http://www.linuxquestions.org – I am using Xubuntu distribution, and just installed the SMCWUSB-N2 wireless adapter in a Compaq desktop (around year 2000). The adapter is recognised and starts working fine with the "default" (built-in) Xubuntu driver, but after 2 to 4 minutes, the adapter shuts down and internet connection is lost. I have tried installing windows adapters using ndiswrapper, with different outocomes, none sucessful. Vista driver is installed and adapter recognised, but will not work. XP driver is installed but adapter is not recognised. According to SMC support, linux is not supported by (HowTos)
