loss wireless internet once connect to a wire router?

The wireless PC defaults to the wired-LAN connection when connected. The PC cannot connect to multiple networks at the same time so it picks one in a pre-determined order. You would need to bridge the two connections and make sure settings such as DHCP range, and gateway addresses are not conflicting. This would cause your computer to effectively use both networks as one. This would also, however, cause the wired network to have internet access.
