WiFi adapter remains linked to 2.4 GHz exclusively on your desktop machine
I'm experiencing slower speeds with my USB Wi-Fi adapter compared to other setups. On some devices it reaches 5Gbps, but mine consistently stays at 2.4Gbps. I'm curious if others have encountered similar issues and any suggestions they might have. Same drivers, same router distance—just different results.
WiFi performance depends a lot on surroundings, which might mean it struggles to connect directly to the device. To understand this better, try using a free app on your phone that checks WiFi signals in a specific area. Sometimes settings or other factors can also play a role.
What router are you employing and does it automatically select the frequency band? Many auto-adjust systems shift from 5GHz to 2.4 when signal is below half strength. You might consider assigning each band its own SSID and ensuring you connect to the 5GHz network, then verify whether it provides sufficient speed compared to 2.4GHz.
Your USB Wi-Fi adapter functions on a different machine, which might indicate where your computer is situated. Check the distance between your computer and the router. You may need to refresh the driver or adjust settings in the network adapter's power management options.
Some adapters might force you to use only the 5GHz band, which means you’ll need to set up the adapter properly. From what you said, I think the 5GHz signal could be too weak on your desktop, so it might choose the more reliable 2.4GHz instead. Even if the distance to the router is similar or nearly the same, interference can still make your 5GHz connection unstable for your PC.
The final answer depends on whether it becomes an environmental concern. Possible options include using a repeater, mesh network, or relocating antennas or upgrading equipment (which might be feasible or not). Large special antennas are common. Changing antenna placement doesn’t always require moving the computer. Extension cables are designed for compatible connectors, especially if your motherboard supports Wi-Fi. If you use a USB dongle, you can relocate it with an appropriate cable. Things get tricky on a laptop but remain achievable. A repeater seems like the more practical choice.
I’ve completed most of what was discussed already. The laptop is placed in the same spot as my desktop. I’m still unsure if the issue lies with the adapter or the weak signal (the same problem occurred at my previous home with the router outside my room). I’d like to split the two frequency bands into separate SSIDs, but I’m currently renting and other residents—including my landlord—live with me. A photo is attached below to confirm the adapter supports 5GHz and defaults to 2.4GHz. I’ve also tried adjusting the settings to force 802.11ac, but no networks are now discoverable.
