When I changed to Windows 7 and connected to the internet, every now and then, it asked whether I wanted to stay connected. I disabled this message, but now I would like to get it back. Does anybody know how to do this?
Please try this: Go to System Preferences=> Network, then choose your Network connection(the problematic one). Click on the PPPoE tab, then click on PPPoE Options button near the bottom there should be you see 2 check boxes, uncheck both.
