Bug Description
On a Lenovo Thinpad T410 equipped with realtek 8172 wireless controler, the wireless runs *very* poorly under the stock lucid kernel. manually deleting the rtl8192*ko drivers and installing rtl8192se drivers from source using dkms(version 2.6.0015.0127.2010) solves the problem, even though the git changelog suggests that these drivers are already present in the 2.6.32-17 kernel. Has source been modified in some way?
apologies for the duplication of lp:550120. couldnt get ubuntu-bug to add these attachments to an existing bug.
