Test EM on BPI R4

...

Please ensure below processes are running in ctrl.

...

All configured VAPs should be UP and Running
VAPs should be broadcasting EasyMesh default SSIDs(eg, private_ssid, mesh_backhaul)

Extender1

Prerequisites - One Time Process

Delete the dnsmasq binary.

...

rm /usr/bin/dnsmasq

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

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

language	bash

ifconfig brlan0 10.0.0.215 netmask 255.255.255.0 up

15. Test the connectivity to EM-Controller through backhaul

Code Block

language	bash

ping 10.0.0.1 -c 5

10. Reboot the device

After reboot,

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

Code Block

language	bash

iw dev wifi0.1 info

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

Code Block

language	bash

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

language	bash

ifconfig brlan0 10.0.0.210 netmask 255.255.255.0 up

15. Test the connectivity to EM-Controller through backhaul

Code Block

language	bash

ping 10.0.0.1 -c 5

Test the connectivity with wireless clients.

Extender2 (For Star Topology)

Prerequisites - One Time Process

Delete the dnsmasq binary.

Code Block

language	bash

rm /usr/bin/dnsmasq

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

Code Block

language	bash

route del default gw
