^^^Have you tried turning on your Verizon Wireless router and configuring it? Just because it worked for a day on your access point doesn't mean it will consistently work that way.
It should though. Electronics don't just randomly "decide" to work or not; they do things for a reason. Unless something is specifically changed, it absolutely should consistently work that way.
I have no plans to use the VZW router, it's nowhere near as good as the AP I use. So I guess I'll try restarting the STB, and if that doesn't work, so be it.
