[SOLVED] Wireless - RTL 8187b + wicd + wpa_supplicant - naughty behaviour

Mark_ger · 11-04-2010, 06:07 PM

Hey, thank you!
But when I patch the driver, I get some strange output

Code:

$ patch -p0 rtl8187_dev.c rtl8187b.patch
patching file rtl8187_dev.c
Hunk #1 succeeded at 775 (offset -1 lines).
patch unexpectedly ends in middle of line
Hunk #2 succeeded at 925 with fuzz 1 (offset -1 lines).

Is that normal?

No ... that is error

But doesn't happen here, try this again:

Rogerio: thanks for the help, but for some reason I could not apply that patch properly.

However, Mandriva 2010.1 meanwhile got an update to kernel 2.6.36

Quote:

ChangeLog:
* Di Nov 30 2010 Thomas Backlund <tmb@mandriva.org> 2.6.36.1-2mnb
o Herton Ronaldo Krzesinski <herton@mandriva.com.br>
...
- rtl8187: miscellaneous cleanups and bug fixes.

I think, the new kernel module has Herton's 9 patches applied.
I installed 2.6.36, but unfortunately I can recognize only very small performance improvement :-(

Do you know if Cascardo's patch will be included in upcoming kernel versions?

From early DECEMBER/2010 the compat-wireless bundle from linux-wireless has the fix, so just follow the instructions on compat´s web page to get the wireless working (even on Debian Testing
