See this thread...

moved to 'For Developers' as you are dealing with master / snapshot

fyi... pppoe+dnsmasq+link-local logspam was reported @ r18915 and likely earlier

consider reporting:

I'm not an advanced user,honestly I don't know what I should change you can guide me ?

@oli Are you seeing actual issues with your PPPoE connection at this point? Or did you happen to look at the logs and spot the errors and wondered what was happening?

As for the nlbwmon error, see this GitHub issue.

I only saw the errors and I wondered if everything was fine, the internet works without problems!

Do not use snapshots if...

  • your expectation is to have a flawless and 100% working compilation, installation and usage of the firmware. Snapshots are experimental, and weird issues of any kind can arise at any time

Do use snapshots if...

  • you are experienced with linux and know how to manage unexpected problems of any kind

Yes, I know this, I just wanted to report that the problem persists..
