My ISP finally got my connectivity back to at least to half of what I am
paying for so I was able to do some more testing. The results were not
favorable, and the compat-wireless-2011-08-27 is still slow again. I was
able to recover back to true speeds with compat-wireless-2011-03-18
after performing a minor tweak to an unused file. I don't remember
making this change the last time, but it works now so I am passing it
on.
Here is the latest set of instructions, again based on #298:
$ mkdir -p ~/Downloads/compat-wireless/$(uname -r)
$ cd !$
$ wget
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2011-03-18.tar.bz2
$ tar -xjvf compat-wireless-2011-08-27.tar.bz2
$ cd compat-wireless-2011-08-27
$ gedit compat/compat-2.6.39.c
ADD to the bottom of the includes at the top:
#include <linux/sched.h>
SAVE
CLOSE
$ ./scripts/driver-select restore
$ make
$ sudo make wlunload ; sudo make uninstall ; sudo make install ; sudo
modprobe iwl3945
Although I am still having problems with my ISP, this seems to be
running stably with download speeds comparable to other machines on my
network.
