Which IPK file for GL.iNet GL-AR300M16-Ext Easytether?

I want to use Easytether on my GL.iNet GL-AR300M16-Ext but don’t know what IPK file to use. Also do I use openwrt 19.07.3? Thank you!

On my GL-AR300M16, I use


I do not work for and I do not have formal association with GL.iNet

Thank you, Did you update to latest firmware or used the stock one?

My router still has Firmware 3.203-0701 because I do not use it much anymore. It should be safe to upgrade to the latest firmware and you can reinstall an older version if necessary.
