Connection broken when I move around among APs with the same ESSID but NM doesn't notice; dis- and re-enabling networking fixes it

[Vitaly Korolev]

The issue most frequently occures in my office where we have many wifi routers with the same name. Usually after I move to a different location in the building, the connection stay on for a while and at some point becomes unavailable. Although nm-applet is not aware of the issue and keeps showing that it's on. To get back on line I toggle the connectivity using nm-applet. A more reliable method of returning connectivity is a hardware switch for wifi which reinitializes it and allows me to connect. However I noticed that the problem will keep coming back intermmitently until I logout/login to unity.

My machine has Windows 7 on another partition and it keeps the wifi connection with no issues in the same building.

I noticed some pattern in system log. Usually when wifi becomes unavailable the following appears in the log:
