WiFi GW Updating

Once update is complete:

  • It should reconnect to the Internet then restore the AP update page.
  • Some wireless networks have issues using the internal 192.168.4.1 address. If your Gateway Shows updates even after doing an update, try using the local WLAN IP address to do the update.

Manual updates using Windows

If you have an issue with Over-The-Air updates, or you want to load an older version, you can update the Gateway Manually. The firmware versions are listed at the bottom.

1. Connecting the Gateway to a computer

The FT232RL FTDI USB 3.3V/5.5V module is one option to connect the WIFI Gateway to the computer. You need to set jumper to 3.3V or you could damage the Gateway. You can plug the

Its generally a good idea to reset the device using the Reset on the Login Details screen. Sometimes when we add new code we use different parts of the device memory so you may see erratic data displayed on the config screens. Resetting the device will reset the memory on the device to work with the new version. If the config screens are not visible you can also reset the device using the URL : http://192.168.4.1/reset
