GL-MT300N-V2 Automated Wifi Toggle for IOT Testing

Device setup (optional)

1. Do whatever you'd normally do to set up a router- set the SSID, password, etc.

Script setup

1. Plug in power to your device
2. Connect your laptop or phone to the default SSID using the SSID/Password listed on the label on the back of the router.
3. SSH to 192.168.8.1 as user root (default password is goodlife). For example, from Mac or Linux:

# ssh root@192.168.8.1

4. Edit a new file at /sbin/wifi_toggle (using vi or similar)
5. Paste in the script
6. Save!
7. Give the script executable permissions:

# chmod +x /sbin/wifi_toggle

Cron setup

1. Click the advanced interface link in the upper right
2. Sign in to the advanced interface as user root (default password: goodlife)
3. Go to System > Scheduled Tasks
4. Enter */3 * * * * /sbin/wifi_toggle and save
   Adjust this cron string to change the timing, e.g. */10 * * * * /sbin/wifi_toggle would toggle every 10 minutes.
5. Go to System > Reboot to reboot the router
6. Your device should reboot and start cycling wifi on/off!

Notes

• This is based on the wifi toggle script here, but avoids manually changing the lights. The device seems to already be watching wifi state and the lights update automatically.
• This should work on any OpenWRT/LEDE compatible router, but you may need to change the device variable in the wifi_toggle script. Here's an example of how to find it on the GL-MT300N-V2 (its wireless device name is mt7628).

# uci show | grep wifi-device
wireless.mt7628=wifi-device

Note: your device may have more than one wireless device.

• For other devices, you may or may not need to manually update the wifi lights as shown here. The GL-MT300N-V2 doesn't seem to need it.
