said by phil_z06 :Well, I didn't have any luck. I reset all hardware to default and started over. When that didn't work I reset the hardware again and followed the 3 steps above (including a and b) and that didn't work either. I then replaced the netgear with a non-managed switch (non-wireless and not a router). I still can't get to the Internet, so it has to be a setting on the Westell. I set up the bridged connection on the Westell, and I thought that maybe I could change the internal IP of the Westell to a 123.x address, but you can't change the internal IP. I called the phone company (cincinnati bell) and they were of no help at all. Anymore ideas?
I am not sure what you mean by "I set up the bridged connection on the Westell", but if you actually put the Westell "modem" into a true bridge mode (and do the PPPoE authentication in the Netgear router if your ISP requires PPPoE), you won't have to worry about assigning it a LAN IP address, because it will be invisible to your network, and it will pass the ISP's public IP address to the Netgear router's WAN interface. Besides that, you would not want the Westell's LAN interface to be in the same IP subnet as the Netgear router's LAN subnet anyway, because the Netgear router won't do any routing (meaning that it won't pass traffic between its LAN and WAN) if it's WAN and LAN interfaces are on the same IP subnet.
I suspect that your problem is that you really don't have the Westell "modem" in bridge mode, and unfortunately, the newer SBC inspired "modems" that AT&T is currently using do have major configuration limitations. You may have to buy a real bridge modem and use that instead of your current Westell "modem". I have had good luck in the past using a Zoom 5615 ADSL2(+) modem with AT&T ATM based aDSL service. However, if you have a U-verse branded AT&T IPDSLAM based DSL circuit (as opposed to a standard ATM based circuit), you will be stuck with using an AT&T supplied "modem", and trying to find a way to put it into true bridge mode.
Here is a screen shot (taken from the »
AT&T Midwest/Ameritech FAQ ) that shows how to put an AT&T/SBC supplied Westell 6100 into bridge mode (set it to "PPP is on the computer, gateway, or router" mode):

/r0/do ··· _ppp.pngUnfortunately, that information is somewhat dated, and the newer Westell modems may not have that exact setup page. And since you say that yours has a factory default LAN IP address of 192.168.200.1 (not a factory default value that is used by any AT&T supplied "modem" that I am familiar with), that would make it unlikely that you would find that exact setup page. However, you should be able to find something that accomplishes the same task.
