I heard that there was going to be a new TV-Box with WiFi in April 2014?!?

We have several WiFi devices in use in our household. 4 iPhone, 1 iPad, 1 iPod, 1 Mac Book Pro, 1 Mac Book, 1 Mac Book Air, 2 Apple TV, 1 Netatmo weather station. Plus 2 Swisscom TV boxes, 2 Windows PCs.
Modem: Swisscom Centro Grande. WiFi via Apple Time Capsule.
After restarting the modem, a few devices always work, but never all! Every time you restart it’s a different one. It also happens that the devices initially have WiFi, but later no longer:
Guess: Problems with IP address distribution.
