Have you checked that the settings in the router are still correct? The power problems might have altered these so that wireless is disabled, the SSID isn't being broadcast, the encryption (WEP or WPA) has become corrupt etc.
It might be necessary to "reset" the router back to factory default settings and configure it again from scratch :-(
<<< also have a connection to a wireless calles linksys. This tells me I am connected but I cannot get to the internet. No idea what this is... >>>
Your Wireless Network adapter in the PC is picking up a wireless network from a neighbour, who is using a Linksys router and without changing the router's default SSID.
