[gentoo-laptop] Compaq laptop pcmcia wireless network setup

Hash: SHA1

I've just reinstalled Gentoo on my laptop, which seemed like a good idea
at the time.  Now I can't get the wireless card to see any access
points, though it worked before.  I could use some help from a wireless
guru, or from somebody who has a similar configuration working.

(hoary old) Compaq Armada 7800
Netgear PCMCIA wireless card, MA521 (RealTek 8190 chipset)
Gentoo Linux from 2005.1 liveCD
kernel 2.6.12-gentoo-r6
wireless-tools version 27
rtl8180 version 0.21-r1
Modules r8180, ieee80211_r8180, ieee80211_crypt_r8180 are all loaded.

When I run "/etc/init.d/net.wlan0 start" the output is:

 * Starting wlan0
 *   Configuring wireless network for wlan0
 *     no access points found
 *   Couldn't find any access points on wlan0
 *   Failed to configure wireless for wlan0

I've attempted this in several locations where I know there are access
points (e.g. outside a restaurant that advertises wireless access), so
I'm convinced the problem is on the laptop rather than on the access
points I tried to use.  I could be wrong about that I suppose.  I don't
have my own access point to experiment with.

I've saved all files from /etc before I did the reinstall, so if it
would help to know about an old version of /etc/whatever, I do have that
available.

Any clues would be appreciated.

What's the output of "iwlist scan" ?

I had the same problem with my wireless card.  Try "ifconfig wlan0 up"
before your /etc/init.d/net.wlan0 start

OK, that seems to get us a little closer.  Now the output of "iwlist
scan" is:

	wlan0     No scan results

That's a result that makes intuitive sense, at least, when there are no
access points around.  However, I get the same result when I parked the
car next to a wireless-equipped restaurant during my lunch hour, where I
would have expected to see the access point if not connect to it.

Is there more information I can provide on my configuration that will
help diagnose this?
