Hi,
I was asked to post to this list wrt the problem I have with the wireless on
my new laptop
I have just bought a Thinkpad Edge 15, which has the following card
*-network
description: Wireless interface
product: RTL8191SEvB Wireless LAN Controller
vendor: Realtek Semiconductor Co., Ltd.
physical id: 0
bus info: pci@0000:09:00.0
logical name: wlan0
version: 10
serial: 5c:ac:4c:bc:27:1e
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=rtl819xSE
driverversion=0019.1207.2010 firmware=63 ip=192.168.10.51 latency=0
multicast=yes wireless=802.11bg
resources: irq:18 ioport:d000(size=256) memory:d0500000-d0503fff
I have then tried to re-compile the drivers from realtek, with no avail,
having similar problems
At the moment in Ubuntu 11.04, I am using r8192se_pci, which seems to be
very flakey to say the least, where my connections from remote servers
disconnect within 5 minutes. It was suggested to me that I use the
compat-wireless drivers, of which I did
I tried loading the rtlwifi with rtl8192ce, but that didn't work and didn't
see my card, but then I guess that would be expected as the aliases were not
there for my card. although the DID is mentioned in the pci.h, so I was
wondering would this driver work with my card, or should I be looking
elsewhere?
Any input on advice on this card would be appreciated
thanks
Arif Ali

Sorry that I did not reply earlier, but I was traveling without access to Email.
The driver rtl8192se in kernel 3.0-rc1 is the correct one as you noted. For me,
it has been very stable. There is one fix that is in the pipeline, in
wireless-testing, but not yet in the mainline tree. The symptoms are kernel
panics due to excessive fragmentation causing buffer allocation failures. This
problem affects both rtl8192ce and rtl8192se. As it took a long time for me to
have problems with the drivers, you will likely not see the problem. The fix
should be in 3.0-rc2. If you want, I can send you the patches.

Hello, Arif.
I have a RTL8191SEvA card, not a vB. But I guess that should work. The
vendor and product ID are 0x10ec (Realtek) and 0x8171. It's working very
nicely with rtl8192se driver from rtlwifi from 3.0-rc1. That support
does not exist for 2.6.39 or previous versions of Linux.

Cascardo.
