I updated my Windows 8.1 HP Pavillion e118dx computer just after purchasing it. Since the update, both my wireless and ethernet connections are labeled as "limited" and I can't access the internet. ipconfig /all returns no information. I've tried rolling back both drivers, and also tried using every version of the drivers currently on my computer. I installed the drivers from the HP website, and still I can't connect. Can anyone help or offer more troubleshooting advice?
