I have a rather strange issue I am hoping somebody can help me with. I am a tech guy so please feel free to get technical on me( I just am not an expert on Macs).
I have a MacBook Pro, purchased in early 2011 according to a serial number warranty check. Warranty has expired and I have no Applecare.
The machine was shut down last night as it normally would be(machine belongs to a family member). The next day, it was booted up and would simply not connect to any wi-fi networks, let alone even find them. The wi-fi adapter itself seemed to be stuck "off". Clicking Turn On did nothing.
I went ahead and did a PRAM reset. No luck
I then "inactivated" the wi-fi connection, removed it, re-added it, restarted. Half Luck.
Now my wi-fi turns on and will actually see networks, but here is the kicker:
It only connects to Non-secure networks (there is a non secure Linksys network in my area and I am able to connect and go online with it).
I have my home wireless (linksys router) on WPA2, and when I try to connect, it says "mac wifi could not join [wifi name]. a connection timeout occurred". Yes I am putting in the right key, I even changed the key to test, no luck.
I tried the same thing at my office, no luck, still says same issue, Cisco E1000 WPA2.
I have removed all the networks from the Preferred list, still no luck.
There is no filtering on any of the wireless routers, other laptops/phones/tablets connect fine.
Any advice? How come my Mac will only connect to non-secure networks?
