State of WLAN Support on Linux?

ntropic asks: "I/ve recently bought a Belkin 802.11G USB adapter and was dismayed to find, after a few hours of struggling with it, that there seems to be no one who has managed to get it working under Linux. During the search for clues, it seemed that sum total of Linux support for wireless networking are the linux-wlan project, and the linuxant wrappers for Windows drivers. The former seems to support only Prism chipsets while the latter is a commercial solution, albeit quite an inexpensive one. Is that all, or are there better sources for wireless networking support?"
