That seems odd.
Everything else seems to work.
It's just that on the network and internet menu, I have the network center, but not the setup new network interface icon.
I can connect to the internet with the ethernet cable, but not yet the wireless.
After I've installed the live cd are there any updates I can install which would help to fix it?
It really should just be there. There may be a package that you could install to correct it, but the question I have is, "What else might be missing?"
Were it my machine, I'd do another d/l of the image, check it with
md5sum, (or check the present image) if it checks out, burn a
new disk at the
slowest speed possible, then
check the disk itself with
md5sum. If the burned disk has the
same md5sum as the correct image, then the disk is fit to install from. I would then reinstall the OS from that disk.
