I upgraded Kubuntu to 13.04 today. I'm using an ethernet connection. On every boot, networking service is running and everything is configured properly, but it can't establish a connection. I have to
sudo service networking restart
on every startup. How can I fix this? I could create a script to restart networking that runs at startup, but I'd rather find a solution than a workaround.
Can you help me?
P.S.: I found out that sometimes it boots up normally, but there's no log I found that includes different information when networking is "frozen". When it is, though, my CPU reaches over 90% for hp-systray (hp-update) is trying to look for updates but can't understand that network is unreachable.
