network manager does not connect automatically to wpa-network on startup

[Uwe Schilling]

Binary package hint: network-manager

Since I changed the encryption from my router to wpa, hardy is unable to connect automatically at startup to the network. A second laptop with a fresh hardy-installation shows the same problems. Sometimes nm even completely forgets the password and presents an empty cell where the password belongs. I haven't yet found out why this is only sometimes the case. However, manually connecting to the network works fine.

Hello, and thank you for reporting this bug! Could you please verify that your system is completely up to date with current updates? Also, could you change the encryption back to WEP, and verify that network-manager will still connect automatically? Then change the encryption back to WPA and verify that it won't connect on it's own? Can you please provide us with what wireless adapters and drivers you are using? Thanks again for reporting this bug, and helping to improve Ubuntu!

Hi Steve,

I my systems are completely up-to-date and I even changed back to WEP and forth to WPA again this morning after the very last update. For one laptop, the problem still persists, for WEP I get an automatic connection on start-up, for WPA I don't. Unfortunately, I don't have access to the second laptop anymore, so I can't verify it for that one. I did some further testing with the following results: after a restart, I disable the device by removing the checkbox in front of the device and the network manager automatically reenables it. However, there is no connection established, and if I configure the device, the password cell for the wlan-network is empty. However, if I try configuring the device _before_ removing the checkbox, the password cell is filled in (I don't know if it's filled in correctly though, since I see only dots). It seems to me that nm somehow 'forgets' the WPA key.

Please find attached my `lsmod` and `lspci` output.

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the /var/log/syslog to your bug report as an attachment? Also you can submit more information for it by looking to https://wiki.ubuntu.com/DebuggingNetworkManager , Thanks in advance.

Here is my full syslog after a clean restart up to the moment where the Internet is working because it was enabled by hand...

And here is what was added to the syslog after a full testcase as describe in the link from Pedro

Another testcase I just noticed: The connection to the router is working. I start the network-admin and remove the checkbox in front of the wireless lan connection. After a few seconds it is automatically reactivated. However, the connection to the router is not established. If I click on properties, the password field is empty. If it is entered and I click "ok", then the connection is reestablished. The syslog-output created in this process is again attached.

Since this report have a long time without activity, could you check (if is possible) in latest version included in Karmic if this issue is still happening? Thanks in advance.

I don't experience the issue under karmic anymore, and I cannot
reproduce it.
