Ubiquiti introduces five new routers for the EdgeMAX® platform:

  • EdgeRouter™ 12P
  • EdgeRouter 12

  • EdgeRouter 4


They join the array of cost-effective Gigabit routers:

  • 8-Port EdgeRouter Pro
  • 8-Port EdgeRouter
  • 5-Port EdgeRouter PoE
  • 3-Port EdgeRouter Lite


High Performance

The EdgeRouters offers superior routing combined with top price/performance value for your routing applications.

The EdgeRouter 4, 6P, 12, and 12P are each capable of routing up to 3.4 million packets per second.

The 8-Port EdgeRouter and EdgeRouter Pro route up to 2 million+ packets per second, while the EdgeRouter Lite and EdgeRouter PoE route up to 1 million packets per second.

PoE Flexibility

The EdgeRouter 6P, PoE, and 12P include configurable PoE ports to power airMAX® products, and the EdgeRouter 12 has a PoE input port and a PoE passthrough port.

Fiber Connectivity

The EdgeRouter 4 and EdgeRouter 6P provide an SFP port. The EdgeRouter 12 and 12P feature dual SFP ports, while the 8-Port EdgeRouter offers two combination RJ45/SFP ports.
