Comment 41 for bug 1323089

I'm not Anne and I don't fully remember this "bug". I believe it was about
Linux looking for new WiFi routers to connect to every 2 minutes and
issuing a message when one was not found. This given there should be an
option within Ubuntu Network Manager (or whomever) to not message every 2
minutes when a new WiFi connection is not found.
