Encryption and settings baffling.

You need to setup your router to enable the DHCP server. Then, on your client computers, you want to select the option for them to obtain their IP addresses automatically from a DHCP server. Once they get an IP address from the router, the Internet will probably work - all the settings you need should be handed out by your router.

You do not have to use the DHCP on the router. I have 9 computers 2 which are servers and 5 of them are wireless to a dsl router, all have static IP addresses and work fine. The modem really doesn't have anything to do with this issue if you can get out on anyother PC. If you are using WEP, this is most likely the issue, make sure that if you have anyother firewall in between your wireless PC and the router that it allows access to the route, make sure that the router is your default gateway, and if you set mac control make sure that all wireless PC's are lsted with the proper mac address, get that by ipconfig/all at the cmd prompt.

DudeDomain you're right, you don't have to use the DHCP server as long as you set up everything manually correctly. However, on most networks, its convenient to use the DHCP server because it does everything for you and will save you some effort.
