[Bug 111502] Re: network-manager unreliable with multiple APs
I have this problem too, or a similar one. Oneiric 11.10. The Wifi here in my university has different SSIDs --- all normally with very similar strengths. I have sometime connected to all of them, but having them different privileges. For example, I have a WPA2 local SSID with full access to the network, and a WPA2 global SSID working in almost all Spanish Universities with quite reduced access (it's thought for guests, and it's the same SSID all around, so when I am in another university, I use it). There seems no way to say to NM that I want the local one, if in range, even if the global could be stronger. If a disconnect occur, or if an auto-suspend occurs, NM reconnects to one of them in almost arbitrary way. I understand the trend to keep the interfaces simple, but a way of marking personal priority should be provided. And by the way, a never ever again connect to that network automatically should be there, too: there are a lot of very insecure free hotspot around and if you make the error of connecting one time, then it's very convoluted to mark them off-limits (see also https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/891678) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/111502 Title: network-manager unreliable with multiple APs To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/111502/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 111502] Re: network-manager unreliable with multiple APs
I have the problem as well on my netbook (Asus eeePC 1000H) running Ubuntu 10.10. My wireless card reports negative values for the signal level for bad APs and positiv values for the good AP. As the noise value is not reported (noise == 0) the quality of all signals is considered as maximal. At the moment I think that the network manager, either consider quality instead of signal level to choose an AP or that it has problems with the mixing of negative and positive values. As those values comes from the driver, I think the easiest way is to fix the network manager to handle this situation correctly. Here is some example output from iwlist scan. The network manager tries to connect to the AP with MAC addr 00:03:52:29:62:43, which is actually the worst one considering the signal level.

I have been monitoring the bug while my network connection goes out but network -manager thinks I am still connected.

After that time there is no way to ping anything on the network or on the internet. In order to use the connection after that I have to force network-manager to reconnect, which repeats this cycle.

Upstream is asking for debugging logs from NetworkManager and wpasupplicant, but the instructions they provide ( http://live.gnome.org/NetworkManager/Debugging ) aren't providing the requested information. Is there a way under ubuntu to enable/extract just the wpa_supplicant and NetworkManager logs, like there used to?

[Bug 111502] Re: network-manager unreliable with multiple APs
The problem persists on 9.04. I cannot provide logs for security reasons, but I can provide detailed description of what happens and why. This is because today we've studied the problem with our network engineer. So, NetworkManager pings wpa_supplicant on regular basis with scan command. Besides blocking data throughput this way, in areas with multiple access points it results in continuous reconnect attempts because the signal from access points varies, and in the moment A the signal strength from access points looks like 208-201-197-191, but in the moment B it appears as 199-201-202-204, so wpa_supplicant breaks connection to the access point 1 and proceeds with access point 4. I've found traces of discussion in linux-wireless mailing list dated 2009-05-14 about rescans: http://osdir.com/ml/linux-wireless/2009-05/msg00596.html Unfortunately, it seems like developers didn't come to any reasonable decision with that, 'cause no stop scan option appears in NetworkManager's properties, and no reasonable solution had been given. The reasonable decision, from my point of view, would be to stop scans until signal strength falls beyond 128, e.g., because one indeed doesn't need to be very aware of other networks's presence while he's connected and is working. Probably, some scans could be initiated if the interface is idle for at least 2 minutes (i.e. no data sent or received through it). -- network-manager unreliable with multiple APs https://bugs.launchpad.net/bugs/111502 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
[Bug 111502] Re: network-manager unreliable with multiple APs
I also have trouble using network manager. I am updated to 9.04. I had apt-get remove'd network-manager a month or two ago, and instead used a terminal window to manual type the wpa-supplicant commands. This almost always works instantly. The network I'm attaching to is an open-mesh network with 3 nodes (all visible from my laptop usually). When I use wpa-supplicant from the command line, it gets connected in a second or two, then I create another terminal and run the dhclient command to get a network address. Today, I installed network-manager using 'apt-get install network- manager'.

Might not be a bad idea to try installing the package if you're having trouble. -- network-manager unreliable with multiple APs https://bugs.launchpad.net/bugs/111502 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
[Bug 111502] Re: network-manager unreliable with multiple APs
Hi. I've been having the same issues when connecting to multiple APs at my university. Wifi network with no encryption. I tried several network cards (Broadcom 4311 with the b43 driver and Atheros AR2425 with ath5k driver) and I get the same issues. I attached a commented version of my /var/log/syslog that I captured using the capture instructions on the DebuggingNetworkManager page. Network is pretty stable when I connect at my home network (Linksys WRT54G with Tomato 1.21) Thanks, Gabriel ** Attachment added: syslog http://launchpadlibrarian.net/26935792/syslog -- network-manager unreliable with multiple APs https://bugs.launchpad.net/bugs/111502 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

I get frequent disconnects too. This is on Jaunty 64-bit with NetworkManager 0.7.1~rc4.1.cf199a964-0ubuntu2 on a MacBook 5.1. See an example of the output from syslog during a disconnect and reconnection in the attached file.

[Bug 111502] Re: network-manager unreliable with multiple APs
I've been seeing this for ages with intrepid, and now jaunty. Occasionaly, telling network-manager to reconnect by just re-selecting the ESSID again, or killing wpa_supplicant helps. It frequently tries to connect to non-ideal AP's. In fact, looking at wpa_supplicant.log, it appears to never be trying any of the strongest AP's available. The ESS ID i'm trying to connect to is UWS. The strengths of the various AP's are as follows: UWS: 25/100 00:1E:7A:A7:5B:EE UWS: 43/100 00:1E:7A:A7:5B:E1 UWS: 49/100 00:1E:4A:56:97:F1 UWS: 49/100 00:1E:7A:A7:53:01 UWS: 55/100 00:1E:4A:56:8E:B1 UWS: 65/100 00:1E:7A:A7:58:6E UWS: 71/100 00:1E:7A:A7:58:61 UWS: 72/100 00:1E:7A:A7:58:41 I'm attaching syslog, wpa_supplicant.log, and the output from sudo iwlist scanning is below: wlan0 Scan completed : Cell 01 - Address: 00:1E:7A:A7:58:61 ESSID:UWS Mode:Master Channel:1 Frequency:2.412 GHz (Channel 1) Quality=71/100 Signal level:-63 dBm Noise level=-96 dBm Encryption key:on IE: Unknown: 0003555753 IE: Unknown: 01080B0C129618243048 IE: Unknown: 030101 IE: Unknown: 0706434120010B1A IE: Unknown: 2A0100 IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : 802.1x IE: Unknown: 3202606C IE: Unknown: 9606004096000B00 IE: WPA Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : TKIP Authentication Suites (1) : 802.1x IE: Unknown: DD06004096010104 IE: Unknown: DD050040960305 IE: Unknown: DD050040960B09 IE: Unknown: DD050040961401 Bit Rates:5.5 Mb/s; 6 Mb/s; 9 Mb/s; 11 Mb/s; 12 Mb/s 18 Mb/s; 24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s Extra:tsf=01342521c11b Extra: Last beacon: 3820ms ago Cell 02 - Address: 00:1E:7A:A7:53:02 ESSID:eduroam Mode:Master Channel:6 Frequency:2.437 GHz (Channel 6) Quality=49/100 Signal level:-79 dBm Noise level=-96 dBm Encryption key:on IE: Unknown: 0007656475726F616D IE: Unknown: 01080B0C129618243048 IE: Unknown: 030106 IE: Unknown: 0706434120010B1A IE: Unknown: 2A0100 IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : 802.1x IE: Unknown: 3202606C IE: Unknown: 9606004096000B00 IE: WPA Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : TKIP Authentication Suites (1) : 802.1x IE: Unknown: DD06004096010104 IE: Unknown: DD050040960305 IE: Unknown: DD050040960B09 IE: Unknown: DD050040961401 Bit Rates:5.5 Mb/s; 6 Mb/s; 9 Mb/s; 11 Mb/s; 12 Mb/s 18 Mb/s; 24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s Extra:tsf=013424cf7929 Extra: Last beacon: 3248ms ago Cell 03 - Address: 02:02:80:D1:FA:53 ESSID:OLSR Mode:Ad-Hoc Channel:11 Frequency:2.462 GHz (Channel 11) Quality=73/100 Signal level:-61 dBm Noise level=-96 dBm Encryption key:off IE: Unknown: 00044F4C5352 IE: Unknown: 010482840B16 IE: Unknown: 03010B IE: Unknown: 0602 Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s Extra:tsf=0072f989 Extra: Last beacon: 2836ms ago Cell 04 - Address: 00:1E:7A:A7:5B:ED ESSID:eduroam Mode:Master Channel:161 Frequency:5.805 GHz (Channel 161) Quality=40/100 Signal level:-82 dBm Noise level=-98 dBm Encryption key:on IE: Unknown: 0007656475726F616D IE: Unknown: 01088C129824B048606C IE: Unknown: 05040001 IE: Unknown: 0712434120240414340414640514840314950414 IE: IEEE 802.11i/WPA2 Version 1

Sure-enough, using wpa_supplicant directly connects to the strongest AP
much much much more reliably. I'm using the following in

[Bug 111502] Re: network-manager unreliable with multiple APs
Hi, Just got home and tried again and has similar issues. I've attached the syslog. I waited a couple of minutes between resuming the laptop and entering in the screen-saver password to see if that made a difference. It appears from the log that when it fails to connect to the AP it assumes that the key is wrong rather than that the AP is no longer there and prompts for a new key. In this case I cancelled the key and it then appears it tries to connect to the next AP in the list which is my work list and attempted to connect to absa_connectivity1 (or something) I then selected the correct AP from the list and successfully connected to that. One possible solution would be to rescan for APs on resume and then attempt to connect to the known networks it can now find. This might slow down reconnection to the same AP if you just suspend the machine and try and reconnect on resume. It might be an option to have a quick reconnect option that will use the current behaviour where it tries to reconnect to the same AP on resume if you hardly ever connect to other APs but if you do like I do, one at work and one at home a rescan option might be preferable.

[Bug 111502] Re: network-manager unreliable with multiple APs
Hi, I've attached my syslog. I unfortunately did not have debugging on which I have now done and will submit an updated one when this happens again. In the log there are two connection events. On Feb 11 after 8pm (there is a gap in log times before that) I unsuspended my laptop having been at work on the 315 AP. The machine asked from the gnome screensaver password and connected fine to the barbour AP. On Feb 12 after 6am (again there is a gap in log times before that) I again unsuspended my laptop having been on the barbour AP. It should have tried to connect to the 315 but attempted to connect to barbour. It then prompted me to re-enter my WPA key which I left waiting. I then grabbed the syslog. While I was check up on a separate machine on what else to capture I noticed the network connect. It connected to the 315 AP successfully. I captured the syslog again a bit later but there is a gap between the two. ** Attachment added: syslog.out.gz http://launchpadlibrarian.net/22542992/syslog.out.gz -- network-manager unreliable with multiple APs https://bugs.launchpad.net/bugs/111502 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

[Bug 111502] Re: network-manager unreliable with multiple APs
I have the following situation on Intrepid. I will be logged into the wifi network at the office and suspend my laptop to go home. When I get home and turn on the laptop I get the connecting network manager icon with one green dot and spinning like it is trying to get a DHCP IP address. If I then click on the connecting icon I get a list of wiifi networks including all the work wifi negtworks and my home wifi network, all with a signal level. The list shows that I am connected to the work wifi network still. I then need to click on my home network to connect. What do I need to run to collect relevant data to help solve this problem? Is a possible solution to restart networking on resume?

[Bug 111502] Re: network-manager unreliable with multiple APs
[Ubuntu Hardy] My home WiFi network comprises two access points. One of them broadcasts its SSID (only because it has no provision to turn that off) and the other does not. I have used Network Manager to configure a static IP address for my laptop. iwlist scan seems to be erratic as to which of the APs it sees, if any, even when iwconfig shows I'm connected to an access point, and even when I'm sitting right next to one of the APs. I expect to be able to roam between the APs, but that does not seem to work. When I move around the house, my connection seems to stay associated, or tries to stay associated, with the access point I first connected to when I resume the laptop from suspend. If I move from near one AP to the other, and the signal strength shifts, the system does not change its association. If I move out of range of the first AP but well within range of the second, the system still does not assocate with the second one. If I'm sitting next to the non-broadcasting AP and do ifdown wlan0;ifup wlan0, the system does not pick up the closer (and stronger) AP. I have to add that Fedora Core 6 handled these transitions quite nicely (albeit with a different laptop). -- network-manager unreliable with multiple APs https://bugs.launchpad.net/bugs/111502 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

[Bug 111502] Re: network-manager unreliable with multiple APs
I will add that network-manager usually works OK when at home where there is just one strong signal from my own AP, perhaps because there are no others that it could try to roam to as others in the area are WEP encrypted. If network-manager is roaming around between open networks treating them all as equal this is nonsense logic. It is not always preferable to be on the strongest open network - why can't network manager just accept that I want to connect to *this one* and just configure my card for that and leave it be until I tell it to change? ** Attachment added: more daemon.log http://librarian.launchpad.net/7497959/daemon.log.0 -- network-manager unreliable with multiple APs https://bugs.launchpad.net/bugs/111502 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
