Hi,
Thank you very much for your love and attention to GLiNet products.
Let us talk to depend on the GL firmware itself without third-party plugins:
- IMEI not changes automatically
- Support BSSID andWAN MAC randomization
- I assume it does not support.
There is no doubt that recommended to install the latest firmware.
You can consult the author of the plugin to whether it is suitable for the v4.3.26 firmware. Of course, you can try installing it in v4.3.26 first, and then consult the author if you have any questions.
