When I go to clients I see the correct devices that are on the network.   When I go to HomeCare > Parental Controls > Select a Profile > Click Devices> Click + to add a device I see new unknown devices.  I don't recognize these devices not sure what they are.  These are not supposed to be on the network.  Over time more unknown devices keep adding they all have different Mac addresses ( I don't see them on the clients tab but just in parental control).  The only way to get rid of these devices is to do a factory restore and set the router from scratch but as time progresses the unknown devices slowly start to show up.  It had gotten to a point where there were 10 of these unknown devices at one point.  Is there anything I can do about these?
