Let's address your concerns.
We don't do live chats, or one on one help, we keep it public in the open forum so others can chime in with assistance.
This way, anything mentioned that helps can be searched for, and accessed by others, later down the track.
As to Norton's, yes it can always be reinstalled.
Best way is to go to their website and download your product from them.
You would have needed an installation key to install it initially, so you either use the same key, or login with your Norton's Account, where they already have your subscription details.
But really, the inbuilt Windows Security Centre, running Defender, is all you need these days, been that way for maybe 8-10 years I reckon.
Defender ranks as good, or better, than the paid-for products in any independent test I have seen.
Also yes for the wireless adapter.
Uninstall it and have Windows automatically reinstall it has it discovers 'new' hardware when you reboot the PC.
But as a precautionary measure, you can always pre-download the wireless adapter driver from here;

Enter your serial number, or product number, to see the list of drivers for your laptop.
You should do this anyway, because if the uninstall/auto-reinstall doesn't work, this will be the next straw we clutch - installing the latest driver.
