Help! I have an Unidentified Network (Home) with no internet access. I am running Windows 7 Ultimate on a Dell XPS on a Home LAN connected via a switch to a Verizon-supplied router. My router address is 192.168.1.1, but the Dell is unable to access it. My two other computers (one running Windows 7, the other XP) are also on the LAN connected via the switch and are fine. My Dell has an NVDIA nForce NIC. I have read a considerable number of posts and have tried the following: 1. disable/enable network adapter (though it hangs) 2. uninstall/install network adapter (this also hangs) 3. ipconfig /flushdns and /release and /renew 4. netsh winsock reset 5. Route delete 0.0.0.0 6. assigning a static IP address and DNS address and returning to dynamic for ipv4 and ipv6 7. assigned the default gateway (which was at various time either blank or 0.0.0.0 to be the same as the IP of the router) I have tried other solutions as well, but at this point I have changed so many settings that I am hopelessly lost. I should add that my Dell was working fine in terms of internet access for several months. Also, ipconfig /release seemed to have worked last week when I lost then regained internet access. Any suggestions would be appreciated. Thanks.

First and foremost ensure network adapter is detected in device manager with no exclamation. Next logged into the switch as well as router config page and ensure dhcp is selected instead of static, thus it would assign a dhcp ip. Once done, save prior to existing Reboot your pc and see how it goes

I cannot log onto the router from my Dell, only from the other two computers on the Lan. The router page says that the connection type is DHCP, if that is what you meant. I don't know what the IP address is for my switch. I rebooted and there is still no internet access.

Since you have no idea what the IP for the switch and router, if you could tell us the make and model for both device, that would helps. For the IP of the router and switch, you could go to cmd prompt and type ipconfig /all and hit ok, the default gateway IP should be the router IP, once you get the IP, type it on the url and logged in from there, provided there's no ssid or passphrase enable.

Actually, I know the IP address for the router and can log onto it from the other computers on the LAN. However, when I try to log onto the router from the Dell, nothing happens. Using ipconfig /all, the default gateway for the Dell shows up as blank unless I manually set the detault as the router IP address by setting a static IP address for the NIC's ipv4 properties. However, when I use a static address, the DHCP is no longer enabled. The switch is a Linksys "Etherfast 10/100 Auto-Sensing 5-port Workgroup Hub", Model # EFAHO5W". While I don't know the IP address for it, the router lists 4 devices (IP-STB1,2,3, and 4) with a Coax connection on its home page. However, I cannot log onto any of these IP addresses from any computer on the LAN. Thanks.

Hi, The issue could be affected by many factors. It seemed the computer cannot get the IP and DNS successfully. You can refer to the following method to test the issue. 1. Reset the router and update its firmware from the manufacture's site. 2. Change another Lan Cable. 3. Perform a Clean Boot and then remove and reinstall the network card device from Device Manager. If it hangs, let me know what error is received. 4. Ping router. 5. Contact Dell support to confirm if the network adapter hardware works properly. http://support.dell.com/ Note: Since the website is not hosted by Microsoft, the link may change without notice.

I had tried these before, and the only one I had a problem with was pinging the router from my Dell. Pinging from other PCs on the network was fine. I was about to go through all the solutions one more time, but after three weeks of no internet access from the Dell and dozens of reboots, on the last reboot with no apparent reason, the default gateway reset itself properly and my Dell now has internet access. So thanks to everyone who read this posting and offered solutions. I have no idea why my PC is now working fine. But in any case, we can close out this posting for now and I will return to it the next time i lose access.
