problem using router for my sbc dsl

3590 Views 9 Replies 5 Participants Last post by  johnwill
I just signed up with sbc dsl. They sent me 2wire 1070 modem. I installed it using CD it came with. Everything worked fine. Since I wanted to share the connection with my roommate, I bought D-Link router as suggested by a salesperson at computer store. I connected modem to router's wan port, and router's lan port to computer. Now I don't get any internet connection. SBC Self Help comes up telling me that modem needs to be connected to computer directly. Is there any way around this? Thanks. :4-dontkno

You have to configure your router to authenticate with SBC, unless the 2wire modem does NAT then all you need is a switch.
Thanks for your reply. I am lost. How do I authenticate?
You don't need any athentication, the 2WIRE 1070 has NAT translation, and you obviously already have that working. Try this:

Connecting two SOHO broadband routers together.

Configure the IP address of the secondary router to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses through, I'd assign the secondary router as it's IP address.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!
Your DSL modem may?? need to be put into bridge mode.

Before you go try to change the DSL modem to bridge more, try connecting the router, configure it for PPP/PPPoE, enter your SBC provided account/e-mail address and password. Select keep connection alive/keep alive if you see it. Save the router configuration.

Power off the router, computer and DSL modem. Power up the DSL modem until the DSL/Link LED is solid (2-3 minutes), power up the router (wait 2-3 minutes), power up your PC and see if you get connected.

Re: problem with router using sbc dsl

Hey there: just know that if you bridge the router that SBC won't touch it you will be referred to the router's if you have any questions for SBC call them before bridging it... :smile:
They already have a working router, the 2Wire, there's no point in tinkering with bridging anyway.
I would return the router and purchase a switch instead.
No need to return the router and buy a Ethernet switch, as the router can be used as an Ethernet switch if needed. Just turn DHCP off on the router and only connect the LAN ports, leave the WAN port disconnected, and you have an Ethernet switch!

This also assumes the DSL modem supports and is configured for routing, some do, some don't. I assume in the current configuration the DSL modem may be configured to PPPoE, I have not researched the specific DSL modem we are working with here, yet.

Right, that's why I suggested it in post #4. :smile:
