I have been having quite a few problems with my Verizon Westell 6100 and my Airport Extreme Base Station. When I first tried to set up the new AEBS I got a double NAT error. Didn't think anything about it but was having connectivity issues on and off for the 2 weeks I had the AEBS. I contacted Verizon because I heard that I needed to put my Westell modem into bridge mode. I did that and no internet conneection at all. The Westell modem worked fine with my PC directly connected to it prior to the bridge mode change. But when I tried putting the Westell into bridge mode I have no internet on my PC. I tried adding in and setting up the AEBS thinking that maybe I needed it to automatically give me an ip address for my PC. No luck I still can't get an internet connection. I left the AEBS in DHCP but I was thinking that Verizon is using PPPoE. Could this be what is causing the problems? The Verizon folks actually helped me set up the Westell in bridge mode and I have tried a couple of other things posted on different web sites with no luck. I am about ready to throw the AEBS out the window. Any suggestions?
