Q2:
Could I setup wired connection between AiMesh routers (Ethernet
backhaul)?
A: Yes. AiMesh system supports both wireless and wired connection
between AiMesh router and node to maximize throughput and stability.
AiMesh analyzes the wireless signal strength for each frequency band
available, and then determines automatically whether a wireless or wired
connection is best to serve as the inter-router connection backbone.
Follow the setup steps to establish a connection between the AiMesh
1
router and node via WiFi first.
Place the node in the ideal locations for best coverage. Run an
2
Ethernet cable from the LAN port of the AiMesh router to the LAN port
of AiMesh node.
AiMesh system will auto-select the best path for data transmission,

whether wired or wireless.
