Predator neo 16 wifi card not working

Buttons (any button) can disappear form the taskbar, Desktop or Start screens, nothing to do with drivers or adapters, Google the issue and you will find solutions to get a button back. For Wi-Fi that would be typing WIFI in the search bar and you will get the Networking and Internet screen, turn on the Wi-Fi switch and click on the Wi-Fi box. Show available networks and manage known networks would be next and add a new network if you don't see your router.

If none of this helps, I recommend you restore your system to an earlier date before the problems started, this will refresh the registry and system files: Type restore in the Search bar and click on Create a restore point. Click on Restore the system to an earlier point and chose a date. When you don't see any restore points or get a prompt that the function is not working it means this very important Windows feature was turned off and I advise to turn it on and leave it turned on.

Uninstall the driver(s) with the yellow exclamation mark(s), reboot and then do the Restore system to an earlier date, you should have a restore point before the September 14 Windows update, I would use that and check for updates after that as it will uninstall the Sept. 14 update.

Yes, you have to uninstall every driver with yellow exclamation marks and greyed out Unknown Devices, System Restore will not install drivers it will only restore the registry and system files. Check also the hidden devices in Device Manager for issues. Don't reinstall drivers, let Windows11 find compatible Wi-Fi drivers, connect a LAN Ethernet cable to your router, make sure internet is working and just reboot.
