My PS5 is wired (works great), but my PS Portal lags like crazy over 5 GHz Wi-Fi just 10 feet from the router. The picture goes blurry, and it constantly disconnects. The router is on Auto Channel and 80 MHz. I suspect the 5 GHz signal looks “good” but is actually messy and unstable due to interference.
First thing: make sure the PS5 is actually using LAN. I know you said it’s hardwired, but on PS5 you can have the cable plugged in and still be connected over WiFi if the settings weren’t changed. Go into network settings and confirm the active connection is wired LAN. Portal streaming is local network sensitive. If the PS5 is secretly on WiFi, you’re basically doing WiFi → router → WiFi, which can be a mess.
@frozen_shift_X Yeah, I’ll double-check that again. I’m pretty sure it’s wired, but I know the PS5 can be weird about that. When I test directly on the PS5 I get around 700–900 Mbps down and 400–500 up. Through the Portal troubleshooting menu it shows much worse numbers, sometimes like 5–10 Mbps down and tiny upload, even though signal strength says good.
If the PS5 wired test is that good but the Portal diagnostic looks terrible, I’d stop focusing on your ISP speed. Portal doesn’t need gigabit internet. It needs stable local network performance between PS5 → router → Portal. You can have 900 Mbps internet and still have trash WiFi airtime. Since you’re close to the router, check the 5 GHz channel situation. Apartment? Townhouse? Lots of neighbors? DFS channel? 80 MHz channel width? All of that can matter. I’d run NetSpot or another WiFi analyzer where you actually sit with the Portal. Check the 5 GHz channel graph, nearby networks, signal level, and whether your router is sitting on a crowded or DFS channel. If you’re on Android, NetSpot can also give channel recommendations, which is useful before changing router settings.
@Dilemma_Fixer I’m in an apartment building with tons of neighbor networks.
@Dilemma_Fixer Yeah, I checked, and the situation with the channels actually does raise some questions.
