Well, a tech called after 1+ days about my problems with putting the gizmo on the modem, and getting echoes. Echoes seemed to have disappeared "by themselves", so this may not be a problem with the gizmo after all. He said some modems do not give up a DHCP address to the gizmo easily, especially after a router was hooked up to it... He suggested MAC spoofing, which I have yet to try. He said in his own private configuration, he has the gizmo on his LAN, because the gizmo's handling of port forwarding, etc. is rather dismal. So there you have it. For the people who suggested the 45 minute waiting time, you presume the gizmo ALREADY HAD a DHCP address - I've never seen it get one before in my setup. What you probably need to do is disconnect the MODEM, and let it leak out the charge - by doing that to the gizmo, you were solving the wrong problem, and probably got lucky that the gizmo got re-DHCPd.
lol...
gibster, you're very intent on proving someone wrong aren't you..?
I am really tired of explaining how this works so I'll let you believe whatever you think is right. I guess I presumed that you would have tried reseting your modem after letting the gizmo discharge and reconnecting it. My fault then, I was wrong, there you go.
You said you made phone calls using your VoIP service, so obviously your gizmo had obtained an IP from your router's DHCP tables. When your gizmo obtained this IP, it "married" itself to it until the given DHCP lease time was up. Same as your computer, wireless access point, etc that are hooked up to your router. The only difference is that the gizmo doesn't have a software or hardware reset to release/renew the DHCP lease it obtains. So, yes, you do need to power cycle/discharge it for it to make a new DHCP request. As for your cable modem, some don't care if you switch devices on them.. some do. For the ones that do, they are just specifying that they will only communicate with a specific MAC device. In your case, it sounds like your router. So when you pwr cycle the cable modem, it "should" be open to communicate with a different MAC device (now the gizmo). I would really feel sorry for you if you need to clone the MAC address of your router to hook up your gizmo.
