Things can be complicated sometimes and might take a while to resolve an issue. Can we try something else?
Log on to Safe Mode with Networking by restarting your computer, then tap F8 and select this option.
From here, uninstall the Netgear adapter from Device Manager, then reinstall it back.
Then, open up a command prompt and type ping 192.168.1.254 then press enter and post the results on your next post.
Also, is there another computer in your network that you may run the ipconfig /all command then post it here?
