Do the wireless security settings on the router match the settings on the laptop? In other words, check for WEP or WPA settings. On the laptop there should be a wireless app that tells you what WiFi sites are ative near your laptop. Check the default wireless settings on the router or in the router's manual and look in the WiFI app to see if your router's SSID is broadcasting.
