Q: wifi no hardware installed

Does apple have an external port for hooking up an external wifi hardware? That's the only way it would work in your case.

I'm dealing with registry key change in messing with my keyboards key strokes and deleting pathways that connect to disk files

Real admin needs to watch out for these post, I've scene scenarios when they loose authority they have a back up good squad spam the system all over the place! This is sign number 1 with the diminish in his status like a time ticking bomb waiting to go off. Some southern cultures to lone rangers.

So I got the dreaded WiFi not installed message today. Recently been getting WiFi problems on my MBP13"-1278model. Started with WiFi timeouts. Messing around with terminal, upgrading to mavericks and resetting pram got me back my WiFi but only within 5metres from router. Just bought a Bluetooth, isight and WiFi aerial part. While replacing I noticed my old WiFi aerial (see ifixit guides) were damaged evidently from opening and closing for 3 years. I successfully replaced part and now the aforementioned sentance of death! I think it unlikely I replugged connections in wrong areas- as connections were different lengths and it is easy to see where which one goes. Maybe I Buggered the WiFi/ motherboard by doing this? Any ideas? I'm prob going to have buy a new one 3 years of constant and faithful use-definitely longest lappie life I have had! But definite design flaw- very obvious when you change part how vulnerable cables are to long-term wear and tear near lid hinges....
