So, Can you please try installing the following package. It contains an updated compat wireless stack which may help.
linux-backports-modules-wireless-karmic-generic If the issue still remains even after this, I'd encourage you to also try installing the latest compat-wireless stack from upstream - http://wireless.kernel.org/en/users/Download . This will allow us to escalate this issue to the upstream developers. Please let us know your results.
