Hello,

I'm having issues with my Archer T3U - the one that apparently it's know at least since August (that's the first topic which was raised on this issue). It's simple: it hardly connects to the 5Ghz, it has no issues with the 2.4. IF (a very BIG if) connects it functions alright. Otherwise, I keep getting the "can't conenct to the network". 

I'm using windows 11. Tell me what other details are needed. 

Please don't give me the usual "did you update the driver?". Yes, I did, I got it from here https://www.tp-link.com/ro/support/download/archer-t3u/

I've also tried all the channels 

I've also changed the wireless mode to IEEE 802.11ac

Is there really no solution since this issue was first reported months ago? I'm giving this adapter 2 days top, otherwise I'm returning it and getting one from a new manufacturer. 

Thank you.
