GL-MT300N-V2 Automated Wifi Toggle for IOT Testing

Script setup

1. Connect to your GL-MT300N router's Wifi network
2. go to 192.168.8.1 and perform initial setup including setting a password for admin/ssh access
3. under internet setup, add a "repeater" wifi to make the GL-MT300N bridge to a functional wifi network.
4. ssh into router and use password setup above.

ssh root@192.168.8.1

5. Edit a new file at setup.sh (using vi or similar)
6. Paste in the script
7. Save!
8. Give the script executable permissions:

chmod +x setup.sh

9. Run the script

./setup.sh

10. You will be asked how many minutes you want the on/off interval to set at. Enter 10 or your preferred value
11. Slide switch on side away from and back to your preferred setting.

Switch modes

1. Left :: standard access point, Wifi stays on if powered on. (Center LED is off)
2. Right :: Wifi toggles on/off at designated interval (Center LED is on)
