I'm testing kernel 3.11-rc6 at the moment. No disconnects for now!
It would be really great if the issue is solved, but i think it needs a
few more time to see if the disconnects (...reason 6) are really gone.

One real disconnect for now, so that the network manager has to
reconnect.
But no more waiting to the end of days while network manager shows its
connected with full signal strength but no data are coming.
Only speed is sometimes really slow, goes from 30kbit - 300knbit while
Windows 7 handles 1.

Ok, speed goes up to 1.5 mbit as well. But sometimes has the described
slowdowns that don't show up in WIndows 7.

Should i take photo of my wifi card?
I changed my router from bgn mixed mode to g only, until now no errors.
Could you guys
@ Koen: I have also connection stability problems.
As i'm writing this even in g only mode. Same behaviour as ever. If i
reconnect via networkmanager the connection is working again but it's
only a question of time when it stops working again. Sometimes hours,
sometimes only seconds.

Yes it's a TP-Link with the latest firmware.
I installed kismet just an hour ago *lol*. You can read my mind. ;-)
Well, i have a second Thinkpad with an Atheros card, since there is
Windows installed i must see if i can find something similar to kismet.
Otherwise i install Ubuntu on it.

@Larry: I've made some debug logs from rtl8192ce module.
This is a section of it when connection is there but no data comes.
I don't know what that logs say exactly but the parity error jumps into
my eye:

I finally got it managed to monitor the two stations with kismet.
I used kernel 3.8.0-29 for this because it gets more or less imediatly
disconnected.
Tp-LinkT ist my AP and LiteonTe the realtek card.
Anyone able to see whats going wrong?

I made a seperate post because the download link don't show below it. I
didn't see the atachment list on the right at the first time.
I will make another grab with 3.2 later.
My AP is forced at 11g because the wlan card i use to grab can only do
54mbit max. Interesting that it sends 11b frames. B
Correction, my AP is forced to bg mixed , so the b frames should be
normal.

Switched my TP-Link 1043nd to Openwrt. Same problem.
Maybe the logs are interesting for Larry:

Sep 5 13:54:21 OpenWrt daemon.info hostapd: wlan0: STA d0:df:9a:46:3b:
interisting, in G mode only, there are also tons of those missing ack
messages but the connection is reliable.
My Android connects without those messages: 4c:0b:3a:85:55:3a

Connection was dropped in G mode but recovers. The following message was
in the log file as this happens:

802.11: disconnected due to excessive missing ACKs
Sep 5 15:48:08 OpenWrt daemon.info hostapd: wlan0: STA d0:df
And finally with mainline kernel 3.11 (before i used 3.2-52) still a
bunch of messages (which are not there if connected in Windows) but not
so relating to missing ACK. Looks stable at the moment with mode N:

Interesting, yesterday i run into the same full connection and no data
trouble with the 3.11 mainline kernel.
I played arround a bit with some settings in the openwrt firmware. I
forced ht-mode to 40Mhz even if the second channel was used by another
AP. And all the above messages where gone. Only
Hi all,
i bought a new Wifi card, so i am no longer affected.
But i really want to see this fixed and i came to the conclusion that i
am willing to send my Realtek card to Larry if it helps. I made a
picture of it. Don't know if there are much different versions.

Ok...
Anyway, have you seen my kismet dumps and openWRT Logs? Do they help in
any way to find out what the problem is?
Yesterday i found out that 11b didn't work with 3.11, no chance to
connect to the AP.

Sounds interesting. I test it as soon as i can.
Is there a way to only compile the affected module and not the entire
kernel? The last time i had compiled a kernel was around Debian 3.0
"woody" so my knowlege about this has gone away ;-)
