Red Hat Bugzilla – Bug 442046
Periodic Disconnects from WPA2 Router/WAP
Last modified: 2009-01-09 01:22:20 EST
Description of problem:
After noting #213088 regarding WPA related problems for wireless connections, I
installed the below listed components. This enabled me to connect to a LinkSys
WPA2 router/WAP. However, I am now noting periodic disconnects and fall back to
the wired connection.
Version-Release number of selected component (if applicable):
From F8 updates-testing:
Steps to Reproduce:
1. Connect to a WPA2 protected router/WAP
Connection is achieved, but after a time is lost and falls back to the wired
interface. The following is noted in dmesg:
wlan0: Initial auth_alg=0
wlan0: authenticate with AP 00:18:39:df:fc:29
wlan0: RX authentication from 00:18:39:df:fc:29 (alg=0 transaction=2 status=0)
wlan0: associate with AP 00:18:39:df:fc:29
wlan0: RX AssocResp from 00:18:39:df:fc:29 (capab=0x411 status=0 aid=2)
wlan0: switched to long barker preamble (BSSID=00:18:39:df:fc:29)
ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
wlan0: no IPv6 routers present
eth0: no IPv6 routers present
wlan0: RX deauthentication from 00:18:39:df:fc:29 (reason=16)
Stable wireless connection
My wifi card is in a Dell Inspiron 5150 laptop with a P4 CPU:
02:02.0 Network controller: Broadcom Corporation BCM4309 802.11a/b/g (rev 02)
and I use the b43legacy driver via b43-fwcutter.
My kernel is the latest for F8 stable: 22.214.171.124-64.fc8
I also see this in F9.
When the AP is put in WPA compatibility mode, the connection is stable.

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
