So, two laptops involved here.. One has wireless access, the other does not (long story)... I've got an ethernet cable and i thought i'd share my internet connection through 'sharing' under network preferences, to allow the windows 7 computer to get online as well. Problem - the windows laptop cannot connect to the internet. I've managed to do this before with no problems when i was sharing a USB 3G dongle's connection over wifi - any ideas? MBPro's ip address is showing as a 169.xxx.xxx.xxx address, and so is the Win7 laptop..
