I have this problem with my laptop and my desktop. At my house my parents have an older computer which they have hooked up to our router, I can connect wirelessly to this on both my laptop and desktop but for some reason it won't let me browse the internet or do anything internet related unless I hook it up to a cable. Anyone have an idea as to what might be going wrong? Both computers are running Windows 7, while my parents are running XP. Also my moms iPad can hook up wirelessly no problem.
