This is a longstanding bug in either the kernel or babel on correctly determining the channel on a wireless device in AP mode. It is not an error, per se, it just means that diversity routing (which needs to know the channel) doesn't work as well, as the channel here gets set to "interfering" rather than the correct channel number. > > I'm trying to remember why I even want babeld running.
