Hi everyone! I've grown up with Mac Products my entire life but am no expert on computers in any sense of the word. I have an old MacBook 2008 running Mac OS X Version 10.6.8, with model identifier MacBook 5.1. My problem is I am unable to connect to any WiFi services with my computer. One day it just completely stopped working. To clarify AirPort shows that it is connected, showing full bars, but when I try to go on to the internet it doesn't work. If I go into the Network Settings it states that airport was unable to identify an IP address for the computer. I know it is not the internet service its self (my iphone, ps3, and ipad all work fine). I've also tried different internet connections at different places. The thing is, when I plug in an Ethernet cable the internet works. Basically what I'm curious about is whether the actual physical proportion of AirPort is damaged (like I said, not really an expert) or if its the software its self? I bought an external hardrive and backed up my computer in case I need to reboot it. Does anyone have any advice or suggestions for me?
