I've had my iBook for about 2 years now. Used to have a Netgear router that I used with my cable internet, now I have a Linksys which I've had for about a year. Recently, about the last 2 months or so, I've had problems with my airport/internet connection. About every 1 to 3 days or so when I try to surf the internet, the browser will come up saying I am not connected to the internet, then my airport icon at the top of the screen will drop to no signal. In the beginning, I rebooted my router, but it's been happening so frequently now that I'm sure it's not a router problem. Help? Thanks.
