Not that I am planning to construct anything, but I was looking at what's available for implementing a Wifi router.
I was expecting to find chips that implement the basic Wifi interface, but deliver raw IP or even Ethernet packets (whether or not over a real Ethernet interface). The one's that I've found that do that only handle modest data rates.
Those that provide high data rates seem to have a complete TCP/IP stack on board, and require specialised drivers.
Seems odd.
