Hello I'm using the latest revision of compat wireless on a Debian Lenn= y=20
with a 2.6.27.7 kernel downloaded from kernel.org.

uname -ra
Linux notebook 2.6.27.7 #1 SMP Thu Nov 27 15:12:29 ARST 2008 i686 GNU/L= inux

My notebook is fabricated in Argentina by Bangh=F3. It has a rtl8187 us= b=20
wireless card.

lsusb | grep Realtek

Bus 001 Device 003: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187=20 Wireless Adapter

The thing is that when I'm downloading something using a bit torrent=20 client the connection falls. Network Manager (v0.7.0) still shows the=20 connection as active showing the intensity of the signal, but I can't=20 use the network.
I've search in the syslogs, messages and daemon.log and I can't find=20 anything unusual. At least form me.

When the connection stops I've to reload the driver with

rmmod rtl8187
modprobe rtl8187

I'm a little far from de AP but it becames stable at 11Mb/s and it only= =20
falls with the bit torrent client.
The time it takes to fall is radom, and sometimes it happens after 10=20 minutes less or more.
I've tried to limit the torrent bitrate to 100KB/s and 80 KB/s and=20 nothing. Also tried to use a 5.5Mb/s connection to the Ap, but nothing=20 improves.

Ah! my conection is using WPA Personal for authentication. My wireless=20 router is a CNet.

I've already tried with ndiswrapper and it doesn't worked.

Sorry about my english and if my description of the problem is not=20 useful. Please tell me what information you need.

Please help me! Thanks!

I have had the driver fail for my RTL8187B, but it usually takes 18-24 = hours. It
is good to know that a torrent client makes it happen more frequently. = Perhaps I
can capture the wireless packets and see where it fails.

Thanks for your report,

Larry
