In the Device Manager under Network adapters, there was a listing called "Microsoft 6to4" and it was not working properly. I uninstalled it and reinstalled it. It is now working properly, but is hidden and there was no change. All drivers are up to date. I also attempted to uninstall and reinstall The Netgear application but that also did nothing. I tried nearly all the solutions provided by this site (http://helpdeskgeek.com/windows-7/fix-unidentified-network-and-no-network-access-in-windows-7/) with no success. I tried resetting the TCP/IP in a command prompt but received an error message when attempting to input: netsh int ipv4 reset reset.log
I have a Hp w1907, using Windows Vista. My wireless device is NETGEAR WPN311 Smart Wizard. I am very frustrated and any help would be very welcome.
