My new computer arrived today -- Alienware 18. But nothing was installed. So I got the OS (Windows 7) but am stymied for lack of a network adapter. Didn't see one on the drivers CD. So no internet, and we all know what that means. Kinda baffled...

No network connector (RJ-45) on the back? Weird! Maybe it has a WiFi connection for the internet. :-/

[edit]According to this website: http://www.dell.com/us/p/alienware-18/pd.aspx, they all come with WiFi AND an RJ-45 Gigabit Ethernet IPv6 connector! :o[/edit]
