My Samsung Network Extender has worked well for several years in the same location. We were away for two weeks, when we returned, all the indicator lights were solid purple. I noticed the remote GPS antenna had falling away from the window sill. I put it back, turned off the Network Extender and then my router. I turned the router back on, when ready, I turned the Network Extender back on. After a few minutes, all lights eventually went to solid blue (including the GPS), except the SYS light stayed flashing red. I waited 8 hours and it is still flashing red. Any idea what the problem is? Is it possible that the Network Extender registration with Verizon has been disabled?
