PCI WiFi adapter malfunctions during gameplay
PCI WiFi adapter malfunctions during gameplay
My wireless adapter (ASUS PCE-AC51) fails only when I start playing games, not during browsing. I’ve downloaded games through Steam all night without any internet drops and can browse normally, but once I launch a game it malfunctions. I’ve tested the same card on three different computers and got the same issue. Updated drivers didn’t help. It doesn’t affect Steam either—I used various game clients. When I enter a game, after about three minutes the internet drops completely; initially data comes through but no output is sent. I can see other players moving and being killed, yet I have no control over it. Resetting the Wi-Fi adapter fixes the problem after another three minutes, but then it’s gone again. If anyone has any advice, you’d be the star of the show!
The concept suggests that current computers likely lack sufficient PCIe lanes. When a game demands all 16 PCIe lanes, there may not be enough capacity left for other devices like a Wi-Fi card. This idea depends significantly on the system's CPU and installed components.
I think the problem might be related to temperature. Try relocating the WiFi card away from your GPU. Test with the case removed. If it works when open but not closed, add more fans. Observe what happens if the WiFi signal disappears. When you press ALT+TAB in-game, see how Windows displays the connection status—connected, disconnected, or completely offline. If it's connected, attempt a ping to your router. If disconnected, try reconnecting. If it's offline, it could point to temperature issues or faulty hardware. Regarding the PCIe lanes, ensure your GPU is connected to the correct top slot—it shouldn't share lanes with other devices. If it's in another slot, lane contention might affect performance but not cause the card to drop.
