i always make sure when doing a power boot of a modem to first unplug the modem completely and leave it off for a minimum of one minute. this hels clear the cache inside the modem as well. (highly reccomended before resseting the modem itself.)

then once its ready power down your system.

then plug in modem let it do its thing then reboot your computer
this way it will make it Sync back up together.

have fun.

Usually if this happens all of a sudden it just needs a power boot on the modem. unless verizon fkd everything up
