@i7bar Thank you.
As I know nothing about this issue, could you recommend a configuration for the GL.iNet GL-MT1300 router? Or could you link to resources that might help?
edit: I suppose this thread helps: Change outgoing TTL - #23 by Teth123 .
I’m not entirely sure how to apply this to repeater mode, even with the firmware version of 3.215. I guess I setup some advanced firewall rules, and that the TTL interface only otherwise applies to the “modem” mode.
