Like he said, make sure you check both computers and the manual for more instructions. If all else fells backup your settings to a floppy or jump drive and run a factory restore for the router.

my first question would be- is the cablemodem connected to the internet correctly (username/password and all that)?

second, is the router acting like a DHCP server for the home network (meaning does it handle all automatice assignment of IP addresses to computers connected to it)? if not, then maybe you need to assign IP addresses in the range the router expects.

answer these questions, and we'll go from there.

Make sure that the DHCP is connected otherwise it wont give you an IP and your internet will not configure. If its not connected, turn the power to the cable modem off, then put it back in.

ok- normally it's a good thing to give advice, but it's a bad thing to give wrong advice. Critical, turning off and on the cable modem will have nothing to do with changing a setting in a router configuration screen(s). this is also true if the cable-modem and router are combined in the same box. shutting it off then back on again generally has no effect since the settings are often stored in some kind of flash rom/eeprom bios-like chip-thingy. if not, then shutting it off might reset the device, which means entering all your connection data back into it. (yes i agree resetting it might turn on the DHCP service again, but i think that is over-kill for the posters current problem)

yes, but what worked for you- in your specific case- will not work for others. since i doubt you can see into his bedroom to diagnose the problem, giving him specific instructions for something he does not have will not be the solution.
