I have laptop and desktop running win10 and win11. Purcahsed Archer T2U and T2U Nano for each device. If I download huge amount of data such as games on 5ghz, the wifi randomly disconnects even though the adaptor is connected to the system and the light is blinking. Though it works fine on 2.4ghz. It happens on both my device with both the adaptors. I tried switching the adaptors but still the same. At first I used the driver that came with the disk. It was giving me problem. So i uninstalled and installed new drivers from tp link website of the respective adaptors but still getting the issue. Tried changing the wifi channel but still the same issue. Can anyone help me?

so summarising everything, if i download huge amount of data, 5ghz wifi disconnects. But if i do the same thing on 2.4ghz, it works fine.
