Which updates did you download and hopefully you didn't use any third part "driver updater" as those things should not exist.
Modem/Router:
1) Reboot you wifi-router, maybe even reset it to factory defaults
2) Make sure you do not use the default password for wifi-router management console, nor to wifi connection (WPA should be disabled as it offers no protection at all)
3) After setting those things and making sure there are no firmware updates available for your router, reboot it again
Computer hardware and software:
1) Clear CMOS (unplug computer from wall socket, ledt LEDs dimm out, connect CLR CMOS pins in right lower corner for a few second using a tip of screw driver)
2) When you boot up, set DOCP back on, enable fTPM, SVM, UEFI boot to Windows and what other settings you use and that wifi is enabled and if there is any bifurcation setting, it is on Auto.
3) Do not enable/install any internet enhancers, TurboLANs nor install Asus Crate - if you have any, uninstall them
4) Make sure you have wifi-antenna screwed all the way in.
5) Uninstall wifi-adapter from Windows and reboot
5) Reinstall wifi-adapter using latest drivers from Asus website
6) Go to Control Panel > Network and Internet > Network Connections -> right click on your wifi-connection and choose diagnose and let Windows do its thing.
If you use any VPN or 3rd party antivirus software, they can install a driver type of thing between network and operating system, which can be incompatible.
You can also try to connect your computers wifi to your smartphone by enabling HotSpot-feature on your phone. Smartphones tend to overheat soon if you use them to download large files (tens or hundreds of gigabytes), so this is only for temporary use and testing. Also if you live in some terrible country, they can charge you by how much internet you use.
