What is the exact model of Netgear router? Please post that information.
If the router is a combination wireless/wired router, connect a computer to one of the router's wired Ethernet ports and see if you can access the Internet that way. That will give us a better idea of exactly where the problem lies.
Also-
1. Do the status lights on both the DSL modem and the router indicate that they are communicating with each other?
2. Are the computers receiving correct IP information from the router? Netgear routers usually assigns IP addresses from the 192.168.0 range to the computers they are connected to,and usually assign themselves the IP address of 192.168.0.1. On each computer, do the following:
- Click on the "Run..." option under your Start button menu.
- In the resulting dialog box, type "cmd" (omit the quotes) in the "Open:" box and then hit enter. This will open a DOS window.
- At the DOS prompt, type the following command and tell us what it reports:
ipconfig /all
You should get something very similar to:

Note the Default Gateway IP address. Type the following command and tell us the results (if ipconfig reports your default gateway IP to be something other than 192.168.0.1, use that IP in the command):
ping 192.168.0.1
3. DSL connections usually use a protocol known as PPPoE (or perhaps PPPoA), and your router must be configured to use that protocol as well if it is to communicate properly with the DSL modem. By default, Netgear routers use the DHCP protocol instead of PPPoE, and if the router did not automatically detect the right protocol for your DSL service you won't be able to get a connection to the Net.
You may need to check/configure this setting in the router's configuration utility; if you tell us the exact model of the router we can tell you how to do this.
