Bug 390253 – sys-kernel/gentoo-sources-3.0.6 - rtl8192se works not well than r8192se_pci

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Wei-Chun Chung 2011-11-12 12:34:59 UTC]

After upgrading to kernel 3.0.6 from 2.6.3x version, my wireless card works not well with rtl8192se module.

Reproducible: Always

Actual Results:  
The wifi connections may broken dynamically but the connection still appear, and cannot ping the default gateway. Another issue is about the ad-hoc shared by windows, the newer module cannot established connection.


I'm using Lenovo X201, the wifi card is RTL8191SEvB rev 10. Is this should be a bug to the upstream of wireless part of kernel?

Can you attach the output of 'lspci`?

[Comment 2 Wei-Chun Chung 2011-11-13 05:57:33 UTC]

The output is from ubuntu. I'll attach the output from gentoo later if there's any different.

With some try in ubuntu, the ad-hoc link in ubuntu work first, but the connection may still lost after some idle. I've to remove and insert rtl8192se module to make it work again (some reset?)

I'll try in gentoo with iw and/or wpa_suppliant reply from the forum, thanks.

That's weird...

I remember I've setup a parameter (hwwep=0) for r8192se_pci which makes the module work fine but not a parameter for rtl8192se.

But I've found there's a parameter named swenc in rtl8192. After the procedures:

# modprobe -r rtl8192se
# modprobe rtl8192se swenc=1

My ad-hoc networks works fine!!!? I can ping the default gateway although the Speed in NetworkManager still Unknown. With setup in /etc/modprobe.d as a configuration, the network works with some delay (There is seconds of delay after login into my gnome desktop).

A partial solution? Strange...

Is that net-wireless/rtl8192se* you are using as a kernel module?

[Comment 5 Wei-Chun Chung 2011-11-14 13:45:47 UTC]

The net-wireless/rtl8192se* cannot be compiled and used in kernel-3.0. In kernel-3, the rtl8192se is loaded by default.

substantial work has gone into the rtlwifi drivers since 3.0.6. We're up to 3.0.37 now on that branch. Are you still having issues with 3.0.x or have you moved on?
