I have 2 linksys routers that are WRT54GS, and one that is WRT54G. Very similar models, except for the speedboost difference. I previously had just the WRT54G hooked up and it works fine. I decided to add two more routers to the other parts of the house (in a series, first router connected to second router, and then second connected to the third). I can get the second router to work (DHCP off for routers 2 and 3). But when I plug in the third router, I can not get internet. Even more interesting to me is when I connect my computer to the 3rd router, i can ping only the first router. (I also made router 1's ip 192.168.1.1, 2's 192.168.1.2, and 3's 192.168.1.3) I can not ping router 2 or 3, even though I am dirctly connected to it. I have tried both 2nd and 3rd router in gateway and router mode under the advanced settings, but I can not get it to work. Any suggestions are appreciated. Thank you.
