I have always taken great care with my laptop, I have never damaged it or dropped it before. As of late it has been telling me that my wireless adapter does not exist (which it does) and then proceeds to crash and freeze on me. When shutting it down after said crash/freeze i have to restart it multiple times since it freezes while starting up. Is this a software or a hardware issue? If so what needs to be fixed?
Maybe a motherboard issues, are you sure you don't have an Ethernet port? I think Apple is the only vendor to remove them. Try doing a BIOS update on the system, also check for newer drivers for the wireless and chipset.
