I have installed Ubuntu 12.04.1 via netinstall to my Macbook (Core 2 Duo, late 2006, Macbook 2,1). The optical drive doesnt work properly and it refuses to start from a USB made with UNetbootin, but by using FireWire target mode, I partitioned the drive and "recovered" a USB mini.iso drive to one partition with disk utilities on my MacBook Pro and was able to install over the net to the whole HD, after installing rEFIt on the Mac OS X partion and restarting twice to get to the rEFIt boot menu. I chose to install to the whole HD and wiped the other partitions.
While installing I was prompted if Ethernet or WiFi was my primary network interface, and I choose ethernet, since I had a wired connection at the time. After installing, everything worked fine at the first boot, except that I got asked about a problem found and wether I wanted to forward information about it to Canonical. I disconnected my wired connection and connected to my WiFi and stored the password for the wifi network.
Next time I started the machine, it said "Waiting for network to start" or something like that for a long time while showing the Ubuntu boot screen. After waiting for a while it said "starting up in 60 seconds without networking" and after a minute more, it started. When logged into my user, there was no network menu, so I couldnt connect to my Wifi. Inside the networking control panel, there was absolutely no options other than setting up a VPN.
I restarted again and this time hooked up a wired connection to the ethernet port. The machine booted much faster and after logging in, it even remembered my Wifi network and connected to that as well. Now I am wondering how I get the machine to boot properly with networking without having to use a wired ethernet connection at every boot. Is there a config file I could edit?
