26 Hope that you get a more useful response.... FWIW, I Had precisely these
27 symptoms on my Sony 2200 laptop - and can't tell you why - but it is rock
28 sold now. I think there were two things going on:
29
30 1. This might be a "kill" switch? Some of my problems were certainly due
31 to the kill switch. I finally noticed that the little wireless LEDs were
32 off. I had turned them off while using the windows OS - given that it is
33 susceptable to the wonderful new driver attacks - and had failed to turn
34 it on when booting up hardened Linux (which I believe is NOT susectable to
35 the driver buffer overflows).
36
37 2. I also suggest a step by step walk-through of the following page (check
38 your kernel config).

42 P.S. Contrary to their suggestion, I emerged the latest driver/firmware
43 from portage.
44
45 Newbie. (HTH; good luck.)
