There may still be an issue where a scan has to be issued in order to get the device to beacon. Also the Marvell 88w8383, if you can get one, can support mac80211 and Mesh Point operation with the libertas_tf driver and firmware: http://wireless.kernel.org/en/users/Drivers/libertastf > I'd also prefer a solution with two antennas for diversity.

Also I don't know of any that support diversity antennas. > On May 26, 2009, at 4:36 AM, Mike Rapoport wrote: > >> >> >> Jean-Pierre Poulin wrote: >>> >>> Hello, >>> >>> May I obtain your recommendation on a Linux + ARM friendly WiFi module or >>> chipset? >> >> There's wi2wi SIP module with Marvell 8686.
