Kernel not recognizing your hardware? Problems with power management or PCMCIA? What hardware is compatible with Gentoo? See here. (Only for kernels supported by Gentoo.)
Since my Intel Wireless 5100 recently died, I'm looking for a nice replacement.
Does anyone know of a half height mini-pci card that would support master mode, injection, etc. through open-source drivers? (I'm probably asking too much )
Atheros ATH9k are quite good. The driver used to suck, but since Atheros hired all the OSS devs, its now great. An half height version exist because I have one, but it was from factory, so I don't know if you can find one.
