Conncting Linksys Cisco WRT300N and SMC WBR14-G Routers/AP

I have 2 wireless acces points serving two different networks. I want these two acces point to commnunicate to each other so both the networks can access all comuters. The first acceespoint is Linksys Cisco WRT300N Broadband Router and the second one is SMC WBR14-G. I tried using WDS from SMC but it doesn't work.
Pl. help.

If both are real layer 3 routers (as it appears to be). Then you would need a crossover cable to connect them and need to setup a seperate LAN for that line.

Or am I totally out of scope ?!!
