WR31 firmware versions previous than 5.2.14.3 only offered access to GPIO settings from the WR31 CLI (Command-Line Interface). GPIO settings were added to the WR31 web interface in Traversion 5.2.14.3 firmware.
In order to access GPIO settings from the WR31 web interface, ensure that the WR31 is running firmware version 5.2.14.3 or newer.
