Hi,
Just buy TP-LINK AC1300 Archer T4U and have problems with finding 5G. Want to use with my PC Win 10.
2.4 works normaly.
I try 5G on other computers, for my mac air, work normaly, but PC cant find.
I checked "Computer Management" TP-Link "Advanced" settings.
Prederred Bard: 5G first.
Wireless mode: auto
Try command prompt my PC settings, accept 5G.
So, how to solve? Maybe need to swich to 5G?

Hi, Are you able to change the wireless channel of the 5ghz on the main router, like channel 36 or 48 to see whether the PC is able to detect the 5ghz band this time?
Wait for your reply.

Hi, you could install a WiFi analyzer on the PC.
But there might be another problem the wireless channel of Samsung Mobile Hotspot could not be changed.
In the meanwhile, I do see some similar issues with Samsung Hotspot:
If your adapter T4U is also an EU version, it does not support band 4/channel 149 either.
Best regards.

Hi, did you check the region code on T4U?
The current EU version devices from TP-Link did not support band 4 due to CE certification, not just Archer T4U.
As for the Mac, I see its country code is LT, instead of the general EU version. It seems adapted better to the local Wi-Fi regulation.
Thank you very much.
Best regards.

Hi, welcome to the community.
Is the 5Ghz of your main router working on band 4-channel 149 as well?
Wait for your reply.
