But I finally found the solution. It runs over the disc drive and is prone to failure. Check out http: I had the same problem, even after a clean os x install. Many thanks!

I opened the backplate of my 17" MBP just to realize that the wifi cable was loose. Popped it in and i am back in business! BTW the last time someone opened it was Apple service team for "free" warranty upgrade of motherboard, some time last year! Thanks again!!! This finally fixed it! After researching and replacing the wifi card, I still got the "No Hardware" message. I was baffled.

Then I came across this post. I've got my wifi back. Turns out my original card is fine. Thanks for pointing me in the right direction!!! If anyone is having this issue, try replacing the cable first before buying a new wifi card. I would also like to say kudos to the ifixit customer service department. I contacted them when the first replacement wifi card didn't work and a rep called me and spent a good 15 minutes trying to work through the issue.

He then immediately shipped me out a second wifi card on the chance the first one was bad. Once I discovered the cable was the issue, I contacted him and was able to return both wifi cards and get a refund. In my experience this level of customer service is extremely rare. The Guy With the Hat. Have you attempted to reset the SMC? That would be the first step. Hold the left control, option, shift key and the power button for about 5 seconds and release. Then try to reboot.

Might as well reset the PRAM as well. Hold command, option, P, R on start up until the machine restarts. If that doesnt' have any affect we'll have to dig deeper into a potential hardware failure. What year is the machine? It could be the ribbon cable, the card itself or perhaps an antennae issue.

It was all working fine up until this morning. Posted on Dec 2, 9: A good way to find out what the problem is is to start up in OS X Recovery by holding down both Command and R keys while your Mac is starting up.

Once your Mac has turned on, look at the Wi-Fi icon at the top right corner and see if you can choose any Wi-Fi network. If so, reinstall OS X. However, if you cannot choose any network there, there's likely a hardware issue, so you have to take your Mac to an Apple Retail Store or reseller to get the Wi-Fi card replaced.
