Unidentified network, no network access

[Jstuts5797]

Ok so I know most of you will probably say there are a million other discussions and fixes out there for this issue, but none have worked for me this far. When I try to run windows network diagnostics I get a "local area connection doesn't have a valid IP configuration" I've tried resetting the network card flushing the DNS, ect and I always end up with the same thing. I've stopped the bonjour service from starting up. This is occurring on a laptop that before about 2 weeks ago the wired connection worked fine (no wifi) and this happened suddenly over night. Some things to note, I can ping my computers IP address just fine. When I look at the IPconfig page some things I noticed that are weird to me: my network adapter that is listed has the IPv4 autoconfigure address as: 169.254.71.252. My provider says this tells them that something is blocking the connection. Also for default gateway, it's blank, nothing listed at all. Also listed are two "tunnel adapters" that I'm clueless about. One is "teredo tunneling pseudo-interface" under it it says media is disconnected, physical address is all zeros says DHCP is not enabled but autoconfigure is enabled. That's all the data for that one. The other is "tunnel adapter isatap.{bunch of numbers here} it's median state is also disabled along with DHCP. Auto confignis is also enabled. All other devices on my network work both wired and wireless. I tried unplugging the network cable from my laptop into my PS3 and it works just fine so I know the problem isn't there. I believe I have disabled all anti virus and firewalls as well. I'm really not sure where else to go from here and this is really frustrating me. If anyone can give me some kind of guidance that would be great! Sorry for typing errors... Typing this all on my iPad because it still gets an Internet connection. Thanks in advance for all your help!

To follow up, yes I did try the changing MAC address trick... Still a no go

I know you said your ipad gets a connection; but even with that i would try resetting your network(power cycle). Unplug the modem and or router or combo modem/router if thats what you have; wait about a minute or so; then plug it/them back in and let them boot fully. Give this a shot and see what happens. If this does not solve the issue; post back and we can take it from there.

I tried that already as well. It's a combo unit. It'd actually the arris gateway that's used for everything... TV, internet, phone, and DVR whole home thing

Also thanks for responding so quick! =)

I have also now tried booting into safe mode and its still a no go.

Curious.... I noticed iTunes updated around the same time that this started. Is it possible that's caused an issue? I'd hate to uninstall it as that has my entire music library, iphone and iPad backups, plus I'm an iTunes Match user. But if it's possible this would fix my internet connection, I would!

To help posted below is a photo of the IPconfig /all of the problem computer. Going to log into the forums on a borrow laptop that is connecting to post a working IPconfig /all for you guys.

Sorry for the double pic posting above. Must have been a glitch on the ipad. Anyway below is the ipconfir /all from a borrow laptop that is connecting both wired and wirelessly:
