Question

Need help with a connectivity issue.

Oct 8, 2015 8:51AM PDT

I came home from work about a week ago to my wifi adapter saying limited or no connectivity. I have tried rebooting, enable / disable, delete and reinstall newest drivers, an older driver. moved on to sfc /scannow with no errors, have done ipconfig /flushdns ipconfig release and renew (with release saying no ip assigned and renew just hanging until i hard break it) netsh int ip reset netsh winsock reset netsh int.. ipv4 reset. And still I cant connect to the router. Every phone and tablet in the house still connects. I do not have physical access to the router as its a hotspot service so I cant check/modify anything there. And the really weird thing? At least to me, is Im able to tether my phone to the pc to use the wifi. Thats how I'm here.

OS: Win 7 Ultimate
Adapter: Netgear WNDA3100v2

Answer
The 169.254.234.41 is your clue

That the adapter and system could not establish a connection to the hotspot.

When I see this I boot up a LiveOS USB/DVD like Linux (no install) to see if it's a hardware issue. If I can't connect in a few Linux's then I try another USB stick. I carry spares on such calls.

Cant do a Nix boot

This particular adapter is unsupported in nix unfortunately. Or I wouldve immediately tried with my bootable usb of Kali

Now you see why I carry spares on such calls.

I decided the wifi adapter had just failed. I couldnt find any problems with the network protocols and I could connect wired to an old router I had laying around and login to the router, so I bought a new adapter, oddly enough same model and version because thats all the local store had in stock. Didnt install new drivers just hooked it up and was good to go. Thanks for your help anyways.
