Hi benny,

Could you please tell me the version of your adapter?

And also could you please send me the screenshot about the device management page? Do you need to install it in the Win 7 or Win10?

Best Regards!

Hi

My adapter is 

AC600 MINI WIRELESS USB ADAPTER ARCHER T2U

(EU) VER.3.0

S/N 2195931004792

P/N 0152502259

2A

I don't know what you mean for the device management page but I think it could be like that:https://www.tp-link.com/it/support/download/archer-t2u/
I'd like to use it both on Windows 7 and Windows 10.

Best regards

Benny
