10. Reboot the device
After reboot,
2. Edit the AL_MAC_ADDR in /nvram/EasymeshCfg.json. Here, wifi0.1 interface mac address as AL_MAC_ADDR
3. Reboot the device
After reboot,
411. Ensure mesh backhaul connectivity is established over 2.4G through wifi0.1 interface.
Code Block | ||
---|---|---|
| ||
iw dev wifi0.1 info |
125. Verify mesh backhaul connection in Extender1 side as well.
Code Block | ||
---|---|---|
| ||
iw dev wifi0.1.sta<i> info iw dev wifi0.1.sta<i> station dump ## This command gives information on connected client ie Extender2. |
136. Wait for few minutes( for Agent to propagate SSID information from Controller to OneWifi in Extender2) and then check
147. Set static IP for brlan0 interface in Extender2
Code Block | ||
---|---|---|

ifconfig brlan0 10.0.0.210 netmask 255.255.255.0 up |
158. Test the connectivity to EM-Controller through backhaul
...
Test the connectivity with wireless clients.
