Q: My wifi doesn't work even when I restart it.

Lately I have been having problems with the WiFi on my MacBook Pro 13'. It has not been work since last week or so and even when I restart it it can't find the network even when I am right next to the router. The Wifi sign will  be blank and the when I press the turn wifi on bottom it stays the same. One when I restarted it though the message came up saying wi-fi: no hardware installed. The wifi picture came up as a cloudy background with a see through x. If anyone knows how to fix int it would be greatly appreciated by me because I need to use my laptop everyday. Many thanks.

MacBook Pro, OS X Mavericks (10.9.5)

    Hi,

    What are you using for wi-fi, Airport Express or something else?

    Are your Network preferences something like this?

    If you go to advanced it will show your networks.

    Sadly I think you're in the same boat as me and a smaller group with a distinct WiFi issue (there is a blizzard now of forum threads about wifi issues but many and maybe most are related to drops which is a different category).  Thursday, November 21st was my last good day of surfing wirelessly and I've been staring at the icon you described almost non-stop since the problem cropped up on a public wifi spot the next afternoon.

     

    The one proposed solution that has given me brief (about six hours of) sanity relief and a return to the Web was a PRAM reset.  I'd say give that a try and if possible do not close the lid on your laptop.  Here's an easy guide to navigate back to for doing the reset:  Step by Step to fix your Mac.  Scroll down until you find step 2.  Again it worked for me but I had since moved on to Yosemite.

     

    To confirm what situation you're facing, you can run this from the terminal (Applications > Utilities > Terminal):  ifconfig

     

    You'll get some gory detail for each network connection set up for your 'Automatic' location of your Network (System Preferences > Network)

     

    What I think you'll find is that you don't have the entry for your Wireless Card registered at all as a viable network connection.  To be extra careful you might not want to post all of that output here in the forum since it could point out your wired connection and MAC address.  Instead, you really just want to scan the output and see how many 'en' entries you have.

    CORRECTION:  Very sorry but the temporary relief above was *NOT* brought about by a PRAM reset but instead simply booting into SAFE MODE.  I've repeated a number of posted recommended fixes -first on a rebuilt Mavericks OS and then after the Yosemite upgrade- so it's too easy now to mention the latest solution I've retried.  Definitely don't want to misdirect on such a complicated problem!
