回复：拔掉电源，然后再接上。。。

That one I did, still not working.
Second one I do not fully understand. Where do I find IP setting in gmail? Or Google Voice? Thanks again in advance if you can help more.

I also email to OBI support. But they say to put it in DMZ and try again. But Verizon MI424WR router only has a DMZ enable check which is asking for a IP. But I don't where to locate OBI100 IP address. Can anyone help?

Thanks.
