Hello everyone, I have a weird issue with my Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter. When trying to connect to a wireless network in Kali, I can only see 5ghz networks, no 2.4ghz. Airodump-ng is able to see both bands along with other scanning scripts. Problem only applies to when selecting a network. No errors in dmesg.
I have the latest version of Oracle VirtualbBox, Kali, NIC firmware and the device driver in Kali.
It seems when I lookup this issue the only things that come up is problems for not detecting 5ghz.
Any help would be greatly appreciated.

I have re-installed Kali and able to see all networks (both bands) but now have a new problem.
The only way I am able to see both bands is if edit the NetworkManager.conf to have "managed=true".
However, the problem now is that the USB card will disconnect it self from Kali (Windows will make the connect sound) and the USB will still show up in Kali but will not be functional. Monitor mode wont work, cant detect any networks. Unplugging the device and repluuging it back in will fix the problem for about 30 seconds and it will do it again.
Genuinely confused.
Any help appreciated.
