Network manager issue

[anonymousb.i.g.986]

Wifi on Kali 2020.4 and 2021.1 continuously disconnects; the only temporary solution to delete the ESSID in network manager. Hardware works as there are no issues on Windows, as does the wireless card itself. The interface shows connection and network lock by vpn does not activate. So I'm deducing it is a gateway issue. Any help on a more permanent solution would be greatly appreciated.

I also have to restart NetworkManager using:

systemctl restart NetworkManager

I have to the best of my knowledge, installed any and all missing firmware into /lib/firmware.

I have deleted gateways, with some success, it returns though. I tried to reinstall fresh and also network manager.

This is incredibly frustrating.
