"WiFi adapter doesn't have valid IP configuration" - Help!

Although connected to the wifi, the access to internet is limited (none). I have tried everything people suggest on the forums. I'm on Windows 8 (lenovo yoga notebook)
when typing ipconfig it looks like this:

Wireless LAN adapter Wi-Fi:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . . . : fe80::e1e4:1d69:5de0:346f%3
Autoconfiguration IPv4 Address . . : 169.254.52.111
Subnet Mask . . . . .. . . . .: 255.255.0.0
Default Gateway . . . . . . . . :

(Yes, it is blank for DNS Suffix and Default Gateway)

Please, help. It is urgent.
Thanks for any replies

I already unsuccessfully tried....

to reset the wifi adapter, reset the ip protocol (somehow) through the cmd window. I installed updates for the Intel wifi adapter. tried to set the IP configurations manually several times... The only thing I haven't tried is reseting the modems as it is a school wifi. And yes, between it I restarted my computer at least six times.

When it gets that bad I....

I pull out the USB WiFi stick I carry with me and test with that. If that works I boot up a Linux off USB (there are many but right now it's Mint.) That gives me a good indication if it's hardware or an OS issue.

In that case I use a Wired Ethernet connection.

As to you thinking it's not a hardware issue, that's why I carry the spare and the other OS to test where the issue is.

I only assume it's not a hardware issue because I upgraded my adapter trying to solve it. wasn't better before nor after
