Hi,

There shouldn't be a need to change any settings within the Properties. Your operating system should show nearby 5 GHz wireless networks if there are any.

You could check with a free Wi-Fi Scanner or Wi-Fi Analyzer software to determine if your T6E does indeed not see any 5 GHz networks.
 

  @Mcdonalds321 I'm not familure with Win11.  However, I might have just had a similure problem and possable solution to your problem...

Find Win11 verion of the control panel, then the divice manager. Find your router. Right click on it and then properties, Advanced tab, Select Wireless mode. Select IEEE 802.11ac (ac is the 5 GHz band).

This is what I do in Win7Pro64b.

Good luck...
