Hey, about 3 weeks ago i installed snow leopard on my inspiron 1525 using this method: Boot-132 disk for Snow Leopard for Dell Inspiron 1525. | Mac Your PC

Everything worked great, and i was staying on 10.6. Just a couple days ago I decided to upgrade to 10.6.4 to install the facetime beta from Apple. I used this method: Updating to Snow Leopard 10.6.4 | DailyBlogged

That worked great for about a day. I rebooted multiple times and everything worked. the next day I took it to school, and the wifi wouldn't work. I tried turning on airport multiple times, but it just won't turn on, even with multiple reboots. It's not just the network, because the wifi doesn't work at home (I am currently using ethernet)

Any Ideas on how I can fix this? Thanks!
