I have tried installing both linksys and also Dynex notebook cards following the instructions completely, but I can’t get either to install. I have a wireless router (linksys). After all my attempted tries at installation, I keep getting a message that I am not connected to the device. I got the laptop at a yard sale, and it originally came with a smartkey but the seller did not know the password anymore. So in order to use the computer at all I had to install a brand new xp program, to bypass not having the code for the original smartkey. Is this why I may be having problems with connecting? The previous owner had no trouble connecting to the internet, but I cannot because it won’t recognize any modem. Any ideas how I can get around this. I travel for months at a time and need to have some kind of connection to a modem, either for WIFI or for phone dialup. I am at wits end. Any thoughts?
