Comment 53 for bug 495981

Adding to comment 52. The frequencies of the access point are the same. In this example Channel 11. Is the networkmanager getting confused and makes it a connection to the incorrect access point? All evidence points in this direction. It explains also the wild changing of the signal strength.

A work around is to change the channel of you own access point to an unused channel. If there is one.
