@alelelelee Good day, 

Please disable the built-in or other wireless adapters on your computer if there is any. 

Here is a public driver for Archer T3U Plus, please give it a try：

If still the same problem, can you help attach the photo of Error again?  Does this issue happen on 2.4 Ghz or 5Ghz Wi-Fi? 

Do you need to manually reconnect to wifi and it will work again?  Please help provide some information of the driver date& motherboad, thank you.

Now not same the problem, now lose the signal(?), connectivity every 15-20 sec. Dont need manually reconnect, because the signal is on max, but if i test the speed i see its drop randomly to 0 and few moments later it accelerates slowly back then drop to 0 again. On 2.4Ghz because this device does not see the 5G, but sometimes it does, randomly(dont know why). Now i just reinstall the driver from the CD because i delete the current and use another adapter.
