How do I connect two routers and have one wifi the other not.
I have two routers; One is a Linksys WRT54g I flashed with DDWRT and the other is a Netgear wireless N router.
My Comcast enters the house upstairs and goes into one router the netgear, I will only have wired users use this router so I have disabled the wireless. I have a 80’ cable plugged into this router that goes downstairs to the other router and plugs into it. I want to use the downstairs router for wireless only for laptops and iphone, so I will set the mac filter for specific IP’s, this should keep any other wireless users off that wireless network.
My question is how do I connect the upstairs router to the downstairs router so that I can keep wired users plugged in (running DHCP) and then have DHCP running downstairs on the wifi router, yet the downstairs router is plugged into a port on the upstairs router that is DHCP.
Can someone please help me out or make a suggestion to get this to work.

The Netgear router is capable of being a "Hot Spot Only" unit and not acting as a router. If your DDWRT router is not capable of doing the same I would simply swap the routers positions and set the Netgear to act as a hotspot.

I understand that but how do you set Router 1 as DHCP coming from the gateway (comcast) whihc will automatically take an assigned ip and then assigne dhcp addresses to the wired clients, keeping in mind that one port has a 80' cable that connects the router downstairs which broadcasts the wifi signal for wireless clients.

What about bridging?
Router 1 has DHCP server on it enabled, three ports are for computers upstairs, port 4 is a 80' cable that goes downstairs to the DDWRT router. If I plug the dhcp cable into a router then that router should be set to DHCP address. Will it still be able to hand out a dhcp address to the wifi clients on its mac list and accept additional wired clients?

The Netgear router will supply IP addresses to any device it sees on the network, whether that device is wired or wireless. If you are trying to supply wired clients from one DHCP server and wireless from a second DHCP server you will get serious problems.
I would suggest that you use DHCP throughout, limit the number of IP addresses to the maximum number of devices you are going to use and then use MAC address filtering to prevent unauthorised access.
You should note that if you are using MAC filtering instead of encryption, like WPA or WPA2, the solution is less secure as a packet sniffer can pick out the MAC addresses and these can then be spoofed by modifying the registry of a PC.

Hows this look?
RTR 1
WAN: Comcast dhcp
LAN:
Router IP: 192.168.1.10
Router dfg: 192.168.1.1
Router mask: 255.255.255.0
Static IP’s 192.168.1.11 – 13 PC’s
Router two: 192.168.1.14
RTR2
WAN:
192.168.1.14
192.168.1.1
255.255.255.0
LAN:
DHCP scope(8)
192.168.2.1 - 8
Static route: ip route 192.168.2.0 192.168.1.0
RTR 1
WAN: Comcast dhcp
LAN:
Router IP: 192.168.1.10
Router dfg: 192.168.1.1
Router mask: 255.255.255.0
Static IP’s 192.168.1.11 – 13 PC’s
Router two: 192.168.1.14

LAN:
DHCP scope(8)
192.168.2.1 - 8
Static route: ip route 192.168.2.0 192.168.1.0
The one router will not see the other with that subnet, use 255.255.0.0.

So use 255.255.0.0 on Router 2 or what about changing Router 2 to the following?
RTR2
WAN:
192.168.1.14
192.168.1.1
255.255.255.0
LAN:
DHCP scope(8)
192.168.1.100-105
RTR2
WAN:
192.168.1.14
192.168.1.1
255.255.255.0
LAN:
DHCP scope(8)
192.168.1.100-105
You need that subnet mask on both routers, as data travels both ways.

But 24 bit mask would not work on both?
