Almost a week ago I ordered my first laptop, which I’m mainly going to use in the school. It’s a 13,3″ Toshiba R830 and it arrived last Friday. I have already installed Arch Linux and Gnome 3 on it and I’m currently tweaking power saving settings.
Anyway, when I first tried to install the operating system I did it with the netinstall image, version 2010.05, from their website. However, it didn’t work since eth0 wasn’t found during the installation. (ifconfig found wlan0, but I don’t have wireless Internet at home.) Instead I downloaded the core image, chose during the installation to install from the CD (USB memory in my case) and ended up with a working OS – but still no Internet.
I did some searching on the Internet (on my phone) and found the suggestion to download a more recent image of Arch Linux, from this site:
I downloaded the netinstall image with version number 2011.06.10 and that worked out great. 
Since my laptop is fairly new I suppose the hardware wasn’t fully supported in the earlier image. Maybe the kernel has been updated since then or something.
So if Arch Linux doesn’t find Internet, try to reinstall it with a more recent image from the link above.
