dhclient causes WPA authentication to be dropped
Last modified: 2007-11-30 17:11:31 EST
Description of problem:
Running dhclient on my Atheros network card causes the previously successful
WPA authentication to fail.
Version-Release number of selected component (if applicable):
Every time. (Tried about 5 times. As soon as I stopped using dhclient and
instead configured manually, everything worked).
Access point is a LinkSys WAP54G.
Steps to Reproduce:
1. Insert Atheros-based wireless card
2. service wpa_supplicant start (configured with key_mgmt=WPA-PSK, proto=WPA)
3. Do "/sbin/iwconfig ath0 essid MYSSID"
4. Wait for "/sbin/iwconfig ath0" to demonstrate that association has been
5. Run "dhclient ath0".
dhclient obtains an IP address, updates the interface, and then immediately
wpa_supplicant gets authentication failed and remains in that state. (This
causes dhclient to quit, too).
However, if you don't use dhclient (i.e. configure the interface manually with
"ifconfig" and "route" and edit /etc/resolv.conf manually), then the interface
continues working fine. (I am currently entering this bug via the interface in
question, having configured it manually).
I used this same setup with this same access point on Fedora Core 4 (fully
updated) about 2 months ago, and there were no problems.
Everything works happily.
My system is fully updated.
Sorry - bug is elsewhere. Closing.
