We have Comcast internet hooked up to a Linksys router. When only Windows machines are using the connection, everything works fine. When I use my Macbook Pro on the connection, it works for a while, then eventually the connection dies for everyone, and usually restarting the modem makes it work again. I am now trying to use the connection on Windows XP on my Macbook Pro using Boot Camp, and it seems to be working, so it seems like the modem doesn't like something about Mac OS X. Any ideas?
