Replace the AirPort card
The airport card of my MacBook Pro 17" core i7 mid 2010 is no longer detected after I've upgraded the RAM from 4 to 8 GB.
I've tried reinstalling the two 2GB chips with no better result.
The airport card (now called Wi-Fi card under Lion) does not appear in "System Information/Network/Wi-Fi" whereas it does on my wife's MBP (13" 2011").
I suppose that the card is unfortunately "dead" and should be replaced.
Has anyone any experience with this replacement and would kindly publish the relevant step-by-step guide.
Is this a good question?
