When I connect my router to my modem, I cannot surf the net, nor can I access my router homepage. I have my modem in bridge mode, but I appear to have no connection.

You need to bridge mode your modem. And when set it to bridge mode already. Connect the dlink router. Access the gui of the router. Enter there your username and password. Powercycle modem, router and computer. Check connections. I f this didnt work, set again your modem to default, connect your router. Configure your router with username and password. Powercycle again. Check if it is working.

1. Use both the Modem and the router as NAT routers. Do this by making your router a DMZ node on your modem, that way ALL traffic will pass to the router, then set up port forwarding etc on the router.

2. Run the router/modem in bridge mode (recommended). You need to set the modem to run in bridge mode, check the user manual for refrences to bridging. Then set the router to connect to PPPoE using a username and password.

if you are using a dsl modem and a wirelss router

you will

1. put your modem to bridge mode to connect the router

2. change the ip address of your modem to connect the router

tell me if you need help for doing this, or you can also call your ISP, they do it too

I Think you ISP must be DSL.
Your internet is working with the old router when it is in bridge mode.
Check the IP address of your computer when it is connected directly to the modem and NOT in the bridge mode. Suppose the IP address is 192.168.X.Y. After that connect your computer to the ethernet port of the router. DO NOT connect the modem to the router. check the IP address of the computer again. Suppose the IP address of the computer is 192.168.A.B. Now make sure that both the IP addresses are not in the same range that means X is NOT equal to A. If they are same, then open the set up interface of your router and change the Local IP address of the router. that will help.

Hello there,

Your internet connection should be setup properly in order for the router to give connectivity to both your computer.

You must contact your ISP and ask them for the IP's and put it in the router.

I have been working on the same problem. I found information on the router settings on the USR website http://www.usr.com/support/8054/8054-ug/three.html but after the wizzard was run and PPoE setting was set to automatic (IP is Dynamic), it still doesn't work. I believe the modem needs to be set to bridge mode, instructions for this are on AT&T's website.
http://helpme.att.net/article.php?item=12197 Good Luck.

You could install Router Techs firmware on your modem www.routertech.org and it would give you the option to put the modem in full bridge mode. However I'm not sure the hardware on the modem fully supports it. You might have to use half bridge mode and let your router do the DHCP.

I had this same problem. I was going to go ahead and call ATT and ask them to put my modem into bridge mode, but I messed around a bit more....

I went ahead and turn on PPPoE...tried to run the set up again. Well it worked. Not the internet connection is working through the modem. For some reason, the setup changed PPPoE back to DHCP Client, but it's working now. Give this a shot before calling ATT if you like. Good luck.

One thing that isn't mentioned anywhere is the modem has to be in bridge mode. I was told this by a Linksys tech after doing all that was documented in the references article. I contacted my internet provider and they told me how to set the modem to bridge mode. This corrected the PPPoE error.

Symptoms * You have a new router, and cannot get online to the Internet. AND * The Setupwizard will detect dynamic IP even though you have a PPoE connection. (Going to router status on the administration page, there is a private IP address on Internet port. 192.168.x.x range.) Cause The SBC DSL modem SpeedStream 5100b, used on new DSL and Yahoo SBC DSL installations since Feb. 2004, causes the NETGEAR router Setup Wizards to fail, and prevents routers from connecting to the Internet. This problem affects many router brands. The modem can be distinguished from the earlier 5100 by a 5th light labeled "Internet". The SpeedStream 5100b's default configuration is "PPPoE on the Modem" ? matching a built-in PPPoE client convenience feature that sends login ID and password to SBC. To Work Around These Issues, Configure the Modem for Bridged Mode Note: In Bridge Mode you cannot to connect to the modem's configuration menu, except by resetting it as described below. 1. Disconnect the router from your network, and connect the computer directly to the SpeedStream modem 2. Open an Internet browser. 3. Type 192.168.0.1 in the browser address field and click Enter. The modem displays a configuration menu. 4. Click Advanced. 5. Enter the "Access Code" printed on the bottom of the modem. 6. Click PPP Location. The PPP Location screen appears. 7. Select Bridged Mode (PPPoE is Not Used). 8. Click Save Changes. 9. Connect the router between the computer and the modem. 10. Power off the modem. 11. Power off the computer. 12. Connect the Internet port of the NETGEAR router to the Ethernet port of the modem. 13. Connect the computer to a LAN port on the NETGEAR router. 14. Power on the modem and wait for 2 minutes. Don't go to the next step until this is finished. 15. Power on the router and wait for 1 minute. Don't go to the next step until this is finished. 16. Power on the computer. 17. Log in to the router by typing 192.168.0.1 in your browser. 18. When prompted, using lowercase letters, type admin for the user name, and password for the password.
