After replacing my adapter (with an identical model), the drop after a few minutes and other problems originally reported went away. So, I guess, that's what I'd recommend, too.
However, I still have problems with high ping times. The "solution" to that is to disable power management in the iwlwifi driver. When I asked why Dell ships an Ubuntu laptop with a wireless adapter known to have issues, the reply was along the lines of: to earn the "Ultrabook" moniker it must ship with a Centrino adapter.
