Comment 288 for bug 621265

@Radosław

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-2.6.37-maverick-generic" package and received similar results.
I left my machine powered and attached to my home network today. Before I read your request I ran a test and received:
   Download Speed: 5092 kbps (636.5 KB/sec transfer rate)
   Upload Speed: 624 kbps (78 KB/sec transfer rate)
   Fri 18 Feb 2011 09:08:25 PM CST

This is comparable to my wife's M$ machine.

After I read the post I went ahead and followed the instructions and received:
   Download Speed: 5010 kbps (626.3 KB/sec transfer rate)
   Upload Speed: 623 kbps (77.9 KB/sec transfer rate)
   Fri 18 Feb 2011 09:10:42 PM CST

This appears to have had no change as it was already at the expected rate.

Just to make sure, I rebooted the machine and received:
   Download Speed: 1132 kbps (141.5 KB/sec transfer rate)
   Upload Speed: 622 kbps (77.8 KB/sec transfer rate)

I performed your procedure (i.e. rmmod followed by the modprobe) and received an initial result from SpeedTest.net of:
   2011-02-18 9:39 PM CST 5.22 Mb/s 0.63 Mb/s 35 ms

I performed another one with BandwidthPlace.com and received:
   Download Speed: 1127 kbps (140.9 KB/sec transfer rate)
   Upload Speed: 634 kbps (79.3 KB/sec transfer rate)
   Fri 18 Feb 2011 09:42:07 PM CST

Just to make sure it wasn't a fluke, I ran SpeedTest.net again and recieved:
   2011-02-18 9:40 PM CST 1.18 Mb/s 0.63 Mb/s 36 ms

I will leave my machine up tonight and see what I get in the morning. Is there any other logs or commands that would help in troubleshooting this problem? I am also a Software Engineer, but usually work on embedded stuff and have never actually delved into the inner workings of the Linux kernel or drivers. I am willing to start, but it may be slow getting me up to speed and productive.

Do I need to remove the "linux-backports-modules-compat-wireless-2.6.37-maverick-generic" package before continuing or does it have any effect with the new kernel?
