We had 4.0 Spectum router and wifi. Was great in integrating our 4.0 security cameras. In no time we were being hacked. Spectrum tech. said upgrading to 5.0 was only solution. This upgrade outdated all security cameras but allowed us to monitor what was using our router through device management app. With in a few months they hacked the router and shut down device manager. Only option is replace equipment again.
