Model: Archer T3U  
Hardware Version:
Firmware Version:

Recently bought an Archer T3U plus wifi adapter, and when I first connected it I got 130 Mbs speed. The problem is as soon as I reboot my PC I go down to 30 mbs until I disconnect and reconnect the usb adapter, then I go back to 130Mbs.  I have the "Archer T3U Plus(UN)_V1_win10&win11_191204" drivers installed.

 

Anyone knows what cause that?

Hi, welcome to the community.

I am not sure what might be the problem but there are some suggestions for your reference:

1. I think the computer is connected to the 5ghz of the main router, if possible, please change the 5Ghz of the main router to channel 48 and the channel width- 80mhz.

2. Please also install the driver here:

Thank you very much.

Best regards.
