  • Solid yellow - Limited connection to the wired network
  • Solid red - Low wired network speed
  • Green light - X5 position is correct
  • Solid yellow - X5 is far from router
  • Solid red - X5 too far from router

Successful pairing of the devices will result in a glowing LED representing the quality of the connection between one device and the other (ideally it should be lit solid green, then the quality of the connection is the best).


We started our tests by verifying the maximum speed performance of the LAN and iperf3 server. The device was connected to a 10/100/1000Mbps network card to a switch. We obtained the following maximum speeds for a single TCP stream: download 894Mbps, upload 958Mbps. Access points in the network were connected with each other in mesh mode only, i.e. wirelessly. The boot process ran without any problems.

We made thesignal map using AirSurvey software. For correct reading of the signal levels, please pay attention to the color legend at the bottom of the picture. The devices distributed on the ground floor have been marked with icons corresponding to their appearance. The Arris X5 access point in measurement point 1 has been connected to the switch via 1Gbps Ethernet port.
