I have just returned from a weekend away where I was using my Dell Inspiron Windows7 laptop connecting to the hotel WiFi network with no problem (having done this successfully before elsewhere). Now at home I cannot connect to the Internet or my home WiFi network. I have the message Unidentified Network yet it also seems to show I am connected to my home network, yet I cannot access anything. We need to Skype someone in afew days time so need a solution quickly. Any suggestions.
