10. Reboot the device

After reboot,

11.Ensure mesh backhaul connectivity is established over 5G through wifi1.1 interface.

...

iw dev wifi1.1 info

12. Verify mesh backhaul connection in EM-Contrller side as well.

...

iw dev wifi1.1.sta<i> info
iw dev wifi1.1.sta<i> station dump ## This command gives information on connected client ie Extender1.

13. Wait for few minutes( for Agent to propagate SSID information from Controller to OneWifi in Extender1) and then check

  • Check all configured VAPs should be up and running with "iw dev" command
  • VAPs should be broadcasting default EasyMesh SSIDS (ie private_ssid, mesh_backhaul)

14. Set static IP for brlan0 interface in Extender1

Code Block
languagebash
ifconfig brlan0 10.0.0.215 netmask 255.255.255.0 up

15. Test the connectivity to EM-Controller through backhaul

10. Reboot the device

After reboot,

11. Ensure mesh backhaul connectivity is established over 2.4G through wifi0.1 interface.

Code Block
languagebash
iw dev wifi0.1 info

12. Verify mesh backhaul connection in Extender1 side as well.

Code Block
languagebash
iw dev wifi0.1.sta<i> info
iw dev wifi0.1.sta<i> station dump ## This command gives information on connected client ie Extender2.

13. Wait for few minutes( for Agent to propagate SSID information from Controller to OneWifi in Extender2) and then check

  • Check all configured VAPs should be up and running with "iw dev" command
  • VAPs should be broadcasting default EasyMesh SSIDS (ie private_ssid, mesh_backhaul)

14. Set static IP for brlan0 interface in Extender2

Code Block
languagebash
ifconfig brlan0 10.0.0.210 netmask 255.255.255.0 up

15. Test the connectivity to EM-Controller through backhaul

Code Block
languagebash
ping 10.0.0.1 -c 5

Test the connectivity with wireless clients.

Extender2 (For Star Topology)

Prerequisites - One Time Process

  1. Delete the dnsmasq binary.
Code Block
languagebash
rm /usr/bin/dnsmasq

2. Remove default gw entry from routing table since WAN access will be through backhaul connection.

Code Block
languagebash
route del default gw
