This NetReset NR-1000US Power Source works with any modem and router and resolves networking issues by offering sequential power cycling. If you experience power loss, NetReset will properly bring the network up when power is restored by performing NPS (Network Power Sequence). NetReset will first power up the modem, and then apply power to the router one minute later. NPS will also be performed on initial setup, and every 24 hours at a specified time programmed by you on a regular day by day basis. If NetReset is returned with original receipt, and was operated under normal conditions by the original purchaser, it comes with a one year warranty from the date of purchase. NetReset was created by BC Designs LLC, a company known for installing security systems, home automation, custom audio/video setups, and video surveillance. This company created NetReset to fill its needs for constant Internet and Internet connectivity not only to keep their own business running, but yours as well.
