Comment 13 for bug 158481

Misoldgit, please file a new bug instead of adding information here. What you're seeing is most likely a totally different issue.

FWIW, I've been running NM in wifi only with IPv6 set to Automatic for the past few days with no issues at all; and previously for a few months with both wired and wifi with IPv6 enabled and "Automatic", with no issues either. I'll set this back to Invalid because IPv6 does not appear to cause an issue with wireless itself and because this bug was filed a long time ago, when NM didn't even really support IPv6 so much.

If you're still seeing issues, please don't hesitate to file a new, separate bug so that it can be looked into. The easiest way to do this is with the command: "ubuntu-bug network-manager"
