I have a T2U AC600 Wireless Dual Band USB Adapter but I am unable to discover 5GHz connections though they are discoverable by my mobile phone and another laptop with dual-band card.

 

I have installed a  Windows 10 OS with the latest drivers for the adapter(https://static.tp-link.com/2017/201711/20171116/Archer%20T2U_EU_US_170724_Wins.zip)

 

My wireless router is a dual-band router and 5G band is supported at channel 39. I have already tried to change the channel configuration for T2U adapter to other channels but no respite.  I believe that channel selection should be auto for band 5 rather than multiple channel selections.
 

Is the device faulty or some other configuration is required?

Hi,

 

What's the version of your T2U adapter? EU or US version?

 

What's the hardware version of the T2U?

The 5G band include band 1-band 4, have you tried change the router's channel to the channel in band 1, like the channel 36, 40, 44 to have a check? If not, you can have a test.

The hardware version is TE7T2U.  I have manually set the router's channel to 48 and now 5Ghz connection can be discovered. 

But I believe that channel selection should be auto for band 5 rather than multiple channel selections in the adapter properties.
