Archer T3U can't connect to 5GHz
I've been using this for around 11 months now and it has been great. However, recently, it started malfunctioning. I encounter the same problem as the post here (https://community.tp-link.com/en/home/forum/topic/217836). Basically, whenever I launch my computer and it auto-connects to my 5 Ghz internet, it just stops working. I have to plug it out then plug it in again and connect to the 2.4 Ghz in order for it to work. Before restarting my PC, I clicked on "forget" on the 5 Ghz and it works perfectly fine with the 2.4 Ghz. Whenever I do the network diagnostics, it says something about "a problem with the network adapter driver". My 5 Ghz internet works for all of my other devices, just not with my Archer T3U. It used to work, but now it doesn't. I'm currently connected to my 2.4 Ghz and if I try to connect to my 5 Ghz, the T3U will crash and stop working and I have to unplug and re-plug it in order for it to work. How do I fix this?
