Wireless Network comes up as "Unidentified Network"

I have a Windows 7 x86 Operating system on a HP Pavilion g6, and in my network list, I have 3 networks. "Network 1" (Hamachi), "Network 3", LAN, and "Unidentified Network". Strangely, any wireless connections appear as "Unidentified Network", and although everyone else can connect just fine, it says "No Internet Access". If I unplug my LAN cable, it still doesn't work. The network has the icon for a public network, (a park bench), but I have no way of changing the network type, though I can change the network types for my other networks. Previously, I had the problem, and I just upgraded my router, I have the same problem. Although It's not critical, it would be nice to be able to use WiFi.

The Hamachi interface has been causing this type of problem with the typical "Unidentified network" with wireless connections lately. You might try updating the Hamachi interface or working with the settings.

Disabling or uninstalling Hamachi seems to solve the problem.
