I take it you do not have a Hub or unmanaged switch.
Ok.
You are doing the Alternate Method that is addressed at http://www.dslreports.com/faq/7267.
If you had a Linksys router...
If a 10 Mbps hub and a second NIC or spare PC is unavailable, then the following configuration changes to the Linksys are required for accessing the modem through the Linksys. Unfortunately, this will cause a loss of Internet access.

Since you do not have a Linksys router, these are the correct steps for your router.
#1 In the Netgear router go to LAN IP Setup.
#2 It will look something like the screen that you see at

#3 If the LAN IP of the modem combo was 192.168.1.1 and the current LAN IP of the Netgear does not start with 192.168.1, you are almost good to go.
b) Otherwise, change the LAN IP of the Netgear so - for example it is 192.168.2.1, then go to step 4.
#4 In the Netgear router go to Basic Setup.
#5 It will look something like the screen that you see at http://screenshots.portforward.com/Netgear/WGR614v6/Basic_Settings.htm
#6 Select No, to Does Your Connection Require a Log-in.
#7 For the IP Address, select Use Static IP:
a) For the IP Address, enter in 192.168.1.6
b) For the Subnet Mask, enter in 255.255.255.0
c) For the Default Gatewaty enter in 192.168.1.1
d) For all of the rest of the settings, leave alone.
e) Press apply.
#8 Now go 192.168.1.1 with your web browser, and log-in.
To get back online, after you are done in the modem combo.
#1 Go back to Basic Settings.
#2 Enter in the info that you need to get back online.
c) And press apply in the router.

If you want to connect your computer to the modem, which the FAQ owner says would be easier and simplier.
#1 First in the Netgear disconnect from the net.
#2 Disconnect the cable that connects the modem from the Netgear router.
#3 Disconnect your computer from the Netgear router.
#4 Setup a Static IP on your computer.

Default Gateway: 192.168.1.1
#6 Connect your computer to the modem combo.
