Model: Archer TBE400UH  
Hardware Version: V1
Firmware Version: 5102.24.126.2

Hi,

I was under the impression that this was a triband usb adapter and even in the summary of the driver it connects to only two bands at a time. I've set all my preferences to the 6Ghz band and in MLO it connects to 2.4Ghz+5Ghz or it just connects to the 6Ghz band alone. I know the 24h2 is the base to work from so I'm going to install that and see if that works. Yet even the current beta driver only shows 2 bands at the same time are possible.

The second problem is is that the outcome from powershell:
 

PS C:\Users\x> Get-NetConnectionProfile

Name                     : Archer TBE400UH
InterfaceAlias           : Archer TBE400UH
InterfaceIndex           : 39
NetworkCategory          : Private
DomainAuthenticationKind : None
IPv4Connectivity         : Internet
IPv6Connectivity         : NoTraffic

Name should have the correct SSID name and moreover in regedit I can't distinguish the 4 networks I have in my network list as it doesn't have the BSSID linked nor the GUID linked, i.e they are not the same as in:

PS C:\Users\x> netsh wlan show interfaces

nor in regedit where everything has Archer TBE400UH as name.

Which makes Windows revert to Public profile and kicks my local network offline during backups.

I'm also disappointed since I have the Deco BE85 Mesh Network and it feels like using the 5Ghz+6Ghz would be better. I'm also a bit disappointed I got v1. Which is probably the one with the most problems and also the one with the least features that can be fixed. However if it doesn't gain true triband soon I want my money back.

Thanks in Advance!
