Wireless game streaming is another reason to upgrade WiFi. I couldn’t stream anything from my wired desktop to my Steam Deck on WiFi from the ISP-supplied router. I just finished upgrading to a WiFi mesh network partly because of that… but I haven’t tested game streaming yet.

I expect it should do great, though. My Fire Stick used to occasionally buffer even with ~1.5GB/hr content, but I just tried a 1080p remux at 15GB/hr and it worked great.
