No matter what I do I am unable to get a windows 7 computer to connect to any networks. Wired or wireless, I always get a "limited access" error. I have searched google for possible solutions and have been u able to find any

Gonna need more info. Is this DHCP? Static? – hydroparadise Jul 19 '12 at 20:58
What does ipconfig in your command prompt yield? – user142485 Jul 19 '12 at 21:01
While connected to a network that should give you access: Go to Control Panel>Network and Sharing Center>Wireless Network Connection (or however you are connected)>Properties>Click on Internet Protocol Version 4 so it is highlighted>click properties. Is 'Obtain an IP address automatically' selected along with 'Obtain DNS server address automatically'? – user142485 Jul 19 '12 at 21:07
I have checked all the settings for ipv4. It is auto dhcp and ipconfig looks normal minus an invalid ip address. – TheXed Jul 19 '12 at 22:16
@TheX could you update your question with the output of ipconfig /all? – Jul 19 '12 at 23:00

I had this problem for the longest time when troubleshooting my neighbors computer. After about a four hour headache I ran System File Checker. This fixed it instantly.

Yeah yes I remember having to do this before. Thanks for reminding me. I will let you know if it works. – TheXed Jul 20 '12 at 1:38

Try uninstalling the driver and reinstalling the driver and reboot your computer I encountered a problem similar to yours at a pharmacy that needed technical support.

Also try to reset the router and then see what happens.

Whoops wrong answer. – TheXed Jul 20 '12 at 1:37

Its most likely a driver error. Check your device manager and make sure that you have a network adapter driver, and that its up to date, (IE there isn't a little exclamation mark next to it.) If you recently installed windows, its possible that you either didn't install the network card/driver, or that its not properly configured. What kind of laptop do you have? I would recommend going to the manufacturer site and manually updating your drivers.

I have tried 3 different network adapters 2 of them I know work. – TheXed Jul 20 '12 at 1:28

Seems like you don't fill "Default gateway" for TCP/IP v4?

Default gateway is not required for IPv4 but it is sensible to use it. For DHCP, it should be set for you though not all routers provide it. – Julian Knight Jul 19 '12 at 21:56
AFAIK, gateway is "required" for Windows 7, otherwise network will be "Unidentified". – Maximus Jul 19 '12 at 22:57
You might be right about W7, I can't confirm because all of my networks have it set correctly - I am "old school" after all ;) – Julian Knight Jul 20 '12 at 8:59
