Re: Electricity went off. Lost internet connectivity to network. SWM system.
Sometimes, when a power outage occurs and then resumes, the Directv system seeks a Network connection. If the router has completed boot up, all is well. If the router has not completed boot up, the Directv system will configure itself without a network connection to the router.
If this is your problem, the cure is to disconnect AC power from the Directv boxes and then reconnect AC, first to the Genie, then the HD DVRs, then the receivers. If you have a Wi-Fi connection between the Directv and the router, the process may be somewhat different so post back details.
