You have a problem: there are six computers in your home or small office and they need to share the Internet connection provided by a single DSL modem. Luckily, there is a solution. There are several networking techniques you can explore, and then pick based on your available hardware and proposed networking layout.
Using a Router
Consider sharing your DSL through all six computers by connecting those computers to the same router. You can purchase a router that allows both Ethernet-cable based connections and wireless connections. You connect the DSL modem to the router by plugging an Ethernet cable into the modem's Ethernet port and then plugging the other end of that cable into your router's "WAN" port. This way, you can set up a home network managed by the router that also has access to the Internet through your DSL connection.
Depending on your Internet service and its provider, you may be able to use a wireless DSL modem to share your Internet connection across all six computers. All computers will need a wireless network card. You will need the network security key as well as the network name. This information might be contained on a sticker on the wireless modem, or in your subscription information from your ISP. Click the "Network" icon in your taskbar. Click the name of your modem's network. Click "Connect." Enter the security key when prompted to do so and click "OK."
If you don't want to use a router, you can network your computers together using an Ethernet hub. You'll need Ethernet cables for all six computers, as well as one for the DSL modem. Make sure the hub is in a spot where all of your Ethernet cables can reach it. Plug each cable from your six computers into an available Ethernet port on the hub. Make certain that there is one left over for the DSL modem.
Choosing the Best Solution for You
Picking the solution from those outlined above depends on your networking needs and hardware. For example, if your ISP has already provided you with a wireless DSL modem, then networking all of your computers using that method saves you from having to purchase a router or hub. If your modem doesn't support wireless, and you have both wired and wireless devices, then buying and setting up a wireless router is your best solution. If all of your computers are close together and you already have the required Ethernet cables, then setting up a hub might be the fastest and best solution to your networking needs.
