I have a MacBook Pro. I bought it a year ago because I am a Mac person and I needed something that would internet surf in real time for my work. I have a weird issue - the internet will be working fine, cruising along. Suddenly, it will go through a "black-out" period of about 4-5 minutes where it won't load certain pages (including Facebook and Google searches). Then after the 4 minutes are up, the websites will start working fine again. And then about 20 minutes later, I'll have another "black-out" period. And it keeps going on and on like that. I use Safari, but the problem exists in Firefox, too. From what I've seen, my husband's Toshiba tablet surfs the internet just fine during this period. I tried hard-wiring my MacBook Pro during the black-outs and it still didn't work. What the heck? It's starting to get annoying. I have the most recent version of Snow Leopard. I hope I am posting this in the right place.
