Bug Description
This may be either network-manager or kernel, depending on triage...
I have verified this on both a Lenovo X201 and a Lenovo T500 laptop.
Both work perfectly with fully updated 10.10 and 11.04 versions of Ubuntu.
However, booting into a fully updated 11.10 (as of 28/08/11) I get very poor wireless networking performance. Between 6-10% packet loss, very very slow connection and transfer rate. All in all, practically unusable.
I have reported the bug on the X201 laptop, I will add the similar logs from the T500 also if required.
As soon as I swap back to either 10.10 or 11.04 I get perfect wireless, it's only on 11.10 that I get problems, this would suggest it's not hardware or configuration on my side.
I have had this since first installing 11.10 which was a little after Alpha 2.
Wired connection is fine.
