Hello, few days ago i bought T2U Nano i have an old laptop with only 2.4ghz wifi adapter and wanted to use my 5ghz wifi.

So everything connecte ok but my internet speed is 120mbps max (i got 250mbps internet).

I tried installing different drivers and so on but nothing.

Just as i was about to quit and use it as it is i decided to try and run it on linux and...

My speed went up to 210-230mbps. 

Still both me and my girlfried use this laptop and she is not comfortable with Linux. Are there any realtek drivers i can use (tried a few but same thing) or anything i can do to make adapter work on Windows 10 as it should?

Thank you!
