Problems with ddwrt router as repeater

So a while back, I set up a linksys router to work aa a repeater using ddwrt. I planned to hook it up to the surveillance system I set up and hide it somewhere. I’ve tried hooking it up to the router (wired) and it was not able to connect to the Internet. I tried connecting it to the main router and it worked perfectly. Same thing with my direct receiver. I also have a laptop that can only connect to the repeater and not the main router. Anyone have any suggestions of what I sould look at to make this work? FYI, the ssids are different
