Trouble Connecting Laptop to OpenWRT Router to Netgear Bridge

[webmanoffesto]

I want WiFi via my new TP-Link TL-WDR4300 and my old Netgear DN2200 to be the modem (in Bridge mode). I successfully flashed OpenWRT (Barrier Breaker r40887) onto my TP-Link. I set my Netgear DN2200 to Bridge mode. But I still can't access the internet.

I called my ISP (Netvision). I entered my UserName and PW into the Netgear Router
Under "Basic Settings".
Entered xxxx@INetvision and the correct password, and successfully connected to the internet. (Worked: Laptop<->Netgear(with Username and PW)<->Internet)
In this setup I can Ping NetGear at address 10.0.0.1.

Then I did
Laptop<->TP-Link<->Netgear(with Username and PW)<->Internet
That didn't work
In this setup I'm able to Ping TP-Link at 192.168.1.1
but I can't Ping NetGear at 10.0.0.1
What do you think the problem is?

Also, I think that my UserName and PW should be entered in the TP-Link OpenWRT router, not the Netgear (bridge).

I'm on Windows 7. I can boot into Ubuntu.

Problem solved.

This is now essentially two networks. The TP-Link network, and the Netgear network.
On the old Netgear router. I did Factory Reset and entered the username and password for the ISP.
I "created" a WiFi name and password (the router setup demanded it), but then disabled it (ESSID disabled, and don't show).

On the TP-Link OpenWRT.
I set the DNS address.
On the Interfaces / Wan I set the IPV4 Gateway to 10.0.0.138, which is the IP for the Netgear.

All parts are happily working.
