Hi, I have an acer 2920 laptop (vista) and a belkin wireless router which used to connect to the internet with out a problem. However, after taking my laptop away with me and using the a hotels network without any problems I then returned home to find that the Laptop will no longer connect to the internet at home. On some occasions my home network is no longer visible? Please can anyone help? This has also happened once before and my boyfriend managed to fix it without even realizing what he had done?!?!}
