Went through HP support with out any joy. Reset router and modem. Used MS tool to verify router is fully compatible with Windows 7. Cannot ping the router, nor execute an ipconfig /reset. Tried new network card - same thing.
There is no default gateway showing up which is a problem. It may help if you enter your default gateway and IP manually by going into your ipv4 connection properties and manually entering the default gateway and IP address.
Default gateway is usually 192.168.x.x, X depends on what router you are using usually 0.1 or 1.1.
This is supposed to occur automatically if you are using DHCP in your router and Windows 7 settings. I'm not sure how Windows updates could have caused this problem but it's been happening a lot lately.
I helped fix this same problem just the other day, thread in the link below. "Doesn't have a valid IP configuration"
