Hello! Instead of typing out a book, I'll keep it brief--my Macbook Pro has many a WiFi connection problem. I've troubleshooted and attempted to fix it in every way I've read possible. It was to no avail. If I take my Macbook to the Apple Store to possibly get a repair, I'm going to have to pay for it, since I'm out of warranty, with no AppleCare. If the network chip is the problem, does anyone see that being replaceable, or will the whole logic board need to be replaced? I heard of someone's nVidia chip going bad and the whole board needed to be replaced. Yikes! Getting the board replaced isn't too short of the cost of the computer. Anyone know? Thank you!
