We've been having an issue for the last few weeks with the VTv dropping in and out. So, we did a little experiment. We turned off all devices, all except the VTv. We contacted Vodafone and we were told that we had too many devices connected. Not sure how when we had turned everything that was wireless, off. And it still dropped in and out!
Our system is not connected by ethernet but by a vodafone extender and one is connected to the hub. I have wasted so much time on this stoopid system. I am over it. . I just want a sysytem that works.
