WiFi: No Hardware Installed randomly happening

This problem was an absolute nightmare for me. Have a 4 year old white macbook which worked perfectly except this fault, rendering it pretty useless.

Phoned around 20 different places and in the end I managed to buy a dongle that works perfectly on the latest version of iOS Maverick 10.9.2 for £10.

It is a Dynamode and the model number is WL-700N-RA

saved me a lot of hair and a lot of money!

So I have had this problem (WIFI not working, "Hardware not installed", WIFI not turning on) for six months and have had to connect my macbook pro to the internet via ethernet cable which as you can image was very restrictive :/

I have had numerous laptop technicans befuddled by this WIFI problem and most concluding with how my WIFI card must be broken and that I will need to buy a new one. The last suggestion I had on the matter was to buy a USB wifi dongle.

So I ended up buying this one, http://www.asus.com/nz/Networking/USBN10_NANO/ Unfortunately my macbook pro didn't want to read the install disc and it didn't autorun so it didn't work. After reading more forums I saw that you could download the program from the net and sure enough it worked.. BUT STRANGER when I took the USB dongle out the WIFI was still working!! The program appears to have reminded my four year old macbook pro that it is indeed WIFI capable.

So to find this miraculous program its located here http://www.asus.com/nz/Networking/USBN10_NANO/HelpDesk_Download/

Same link as above just under SUPPORT>Driver&Tools

You then click on a file when its downloaded and a file called MAC will appear, then click on install. Within 5 minutes you should have your WIFI back. My macbook pro crashed again today but without having to get the shortest ethernet cable you've ever seen out again - I was able to install the program again and WIFI was up and running once more. Moral of the story - didn't need to spend any money to fix this and not even using the USB dongle.

So happy!!

Safe mode fixed the issue for me.

Just got off the phone with tech and fixed the problem quick:

Turn computer off and plug the charger in.

Press Shift, Control, Option, and the power button all at once, release, and then immediately press the power button again.

The LED on the charger went from red to green to red and the computer rebooted. Problem was solved.

I Bought a Mac book pro with Yosemeti on it this year.

I Really don't know anything about computers so I hope this helps anyone like me!

Cheers!

Worked perfectly for me

Seems to me this is a problem within Yosemite

Never had a problem before I installed that 2 weeks ago

That is the fix. A good article about it on howtogeek.com that I found tonight when mine did it:

Resetting the SMC worked like a charm for me! thanks for all the help.

I had the same problem and tried all the solutions google could find. I ended up replacing the wifi card, still had the problem, then the wifi cable and now its fine 🙂

I had this exact same problem, and I finally solved it by replacing the cable between the WiFi (Airport) card and the logic board.
