I have 2 15" (2007-2008) MacBook Pro's that have no wireless connection at all. Both says "No Airport Card Installed." Switched wireless cards and still same problem. Also tried with wireless usb adapters, after installing drivers, problem fixed for about 2 minutes and went out again. Could this be possible motherboard problems/shortage/ left I/O board or something of that sort? Also when I try usb port on left side doesn't work AT ALL. Any suggestions?
