I'm using vr1600 now, but its signal is too poor. The NBN network is located in a corner of my house, and my wifi signal can only cover two rooms. When I use wifi in the bedroom at the other end of the house, I get stuck while watching YouTube videos. The wifi drops out when in the kitchen. I think I need a better modem.
The standard modem/router can only cover a certain distance at clear site. If there's any walls in between, then you'll experience the same thing.
To make sure that the WiFi coverage is strong on your premises, then you need an access point or mesh network.
