I started my computer today without being able to connect to the internet for some very odd reason. As the title says, that is the name of problem that the Network and Sharing Center says on Win7. Its weird though, because everytime I trouble shoot the problem it cycles through two answers. One time it will be the name of the problem above, and the next time it will say that my perfectly fine ethernet cable in not properly plugged in or may be broken. It also showed a 3rd problem sometimes saying my Realteak PCIe GEB Family Controller (gigabyte ethernet card) drive was bad so I reinstalled that and the error went away but not the problem. If you have any questions about my situation that could help you, then do please ask. I'm running Win7 64bit and connecting to the internet through a ethernet cable obviously. My Linksys router is fine, and I'm using another computer in the house to type up this problem here. Any help is very appreciated. Thanks. Update: A person on Superuser said that my DHCP is broken and that another NIC wont fix anything. |

The card could be bad. try a known good card in your computer. You could also try setting a static IP address to the card to see if that fixes the problem. I'm not sure what you mean by having another good card. Also I don't know how to set a static IP address up. "card" - Network card (i.e. the computer end of your connection) This is a network card: http://www.newegg.com/Product/Product.aspx?Item=N82E16833122133 This is how to set up a static IP: http://portforward.com/networking/static-xp.htm Don't worry about the port forwarding stuff, just set you IP address to a static one. On the last set of numbers for the IP address, I recommend using a high random number so you don't end up with the same address as another computer on your network. It can be anything from 1-254 I looked at the tutorial for Win7 and I can't setup a static up unless I am connected to my network. You can do it without being connected to the network. You are applying the IP address to the network card, not the network. Make sure you go to network and sharing center and on the left sidebar, click on manage adapter settings. Yeah, even in the tutorial, the guy is connected to the network. I don't get that button unless I'm connected to the network. Try installing a new ethernet card and see if that fixes your problem. I tried to setup a static ip and in the tutorial it said to use the same DNS which I saw in the ipconfig /all, but the server was "fec0:0:0:ffff::1%1" and when I try to enter that Window says,"You are trying to paste a malformed IP address into this field." Also the defualt gateway shown in ipconfig /all is completely blank. bump....... A person on Superuser (another Q&A site) said that my DHCP is broken and that another NIC wont fix anything.

Turn off the computer that's not working, the one that is, anything else connected to your network (switches, hubs, xbox, w/e), your router, and your modem (if you have one...). Wait at least 5 minutes, then fire them up in the order they come into your home, EX. modem, then router, then switch, then pcs. Even with one or more working computer, it can still be the router. I don't even know how many times I've seen this with a client's network. Try this, then post back. |

You can try using "Microsoft Fixit 50357". It may fix your problems http://support.microsoft.com/kb/928233 even though it may be for vista, it should be the same for windows 7. Used it before when there is some network troubles on my 7 machiene It said it failed to work on my OS (Win7). |

Have you tried some simple things first, like: Reversing your Ethernet cable (plug the end that is in the router into the computer's Ethernet card, and the end that was in the PC into the router). Or have you tried a different port on the router? Try another Ethernet wire. Disabling / enabling the Network card in device manager. Or deleting the Network card, rebooting and let Windows find the card and reload the device drivers. Each one of these things have helped me in the past more than once. |
