I can use wireless with wireless-tools fine, with no configuration at all (no configuration: I don't even need to add a single line to /etc/conf.d/net in order to use it).
However wireless-tools doesn't support WPA which I sometimes use. I have installed wpa_supplicants but having read the WPA need user specify which driver to use for it. In order to know which driver to use I first need to know what hardware I have. However lspci does not list my wifi device (nor lsusb). But the devices does exist because I can surf the Internet with it. Where do I start from here?
