I actually tried that first but for whatever reason it wouldn't get an ip address. Maybe it's still part of the issue with dd-wrt. Assuming I can get it to work, will computers that connect to the second router still get an ip assigned via dhcp from the first router?<br>

I am not sure what you are trying to do, but your setup seems odd to say the least. Forget what you are doing, tell me exactly what you are trying to accomplish.<br>

Router 1 connects to my modem and until I added router 2 it was the only one on the network. However, for some reason, computers running Linux and with a broadcom wifi are having trouble connecting to the linksys. As this was creating issues with networking for the family I stuck the dlink into the mix so they could connect while I worked on figuring out why the linksys was having issues. However, once connected it was not possible to admin the dlink router as it was on a different subnet. I had a set up like this in the past with different subnets so that my home network was shielded from an ssh box I was running on the other subnet. However, in that case the home network was downstream (i.e. the second router) and was able to see upstream connections (computers on 192.168.2.x could see 192.168.1.x or maybe it was because router 2 was plugged into router 1 and router 1 plugged into the modem). In the new scenario, the dlink is the downsteam one (i.e. plugged into router 1 and my desktop also connects to router 1) and couldn't be seen. I really didn't want to move everything around but I figured that if I changed the subnet mask then everything would be able to see everything. My thinking was that computers on differnt subnets can't see each other if the mask is "masking".<br>
<br>Now, if that doesn't make sense it's probably because I have just enough networking knowlege to cause problems and don't always understand why things work the way they do. Doing as Mitch suggested (lan to lan) with everything on 192.168.1.x and no dhcp on the dlink solved the issue - albiet not in the way I was trying to. I was hoping to gain a bit more understanding of subnets for now the problem is solved.<br>
<br>If you know of any good and simple resources that would help me to understand this stuff that would be great. Most things I find don't really simplify. I need a children's guide to networking with nice pictures :)<br>
