Connecting to Network Drive NAS 110 SeaGate

This is AT&T 2WIRE Modem/Router DHCP Setup Page! How can i setup my 2nd Router to be the DHCP and not this one??? :)

The best and only way to do this in my opinion is to remove one of the routers from the system and don't use the A/P as a pass through switch. You want to plug the A/P into another switch and don't plug another router into the A/P, then remove one of the routers from the equation. I would definitely go with the Cisco router first in the system as the main router rather than using the ATT modem router combo which should be tossed. :)

Using dual routers in a single network is a hit or miss type of deal and no matter how well you set them up it may not be reliable. I won't get into the fact that every time there is a power outage you will need to go in and re-set up the secondary router all over again. Configuration files come in handy for this.

If you want a chance at getting this set up for dual routers the link below might help you get all the setting correct.
