Don’t forget to set your regulatory domain! Twice now I’ve gotten bit by this not well documented setting. Linux does not set this for you. It doesn’t assume where you’re in the world and it wants to make your wifi comply with every law for every country so your regulatory domain is never set. This means performance suffers, you might see lag spikes, dropped frames, network jitter and other annoying things. This stands out when streaming with sunshine and moonlight which requires there to be no frame drops.

For the steamdeck following this arch wiki article worked for me.

https://wiki.archlinux.org/title/Network_configuration/Wireless#Respecting_the_regulatory_domain

Simply editing the conf file and Un commenting your country fixed my lag spikes and dropped frames when using moonlight.

This happened twice now, once on the steamdeck and then another time on a different Linux distro, I think it was Opensuse? Maybe arch as well?

However, don’t be a dick. This setting means the wifi chip will act in accordance with what the country you’re in allows by law. So if you travel from the US to say Mexico, the laws will be different and radio frequencies and settings your wifi chip use in the US may not be allowed in Mexico and you may violate shit.

I’m not responsible for that and neither is the arch wiki, that’s on you.

But if you don’t travel with your device from country to country frequently, this setting may be just what you need to get a consistent wifi connection!
