Well, the internet router can't get IP from main fios box. Happens periodicaly. The "solution" is to call fios tech support and ask then to reset/reboot the main fios box in a way that phone,internet & tv are disabled for at least 30seconds.
Its very weird problem to me because 3 times in arow this happened right around the midnight. Also, once I noticed the 'no IP problem' at the end of the day but was wasn't in the mood to speak with verizon, got up in the moring prepearing to call verion but internet was suddenly working.
