After installing lion last week i keep getting wifi drop outs then i cant connect again for about 5 minutes unless i turn airport on and off about 10times. And now my ethernet isnt working either, ive checked it with cables i know are good. I reinstalled snow leopard hoping it would fix it til apple puts out an update to fix wifi, but im still having the same problems. so im guessing its a fault airport and Ethernet card as i know its not a software issue as its happening in bootcamp to(win7). will apple just replace the logic board in it? i cant get a "genius" appointment til tomorrow since they don't work Sundays it seems. How long does it take them to replace the logic board? i NEED my laptop for uni and dont want to be without it for days and days. Cheers.
