Since installation we have had downtime sceduled for three devices.  recently one of the devices loses its ability to connect even when the downtime is not for a fewmore hours,have reset modem,device, forgot networkand signed back in still not able to connect.  Theo ly way he can connectis have no downtime scedule which doesnt work.  the other two devices work fine its just the one,and that one need the scedule the most, anyone else experience this?
