Last night something interesting happened here at the house. The Actiontec RevI router decided to reset just the LAN DHCP back to default 192.168 Address. Even tho I use the 172.16 to avoid issues with vpn's into offices. All the computers that use DHCP somehow at the same time renew'd their leases at the same time. No other settings on the Router were touched. Earlier in the day did call to activate a new STB but I don't see how that would have reset the DHCP.
