Hi,

Are you using T1 Cross over cable?

When you connect the cable, do you see link lights on the routers?

if yes, are the interfaces in up and up mode?

I made a crossover cable using some cat 5 cable I had in my basement. When I plug up the I do not see any link lights come on. I long can the crover cable be? I think the one i have is 5 feet.
