There are various resources out there, from the official Ubuntu Documentation to many forum topics and Askubuntu questions, all seeking to answer the same question: which adapters work with Ubuntu? But, as is usual in such situations, much of the existing material is messy and/or outdated.
I'd like to know which ones work with Ubuntu 11.10 specifically -- the latest, "out of the box" version, with no kernel modifications or additional drivers to manually mess with. I believe that this will be a very useful resource when deciding to buy an adapter.
