Comment(by SteveB):

 Replying to [comment:1 carrano]:
 > 3) As WEP behaves very differently on different models of APs, we need
 the AP's model. We know, for instance that the steps to connect to a WEP
 enabled Apple Airport Express is different than those for connecting to a
 WEP enabled Linksys WRT54G, for example.

 I can confirm case (3) with my XO that arrived yesterday.  I now have it
 working.  The symptoms were identical for two different WEP-protected
 access points, both of which are usable from other computers.  Multiple
 tries, checking and re-checking the WEP passphrases and hex keys being
 used, as well as connection mode, gave identical results: failure.  I did
 not observe any interference with other computers during the attempts (a
 VPN connection on one of them stayed up, and it has a very short timeout),
 but since I never connected, I don't know if it would have happened then.

  %uname -a
  LINUX xo-10.E5-21.localdomain 2.6.22-20071121.7.olpc.af3dd731d18bc39 #1
 PREEMPT Wed Nov 21 00:39:06 EST 2007 i586 i586 GNU/Linux

 Both wireless access points use 128-bit WEP.  One is a Linksys WAP11
 Wireless Access Point (802.11b only).  No DHCP - it passes that through to
 the underlying router it's connected to, a Cayman 3546 (ASDL modem).
 (Turning off WEP, this worked fine and I get internet access, as expected.
 I then deleted the network.cfg file, turned WEP back on, and rebooted the
 XO.)  Second AP is a Netgear WGR614 (802.11g), which is doing DHCP.  Both
 are old -- old enough that they didn't do WPA.  When I clicked either of
 these in the Neighborhood view, it pops up the expected security dialog.
 Watching (tail -f /var/log/messages), which I started just prior to
 clicking, I tried first the WRG access point, then the Linksys access
 point, trying both passphrase and hex version of the WEP key, and tried
 both modes.  These all yielded a ">45 second DHCP timeout error".

 Checking the firmware version of the WGR614, I found it to be version 1.1,
 rev 01.  Old, old, old...  I checked the Netgear website, found the latest
 version of firmware for this hardware (version 140, dated in 2004),
 installed it, and the XO now connects!  There is something with the old
 (pre-final 802.11g standard) firmware behavior that XO doesn't like.

 I could try updating the firmware in the Linksys, which is also old
 (firmware revision v2.05, Aug. 04, 2003), to see if that fixes it as well,
 but if someone would like me to ship it to them to figure out what's going
 on, or tell me what logs to collect, I'll hold off.
