I'm thinking of purchasing either a PCI Express card or a wireless USB adapter that can be used to create an 802.11n access point under Linux using hostapd. Notoriously, products can change quickly and one has to be sure to buy a device with the right chip set. My research so far indicates that an Atheros chip would be best - they seem to be well supported and the manufacturer is (or was) helping with the Linux drivers. A USB device would be slower, of course, but more portable - just connect it to any desktop/laptop with Linux installed. Alternatively, I could install a card in my main desktop machine, which has PCI Express slots available (but no PCI slot due to another card). Can this be made to work reliably? Any product recommendations would be welcome. On the USB side, this Web page mentions some potential devices: http://forum.doozan.com/read.php?2,6300
