Connecting two routers together?

I have 2 wireless routers, one is 2 years old (duo Plus 300wr) and the other is new (Netgear N300 ADSL2+) as we upgraded. What I want to know is how can I hook both modems up together i.e i've left the old router connected to the ADSL line as the new one tends to automatically disconnect, I want to hook the new one up to the old one via an Ethernet cable and would like both modems to be independent of each other except for the new one getting the data through the Ethernet cable. What i did manage to get right was disabling the DHCP server on the new modem but would like to do this without disabling it on either modems. Thanks in advance!

    Hey Justin, just a few tips:

    1. Connect to your old router and go through the screens and write down the settings. You'll need these to set up the new router correctly. In particular note:

    - Any WAN IP settings

    - Any LAN IP settings

    - Any DHCP settings

    - Any Wireless settings (SSID, WPA2 phrase, which channel is used, etc.)

    - Firewall settings (high, medium, custom settings)

    - Admin Password settings

    2. After you've written down the info, while still on your old router, change:

    - Your router's LAN IP address from 192.168.1.1 to 192.168.1.2

    - Turn Off the DHCP function

    - Save your changes.

    3. Connect to the new router and configure:

    - The WAN IP info using your notes.

    - The LAN IP info by using IP address 192.168.1.1

    - Turn On the DHCP function and start your range after a little gap. Try 192.168.1.50 for 30 devices.

    - The Wi-Fi settings using your notes. If you space out your channels by 5 you can use the same SSID. For example, if your old router was using Channel-1 for Wi-Fi, set your new router to use Channel-6.

    - Make sure the Firewall is on (high or medium).

    - Either add a new Admin ID & password or change the default one.

    - Save your changes.

    4. Connect the new router to the DSL line and test:

    - Connect to the new router using an Ethernet cable. Can you access the Internet?

    - Connect to the new router via Wi-Fi. Can you access the Internet?

    - Turn off the Wi-Fi function for now. We'll turn it back on later.

    5. Connect the old router to the new router using an Ethernet cable. Plug into the LAN-1 ports on each router (although it doesn't matter which LAN ports you use.)

    - Connect to the old router using another Ethernet cable. Can you access the Internet?

    - Connect to the old router via Wi-Fi. Can you access the Internet?

    6. Connect to the new router and turn its Wi-Fi function back on.

    7. Connect your equipment to the new router configuration and enjoy!

    It would actually be easier to disable the DHCP on the old one, and set the new one back to DHCP using the same IP addresses that you had before. Also, make sure that you set the IP address of the old router to a differnt IP than the new one. i.e. If the new IP address is 192.168.1.1 and its DHCP range is 192.168.1.100 thru 254, then set the old router IP to 192.168.1.2 or something between 2 thru 99 that is not in use. Then plug the two routers together using the standard network ports, and as long as you have the SSIDs of each router different, you should be OK.
