I recently built a new PC and set it up on the second floor, while my router is on the first floor, which I suspect might be causing my Wi-Fi issues. Here's what I've tried so far:
- Uninstalled and reinstalled the correct drivers multiple times.
- Tested both 5GHz and 6GHz connections.
- Ensured the stock antennas are correctly positioned.
- Adjusted various settings in the device manager.
Despite all these efforts, my Wi-Fi speeds are awful, averaging around 5 Mbps, with a peak of about 30 Mbps. In comparison, my phone, located in the same room, consistently gets around 130 Mbps. I'm wondering if I should invest in a new PCIe Wi-Fi card or if it would be better to replace the stock antennas with higher-quality ones that can be positioned on my desk, away from any potential sources of interference.

Don't forget about the orientation of the antennas! Sometimes just tilting them or changing their position can help a lot. If that doesn’t work, then considering a dedicated Wi-Fi card is definitely a good move.
I’d recommend swapping out the stock antennas for some that can be positioned on your desk. Getting them higher up and away from any obstructions can make a big difference in signal quality.
It sounds like your PC's location is a big factor. Have you tried checking the speed on your phone again? You mentioned it gets about 130 Mbps; that’s a solid benchmark! Maybe a new Wi-Fi card could help, but I'd try the antennas first since they can be a cheaper solution.

Totally agree! I've seen a major boost by just relocating my antennas. I used to get around 50Mbps and moving them up made it shoot up to around 400Mbps stable.
