Well I did read that before. Unfortunately it is also confusing. It says to use .rar files if upgrading from firmware. In the directory there are .tar and .img files and no .rar files :slight_smile:

This does not answer my original question.

There is another directory without nand in it here:

http://www.gl-inet.com/firmware/ar300m/v1/

That also has .bin files - what are they? Can they be loaded on the AR300M ? Is there some AR300M that does not have nand?
