No internet after recent realtek driver changes

Hi. After previous realtek removing from system I stop having interent connection after 1-2min after system boots. But when I log in with:
Kernel Linux 5.14.0-0.bpo.2-amd64 x86_64 from Advanced booting options,
everything is fine.
But on Default PArrotOS I have no internet after few minutes.
I dont know if this is a problem, but latest update I have done with this .bpo-kernel
booted…
Now I still have no internet on main OS after 1min…
Please help.

i don’t think 1 minute is a problem,
maybe you can try with other drivers compatible for you
but just for few seconds or few minutes, afaik i’ve seen in many devices

I have internet only for one minute and after that is gone. I cannot even do update with it now…
I can only reinstall whole system?

Do u get it back after restarting NetworkManager or after a sleep and up again?
Well i never heard of this, maybe you can try installing compatible drivers for your card?
As some cards are not supported by the latest kernel you can try using the older version.

No. Restarting NetworkManager doesn’t back internet connection again.

This is screenshot on loadedd older kernel 5.14.0.-0 where I have connection:
