I just updated my OS. Its an older model of the MacBook OS x. I actually did a reinstall/fresh install because i did it wrong the first time (wasn't paying full attention). This time i installed it correctly by deleting everything first. Now i cant connect to wifi, anywhere! I think there is something wrong with Airport? Well, thats ONE thing wrong i guess. Can anyone tell me why it wont recognize wifi or if it is a software issue or a hardware? Ive ran the disk utility which said all was fine. Thanks in advance.
