplug and replug the adapter when my connection gets shut off.
How do I get my laptop’s wifi connection working again?
What’s your hardware info?
Can use this to get it:
inxi -FAZ --no-host | eos-sendlog
Did you do any troubleshooting? https://wiki.archlinux.org/title/Network_configuration/Wireless
From what I see, everything should be working fine. Could you provide some specific errors? Can see the wiki page on how to find any wifi related issues.
You could try doing a system update, maybe newer version of kernel helps.
Either with eos-update --yay or yay.
I tried a system update but it didn’t seem to work. When I tried journalctl -f and viewed the output, I got this:

After consulting the wiki page you linked, it looks like the problem is to do with power saving, but I’m not sure how to find the power management options for my card. I already went into BIOS and didn’t see any options relating to Wi-Fi card power management there.
I checked the /etc/modprobe.d/ folder and there’s no iwlwifi.conf file there. should I make a file in that folder to edit, and how do I do so?
Yes you have to create that file and add the options you need or want in it.
/etc/modprobe.d/iwlwifi.conf
Created a new file and edited it with power_save=0. Restarted the computer and it seems to work for now. I’ll let you know if anything else goes wrong, but for now I think this is the solution.
