I have this problem too,
my pc was fine (desktop running 8.1), i reset it because the internet was being slow and the connection is permanently 'limited' now.
if i boot in safe mode i can connect to the internet. i tried wired and wireless (which usually use) and they both show limited.
I've followed a tonne of guides which had me refreshing my ip addresses and checking for malware to no avail. I've reset the network devices and rolled back their drivers.
other computers are working fine on the same connection.
just to top off the annoyance, i cant run a refresh because it says its missing files. My version of Windows 8.1 was upgraded from 7 originally, i have no idea what the key is and my original boot disk is Windows 7 SP1.
also how am i supposed to install any updates if i cant connect to the internet?
anyone know what to do?
Update:
I tried all advice that I was directed towards to no avail.
I've now reinstalled windows 7 and there are no connection problems.
This rules out and hardware issues with my pc or my router and points the finger at windows 8.
my motherboard is an ASUS P9X79 pro, does anyone have something similar and also have windows 8 problems?
Thanks for you help,
Will.
