This bug is only marked Invalid for NetworkManager, it's still open (Triaged, with someone assigned) to be looked at in terms of kernel drivers, configuration and whatnot.
I appreciate your concerns, but I'm just marking this as "not an issue in NetworkManager", because quite honestly I couldn't see any reason it would be related to it before, and the testing with mainline kernel builds (and the fact that it works with those) further reduces the likeliness of it being a NM issue. Additionally, Fedora 16 uses the same version of NetworkManager with sufficiently similar configuration that there is no reason to believe it might behave differently. If you can't test with the mainline kernel (and I'd suggest simply http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-oneiric/, or the previous one http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.1-rc10-oneiric/), then it's perfectly fine; somebody else might be able to. In fact, DDC did test with apparently good results, if I am to believe comment #63. Testing with mainline kernels only takes a few minutes to do, and offers a great amount of help in order to successfully pinpoint a cause for the issue. So again, I appreciate everyone's concerns and willingness to see this resolved as soon as possible, but having very similar hardware I don't see any performance issues or instability, so the best I can offer is to triage this following the data we already have as far as NetworkManager is concerned. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/836250 Title: [Oneiric] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops Status in “linux” package in Ubuntu: Triaged Status in “network-manager” package in Ubuntu: Invalid Status in “linux” source package in Oneiric: Triaged Status in “network-manager” source package in Oneiric: Invalid Status in “linux” source package in Precise: Triaged Status in “network-manager” source package in Precise: Invalid 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.
