I'm receiving slow speeds on my Archer TX20U Nano AX1800 adapter (recently purchased a day ago). Not sure what's wrong or if I'm missing something in regard to settings etc, but kind of expected to be a plug n play and realistically have speed results better than what I'm getting in comparison to my other WiFi adapters via lappy and desktop.

What I've tried ...

• Installed latest drivers
• Connecting USB WiFi device to different USB ports on both laptop (USB 2.0) and desktop (USB 2.0 and USB 5Gbps & 10Gbps)
• Testing on laptop was 2 metres from the router
• Testing on desktop is about 10 metres from router
• Unchecked 'Allow the computer to turn off this device to save power' option via Power Management

Any help will be much appreciated, thanks in advance.
