Rob just moved and has a new cable provider. He works from home and has issues losing connectivity to his work using VPN. Leo says that the provider probably provides the modem. He should ask for DOCSIS III service. That will be more reliable and faster. Buying his own DOCSIS III modem will be newer and will save him money. Rob should ask them what DOCSIS III modems they support and buy his own. Another issue could be his router. Rebooting the router can clear out any bad issues. Routers do need to be replaced from time to time.
