Re: Intel wifi ipw showing up but not working

Hi Stefan!

sorry for the even longer delay - but dayjob was demanding, working
even on sunday.

However, if you can read this message, it means that I am connected
through the internal ipw card to WEP WiFi at the first attempt.
Wonderful. Great work, Stefan,

Both patches together applied, of course.

Outside on the balcony... battery works too checked with GNUstep's
battery monitor (written.. by me). Mail written with GNUMail... it got
me some tricks to get GNUstep linking, but also that was solved.
