Description Pablo Castellano 2010-05-07 12:00:00 UTC

My laptop uses the rtl8187se driver and when I'm connected to a WPA protected network, the connection is very unstable. It suffers from drops in throughput continuously and at the moment my solution is using ndiswrapper.

Let me know if I can provide more details and help to fix this issue.

Does 2.6.34-rc6 work better?

How about 2.6.33?

Comment 2 Pablo Castellano 2010-06-09 19:15:18 UTC

Hi Greg, I have installed 2.6.34 today. I will test it in the next days.

Comment 3 Pablo Castellano 2010-06-18 14:32:56 UTC

After some days of testing, I can say that 2.6.34 is a bit better from what I remember being 2.6.32, but it's still very buggy.
It's difficult to test because drops of throughput and disconnections are ocasional.

Dmesg output

JFTR: the module is now called r8187se.

This attachment shows the module output that floods dmesg.

I had the same problem. My notebook is Running Ubuntu 10.4 32bits.
When I use the wireless at work, the traffic data stops, but the connection remains up. The connection is WPA/WPA 2 Personal. 

Dmesg returns the error attached.


It happens a lot when it opens and closes the door.
