If you do not have a router you have to reboot the modem first, Modems pair with one device at a time using its MAC address, using a router allows you to add remove computers to your internet access without rebooting the router for every device because the modem pairs to the router and the router shares its internet with your other devices.

I need a driver for my speedstream 5100 modem

No, you don't need a driver.
Just use an Ethernet cable to connect from one of the LAN ports on the modem to the network port on your computer, and you'll be connected.

Having trouble getting internet connection, from

Assuming you have connectivity to the router, 1st click start/programs/accessories/command prompt. Command prompt will be a medium sized box that pops up.
Will look like this where you start typing:
C:\user\computers name>_
just start typing, don't hit the space bar and type exactly what I type.

7 lines down, there will be a line saying "DEFAULT GATEWAY. . . . . . . . . . . .
The could be different. Write it down if you can't remember it.
Open your internet browser and type this number into the url bar( this is where you would type something like http://www.google.com at) This number will get you into the DSL router. I haven't been in this router in a long time, so my memory is a little sketchy. You should be able to access the connection page and manually make a connection.
Now this all depends on weather or not you have DSL sync with modem back to the phone co. If you can get here and you have connectivity with a solid DSL light, you shoud be able to surf. Also, from the command prompt, you can test your connection to the router by typing :
ping or what ever the default gateway is.(there's a space in between ping and the 1)
If you can ping the router anf the connection looks solid from inside the router, test from the command prompt to see if you can ping outside the network. Type ping www.google.com It should give you 3 replies from the site.
If this happens and you still can't surf, then you have firewall settings set to high or more troule shooting is needed.

Hope this helped.
