Bug Description
Binary package hint: network-manager
I have 2 pcs under linux (k)ubuntu that were running fine under intrepid.
After upgrade to jaunty both wifi stopped working.
My first workstation uses the ath5k with a manual configuration (networkmanager should not be used at all).
However, till I killed networkmanager (sudo /etc/init.
No strange things in /var/log/messages, some warnings in the console when restarting the connection as usual (sudo /etc/init.
After having killed NetworkManager, I get a lease immediatly.
Second pc is a sony vaio laptop using driver iwl3945.
Browsing the ubuntu forums, I had both to
- add a new file /etc/modprobe.
options iwl3945 disable_hw_scan=1
- kill networkmanager (and create a manual configuration)
to make the connection works.
doing rmmod iwl3945 would kernel panic.
If I only add the module option, without killing networkmanager, iwl3945 seems to write a lot of debug messages in /var/log/messages (iwl3945: Tuning to channel XXX, iwl3945: check TGG and auto detect 1 | 1, iwl3945: check anteena 2 1, ...) but both iwconfig and ifconfig shows that the connection is not up, and the configuration ignored !
killing networkmanager fixes the issue (well, I have the network up, but networkmanager is not working for me)
Release : Ubuntu 9.04
Package : network-manager 0.7.1~rc4.
Read elsewhere it could be a kwallet issue and/or a kde plasma applet issue.
I do not have the plasma applet running. I have knetworkmanager running.
I tried the applet. It seems to be handling better the kwallet (e.g. : asking for permission to access it), and it even seems like scanning and connecting to my network. However the connection is not stable : it constantly loses it and have to re-acquire it. It's not usable at all.
With regular knetworkmanager, it may be a kwallet issue, because kwallet never gets fired.
Trying to activate a connection seems to have no effect, and I regularly see my active iwconfig ssid to be the one of a random existing network, but never the one I asked for !
Manually configuring the network (and killing networkmanager) is ok for me and the connection is rock stable.
=> does not seem to be a module/kernel problem
Well, at least for my iwl3945 module.
My ath5k module on my other box is so slow I cannot do anything with it. I found other bug reports for the ath5k, so I guess this whole entry is a big duplicate.
Sorry for the noise.
