Trying to connect to a Reticulum transport node (and some edge nodes) on a local wi-fi

Essentially, I’m the only one running Qubes in this room right now, and I am the only one who isn’t able to connect to a router that has a Reticulum transport node connected to it. I’m trying to grasp how Reticulum works, but it seems this comment on interfaces in the config file for Reticulum might be relevant: “This interface enables communication with other link-local Reticulum nodes over UDP. It does not need any functional IP infrastructure like routers or DHCP servers, but will require that at least link-local IPv6 is enabled in your operating system, which should be enabled by default in almost any OS.”

I’m not sure if link-local IPv6 is enabled in THIS operating system, never mind whether I would need to enable it in my app qube I’m using for Reticulum, or somewhere else in the system.

Any advice appreciated.
