Re: [Bug 291760] Re: network-manager roams to (none) ((none)) - background scanning
This is NOT a driver issue. This issue is a result of NetworkManager expecting wireless drivers to be able to bgscan and be connected/responsive at the same time. It is not a driver issue because there's probably nothing WRONG with the driver other than NetworkManager's false expectations of what it can do. Is there some RFC I do not know about that involves bgscans to not interrupt or interfere with current connections? How much do the first 2 letters of bgscan actually promise? The solution to this bug is and has always been to include a simple setting for enabling bgscans. We had a patch for this behavior a while ago, but some developer shot it down screaming something about NM is not broken, your drivers are. Sure, my drivers are not that great, but I do not have many options, and it's a lot easier to write an if statement and settings panel than it is to write a wireless driver. This seems like a simple fix, and it's affected 3 of my (different) laptops so far. End user options are to use WICD, roll their own patched NM without updates, do it cmdline/conf files, or run Windows / Mac. I chose WICD.

Re: [Bug 291760] Re: network-manager roams to (none) ((none)) - background scanning
I installed Lucid recently, on a work network with 3 other people. Every two minutes, the network would go down for 10 seconds due to my MacBookPro 3,1's Atheros card's background scanning. Again, I had to just install wicd. The fact that it's broken on my system is not so bad as the fact that the entire wireless network around me went down during those (now unsyslogged) bgscans. It's network manager's fault for triggering scans in a driver that has good support for bad hardware or bad support for good hardware. This could all be fixed with a network manager configuration file, interface, or anything. But it won't. It's been a problem for years. -Nthalk On Thu, Apr 29, 2010 at 4:52 PM, Peter Zieba pzi...@networkmayhem.comwrote: I can confirm this problem across several models of Dell Laptop, across several brands of wireless NIC. The same behavior is exhibited on Karmic and the Lucid RC. Hence, this is likely not a driver problem. The problem manifests itself by constant disconnects at random times with similar messages related to roaming from none. Also, our specific wireless deployment works properly for the same hardware platforms (Mostly various dell laptops), running WIndows XP and Fedora Core 12. OSX also works. Thus, RF and configuration issues of the wireless infrastructure are not likely. This particular deployment uses a Cisco 5508 Wireless LAN Controller with 1142 Access Points, configured with sane defaults for most things. Users authenticate via WPA2 / Enterprise, AES+TKIP, 802.1X Version information of Fedora Core 12 is being provided as a reference for a configuration that does work properly with Network-Manager: Network Manager: 0.7.998-2.git20100106.fc12.x86_64 Netowrk Manager Gnome: 0.7.998-2.git20100106.fc12.x86_64 wpa_supplicant:0.6.8-8.fc12.x86_64 kernel:2.6.32.11-99.fc12.x86_64 Working around this issue involves simply not using Network-Manager, and setting up wpa_supplicant manually on Debian/Ubuntu. This issue seems to have lingered for quite some time, and it seems that several other seemingly related issues may be making addressing this problem more difficult. It does, however, impact the usability of wireless in a very serious way, and seems to apply to a fairly diverse set of hardware. I am tempted to speculate that this issue may be more common for people using enterprise authentication, possibly explaining why it hasn't been caught/isolated and addressed earlier.

Regardless of whether I am connected or not, when I open the NM menu to see broadcast networks, it is going to have to scan then, right? So if that scan causes me to temporarily lose connectivity, that is a bug that needs fixing much more importantly. On my AR5418 (ath9k) I see the message every 2 minutes ONLY OCCASIONALLY now. It was happening in the early hours of this morning but it isn't happening right now, for example. As an aside, sometimes I get disconnected and it won't go past one green globe stage (yeah, thanks NM error feedback for that useful info).

Re: [Bug 291760] Re: network-manager roams to (none) ((none))
OK - I've got some good news and some bad news. The good new is that I created a usb key of Jaunty alpha 4 to test, and as far as I could tell, the problem did not occur. My wireless connection did drop out periodically, but that actually *did* seem like a driver issue (when it died, it went completely out, and it was intermittent. You could set your watch by the problem I'm having in intrepid.) The bad news is that, in the interest of science, I installed the latest jaunty packages of network-manager, network-manager-gnome, wpasupplicant, and a handful of other packages I needed to satisfy dependencies on my intrepid setup. Unfortunately, the problem seems to still occur. I even did remove --purge on the old packages before installing the new ones. In other news, I check my friend's setup, and she has the same problem, but she is using the broadcom wl driver (i'm using intel iwl3945), and her setup was a fresh intrepid install from 2 months ago. So, this is really confusing - the fact that I'm running most of the jaunty software makes it seem like a driver issue, but the problem occurs across drivers. Could it be a bug further down in the kernel wireless stack? Any other ideas on how to debug this? Here's the list of packages I updated: libgnome-keyring0_2.25.90-0ubuntu1_i386.deb libnss3-1d_3.12.2~rc1-0ubuntu2_i386.deb network-manager-gnome_0.7-0ubuntu1_i386.deb libnm-util1_0.7-0ubuntu1_i386.deb libxcb-render-util0_0.2.1+git1-1_i386.deb wpasupplicant_0.6.6-2_i386.deb libnspr4-0d_4.7.3-0ubuntu2_i386.deb network-manager_0.7-0ubuntu1_i386.deb -- network-manager roams to (none) ((none)) https://bugs.launchpad.net/bugs/291760 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, the problem is not directly reproducible, just at certain times the connection seems to break since the throughput heavily drops, pings are not delivered and so on. When I then check the log, entries as attached appear.
