Wifi adapter


I have purchased 2 wifi adapters from amazon. The recent one says compatible for Linux but then the manufacturer says only Ubuntu. Can someone please help me get wifi on my computer because soon I will not be able to use lan line anymore. If someone could refer me to a wifi adapter that would be helpful.

Thank you, Luca

Please provide additional info.
We need to know what your PC is, what wifi adapter you may have purchased, if you already have access to a wifi access point, what version of fedora you may be using, and as much other related info as you may be able to provide.
