Archer T4U most of the times does not connect to 5 GHz
I got Archer T4U v3 to connect to wifi since my motherboard does not have wifi card. The router is pretty close too and I can see good signal strength on both 2.4 and 5 GHz.
When I tr to connect it to 5 GHz - sometimes it connects but most of the time it doesn't. I think there is a pattern here too - Whenever I start my PC after shut down, it doesn't connect to 5 GHz. I use 2.4 Ghz for like 30min (which connects all the time) and then when I try to connect to 5 GHz, 60% of the times it works.
Please help me out. I don't have the option to use LAN cable and really depend on 5 GHz connection for work.
Thanks.
