I just started working with the SPICE interface and ran into this issue
with the qemu-kvm-spice package on a 12.04 Precise Pangolin box. This is
just another issue with that package in Precise.

I recently updated to a fresh install of Ubuntu 12.04 Precise Pangolin
and the problem has gone away. I don't know if there was something
lingering from a previous upgraded install or if 12.04 just fixed the
issue, but I am working now.

It has been some time since I posted here, but I finally took the time
to update to 12.04. I did a clean install and had the same slow Wi-Fi

It looks like my instructions may not work for your subsystem, 8086:1020.
Nobody that posted success and published their output from the lspci command
shows that version. Post #278 had succes with that subsystem and the kernel
from #270.
@Sarim
Glad to hear they are working for somebody.
I upgraded to 2.6.38-10 the day it came out and I didn't have any
trouble with it. Last night I did a BIOS update on my Acer Aspire 5920
and then this resurfaced. I can also confirm that by backing out to
2.6.38-8 also works for me.
Upon reading the release notes, there seems to have been several

@CarlosRuiz_globalqss This is deffinately a similar solution. If you are
still not noticing speeds that you would expect, there are several
reasons that could be causing it. I was batteling my WAN connection
during testing, so I always had to double check with a machine running a
different OS.

Oops. Fix the tar and cd commands to use the 2011-03-18 instead of

I wrote a shell script to download and build each compat-wireless
version. I have attached the script for anyone that wants to see it. For
maintenance purposes, the script removes the downloaded .bz2 files and
any decompressed version that failed to compile with my current setup. I

I have been following this for some time and with the great improvements
I have been reading I thought it was finally time to give it a try.

I appologize for the length of this post, but I am trying to be as
thorough as possible.
After the installation and before my post last night I had rebooted my
machine.
After my post, I continued searching the forums and installed the Ubuntu
"linux-backports-modules-compat-wireless-2.
Just to test it out, I removed the
"linux-backports-modules-compat-wireless-2.6.37-maverick-generic" package and
performed the rmmod/modprobe again. An immediate test resulted in:

Should #250 and #270 be considered to be mutually exclusive, compatible,
or conjunctive?

patience.

As I mentioned earlier, I have been a linux distro user for years, but
have never had to delve into the building of individual kernel modules.
So I thought I would post this lesson of what NOT to do.
I followed the README instructions and issued the commands below:
