I have a late 2011 Macbook Pro 13". I had it repaired after water spillage on the laptop. Got everything working and returned to me and then when I turn it on I get 'No Wi-Fi Hardware Installed' and No bluetooth now! I just did a RAM reset, Hardware test nothing was wrong.... What could be the next steps? Replace the Bluetooth and Wi-Fi card? Any other steps I can try and follow. It's running the latest Maverick's operating system currently as well. Any help, tips and advice would be great as I am going around in circles at the moment.
