Initial setup issues

Hello, and accept apologies if this is old and already discussed, but I couldn’t find it. I have had a Canopy system passed on to me for set up, and we successfully connected through one AP to one Linksys WAP from a switch on my internal (class C) network., but when trying to connect to a Linksys Wireless Router from one of my routers, nothing goes. I did take the router into the computer room and direct connect into the ethernet port on my Cisco 7206 and line protocol came up immediately. Most of my router connections are T1, so I have a spare (int eth 2/2) which I gave a new network IP to and set the linksys on the same network, Any ideas, or if anyone wants to help but needs more info, just ask. And Thanx in advance!!
