[Bug 550123] [NEW] realtek 8172 wireless controller nonfunctional

[Matt Price]

Public bug reported:

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.
