Your modem if it is a Speedstream 5200 does not have any wireless capability and as such, there is no need for a password. You can only use one computer connected with an ethernet cable to your computer. What you can do is purchase a wireless router, preferably a N series wireless router because it is stronger than a normal G series router. Normally your modem connects to your computer via the ethernet cable. With a wireless router, instead of plugging the modem to your computer you should plug it in router. From the router you can connect another ethernet cable and plug it in on your desktop. You can connect at least 4 wired computer to your router. For the wireless part, all they have to do is look for the strongest wireless signal then hit connect. If it ask for a password then it should be in the sticker at the side of the wireless router.
