So recently I moved my mac into my dads house, at my mum's house, the internet works fine, both on my mac and my vista partition.. However, soon as I set it up mac worked perfectly, but I tried vista and it was saying it was too far from the access point? The whole network then went weird and neither my mac or vista partition could connect and it kept restarting and that sort of thing.. It worked fine and my mums house and now I've come back on mac today (at my dads)..I have full signal? Any help?
