(Get the code!)
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 problem out of the box. So I can confirm that Bug #621265 affects Ubuntu 12.04 Precise Pangolin too. I then did the same change documented previously of removing NetworkManager and installing Wicd. All is working once again. All that said, this appears to not be a GNU/Linux, driver, or Ubuntu issue rather a Network Manager package issue since the bug is so easily fixed by merely replacing that package with a comparable one.
Here are the steps I performed:
NOTE: Plug in a wired ethernet connection while completing these steps or reverse the order of the next two steps if one is not available.
$ sudo apt-get remove network-manager
$ sudo apt-get install wicd
NOTE: To get the SysTray Icon to show up, you have to follow the tip from here:

$ gsettings set com.canonical.
NOTE: Or for a more involved, probably more correct, way to get the SysTray Icon to show up, follow the steps here:

Reboot and log back in. You will have to reenter all of your saved network credientials, so it is a good idea to swap managers as soon as the need is identified.
Just for the record, here is my upgraded system specs:
