How can I secure my home wireless network to prevent other users on my home network from viewing my browsing history? Let's say we have a user that I allow access to my home wireless network, but I want to prevent his from having access to my browsing history on my laptop from his computer. First of all, is that possible? I realized that sometimes, he is telling me about sites I visited online. I don't know how he could do that. It looks like sometimes he even gets my bank account password.
