[ltp] Re: Linux-Thinkpad digest, Vol 1 #428 - 14 msgs

[Krishna Sethuraman]

Sorry, I'm kind of new to this 'digest' thing.  My apologies if I'm 
sending this out in a weird way.  If someone can point me to another 
place to look for just wireless issues, or knows someone with wireless 
working under Linux on a Centrino R40 in the SF bay area, I'd like to 
meet you briefly and compare setup notes and configuration information.

Thanks,

Thanks, but no luck here so far (my command is ifup wlan0 under debian, 
because /etc/network/interfaces has wlan0 listed as dhcp -- but even 
still, that iwconfig gives me an ESSID, but still 00: x 6 for the 
Access Point, and then goes back to ff x 6).  I know the hardware works 
because XP pulled up the login page at all those access points.

Now, when I tried compiling ndiswrapper, I installed the 
kernel-headers-2.6.3-1-686 from debian, but 
'include/linux/modversions.h' wasn't available there (and caused the 
build to fail), which is why I'm running under 2.4.25.  I guess you did 
something differently (and I'm wondering if this could possibly be my 
problem, although I doubt it, since iwlist wlan0 scan seems to show all 
the nearby APs just fine).

Yup.  I had to turn off DDC per 
http://ilabws13.informatik.uni-leipzig.de/~mai00dqr/a31p.html , but 
that was pretty much it.

Nope, haven't had a chance to try it, and haven't seen anything on the 
thinkpad pages I've seen mentioning it.

I wanted to keep the system as vanilla as possible (because I'll be 
turning it over to someone who doesn't have time to tweak with it), so 
rather than compiling a custom kernel (I believe ipw2100 requires a 
patch to the kernel), I preferred to compile ndiswrapper as a module 
against the debian kernel-image-2.4.25 and kernel-headers-2.4.25 
installable packages and modprobe it.

If I can run ipw2100 as a module without patching and building the 
kernel from source, it'll be fine.  But I'm still baffled why 
everything else should work (iwlist wlan0 scan, etc), but have it 
simply not associate with an AP.

This is why I tried to get to a login page near a public hotspot, to 
avoid WEP issues.  My own AP is a bit weird even with XP, but the 
public ones like Starbucks, etc, are fine under XP, just won't stay 
associated under Linux.
