I’ve had a weird issue with Steam lately.
Whenever I go to download a game on my pc, it will download fine, but I will lose internet for everything else on my network until the download is complete or I stop the download.
At first I thought this might be an issue with my ISP, but this doesn’t happen when downloading a game from my Steamdeck.
Anyone have any fixes for this?

Sounds like steam is saturating your connection, as the other user said, limit your download speed to somewhere below your connection speed.
The steamdeck may be fine because it had a slower wifi connection.
