Ditto, what SMS suggests seems logical, but when the router reboots, you'll still have to be logged in somehow either or...if the FW update failed, then PUs would still have to unplug the router, plug the computer and the router into a switch, then into the modem so you could remote in, as long as a VPN client existed on the machine, then you'll still be able to log back in to the router (probably) to troubleshoot and perhaps recover. If not, then they'll have to ship it to you via UPS/FedEx. As long as you're doing it for parents, and not hacking unethically, and if that were the case I'd have no idea, except to call the Maytag repairman
