Hello mrenzmann!
I'm being able to use the internet now. Things as simple as browsing a web
page were impossible when I first opened this ticket. What seens to have
caused the difference was when I removed the artifact modules from /lib.
If I simply try to unmerge madwifi-ng on Gentoo, after emerge finishes the
files are still there. Check this:
{{{

The config file emerge mentions is related to gkrellm (that's another
story). As you can see, emerge does not remove the modules from /lib
during uninstall. If now you emerge the package again, then those
artifacts left behind will be overwritten by the new version, thus
updating the system. So far so good, if all you do is install madwifi with
emerge. But what if you install without emerge? (as I've done a dozen
times, using sources both from madwifi-old and madwifi-ng). I must admit
I'm not certain about if this is the real explanation of the issue.
However, after I manually purged every .ko madwifi file in /lib, ran a
modules-update script and reinstalled it with emerge, things seemed to
have improved a lot. I'm not saying that now I have no package losses; I
still do, but I belive those are antenna related (somewhere I heard that
the DWL-G520 antenna gets bad with time - I'll check this out); now the
average transfer rates have improved dramatically. I also switched back to
the sample algorithm. I installed anoe right after cleaning /lib, and
since this apparently solved the issue, I had the impression that anoe was
doing wonders. However, after switching back to sample with the libs issue
solved, it seemed to perform better than anoe (it's correctly chosen as
the default).
In the end, seens that in some moment I scrambled the system myself. So
it's not a madwifi bug nor a Gentoo one; instead it appears to have been
caused by the curious creature in front of the keyboard.
Perhaps now this ticket can be closed. Thank you very much for your
support!
