Any always-on wifi device, such as a security system, connected to the Eco 100 router will keep the router’s wifi active, so it will not be able to go into the Full Eco standby mode. In this case, you will see the device listed as ‘Connected now’ in the registration list in the router’s settings menu. Even when wifi is active, the Eco router still offers a 90% reduced pulse frequency. However, we strongly recommend that, if possible, you install wired alternatives or ones that are not connected via wifi.
