NM and WEP

[Patton Echols <p echols comcast net>]

Running Network Manager 0.6.4 on thinkpad, w/ Ubuntu 6.10 recenty 
upgraded to 7.4

I first started using NM when I could not easily switch from my office 
to home networks.  Both WPA secured wireless.  Both had keys in 
wpa_supplicant.conf.  NM figured them both out immediately.  Open 
networks are also no problem.  But one of the places I go has a WEP 
secured access point.  When attempting to login, I am asked for a WEP 
passphrase, when given, the Network Monitor applet shows connection, but 
the laptop never acquires a network address and after a while I'm asked 
for the pass phrase again.  This is the only network I connect to that 
uses WEP, so I don't know if there is some peculiarity of the router or 
not, but when I boot to Windows, it works just fine.

I asked this question once before, and no one had any great ideas.  So 
after trying to think about it a bit, here are my two questions:

1.  I understand that for NM to use WPA, wpa_supplicant must be 
installed.  Does the process of coding the keys into wpa_supplicant.conf 
need to be done too?  It was in my case, and it works.  But here is my 
thinking.  If NM generates and stores the key the first time (and does 
not need to get that info from the .conf file)  then could the presence 
of the .conf file be messing things up?

2. Do I need to hard code the wep access information into 
wpa_supplicant.conf?

3. (ok, I only said two . . .) Any other ideas?

Thanks
