You could also probably just restart the cable or FIOS modem or your router if you have one. It depends how you connect, for example, I have a cable modem that goes to a router, so if there was ISP connectivity issues, I would at the modem first.
oh its surely the ispJust a guess but it's possible your firewall rules are blocking DHCP requests and responses. Typically a DHCP lease is set to an hour or so. After half that time it will try to re-register. If that fails it will try again at 3/4 of the time. If this all fails the IP address is released when the lease expires, i.e. you lose your IP address and as a consequence your connection.
