Interesting fact...I have gotten it working, but I don't know if the
patches helped. I will explain.
I had been testing by getting connected, running wpa_supplicant and
sending a file FROM the laptop to my other linux server. This ends
up slowing down from the beginning and killing the connection.
I just tested bringing a 100k file over from the server TO the laptop
(which up until now I had not thought of trying). It did so at
decent speeds and didn't fail. Everything is working in that direction fine.
I then rebooted and loaded ndiswrapper and ran the same test. No such problem.
So, ndiswrapper can send files via scp in both directions fine.
The bcm43xx module can receive files but not send them without problems.

Okay...this still isn't working...nothing I do is helping. I'm
going to repost this message in it's entirety, including the
responses I got, and let's try this again...
------------
I've been having problems getting the driver working, and was told
to post this question here, after trying on the bcm43xx forum.
I've got a Compaq Presario R3240US laptop. It's got a Broadcom 4306
built in. This combination is working with ndiswrapper.
My AP is running WPA-PSK with AES encryption, so I'm currently
running the wireless-dev kernel (which I updated today to check
before mailing this).
First thing I noticed is that if I don't modprobe aes, I get a
kernel panic upon running wpa_supplicant. But I was able to figure
that out and once I modprobe that and bcm43xx_d80211 I'm able to get
a connection after running wpa_supplicant.
Now, here's my problem:
After a short time, the connection is lost. I've been trying to
send a 30M file through scp. I notice that the data throughput
starts at a decent rate and immediately starts falling and continues
to fall until the connection is lost.
I am currently running wpa_supplicant in -D so I can see what's going on.
Once the connection is lost, it goes into a loop where it cannot get
the handshake.
Killing wpa_supplicant, removing and reinstalling the module
sometimes works again, but the same thing occurs. Sometimes when I
attempt to remove the module, I get a kernel panic.
If need be I can attach a copy of the output from wpa_supplicant.
P.S. I thought the "Enable local IRQs while executing" patch
sounded like it might be the trick, but I applied it and it did not help.
Any help would be appreciated, or if I should be directing this
question elsewhere, a pointer to where I should direct this would
also be appreciated.
Thanks.

Matt Andruff replied:
Depending on what OS your running results may vary, what is the
current data rate that you are using?
I've seen issues on Ubuntu with having to manually reduce the rate
(iwconfig eth1 rate 22M)
to have things run consistantly. Infact, I used to have to run at
11Mb/s all the time but recent developments have let me go a litttle
faster, 36Mb/s but it's not stable, and I get some dropped packets,
meaning variable speed.

I replied back:
I'm running Slackware Linux.
It seems like the rate change ability is gone at the moment...
When I look at the iwconfig wlan0 it doesn't print rate information
and when I try to change the rate, it gives me an error saying it
cannot be changed.
I had always found bcm43xx to be defaulting to 11M in earlier
versions, and figured it was again. When I start it up and start
the scp it's only giving me around 181K/s to start and goes down from there.

Matt Andruff replied:
k when your ability returns to change returns then lets change to
11M and see what happens, if you stay without aid for a while we
could try, using the ubuntu package with alien to import it properly
to you system, but hopefully the ability to change the rate returns,
what rate is listed when you run 'iwconfig [interface]
------------
This doesn't help me...here is the output from iwconfig:
wmaster0 IEEE 802.11g ESSID:""
Mode:Master Frequency:2.462 GHz
RTS thr:off Fragment thr=2346 B
Encryption key:off
wlan0 IEEE 802.11g ESSID:"XXXXXXXXXX"
Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated
RTS thr:off Fragment thr=2346 B
Encryption key:off
As you can see, there is ***NO*** rate information. There *USED TO
BE*...I can't remember what revision I was running when it was
there...but it is not there now. I have no way of changing it. As
I said in my last message...when I attempt to change it I get a
message saying it cannot be changed:
Error for wireless request "Set Bit Rate" (8B20) :
SET failed on device wlan0 ; Operation not supported.
And, seeing the other thread on the 4306 here, here's my dmesg info:

If I'm understanding where to look from Michael Buesch's message,
this seems to me to be a wireless core rev 5...so, should it be working?
And again, this is working fine w/ndiswrapper.
Can anyone lend any assistance here?
I will try Larry Finger's solution and will write back if that
works...but wanted to post this to see if there's something I am
doing wrong here.
