I know I did do a search for this topic, but all the posts I found had to do with X3i's. When I followed the instructions, however, I couldn't find the "More Info" button in my Dell Lan Utilties settings for the X30. It was worth a try though...I know this sounds kind of lame but Dell was of no help.
I'd try and ping back to the wireless router, but I don't have access to it since I live on campus and need to input the MAC address for access. I don't have my own wireless router in my room to mess with.

So any help would be greatly appreciated.
