I have a 2008-era MacBook Pro and I am using a Belkin Wireless G router with Road Runner cable internet. I've been having sporadic internet outages. Things will be going great, and then all of a sudden, my connection will die for 15-30 seconds at a time. Websites won't load. In the network diagnostics utility, it tells me that my ISP connection is dead and then it will cut back on. This happens several times per hour. I originally thought it was an issue with my ISP, and then I decided to spend a day just working in Windows Vista via Boot Camp. Well, there were absolutely NO outages and pages loaded WAY faster than they do on the Mac side. I also tried plugging in the cable modem to the computer. There were no problems there either. Since I can use WiFi without incident in Windows and hooking the cable modem directly to the computer causes no problems on the Mac side, I can only conclude that there has to be some sort of settings problem that is causing this. Does anyone else have this problem? Let me know if I need to provide more details.
