Help setting up a network with dd-wrt pleaseThis is going to be a semi-complicated network

This is going to be a semi-complicated network setup. I have a dlink DIr825 as my main network router. I want to connect 3 linksys routers wireless as repeaters. All 3 linksys routers have the ddwrt firmware installed. 2 of them are wrt54g's one with speedboost one without and the other is a wireless n linksys i forget the model number. Basically what i want is the dlink to connect wireless to the wrt54g and give it internet access through the wireless and lan ports (i have succeeded in this step setting it to repeater mode and same ssid and connecting through site survey) The problem im having is i want to re-repeat the first wrt54g to a second wrt54g in the yard (in a sealed waterproof box) but im not having any luck. Both routers at the moment are on the floor in front of me. Router A has internet access from the dlink but router b is not getting a connection from router A. I set it to repeater mode and set the same ssid as router a and connected to router a in site survey but it said no internet access. I also tried repeater bridge and this worked but now router a has no internet connection for some reason. Any help would be appreciated and another note The dlink can not be modified at all except with official firmware and official settings as it does not belong to me its my mothers.
