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? Jul 19, 2012 at 20:58
  • What does ipconfig in your command prompt yield?

  • 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'?

  • I have checked all the settings for ipv4. It is auto dhcp and ipconfig looks normal minus an invalid ip address.

  • @TheX could you update your question with the output of ipconfig /all?

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.

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.

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.

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. Jul 19, 2012 at 21:56
  • AFAIK, gateway is "required" for Windows 7, otherwise network will be "Unidentified".

  • 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 ;) Jul 20, 2012 at 8:59
