The document website (docs.gl-inet.com/en/3/) is updated almost every week. The PDF format which alzhao provided was maked manually, it should be a bit out of date.

  1. Prioritize online documentation
  2. If you want to read the document offline, please just save each page as .html format or .pdf format, it is very easy. This is the .pdf format (for GL-AR750S) I just saved. Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

Please google “how to save a website” or “how to save a website as pdf” or “how to read website offline”
