Public bug reported:

Binary package hint: linux-image-2.6.15-26-386

Wireless internet worked "out of the box" (dapper pre-installed by
vendor) but abruptly stopped working after a couple of hours, and
nothing I can do will get it going again. It appears that the ipw2200
hardware rf_kill is stuck on. The following may be of use:


Typical from /var/log/kern.log:
Sep  8 12:06:34 localhost kernel: [17181802.404000] ipw2200: Radio Frequency Kill Switch is On:
Sep  8 12:06:34 localhost kernel: [17181802.404000] Kill switch must be turned off for wireless networking to work.

What is strange is that according to http://ipw2200.sourceforge.net/README.ipw2200:
  rf_kill
	read - 
	0 = RF kill not enabled (radio on)
	1 = SW based RF kill active (radio off)
	2 = HW based RF kill active (radio off)


Many thanks for reading,

Mark
