your pc connects to wifi through a usb adapter, but speed tests show only about 3 mbps. real downloads average around 500 kbps, while mobile speeds are much higher—around 20 mbps on your phone. you’ve already tried the same adapter, so the issue might lie elsewhere. you’re considering the motherboard as a possible cause.
Where is your brother's signal coming from? It's possible something in the walls or ceiling is affecting the connection. Sometimes it's tricky to pinpoint exactly what's causing the issue. You might want to move your PC downstairs nearer to the router and see if performance improves. If it does, consider using a USB extension cable (if you don't already have one) and test the adapter in various locations to get the best signal.
As mentioned, if you haven’t already, consider using a USB extension since they’re inexpensive and might resolve signal issues in the specific area your PC occupies. The fact that the same adapter works less well when you’re nearer to the router hints at this. Have you tested your brother’s PC in the location you’re using? Are the USB ports on the back or front? A front port could interfere if the router is positioned behind it.
