I just went trough a 'farrowing' time with this. Everything wireless stopped. So I tried this. I could not get the wireless back up. Rebooted a number of times. No wireless at all! Then the LED came on and things started working after I did a dmesg command, which makes no sense that that turned the radio on. Could just have been a heat glitch. But in all this I learned that iwconfig eth1 down is not a valid command :) One of the joys of a meeting like the IETF is there are lots of APs visable with lots of clients around and all sorts of nonsense to make wireless go bump in the middle of a lookup. IEEE 802.11 meetings are just as bad! Interop has been worst (all those vendors running their own wireless demo network).
