5GHZ problem
5GHZ problem
You're experiencing varying performance issues with your new PC's PCIE wireless card. Initially, it connected smoothly at 5GHz with solid speeds, but now struggles to reach that frequency, dropping to only 10-20Mbps downloads. On your phone and MacBook Air, the connection remains stable at 5GHz or higher. The MacBook Air even achieves up to 300Mbps, while your old laptop caps at around 150Mbps. No recent driver changes or updates seem to have resolved the problem.
Determine the distance to your router, count the intervening walls by type, and identify nearby 5 GHz networks.
This seems to be a repeat of the problem my son experienced, which was resolved by using the running SG TCP Optimizer. It appears to have fixed his internet connection, though it isn't explicitly confirmed for Windows 10. I checked the download page at speedguide.net and saw similar results. Could a recent Windows update be contributing to this issue? If it does, you might be among the second person in the networking forum affected.
I will try this, and see. Tried didint help sadly thanks for the advice tho Computer is right under the router there is a tree wall and drywall its really thin can hear everything thats happening above, only on 5ghz network and 1 2.4ghz, no others in the area i live. Like i said phone, macbook, shitty school laptop all work from the same spot. I also have full bars.
Have you considered rearranging the cables and antennas to reduce interference? If the small antennas are on the back of the motherboard, it can be challenging to prevent wires and the case from obstructing the signal. Try shifting the PC around the room slightly—just a few feet, adjusting the orientation of the case might help. Sometimes external factors play a role too, like someone moving items above or near the router during its optimal performance period, which could disrupt the signal.
I've adjusted the antennas and the PC a bit, but I don't notice any issues because the network is fully active and it works perfectly on other devices. Maybe a new Wi-Fi adapter would help.
I can raise my PC slightly while placing my phone beneath it, and the internet remains stable, as the router stays within about 2 meters of me.
