Windows 10 X64 

OS Build 19042.685 ( all windows updates are completed as of todays date)

I have an issue with slow speeds and compatibility.

I have purchased this adapter and could not get it to install. I have seen threads on the forums to try different drivers to resolve this issue, Which i have done.

The latest driver on the TP Link site will make the adapter constantly refresh in device manager and i cannot get it to be stable enough to make a wireless connection. If you watch the device manager window you can literally see the device appear then disappear constantly.

This driver above does exactly the same.

This driver above does exactly the same.

The driver version 1030.22.202.2018 - works fine but the speeds are poor. it is stable and does function but i cannot get any speeds above 270Mbps and my phone will do 550 Mpbs in exactly the same spot.

I have it connected to a usb3 port and tried with a USB 2 port.

2.4 GHZ works fine.

is a new driver available or can anyone help please ? or do i need to return the adapter

I am currently connected to a TP LInk AX3000 router.
