Hi,
this will be a lot of text but I would like to describe my problem in as much detail as possible. The relevant information abouth my hardware is at the end.
Having installed Kubuntu 12.10 AMD64, I've been experiencing issues with the wireless connection. I've been previously running Ubuntu 12.04 without any issues.
I made a live USB and in the live session, the wireless was available and I managed to connect to my router without any problems. I chose to perform a full install.
After a first restart following installation, there was a red cross on the network manager icon and clicking on it didn't reveil any networks and it said that "Wireless unavailable".
I though that another restart may help and sursprisingly, it did. Wireless' connections were available, I connected to the router, the connection was stored and I chose to connect automatically.
Following another restart, the network manager indicated again that the "Wireless unavailable" and I couldn't see any connections. Looking at the "Network managment settings", my stored connection was there.
Next, I'm not sure whether I deleted the stored connection or just simply restarted, but this time I plugged in the wired connection and then I could connect to the Internet and also, the wireless was available and I could see other connections.
I took a chance and applied all of the available updates as I thought that perhaps it was a known issue that an update might have fixed. After updates were applied, I've restarted using only wireless connection and could see my connection and connect to it this time around.
Now I was happy because I thought updates fixed the problem. However, restarting again, same problem: "Wireless unavailable" and no connections to connect to!
In anger, I deleted my previously stored connection and shut down and went for sleep. This morning, I started the computer, and wireless was working again!
It seems as though the network manager has troubles on restart after a connection has already been established and stored among "network connections". It seems to work after a restart (offering connection to connect to) only if no previous connections are stored.
Could anybody help me debug and fix this very anoying problem? Right now I am forced to connect manually after each restart and also must remember to delete the connection before each shutdown. I will happily provide more details if needed.
Thanks in advance.
Kind regards,
Veroslav
