Public bug reported:
Within the last month, I upgraded the Intel Wireless 3945 WLAN card on
my laptop (a Dell Vostro 1500 running Kubuntu Jaunty 64) to an Intel
4965 card. The old 3945 card connected and associated quickly, and
maintained the connection without a problem. However, with the new
card, I have several problems making a connection (with the computer in
the same physical location as before). Sometimes on startup it will
take many retries to properly associate with the network (a WRT54G
running DD-WRT with WPA enabled). This process produces a number of
iteration of this:
[ 128.765890] wlan0: authenticate with AP ffff88011c04baa0
[ 128.767898] wlan0: authenticated
[ 128.767905] wlan0: associate with AP ffff88011c04baa0
[ 128.770600] wlan0: RX ReassocResp from ffff8800de45c04e (capab=0x431
status=0 aid=3)
[ 128.770607] wlan0: associated
[ 139.765641] wlan0: disassociating by local choice (reason=3)
in my dmesg. Most of the time, the wireless will connect immediately on
startup, but will then after about 50 seconds disassociate and begin the
above-mentioned cycle of retries until it connects again. Once the card
is associated with the network, though, it never drops the signal or
exhibits any other signs of trouble. I have tried using the linux-
backports-modules version of iwlagn, but this does not affect the
problem.
