#1958: beacon miss causes client to reassociate
------------------------------------+---------------------------------------
Reporter: [EMAIL PROTECTED] | Type: defect
Status: new | Priority: major
Component: madwifi: driver | Version: trunk
Keywords: beacon miss disconnect | Patch_attached: 0
------------------------------------+---------------------------------------
I'm sorry for this duplicate but since the milestone of #848 has been
reached ''and'' the patch there can't be applied any more, I had no choice
than trying again.
This problem is reproducible -- 1 beacon miss, 1 disconnect -- and it
happens only, when the client has to transmit lots of data.. something
like `dd if=/dev/zero bs=1M | nc AccessPoint port'.
This bug makes my ath card almost unusable for large file transfers (daily
backups!), so I'll be very happy to assist.
Kernel: 2.6.24
Madwifi: trunk (changeset 3677)
Hardware: IBM T42 with a Winstron CM9
Access Point: FreeBSD 7.0
BTW: FreeBSD 6.2 on the same device does not show any similar behaviour.
