Well, my iMac G5 has had internet problems, but it didn't happen as often as it does now. In the past when I first bought my iMac, the internet would only fail once every 20 or so times, but restarting the computer would fix the problem. Now, even when I restart the computer and Safari, I still get problems, only more then before. Symptoms: Slow loading times, "Failed to Open Page" or "Can't find Server" errors as well as "You are not connected to the Internet" errors. What is causing this? Airport Card? Router? Virus? All of the websites that I try to go to are really down?

This is my main computer, so if you know or find out what is wrong, please tell me ASAP.

Thanks
