[Bug 548992] Re: Wireless connection frequently drops [deauthenticating by local choice (reason=3)]

[Alvin Larson]

Hello,

Apparently this old bug still exists.  I recently installed Debian (5.0.4) Lenny on my AMD 64 bit computer.  The kernel is 2.6.26-2-AMD6. I am having a lot of trouble with the wireless network going down and sometimes the applications start up very slowly and are unresponsive.  I removed network-manager, as suggested on another post.  This greatly improved performance but the problem hasn't gone away. I discovered that I could make the network go down by trying to install Amarok with the Synaptic Package Manager.  The following is dmesg showing (1) the situation while in a normal run mode, (2) the line produced when the network went down during the Synaptic session and then (3) what it looks
like after recovery by ifdown and ifup.

INITIAL END OF DMESG FILE:

[ 4027.427162] wlan0: Initial auth_alg=0
[ 4027.427172] wlan0: authenticate with AP 00:0c:41:fc:ed:a0

[ 4027.431386] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 4038.301775] wlan0: no IPv6 routers present

THIS IS WHERE I WAS TRYING TO INSTALL AMAROK WITH SYNAPTIC PACKAGE MANAGER.  THE WIRELESS NETWORK DIED RIGHT HERE.  FOLLOWING IS DMESG 
AFTER THAT.

[ 7597.650723] wlan0: No ProbeResp from current AP 00:0c:41:fc:ed:a0 -
assume out of range

THE FOLLOWING IS AFTER I RESTART WIRELESS WITH "ifdown wlan0" an "ifup
wlan0".

FOLLOWING IS DMESG AFTER WIRELESS COMES BACK TO LIFE HERE.

[ 7863.634497] wlan0: Initial auth_alg=0
[ 7863.634506] wlan0: authenticate with AP 00:0c:41:fc:ed:a0

[ 7863.636540] wlan0: authenticated
[ 7863.636544] wlan0: associate with AP 00:0c:41:fc:ed:a0
[ 7863.638743] wlan0: RX AssocResp from 00:0c:41:fc:ed:a0 (capab=0x401 status=0 aid=2)
[ 7863.638748] wlan0: associated
[ 7863.638761] wlan0: switched to short barker preamble (BSSID=00:0c:41:fc:ed:a0)
[ 7863.639306] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 7873.792488] wlan0: no IPv6 routers present
 

I do hope this bug can be fixed. It makes Debian very difficult to use.
