TP-Link BE9300 WiFi 7 card cant connect to 6 GHz network on Archer BE800

Hey everyone! I would appreciate some help. I just installed a Wi-Fi 7 card from TP-Link, and I already have a router set up with two separate networks: a single network that automatically routes 2.4 GHz to 5 GHz, and another network that's exclusively 6 GHz. I'm on a Windows 11 desktop with this Wi-Fi 7 card, and it's not allowing me to connect despite me typing in the right password. It's saying, "Can't connect to this network." Any advice is appreciated. Thank you!
