So I have a unibody MBP I got back in October and for the past few days, the ethernet connection has been wonky. I'll be surfing the web then I'll stop getting an internet connection until I reboot the computer. When I'm on my Windows machine listening to my MBP's iTunes via sharing, it has to stop and rebuffer the stream every minute or two. This all occurs only on an ethernet connection. Is this an issue with my Mac or some other annoyance in the network?
