Windows 10: HP OMEN with Realtek RTL8822BE 802.11ac PCIe Adapter unable to connect to 5G suddenly?

Hey, I have an HP OMEN with a Realtek wifi adapter, which used to be able to connect to 5Ghz with no problems. Recently, I've found my wifi is not as fast as it used to be, and when I checked it, it was connected on the 2.4Ghz. I attempted to connect to the 5Ghz, but it just says 'Can't Connect to this Network.'The only recent event that I think could have impacted the driver or the system is an update from my provider to the modem, or a failed Windows 11 update I tried. Help! lol
