Unable to discover 5GHz connection using TP-Link Archer T2U AC600
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?
