For what it's worth i2400m was so poor at loading its own firmware that
I had to remove it from my gentoo kernel config because it was adding
mysterious 40 second delays to boot...probably PEBKAC but not inspiring.
I did have it working under 2.6.39, I had a wmx0 device which returned
nothing on a scan (no WiMAX transmitters here in northern, northern
california I guess).
What is interesting about WiMAX:
The phy should be able to receive/transmit on a ton of frequencies
outside of wifi (I think down to 900mhz)
The hardware (transmitter/base stations) are supposedly going for
cheaper as LTE takes predominance...I could see uses here for an AWESOME
personal LAN :)
Since hardware is available, setting up a WISP could be fun, not sure on
licensing.
