Without being too technical, the problem - as we all know - is that the ISPs sell us are cheap WiFi router boxes...
The signal is too weak to go through brick walls, without losing a lot of speed. They can't handle lots of devices or heavy use either.
As a result, you are left with weak WiFi and dreaded 'wifi dead spots' in your home...
But, plug a Wifi UltraBoost device into any socket, and that all soon changes.
Wifi UltraBoost is essentially a powerful amplifier and signal extender, all in one tiny box.
It works by receiving your existing WiFi signal, boosting it, and then transmitting the super-amplified Wi-Fi through anything; concrete walls, multiple floors and steel beam - no problem!
In a nutshell: You get WAY faster and stronger internet. Even during peak times, and even in previous 'WiFi dead spots' around your home.
