After installing wicd on my Dell laptop, I still couldn't see any
wireless networks. I rebooted and still nothing. I removed the driver
and tried re-installing but there seemed to be problems and no wireless.
I shutdown this morning and came to work. When I turned on the laptop,
lo and behold, I can see all the wireless networks here.

I'm not sure why this is now so difficult under 9.10. It worked
flawlessly under 9.04 (well almost, I needed wicd to get wpa2). If I
boot from the Knoppix 6.2 LiveCD, it boots up and sets up the wireless
without me having to do anything (nothing, nada).

Under 9.10, it seems it will work if you just fiddle enough (even if you
don't really understand all the details). Patience does seem to pay off
if you try long enough.

Thanks. I hope it works out for you.
