Google has produced its second-generation OnHub router, just two months after it unveiled the first version. Switching from TP-Link to Asus, the new OnHub retains the same core functionality as its predecessor, but this time the physical design has changed, switching out the cylindrical casing for one with a slight taper, along with a new "Wave Control" function that will boost the Wi-Fi speed for a specific device, triggered by a wave of a hand above the router.
