Description Uwe Kubosch 2007-12-19 22:55:09 UTC 
Description of problem:
Cannot connect to wireless access point using dhcp.  It looks like association
goes OK, both green lights on the NetworkManager applet light up, but dhcp does
not get an address.

Version-Release number of selected component (if applicable):
NetworkManager.i386                      1:0.7.0-0.6.6.svn3138. installed

dhcpv6-client.i386                       0.10-51.fc8            installed       
libdhcp.i386                             1.27-3.fc8             installed

libdhcp6client.i386                      0.10-51.fc8            installed       


How reproducible:


Steps to Reproduce:
1. Boot
2. Select wireless network with public ssid and 128 bit wep pass-phrase
3. Network card seems to associate, both green lights on nm-applet light up
4. /var/log/messages lists that dhcp tries to get address, but fails

  
Actual results:
Connection fails

Expected results:
Successful connection

Additional info:
Tried with latest packages from updates, then latest packages from updates-testing.

Wired network with dhcp works.

This is an upgraded system originally installed with Fedora 7.

Wireless connection with same laptop, same access point, same wep key worked
under Fedora 7.

Comment 3 Miroslav Pragl 2007-12-29 20:07:25 UTC 
same problem here. I try to create new wireless network (just becasue SSID is
hidden) and NetworkManager keeps asking for key and for ever. As soon as I
unhide SSID NetworkManager connects. FC8/i386,
NetworkManager-0.7.0-0.6.6.svn3109.fc8, iwl3945 WLAN adapter.

I found out (B.F.Magic!) that for example opening /closing system-config-network
SOMETIMES helps NM connect.

Tried on 2 different APs (WPA and WEP), same behavior.

miroslav: there are known driver problems with iwl3945/iwl4965 and hidden SSID
networks.
Comment 5 Uwe Kubosch 2008-01-13 08:22:09 UTC 
Update:  I have tried connecting to other access points, but the result is the
same: network card associates fine, but dhcp gives no address.
Comment 6 Uwe Kubosch 2008-02-02 18:53:44 UTC 
It seems to work now.  I cannot say exactly which update fixed it.

Also, at least once I chose the wrong security mechanism.  NetworkManager promps
for WEP 128bit passphrase, even if the access point is configured for 128bit ASCII.

Here is my currently working setup:

Comment 8 Dan Williams 2008-02-02 19:51:58 UTC 
unfortunately there's no possibly way to figure out the WEP password/passphrase
-> key hashing option except to ask the user.  The AP doesn't advertise what it
uses, because everything really just uses binary keys underneath.  But to make
it easier for users to type things in, the manufacturers invented ASCII keys and
WEP passphrases, but didn't make it easy to distinguish between them for the
computer.
