I am thinking of building an embedded system to control the heating of a building, and have identified the LPC2468-16 OEM Board from
BUT, I need a Wifi Adapter board to go with it, so it can be configured from afar (via an on-board web server, which seems to be the fashionable way to do these things). Since the board already has ethernet, and since Linux can easily do TCP/IP, and host the web server, I had expected to find a simple board that would just wire into the on-board ethernet, and simply provide the Wifi connection with configurable WPA, etc. (and even the WPA might be managed by a suitable Linux driver).
But after an afternoon of Googling, I could not find a suitable product. Yes, there were lots of boards providing a huge overkill ("our magnificent board come with onboard TCP/IP stack, web server, and everything else you could possibly want") and lots of devices that wanted to be connected via USB or serial line (which presumably involves using some flavour of PPP as an intermediate); nothing that simply sends and receives IP packets over Wifi and nothing else.
So suggestions please, and preferably one that will work with an external antenna, because I will be hoping to connect to a base station at quite some distance (though I can get by with a fairly low bitrate).
