Hi:Here is a pretty good tutorial on that subject.
Tips on setting up broadband connection, courtesy of Johnwill
You don't need any setup disk to configure a broadband router.
Reset the router to factory defaults by holding the reset button down for 15 seconds with power on. The following procedure should get you a connection with any broadband modem that is configured to use DHCP for the router connection, such as cable modems, and many DSL modems. If you require PPPoE configuration for the DSL modem, that will have to be configured to match the ISP requirements.
• Turn off everything, the modem, router, computer.
• Connect the modem to the router's WAN/Internet port.
• Connect the computer to one of the router's LAN/Network ports.
• Turn on the modem, wait for a steady connect light.
• Turn on the router, wait for two minutes.
• Boot the computer.
When the computer is completely booted, let's see this.
Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:
NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous command output!
In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:
IPCONFIG /ALL
PING <computer_IP_address>
PING <default_gateway_address>
PING <dns_servers>
PING 206.190.60.37
PING yahoo.com
Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.
Also,is this a cable or dsl connection?

Also,since you did a re-install you may have to go to the Dell site and download:
Chipset driver for your model and any network adapters that you have.
