Windows 7: Router DHCP IP Range Question

Router DHCP IP Range Question

I am trying to use a Netgear WNR3500 wireless as a wireless access point on my network.

I have attached two screenshots from the main 2WIRE AT&T U-Verse wireless router. I am trying to determine the DHCP IP range of the 2WIRE AT&T router.

Screenshot #1 shows Status under the LAN tab: Private Network DHCP Info -

Screenshot #2 shows DHCP under the LAN tab: DHCP Network Range - (default)

Can someone please tell me which DHCP IP range I should use. I need to set the IP address of the Netgear router to an IP outside the DHCP range.

Thanks! Bill

1) You can leave the 2WIRE settings alone.
2) Connect to the Netgear WNR3500
3) Disable DHCP
4) Connect the WNR3500 and the 2WIRE as shown in step 4 on this website:

Where that image shows a wall jack...
...that would be one of the ports on your 2WIRE router.

And of course you can use Wi-Fi instead of a LAN cable to connect the computer to the WNR3500 for day to day surfing, but you might not be able to configure the WNR3500 via that connection. More on that later.

The 2WIRE router will issue all of the IP addresses for your network. Once you connect to the WNR3500 via Wi-Fi, your connection will be forwarded to the 2WIRE for it to hand out an IP address.

To answer your question more directly, the DHCP IP Range is shown in screenshot #1. Screenshot #2 is showing the starting IP and a thing called a submask ( That does define the starting and ending numbers for a network, but it is not the same thing as the range of IP addresses that the DHCP service will dole out.

>> I need to set the IP address of the Netgear router to an IP outside the DHCP range.
Some 2WIRE routers will not accept traffic from an IP address that are outside of the DHCP range unless you also set some things up in the router for that IP. So once you get this all hooked up, you might not be able to "surf" to the WNR3500's configuration interface. Also, you might need to look around in the 2WIRE interface to see what IP addresses are already in use by things like DVRs.

One way to avoid all of the mess mentioned in the preceding paragraph is to assign the WNR3500 an IP address of And when you want to change settings on the WNR3500, assign a static IP address to the hard wire network adapter (Local Area Connection) on your computer:
...a static IP address of
...a subnet mask of
...and a gateway of
Then plug a LAN cable from that computer into one of the LAN jacks on that router (not the internet jack). Surf to

Windows 7 Ult, Windows 8.1 Pro,

Actually a DHCP assigned IP will usually work fine for the secondary router.

I use DHCP for my A/P with no problems at all. Mine is a dedicated A/P so the set up is much easier than a regular router.

Change the LAN IP of the AP from its default so that it lies within the subnet of the primary router but preferably outside the dynamic LAN IP range of the primary router. (examples below) Note: This is not a requirement, but keeping everything in the same IP range can make administration and file sharing easier.

In fact for this network I would install the WNR-3500 first since it's a superior router and use the 2wire as the secondary A/P.

Disable DHCP on the 2Wire and plug into a LAN port on the 3500, set up the wireless security on both routers, you can use the same SSID to auto connect between different area's, nothing else should be required.

This link explains the process pretty well and shows other settings that may help. :)
