I wanti to hook a linksys router to my 2wire modem/router (2701HG-b) to share the connection. I ran from an open port from the 2wire to the WAN port of the linksys but it will not work. I did this before with my cable modem to a router to my linksys router. It worked then but not now. I read I can turn the 2 wire into a modem only but I need the 2wire wireless access also. IPCONFIG /ALL sees the 2wire with IP info as well as dhcp server/gateway. Any ideas?

Do you want to use the 2wire as just a DSL modem or as your firewall/router? Its default configuration is as a firewall/router. If you want to use the 2wire as a passthrough-only DSL modem, you'll need to look up instructions on bridging it and have only the Linksys plugged into it. The 2wire will not be providing wireless, etc., it'll just be acting to translate from DSL to Ethernet (Bridging)
If you're happy with the 2wire as your firewall/router but want to use the Linksys as an access point (providing wireless signal in another area, perhaps), the setup is actually much simpler.

Try resetting your Linksys router, you may have configured it for the cable specifically (with a fixed IP address). Unplug any computers or other devices from the 2wire (except the router) and power cycle the 2wire. Make sure you have the 2wire ethernet going to the linksys WAN port (or just one of the ethernet ports if you want the 2wire to do all of the routing, in which case you'll need to turn dhcp and routing off in the linksys). Connect to the linsys router and configure it if necessary. The 2wire modem could also be setup to only give out one IP, or only to a specific MAC address. Which is where the disconnecting comes in, in my statement above. It also appears that the 2wire router you have, has a USB port, some routers do not work well (or at all) with both the USB port and ethernet ports in use. | |||

if it works on your computer, then there is no reason why it shouldn't work on the Linksys' WAN port. maybe your old cable modem was using a static IP address instead of DHCP. make sure to configure the Linksys router's WAN IP settings the same way you're computer is set up. | |||||||

I don't specifically have that model 2Wire model, but I have the 3700HG-V (used in AT&T U-Verse setups). The 2wire Homeportal units seem to detect and know when you're double-NATing (as the Homeportal has a router and Wi-FI AP built-in and your Linksys is one as well) and either warn you about the setup or flat out refuse to work. I'm not sure if your unit has this, but setup your Linksys as Tyler instructed -- and head to the router's admin page (http://192.168.1.254 for me) and look for an option called DMZplus. This option passes your 2wire's external IP address to a MAC address of your choice (your Linksys router's WAN-side MAC address in this ase) -- so your Linksys router behaves as if it's attached directly without a router in between like your previous cable modem setup. (Technically, it's a layer 3 bridge that passes all incoming traffic to the assigned DMZplus host -- so it's not exactly like a direct modem connection, but pretty close) This page will also let you control which of the attached devices get which IP (in your case, just the router's WAN-side should be attached to a LAN-side port on the Homeportal). See if that helps! EDIT : I missed the part where you said you needed the Homeportal's Wi-Fi capabilities -- in this case you could disable DHCP on your Linksys unit and not attach anything to the WAN port. This way, you can use your Linksys unit as a plain switch to attach multiple computers using the Homeportal's router capability. You can also just use the Homeportal as-is since it features four LAN-facing ports. | ||||

Network Configuration of 2Wire Gateway plus Wireless RouterI have a network set up with a 2Wire 1800HG Gateway and a LinkSys WRT350N Wireless Router.
This is set up as two network addresses, 192.168.1.0 and 192.168.2.0 (two Class C networks). Computers on both networks can access the internet through the 1800HG Gateway. ================================================================================== The 2Wire 1800HG is used with its default IP of 192.168.1.254 and creates the first network. You get to the hard core 2Wire 1800HG/2701HG Gateway configuration pages by using this URL: http://192.168.1.254/mdc. 2Wire 1800HG SettingsBroadband Link Local Network Configure Firewall Advanced LinkSys WRT350N settingsThe WRT350N WAN port is set to an IP of 192.168.1.253. Internet Setup The WRT350N network address is set to 192.168.2.1. Network Setup Basic Wireless Settings Wireless Security Security VPN Passthrough Administration (Remote Management is disabled for both the 1800HG and the WRT350N). This also worked on an older LinkSys wireless router, the BEFSR41. All wired computers are connected to the WRT350N Gigabit LAN ports either directly or through Gigabit switches. | |||||||||||||

Cascading Routers, Connecting 2Wire Gateway to LinkSys Wireless RoutersSince my original answer got long with the settings, I've tried to make this post an overview answer to Simon's question. Hopefully this will make it less confusing. In general, you want to look for articles about Cascading Routers. Here are 3 good ones with the core of each in summaries: Cascading (Connecting) a Linksys router to another router There are two ways to cascade a Linksys router to another Linksys router:
This connection makes the computers connected to both routers to be on the same LAN IP segment. This will allow sharing of resources within the network. For instructions, click here.
This connection makes it easier to identify which router the computers are connected to since they will have different LAN IP segments. For instructions, click here. NOTE: If you have a modem/router from your Internet Service Provider (ISP), you can still do cascading of routers. http://www.corenetworkz.com/2009/05/how-to-connect-three-routers-in-your.html How to connect three routers in your network - Three Router cascading To connect three routers in a network with full routing features we need to change the third octet IP address of the routers ( In this IP address 192.168.1.5 the third octet is 1 ). Many guys telling like it is difficult to connect multiple routers in a network. But following the guide below it will be a fun. To perform this follow the steps provided below. http://www.corenetworkz.com/2008/02/router-to-router-cascading-simple-guide.html Router to router cascading a simple guide There are two ways to cascade a router to another router: I used the LAN-to-WAN connection. Computers on both networks can access the internet through the 1800HG Gateway. Both of the wireless networks are active and use different SSIDs. I can access both the 2Wire 1800HG Gateway and the LinkSys WRT350N Wireless Router easily from any computer on the 192.168.2.0 network. I have the wireless on the 1800HG set for SSID #1 and the default WEP 64-bit for ease of access for guests, and the wireless on the WRT350N is SSID #2 and will be set to WPA PSK2 Personal when I finally get rid of the last WEP device. :) | |||
