...

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

iw dev wifi1.3 info

3.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.

4. 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)
logs files are generated under /tmp folder

5. Test the connectivity to EM-Controller through backhaul

ping 10.0.0.1 -c 5

Test the connectivity with wireless clients.

Extender2 (For Daisy-Chain )

1. Ensure Extender 1 is running properly with configured vap's of FH and BH.

2. Make atleast 7 feet distance from Ext1 to Ext2

3. Ensure ieee1905_em_agent,onewifi_em_agent processes are running in Ext2

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

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

iw dev wifi1.1.sta<i> info

7. Test the connectivity to EM-Controller through backhaul

ping 10.0.0.1 -c 5

Test the connectivity with wireless clients.
