#2068: PCI TRENDnet TEW-443PI in AP mode doesn't associate
-----------------------------+----------------------------------------------
Reporter: [EMAIL PROTECTED],org | Type: defect
Status: new | Priority: major
Component: madwifi: driver | Version: trunk
Keywords: | Patch_attached: 0
-----------------------------+----------------------------------------------
I'm trying to get '''PCI TRENDnet TEW-443PI''' card in '''AP''' mode to
work on Debian Lenny (kernel 2.6.25-2-686).
On a client side I have a laptop with '''bcm4311''' chip: `03:00.0 Network
controller [0280]: Broadcom Corporation BCM94311MCG wlan mini-PCI
[14e4:4311] (rev 01)`. It works with native b43 kernel module, or through
ndiswrapper, and it does work with other APs, so I'm almost sure the
problem is on madwifi side.
The problem is that, after a recent upgrade of madwifi-* packages, my
wireless network is almost dead: sometimes I can connect to the AP, but
performance is very poor: speed is around 1Mbit, it may start to grow, but
then drops to very low values (feels like packet loss); sometimes I can
associate with the AP, but then got a disconnect; and this morning the AP
even rarely appears in `iwlist wlan0 scan` results :(
The card worked fine the first time it was installed, unfortunately, I
can't tell the exact driver version, perhaps it was the previous one.

Oops, missed beacon. I'm aware of "The Infamous Stuck Beacon Problem", but
I usually get only one or two such messages in dmesg and sometimes not at
all, but never more than ~10.

Very bad. I've noticed, that setting AP to use another channel helps and
the client get higher signal quality and the AP appears more frequently in
scan results.

dmesg is silent, and since we are not associated, there is no reason to
try to obtain an IP / ping the AP.

That's it. I've also played with several iwpriv options like dtim_period
or bintval, with no significant success (maybe not enough).
