Hello everyone! I'm experiencing significant internet speed issues with my PC. While other devices nearby are hitting speeds of around 250 Mbps down and 60 Mbps up, my PC is struggling to keep up, managing only about 20 Mbps down and 10 Mbps up. I'm currently using a wireless connection with a B650M motherboard that has built-in wireless. Unfortunately, I can't switch to a wired connection. I've tried numerous solutions including resetting network adapters, following commands to fix network issues, relocating the PC, rebooting the internet, and even reinstalling the drivers fresh. At one point, after moving the PC, I did manage to get stable speeds of 150 Mbps down and 50 Mbps up, but that was short-lived, and now the connection is worse than before. I'd really appreciate any guidance or tips you might have. Thanks! Just to add, the antennas are attached and positioned to face outward from the wall, toward the router. My internet setup is T-Mobile 5G home internet without an external router, and all other devices are functioning well. Although reinstalling the WiFi drivers has provided some temporary improvement, I find that the performance tends to drop again after restarting or after a little while.

Have you considered testing your connection by hotspotting from a 5G phone right next to the PC? Also, make sure you're connecting to the right frequency—are you on 5GHz or 2.4GHz? Sometimes it can switch between them. What app are you using to test your network speed?
Just to confirm, you've got the WiFi antennas securely attached, right?
Yes, my bad for not stating that initially!
If your antennas are directly connected to the back of the PC, they might be getting blocked by an RF shield. They make short cable antennas, so you can position them further away from the PC, even on top of it for better reception!
When I tested using my phone, I got roughly 200 Mbps down and 15 Mbps up. I'm using Speedtest.net for my connection tests, but I'm not really experienced with other network testing tools. I think my PC might be switching between 5GHz and 2.4GHz.
