I think I have a similar problem to an earlier post with my macbook v.10.5.8. I have to be right next to my router for the internet to function. I downloaded iStumbler but as I move away from my router at just 60% signal my internet will cut out and I get the infamous internet can't be reached page.
Additionally, this is a new problem, I used to be able to move all about my apartment with no problem. I have another windows computer that works just fine. Often, even when I have the 60% signal strength it says that I am still connected to my router, but I don't get internet.
Is there something else on my computer using the signal? Is there a way to optimize it? Is my airport going bad? What can I try to do?
What's wrong with my internet? Can anyone help? Please use simple language... Thanks!!!
