Wifi connection slows down PC

[Xelus]

I have an Asus PCE-N15 in my desktop. This card when connected to the wifi automatically slows down the PC and slows it down to the point of unusable. On my laptop however, it works perfectly fine. I have uninstalled and re-installed the drivers for this and it still doesn't work.

But when I connect my ethernet cable, it works perfectly fine again.

Please help. THANKS

Ethernet will ALWAYS out perform WiFi.

 

Is the laptop in the same area as the Desktop?

No. But I have tested it in the same area. I prefer ethernet but my house always have people walking around so people easily trip on it. So I have to end up with the wifi.
