[Bug 760292] New: Networkmanager Wlan works poorly
https://bugzilla.novell.com/show_bug.cgi?id=760292 https://bugzilla.novell.com/show_bug.cgi?id=760292#c0 Summary: Networkmanager Wlan works poorly Classification: openSUSE Product: openSUSE 12.2 Version: Milestone 3 Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: munguanaweza@netzero.net QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0 Network manager works poorly with opensuse 12.2 on wireless networks. Here is a list of the problems I encountered. 1. On reboot, networkmanagement won't retain the password for my WPA network. I have to input it every time. 2. After I make the initial connection, within about 10-15 minutes the connection will show as weakening, then will be dropped. After that it is impossible to reconnect to my network without rebooting the computer. It also won't connect to other available networks, and if it fails to connect to another network that network won't appear in the list of detected wlan networks in networkmanager anymore. 3. After my wireless connection is dropped, network manager won't "see" my wireless network anymore. I can be three feet away from the antenna, but it won't show the network. Using ifup I can scan for and find the network, then connect up to it. But not with network manager. 4. On opensuse 12.1, the network manager will drop the network and then won't see it for about 10 minutes or so. All of a sudden, it seems to time out and it can see my network again and connect to it. But with opensuse 12.2, I haven't been able to get it to see the network again after any time out period. Once its gone, its gone for good. 5. On opensuse 12.2, many times after rebooting the laptop network manager won't pick up my wlan network at all, If I scan for networks, it won't show up. Yet if I switch to ifup I can scan for networks, find mine, and connect up immediately. Reproducible: Always Steps to Reproduce: 1.Turn on the laptop, and expect to connect to a wireless network. 2. 3. Actual Results: As described under "details" above. Expected Results: I would expect to easily connect to an available wireless network. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It consistently can't see my home WPA network when I scan for it, even though it can see two networks from neighbor's houses. The two networks are one WEP network, and one network with no encryption. But it can't see my WPA network at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The wireless network is an open network and has no security. I have just used this network with Opensuse 11.4, and it is working normally. The icon showing the wireless network's power shows it is being received at full strength. When I connect to it using 12.2, the icon showing the wireless network's power shows that I am not connected to the network, because it has no power and cannot be received. Despite the fact that the wireless network icon in the kicker panel on KDE 4.8.4 (4.8.4) shows the network is not working, I am in fact able to use the network with regular reception. The reception is not weak in any way. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In my logs I see this occurring regularly: [58866.490820] wlan0: deauthenticating from 00:1e:58:fb:20:f7 by local choice (reason=3) This seems to coincide with NetworkManager dropping the connection. I can get it going again without rebooting by running 'rcnetwork restart' which seems to reinitialize so that it can see the AP again. For a while I added a rule to /etc/rsyslogd.conf to do this whenever that message is generated: if ($msg contains '(reason=3)') \ then ^/usr/local/sbin/reset-wlan0 The /usr/local/sbin/reset-wlan0 contained this: #!/bin/bash /etc/init.d/network restart However, this still resulted in some lost connections and pauses when it occurred, so I switched to ifup, which is far more stable, as long as I keep my machine from sleeping. (another issue there...) With ifup, the messages still occur, but the pauses are shorter at least. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I am not switching networks here but after a reboot or startup of my laptop (HP pavilion dv5) I am having the same problem. A lot of Wifi networks are in the networkmanagers list except my own one that should be connected automatically. After turn off and on the enable wireless switch as described above^ it connects instantly to my network anf my own network is now in the list.

I have noticed this with a Broadcom BCM43225, but it also occurs with NetworkManager disabled. The symptoms include very high ping RTT and packet loss even to local hosts. It's fine with a RTL8191SU USB adapter however.

I conclude that the problem lies in a sub-component of the wireless system: the WEP WPA security issue. Can others (a variety of systems) reset their router and test the different options: with/without WPA security, with/without WEP security, and so forward. This way it might be possible to nail down the culprit. If the buf is in the security system then the problem can be classified "extra MAJOR" since the solutions might affect system security and integrity.
