hello friends! okay? I have a macbook air A1304 the wireless (wi-fi) has stopped working, and shows a warning saying that there is no hardware installed. already dismantled the airport passed clean contact on flex cable and the card itself, but it did not work tested the bluetooth works perfectly. what should I do? buy a new airport? I recently bought on ebay but as I live in Brazil shipping time takes about 20 to 30 days thank you! hugs

I left my macbook the day off, when I turn got a surprise. recognized the wifi but can not connect to any network. and after restarting the computer informs not have wifi hardware.

Had the same problem with my mid 2009 Macbook Pro 13 inch running Mountain Lion. Temporarily (appears to have worked, issue may return in a few days, hopefully not) fixed it by doing this:

  1. Make sure “restart programs” when logging in is NOT checked. See here: http://macnerd-presents.blogspot.com/201…
  2. Rebooted and held down “command + s” to go into single user mode and run /sbin/fsck -fy and if you see “disk modified” at the end, run again until you see “your disk is ok” For more info see here: http://support.apple.com/kb/ts1417
  3. Reboot and log in and see if the wifi is showing ok. If not, go into System Preferences and Network and add a new wifi connection using the default naming conventions. See here for more info: http://www.chriswrites.com/2012/05/how-t… Good Luck. Carlos.

As a workaround you can use a USB wireless dongle (just be certain the one you buy supports use on a Mac or you’ll have driver problems). It is also possible to purchase a USB ethernet cable dongle (if you can work at a place that has a hard cable connection) while you’re waiting for your part to arrive.

This happened to me on my 2009 MacBook Pro, I tried all the software fixes to no avail. No WiFi Hardware Installed, Very frustrating, If you have a range of screwdrivers available and wish to I decided to open up my MacBook Pro and investigate myself, if the problem was related to the Airport card, On inspection after removing the screen to get to the area where the Wi-Fi card is housed, underneath the black plastic clutch cover, I simply resitted the cable where it connects to the WiFi card, I then had to re connect the airport card cable on the motherboard and the display connector and battery , before putting it all back together, I then powered up the laptop and instantly I had WiFi again. There is a excellent video tutorial available on youtube: http://youtu.be/cZnaF3e2S-Y Good Luck.

Carlos estou exatamente com o mesmo problema em um mesmo modelo! Você conseguiu resolver o problema? Att!

I tried the first one and it worked perfectly thanks alot!!!

This solution worked for me. A bit more advance because of the SMD work but can save you $$$. https://www.youtube.com/watch?v=yOgrBYy0…

My wifi would not turn on and the “turn on wifi” in network preferences wouldn’t work. The computer says no hardware present. This is a 2013 Macbook air. I took it to the store and they ran diagnostics and said it was working fine. I drove home to the same problem. I bought the screw driver set on amazon to open the computer case. I found the two cables on the end of the wifi card have snap on connection to the board. One was loose and upon inspecting it I found the outside of the snap on connector was a little out of shape so it did not snap on as tightly as the other connector. I carefully bent it back out and snapped in back on and found it to be tighter and that was the fix after having wifi intermittently going out for the last few months. The computer had never been opened before so it must have been bent slightly during the original build of this computer and it finally loosened enough to lose connection. Buy the screw driver and open it up and take a careful look with a magnifying glass.

Hi, i have the same problem with my MBP 15" Early 2011, the airport Bluetooth is functional but not the Wi-fi. The Wifi Icon indicates hardware not installed. I have tried everything, Clean install, change hardware with airport cart and Antenna and the procedure outlined earlier in this page. Nothing works, i hesitate to change the flex cable Airport but I would like to be sure that this is before ordering the piece. please, help me.

Hello! I just wanted to add something quickly. I’ve spilled some water on my macbook air mouse pad and wifi stopped working, it said “no hardware installed”. I tried to do PRAM, nothing helped - I must’ve actually damaged the wifi card inside. I was considering getting a new macbook or getting it fixed (but then I was a bit worried it would take long and I could lose my data). In the end I found a perfect solution - I got a wifi dongle (extension) - you plug it in an usb port and it looks like a small pendrive. Now I can connect to the internet through it and I only spent £16 instead of £300 for fixing the thing. You can consider this solution!

Ive had a similar problem with my 2009 MacBook pro. I changed the wifi card and the cable, still no wifi card recognised, even in the system report in about this mac. it only shows the software. Any further ideas people? thanks Robert

Hello, I’m having the same problem, sometimes it appears that it has no hardware installed, sometimes the turn on option is locked, and sometimes it works normally. But when it “works” I’m using it and out of nowhere it locks the mac, sometimes it turns itself off and when I try to start loading, needing all the time I’m restarting it works again, but I use a certain amount of time and it hangs again if What happened to you?
