I have a friend that has an unsecured wireless G connection. I know this because i built his computer, and he demanded a wireless connection so he did not have to run ethernet cables from his downstairs to his upstairs room. Say I park outside his house with my laptop. All of a sudden a dialog box pops up saying I have a new wireless connection available by linksys. I connect to this wireless connection and have free internet as I assume. So this means I have access to his network.

Well my question is, what else can I do by invading his wireless connection besides looking at his "Shared Documents Folder" since he prob isnt smart enough and doesnt care to share any important information with his parents computer. And getting free internet.

Can I look at his web logs or anything, Just curious of what I could do.
