Windows 7: Wireless internet works, wired switch doesn't

Wireless internet works, wired switch doesn't

This problem appears to be a variation on the hardy perennial "foo" doesn't have a valid IP configuration" problem.

My Windows 7 machine originally had a DSL connection through a router using an Ethernet cable, and it worked great. I used the same router for wireless and to connect with a home network to my other computers running XP Pro.
Then I changed to FIOS, and a new wireless router that had to be located in a non-wire-reachable location. No problem, a USB wireless dongle and the Windows 7 box was happy again and could see the internet via wireless.

However. I could not connect the rest of my network, also in the non-wire reachable location. I want to use the main box, the Windows 7 one, as the internet connection and connect the printers and other computers to it via cable and a switch. The LAN is showing as the dreaded Unknown Public connection which cannot be reset, the diagnosis is "doesn't have a valid IP configuration", and I've tried setting up ICS, making sure the security settings for files is NOT 128 bit, the IPV6 and 4 are set to automatically gather IP settings on all machines, and I'm running out of ideas. I don't let Microsoft automatically update anything, so I don't think it is a driver issue. The Windows 7 ethernet card worked great when it was the only connection. I *think* I saw a connection on one xp pro box before changing the IPV settings on it, but I can't be sure. I got a brand new D-link ethernet switch to try and make this work, both connector lights are green but no data is being exchanged.

Here's the latest ipconfig -all

Hi wish I could offer a solution but I cannot unfortunately....


I am actually wondering if you could help me out I also have a Zyxel G-220v3 usb wireless adapter that I bought from Verizon Dsl Dept. Since Zyxel has made this verison of the card only for verizon dsl customers the software cd that came with it is unreplacable!

I was just hoping that you might be able to send me a copy maybe by email?

hi there maybe you should try this out:
start your machine in safe mode
logon as administrator
open cmd.exe
type in: ctrl+shift+enter" to allow elevation request
type in again: netsh winsock reset" press enter
then restart your machine and start it in a normal way and hope the problem will be gone.
