Your PC experiences significant packet loss and high ping when connected to 2.4GHz Wi-Fi, but you'd like to switch to 5GHz only. You mentioned concerns about network configuration—your settings in Device Manager are correctly prioritizing 5GHz, yet the adapter still reverts to 2.4GHz after some time. Using Ethernet isn't an option, and splitting the network into separate 2.4 and 5GHz channels would interfere with other devices. On your Gigabyte X570SI Aorus Pro AX board running Windows 11, ensure the Wi-Fi adapter is properly set to exclusively use the 5GHz band and that the preference is enabled. If issues persist despite these settings, consider checking for firmware updates or consulting the manufacturer's support for further troubleshooting.

In Windows, launch Device Manager, locate your Wi-Fi adapter, and you'll usually see options for hardware settings that let you choose a specific frequency band, like 5 GHz. If that's unavailable, consider using additional software or driver controls, as there doesn't appear to be a direct method to force the system to prioritize one band over another.

I had already tried, but it keeps switching back to 2.4GHz.

You might contact your service to switch to separate 2.4GHz and 5GHz connections instead of a single one. It seems I didn’t understand your message clearly. Could you check if your router has an option to assign a 5GHz link based on your PC’s MAC address?

If the 5GHz signal appears weak, your adapter may not establish a connection. Additionally, certain wireless devices on access points might only detect a very faint client signal, triggering connection decisions once a specific threshold is reached. Weak signals result in poor connection quality. Have you checked the detected signal strength? Ensure the WiFi antenna is correctly connected to the I/O panel? Are there any barriers near the antenna?

The device works smoothly on 5GHz with strong speed and low latency. It tends to switch to 2.4GHz, which leads to problems. I can get it back online by disconnecting and reconnecting to Wi-Fi, but this process is frustrating and happens often. The antenna is just a meter away from the router and offers a clear line of sight.

Reduce the roaming behavior in adapter settings.

You seem to be in a tight spot, but a wired link would be better if you can.

Set up a separate network name just for the 5GHz band while keeping your existing one unchanged. This way, both networks will share the same channel and won’t interfere with each other unless your access point or router lacks support.
