@mathieu-tl: While I appreciate the suggestion of using mainline builds, I simply do not have the resources available to continue to update and test the various builds. This is a real issue that exists with the upgrade to 11.10 that must be resolved and not marked as either invalid or that offers the only recommendation of continously monitoring and installing mainline builds. If the NetworkManager isn't the root cause of the issue, then this thread should be kept open to reference either the correct bug associated with the issue or modified to identify this bug correctly. Simply marking as invalid because of the comparisons between two different flavors of NetworkManager on different Linux builds is not offering a resolution to this real problem that is being experienced by all users who upgrade from 11.04 to 11.10. -- 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...

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 installed 3.1.0-030100-generic #201110241006 SMP Mon Oct 24 14:07:10 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux and did some further testing. With the router operating in N mode the connection is stable and performance is very good. When I switch the router to B/G/Mixed (no N), the connection is stable but the performance is bad as noted in #54/55. I tried with 2 different routers (Atheros and Broadcom based) with the same results. So my experience is as follows. Sometime after 2.6.38-11 and before 3.0.0-12, G performance took a turn for the worse and is almost unusable even with 3.1.0. Then somewhere after 3.0.0-12 and before 3.1.0-RC6, N started working. -- 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...

Experiencing the same issue with wireless after upgrade from 11.04 to 11.10 on an ASUS R1Eseries, using iwl4965. Used suggestion to try and change wireless router from using 802.11-N G to just 802.11 G.

My apologies, but suggesting to use WICD isn't helping fixing any issues. Furthermore, it's doubtful it really fixes the issues by itself, let alone without introducing other issues (such as whether applications will notice they are online in this case). Please, test with the mainline kernel as asked by Joseph Salisbury in comment #58. There's already been some amount of testing with the mainline kernel with good success (e.g. the connection is stable even when N isn't disabled). Reported bit rate by the driver is obviously not something that should be taken at face value since it changes constantly and is probably not all that accurate. Finally, since there has been testing with good results with a newer kernel, and similar good results on Fedora (which also uses NetworkManager), I think there is sufficient proof that this isn't an issue in NM; so I'll close the NM task as Invalid. @oledoe: please file a separate bug report for your issue. This bug report is specifically for Intel devices; as opposed to the Broadcom device you are using.

Obviously, I never ment to imply for WICD to be a permanent, viable solution to this issue. However, as for my concern .. this is my workstation I use at home and at home. I cannot tinker with as much as I would like to since I require its service each and every day. Thus, I was looking for a quick and dirty workaround .. which I gathered, many others were looking for as well. I would've loved to try out a couple of other angles but I just don't have the time or the resources. I realize this is in no way helping out with solving this bug for good. Also, my girlfriend and I are eternally grateful to whoever solves this mystery. Do note: Fedora might be using a different NetworkManager version, a different patchset or might have configured their release in a different manner thus rendering the comparison between Ubuntu and Fedora a tiny bit futile, in my opinion. I wouldn't be so hasty as to declare this bug invalid for Ubuntu's NetworkManager.

Moritz, are you still using 11n_disable=1 with WICD? I suspect there might be two problems here. The first problem being N not working correctly. You can find the 11n_disable=1 trick documented for numerous distros. Based on my testing with Fedora 16 beta and the mainline 3.1 kernel in 11.10, this seems to be fixed in a later version of 3.x. The second problem is bad performance with G which doesn't seem to be happening with other distros and might be related to NetworkManager. -- 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: Confirmed Status in “linux” source package in Oneiric: Triaged Status in “network-manager” source package in Oneiric: Confirmed Status in “linux” source package in Precise: Triaged Status in “network-manager” source package in Precise: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...

Dell Studio 1747 with Broadcom BCM43224/4353 here. It would see and connect to the router, but zero traffic happening. I have now disabled 802.11N directly in the router and am using G instead. This works fine, but should only be seen as a temporary workaround. While troubleshooting, I was connected by cable as well as by the zero- traffic wifi connection. I noticed then (when being logged in to the router) that my router was seeing both connections, but listed them BOTH with the SAME MAC-address, namely that of my ethernet adapter.

Good news and bad news. I'm now running this: Linux foo 3.1.0-030100rc10-generic #201110200610 SMP Thu Oct 20 10:11:32 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux The good news is that I have a stable connection with N enabled (not using 11n_disable=1) and performance is good so far. I can't seem to get above Bit Rate=65 Mb/s even when I'm very close to the AP. My iPod is consistently above 100Mb/s as reported by the AP. The little bit of bad news is that with 11n_disable=1, the connection is stable, but I still have bad performance above noted in #54/55. -- 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: Confirmed Status in “linux” source package in Oneiric: Triaged Status in “network-manager” source package in Oneiric: Confirmed Status in “linux” source package in Precise: Triaged Status in “network-manager” source package in Precise: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...

I have a Intel Corporation Centrino Wireless-N 1000 (8086:0084) in a Thinkpad x220. In 11.04, I had good performance once I added options iwlagn 11n_disable=1.

Same issue here with a Thinkpad X200s and built in Intel 5300 agn on 11.10 with 3.0.0.12-generic kernel. After disabling n-draft, networkbitrate in iwconfig changed to 54mbit (802.11g) but it is still very slow (Internet, browsing smb) The same under normal n-draft conditions. Sometimes if i boot up nearby the router i get speeds of 3-4mb/s, under 10.04 i had 5-7mb/s (like in other OS). While writing speed is 270kb/s.

I have the same problem with my HP Elitebook 8540w, Centrino Intel-N 7300. However I notice something else as well, that has to do with this matter. The notebook has a button with which you can enable/disable wireless, the light on the button will then change from blue(enabled) to orange(disabled). With 11.10 when wireless is enabled, the button flashes irregular but fast (more than once a second) and a lot of packet loss (till 30%). A similar solution as the one of manuel fernandez #30 fixed the issue with packet loss and slow internet. However... the light still flashes on and off, while it was constant blue(enabled) in 11.04. ** Attachment added: lspci.txt https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/836250/+attachment/2556545/+files/lspci.txt -- 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: Confirmed Status in “network-manager” package in Ubuntu: Confirmed Status in “linux” source package in Oneiric: Confirmed Status in “network-manager” source package in Oneiric: Confirmed Status in “linux” source package in Precise: Confirmed Status in “network-manager” source package in Precise: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...

@Joseph Salisbury I just booted in to my previous kerne againl, and wireless did in fact work.

[Desktop-packages] [Bug 836250] Re: [Oneiric] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops
Here's the problem with using previous kernels. I tried several things immediately after installing 11.10. I tried the latest upstream kernel, 3.0.6 (at the time), and I also tried the latest developmental build with 3.1-RC9, both kernels had the same issue. However, both kernels did NOT have this issue when used under 11.04. In other words, laptop using 3.0.6 with 11.04, no issue. Same laptop with 11.10 with 3.0.6, had an issue. So, that being said, after installing 11.10, I installed the latest proven-working NATTY kernel (I believe it was 2.6.38-8) and the issue was still there. 11.04 with 3.0.6 = OK 11.04 with 3.1-RC9 = OK 11.04 with 2.6.38.8 = OK However; 11.10 with 3.0.6 = BAD 11.10 with 3.1-RC9 = BAD 11.10 with 2.6.38-8 = BAD UNLESS 11n_disable=1, then all is good. I'm starting to think this is more a driver issue, than a kernel issue. I realize that 3.0.7 has been released, but I haven't tested that kernel yet. -- 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: Confirmed Status in “network-manager” package in Ubuntu: Confirmed Status in “linux” source package in Oneiric: Confirmed Status in “network-manager” source package in Oneiric: Confirmed Status in “linux” source package in Precise: Confirmed Status in “network-manager” source package in Precise: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...

I can connect, but it takes ages and I have to keep typing in the password (it's set as automatic connection).

same with me. I was not able to connect at all in N-only mode, in N/G mixed mode i can connect but unusably slow. What shocks me is that if this is an issue with iwlagn or network manager shouldn't this be effecting more people? what could have changed in the parts specific to the Centrino Ultimate N from 11.04 to 11.10? do any of you guys have any work-a-rounds that make the system usable? have you tried a fresh install? cheers, -- 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: Confirmed Status in “network-manager” package in Ubuntu: Confirmed Status in “linux” source package in Oneiric: Confirmed Status in “network-manager” source package in Oneiric: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...

It's unclear that this is caused by network-manager yet, seeing as it's device-specific (or at least system-specific, since I'm getting very decent speeds here on a Dell system).

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.
