Dear Forum,

I have an Archer AX72 router which works properly, every mobile and notebook can connect to it and the bandwidth is fine. Except my pc, where I had to buy an adapter to be able to use wifi, and I've chosen Archer T4U Plus. It often disconnects, but when it succeeds, the bandwidth is super low, like the image below:

Tried reinstalling drivers, tried every usb port of my pc, nothing worked in the long run. Can anyone help?

Thanks,

József
