386.3_2 upnp minor issue bug?

[Laxarus]

Hey guys, we have been trying to figure out an issue with the Home Assistant folks regarding the upnp behavior of an Asus router running merlin fw.

It is likely that this issue is a bug of merlin fw upnp.

The details regarding it can be found in the issue tracker of the Home Assistant.

Upnp decoding error when no Internet connection · Issue #55783 · home-assistant/core

The problem When my modem loses the internet connection, I am getting these errors for the upnp. I have a asus router running merlin fw 386.3_2. Modem is behind the rotuer in dsl bridge mode. Upnp ...

Basically when the internet connection is down, the router gives inexplicable upnp response like this.

<NewExternalIPAddress>schemas.upnp.org��i����</NewExternalIPAddress>

The router is RT-AC5300 with merlin fw 386.3_2.

Any input is appreciated.

Hey, @RMerlin did you check that out or have any suggestion? Appreciate, the input.

I didn`t. I'm not the miniupnpd developer, so I don't do any debugging for it.

Hmm, ok thank you. Do you mind if I ask how to manually update the miniupnpd on the router without breaking anything to check if the newer 2.2.3 version fixes the issue?

You can't update individual parts of the firmware, it's not designed for that. However, there is a miniupnpd package in Entware so maybe you can disable the firmware version and use that instead.

thanks @ColinTaylor, I think it is beyond me to arrange such a setup since I have to disable the builtin one and make it work nicely with Home Assistant. I don't want to risk breaking any stuff on the router that is working fine other than this tiny issue.

Where's your sense of fun? breaking things, and then spending a weekend fixing them is the best imho.
