I have a Linksys Model WRT54G V2.2, 2.4 GHz with 54Mbps. With this I have been running my old Gateway laptop. The Gateway has physical issues so this weekend I purchased a new Toshiba laptop. First, the Gateway ran on Windows XP. I had no problems connecting to the internet with the Gateway. Back to the Toshiba: It has Windows 7 OS, and is a larger laptop in that it has 4 GB memory and 320 GB hard drive. When I attempt to access the Internet through the Toshiba it keeps telling me that my router isn't working properly. It suggests re-starting the router and modem, which I did. The Gateway worked fine, but the Toshiba won't connect to the Internet. Do you think I need to buy a new router? Or is there some sort of file I can download through Linksys that will enable me to access the internet with the Toshiba? Thank you so very much. Miss Vivian
