It turns out that setting up wireless with DSL is a bit different than with cable modem, here’s how I got it to work.
In order to get it working I used a Cisco 678 DSL Modem, Linksys WRT54G Wireless Router and a Basic 5 port hub.
Here’s the process that I went through to get it working.
The first thing I did was to enable the DHCP Server on the Cisco 678. Be sure to set the starting IP address and DNS servers on the Cisco, or it won’t work properly.
DSL Modem Setup:
Here’s the part that I had to call tech support for help with. The wireless router must be on a different subnet than the Cisco, or it will not work properly.
Wireless Router Setup:
The wireless router should be setup to get an IP address automatically, which is the default setting on the Linksys.
I also set the DNS servers on the Linksys to make sure that they would be set properly on client computers. It may work without this, but setting it here avoids possible problems.
Run a cable from the Cisco 678 to the uplink port in the hub. Then plug the wireless router into the hub as well, and you should be good to go.
If you plan to use your network for gaming or other network applications, it is important to have all of the computers on the same subnet. This would mean plugging any computers without wireless cards into the Linksys.
