Wi-fi: no hardware installed

Since the upgrade to 10.7.2 on my macbook pro the wifi icon is greyed out (and can't get any access to wi-fi).
The iMac (on 10.7,2) is fine. Any suggestions to get it fixed ? Thx

I too am having the same problem. I stumbled upon the following solution from a blog. It worked for me:
Just UNCHECK that "Re-open windows when logging back in" button when you log out or shut down and then restart.

Wi-Fi: No Hardware Installed on MacBook Pro 8,2 (15 inch, Late 2011)

Hi Everyone,
For the second time now, I have to bring my Macbook Pro 8,2 (macbookpro8,2, 15 inch, late 2011) running Mountain Lion back to the Genius Bar due to a unrecognized Wi-Fi Airport adapter. The computer was purchased in March of 2012.
The problem started as I was watching 'The Daily Show" online, when suddenly, I lost connection. I clicked on the wi-fi adapter icon on the top menu bar, and saw that no access points were available when there normally were over 20, including mine in the house. I went into the network settings under system preferences and saw that the wi-fi card was off (although it was just on and still showed the full-signal indicator in the menu bar), and attempted to click the button to turn it back on with no response. All other options were either greyed-out or displayed no information. The Hardware tab didn't even display and the mac address suddenly became all zeros.
I rebooted the computer, only to discover the wi-fi indicator on the menu bar displaying no signal. Upon clicking on the icon, the dreaded "Wi-Fi: No Hardware Installed" was displayed. I tried resetting the SMC and PRAM/NVRAM with no success. I also rand the Hardware Troubleshooter ( Option - D upon bootup ) which neither saw the communications device nor reported finding any problem.
I brought it to the Genius Bar, and they ended up replacing BOTH the Logic Board, Wi-Fi adapter, and connection cable between the wi-fi adapter and logic board on July 23, 2012.
Now, it's October 10, 2012, and last night, as I was working through a VPN tunnel on the terminal on one of our remote servers, the SAME THING happened AGAIN! The connection was dropped, same scenario as above, and upon bootup I was greeted with the "Wi-Fi: No Hardware Installed" message again.
The hardware magically disappeard with no mention of this in the Console, as far as I can tell. The Console mentions the loss of connection and inability to contact DNS, but nothing relating to hardware.
For the record, the bluetooth continued to function both times I've had this issue. The first time this happened, I was running Lion and now I'm running Mountain Lion.
So apparently there is something really wrong with either the physical enclosure causing a short somehow, the quality of the Broadcom chip on this wi-fi device, or there's some type of software/power causing the chip to short out.
My compouter is as protected as can be - it's in a Speck plastic housing with a keyboard cover, which was purchased after the first incident, I use it on a hard flat plastic laptop tablet at home, and carry it around in a Timbuk2 Laptop bag. It also has never been dropped.
What's the problem here? Has anyone else had this problem?
Thanks and all the best of luck and success solving your own computer problems

Sorry for the late reply. I had a bad experience with the Apple Store and the 'Genius' Bar where I live. However, in the end, I received my MacBook Pro back from repair and everything is working.
Like I said in my previous post, the first time the Wi-Fi broke, I was using Lion. The mother (Logic) board was replaced as well as the Wi-Fi card.
The second time it broke, I was using Mountain Lion. Booting up the Recovery partition and Snow Leopard (new install) did not solve the issue. The Apple Store confirmed that the Wi-Fi card was broken through various testing, which I observed.
Since the attenna wires for the Wi-Fi run through the display, we decided the next logical step was to replace the Wi-Fi card and the display. The reasoning is that there could have been a short or cross connection in the attenna wiring that was causing the Wi-Fi cards to short-out/burn-out. The Bluetooth continued to work in both cases the Wi-Fi failed, meaning that it was unlikely a cable problem.
Since the display and wi-fi have been replaced (20121025), I've had no problems. The wi-fi card is working.
I'm glad the kext file solution has worked for you. I've seen posts on this solution; however, after determining that this was indeed a hardware failure (by using Recovery console, booting from Snow Leopard, and using Hardware Troubleshooter (it didn't even see the Wi-Fi) ), I didn't bother with fiddling with the kext (driver) files. Besides, this hardware is supposed to be designed to work with the OS without any problems whatsoever. Shame on Apple if they don't ship proper drivers for their hardware!

HDD errors - Wi-Fi: no hardware installed - Flashing ?-Folder

Hi there,
for the last one year I'm having periodical issues with my macbook pro 13'' mid 2011.
Some time ago I started a discussion https://discussions.apple.com/message/22086569#22086569 concerning allocation errors on the file system etc.
I though I got it fixed with a new hdd sata connection cable. As it turns out I seam to only scratch the surface of a much bigger problem. As you can read in the title after getting allocation errors after a reboot my wi-fi hardware is not found (this also got repaired some time ago) and now i cannot boot into my system as I'm getting the flashing folder with the question mark in it.
With me changing cables and so I only get like 1 or 2 month of peace then the whole problem starts again. Could this be like a faulty logic board or some loose connection on it? I already paid like around 300€ for repairments on this **** thing and all they said or did was changing cables. I don't believe that cables are the source of the problem.
Do you have any other advices?
Thanks in advance

Hello Guys,
I am having the same problem. In the "No hardware installed" (Macbook pro - mid 2009 model os x 10.6) Help ...please....!!!

OSX Yosemite Wi-Fi: no hardware installed

Hi ASC:
I installed Yosemite about 2 weeks ago, and at first my wi-fi (at home & work) was working fine, but then about a week ago the Wi-Fi icon at the top of the toolbar got an "X" in the middle of it and when I click on the Wi-Fi icon it says, "No hardware installed". I tried resetting the SMC on portables with a battery you should not remove on your own (from another thread) but no luck. I've googled this, YouTube-ed it, but still no Wi-Fi back. Someone PLEASE help
I'm using:
OSX Yosemite
10.10.1
MacBook Pro (15-inch, early 2011)
Thank you.

In some cases, this issue is caused by a hardware fault. A loose connection, a short circuit, or a microscopic break in a solder joint may open and close depending on temperature, making the failure intermittent.
Test after taking each of the following steps that you haven't already taken. Back up all data before making any changes.
1. If you can connect to the Internet via Ethernet, Bluetooth, or a USB network device, make sure all available OS X updates are installed. If Wi-Fi is your only means of network access, skip this step.
2.. There are a few reports that the problem was solved by unchecking the box marked
Wake for Wi-Fi network access
in the Power Adapter tab of the Energy Saver preference pane. I can't confirm.
3. Reset the NVRAM.
4. Reset the System Management Controller.
5. Start up in Recovery mode. In the menu bar of the OS X Utilities screen, there's a Wi-Fi menu. Try to connect. If it works, select Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Message 'Wi-Fi: No hardware installed

MacBook late 2008 2 GHz Intel Core 2 Duo   OSX 10.9.2
Hi,
Some advice please re. the above situation.
I was working on my MacBook when the screen froze. I can’t remember the last time this happened. Pressing and releasing the power button to shut down did not work, so I pressed it continuously until MB did shut down.
After starting it again, I was surprised to see the Wi-Fi symbol at the top of the screen was not showing its bars as usual; in their place was a white cross. When pressed, the message ‘Wi-Fi: No hardware installed’ was revealed.
When I go to About this Mac : System Report : Wi-Fi, I see this:-
Software Versions:
CoreWLAN:     4.3.2 (432.47)
CoreWLANKit:     3.3.2 (332.36)
Menu Extra:     9.3.2 (932.35)
System Information:     9.0 (900.8)
IO80211 Family:     6.3 (630.35)
Diagnostics:     3.0 (300.40)
AirPort Utility:     6.3.2 (632.3)
When I go to System Preferences : Network, it says ‘Wi-Fi Off”.
Strangely, I did successfully get online via Safari on the MB but only once. Now, there is no internet access from the MB.
I can access internet with iPhone and iPad whose settings properly show the correct home Wi-Fi name, and I can use iTunes to pass docs from and to them when they are USB connected and just by Bluetooth.
Earlier that day, I had received a warning from a friend that his email account had been hacked. Later, whilst checking Spam folder (Yahoo), I inadvertently clicked an email from him, saw that it was indeed Spam, and quickly closed it again.
Could this have contained something that caused the above situation?
Any advice as to why this has happened and its implications, please? And how to get back to normal?
Many thanks,
Graham

I had the issue after upgrading from 10.7.3 to 10.7.4. It has persisted into Mountain Lion. Recently, my late 2011 15" MBP had its wifi card and cable replaced, along with the main logic board. The logic board was damaged by the repair staff in the process of disconnecting the wifi cable. A couple of days ago, my wifi started shutting off randomly but would return after a restart. Now I've got the "no wifi hardware installed" message again. I haven't checked System Profiler to see if the wifi card is listed. Previously when I had this message, it was not. So, yes, the hardware repair fixed the problem for about a month. And now it's back.

HT4199 In the middle of using wi-fi on my Mac Book Pro, I lost contact. When I click onto the empty wi-fi icon, top right of screen I get the message Wi-Fi: No hardware installed. Any clues anyone?

In the middle of using wi-fi on my MacBook Pro, I lost contact. No other apple devices (iMac, iPhone or iPad) are affected. When I click on the empty wi-fi icon (top right of the screen) it gives the message: Wi-Fi: No hardware installed. has anyone any clues?

Wi-Fi: No hardware installed. has anyone any clues?
Unfortunately, this message is almost always an indication that the internal AirPort card on the Mac has failed and will need to be replaced. This is a job for repair shop.
If you have a recent Mac, a Hardware Test may reveal this as well:

MBA13(mid 2011) Wi-fi: No Hardware installed

Hi Community and Apple Support!
I bought MBA 13'' mid 2011 about 3 weeks ago in Houston,TX. Today in the morning, after reboot i cannot connect to any Wi-Fi network, because i see wi-fi icon disabled and it is shows: "Wi-Fi: No hardware installed". My MBA running on 10.7.3 MacOs.
I've already tried:
1). Remove all setting for network;
2). Reset SMC
3). Reset PRAM;
4). Boot in Windows via Bootcamp (wifi adapter cannot be found as well);
5). Rebooted about 10-15 times;
6). Run Wi-Fi diagnistics and it is hanged up.
I live in Ukraine, so there is no Apple Store in my country.
Please help me to fix this problem.
Thank you!
Alex

Restart the Mac but uncheck "Reopen windows when logging back in" in the dialog box.

2009 MacBook Air 2.13GHz says "Wi-Fi: No hardware installed"

So recently my 2009 13' MacBook Air has begun to give the No hardware installed on the WiFi. I am currently on Mavericks and have a couple extra airport cards lying around. So out of curiosity i tried to replace it with an airport card that came out of a functional unit and the no hardware installed still comes up. Is it because of a lack of drivers? Or is it the flex cable that is under the battery that connects to the board that causes this?

Did you try resetting SMC before adding other cards.

Wi-fi no hardware installed 10.9

Hi,
I have a macbook pro 15" (late 2008) 2,4ghz core 2 duo, 2gb ram.
I update for the new OSX Mavericks 10.9 and i loose the wi-fi. When i click in the airport icon appears "wi-fi: No hardware installed"
I already clean the PRAM, SMC and run the repair permissions and still not working.
What can i do?

Its not an OS problem.
Don't believe them when they tell you this - it only means that they don't know what the problem is, how it arises or how to solve it.
I'm on 10.6.8. When my late 2010 iMac was just over a year old, the intermittent WiFi disappearances became permanent. (I normally connect to the internet via Ethernet so it was not generally an issue before then). Naturally I had already tried all the usual: PRAM reset, PMU reset, new User account etc.
Despite being out of Apple's 1 year warranty, I invoked my consumer rights and Apple agreed to repair my iMac for free. A local approved repair company replaced the cable attaching the WiFi card to the motherboard and the WiFi came back to life.
That was back in late 2011. I'm still on the same OS. Yesterday (21st Jan 2014) I needed WiFi again and - Quel surprise! - "No WiFi Card Installed". Just over 2 years after the repair and with hardly any use, WiFi has disappeared again.
This is not software, I firmly believe this is poor quality hardware or assembly - much like the graphics freezing issue others are experiencing. Don't waste time, energy and money, don't accept it and don't let it lie. Let Apple repair your WiFi card at their cost.
This is what I shall be doing again.
EU Directive 1999/44/EC holds retailers liable for all "non-conformities" which manifest within two years from delivery. Note this is retailers, not manufacturers. If you did not purchase directly from Apple, pursue the company you bought it from, not Apple. If outside the EU, look into your local equivalent regulations.
Here in the UK the Sales of Goods Act (SOGA) even exceeds the requirements of EU Directive 1999/44/EC.
SOGA provides cover for up to six years in England and Wales (five in Scotland). The act requires three things of sellers: the goods must be as described; they must be of satisfactory quality (determined by description, price, durability, freedom from minor defects); and they must be fit for purpose. In the event of a breach within five (or six) years, the seller must offer repair, replacement or compensation.
Go to it!

Wi-Fi: No Hardware Installed Problem - Macbook Pro

After connecting Wi-Fi and surf online about 20 minutes, Wi-Fi is stop. Can not turn on and turn off. It shows "Wi-Fi: No Hardware Installed". I shut down the computer. Leave about 20 minutes. Then power on the computer. Wi-Fi is working well again. But after surfing online about 20 minutes (Especially when watching streaming movie), Wi-fi is stop again. Problem is repeating. I have tried several way to solve by reading post. No way work to solve this problem. I have faced this problem since Snow Leopard, now on Lion. Still facing problem. If somebody know how to solve, Please..

Dear,
Had the same issue with my MBP (mid 2010) and tried everything.
The hardware test did not give any error and all kind of resets did not solved anything.
Finally, I just returned my Mac to the Apple store and got it back after 3 days and with a new WIFI card in it (and a bill of 250 €).
I'm absolutely convinced that there is a link between the upgrade to Lion and the 'broken' WIFI card but Apple keeps denying it.
So, Mr. Tint, no choice: bring your Mac to the repair shop and pay.

MacBook Pro 17" Mid 2010 wifi "no hardware installed" fix

Hello,
Wanted to share my "wifi: no hardware installed" fix for my 17" mbp. Story is short - some time ago I noticed that sometimes after sleep there is no wifi. I'm carrying my laptop with me every day in backpack, so it just won't connect to any known network when I open it. Only reboot helped. I tried all available solutions with no luck - no matter what I do, I must reboot it every time I need wifi. Last month it stopped working completely. First, empty wifi icon, I can't turn it off or on. Finally, after reboot it said "no hardware installed". Quick googling points to dead wifi card. So, I opened laptop to see what card I have to order it online. Guess what happen, when I assembled it back? It worked! But only while it was on a table. As soon as I took it with me - it stoped working. So, I opened it again, re-seated cable from m/b to wifi card and that worked again, until next trip in backpack. So, it seems this cable becomes loose and disconnect after some vibrations. Then I put two small pieces of rubber tape (used to seal windows, very soft) on each side of cable. It's high enough to keep connector in its place when you close cover. See attached pictures. Be careful and don't put too much here - otherwise when you close cover it will damage m/b and wifi card.
So, if you're carrying your mbp all the time in backpack and wifi sudden disappear saying "no hardware installed" may be this fix will help. Note, this fix only for mbp mid 2010. I have no idea, what happen in other models. And if you're not sure - take it to service.

After updating to 10.8.1 i can not connect to wifi no hardware installed , it says

When I installed the update to 10.8.1 there comes a message that there was a problem by installing.
Now i can not connect to a wifi network, when i click on the wifi at the bottom
No hardware is installed
Why is there no hardware installed?
Under 10.7 all was fine

I have MacBook unibody late 2008 with OS X Mountain Lion on board. Wifi stopped working suddenly and I spent about four terrible hours to solve a problem.
Actually, none of mentioned and googled advices helped me out to solve this issue with 'WiFi: No Hardware installed'.
Except one thing: using the wifi kext from the Snow Leopard. You may use utility and kext from here: http://rys.sommefeldt.com/2011/09/04/osx-lion-wifi.html
I hope, this can help.

Brand new imac i5 21.5" wifi says "no hardware installed"

I just bought a brand new imac i5 21.5 inches running osx 10.8.2 and minutes after having everything working, wifi stopped working and gave me a "no hardware installed" message on the wifi icon on the top right corner of my tool bar... I'm extremelly upset with it... can't find a solution anywhere. I tried to boot with wireless keyboard and mouse off and it didn't make a difference. Please Apple I need a solution! The computer is fresh out of the box! This is unacceptable.

Hi Michael Smith 677;
I suggest you take it back and allow Apple to repair it. There is no sense in you attempting to fix when it is brand new that is what they are there to do.

My WiFi is down and says ´´No Hardware Installed´´ and I´m not sure how to fix it. I´ve tried shutting it down and pressing P, R, Command, Option, but it only works sometimes, and as a temporary fix. What do I do?

My WiFi is down and the icon states ´´No Hardware Installed´´. Sometimes the WiFi will come back, but it will shut me out after an hour or two. I´ve tried shutting it down and pressing P, R, Option, Command while turning it on, but it only sometimes works and is a temporary fix. I´m studying abroad and there aren´t apple stores near me. I went in to one before I left, and thought the tech employee had fixed it, but I started to have the same problem here. How can I fix this?

WiFi: "no hardware installed" on Mac Mini, OS 10.8.5

I realize that there are many existing threads on this error message, but they all seem to be related to laptops with spesific affected hardware and not a Mac Mini. So:
I have just gotten my mid 2011 Mac Mini back from service. They replaced a fauly motherboard. It was in twice. The first time I got it back home I just had the time to upgrade the OS before it collapsed again. I took it back and they replaced the motherboard anew. The one they had put in apparently had problems.
Now after the second repair job the old problems are gone but there is no WiFi. "No hardware installed" it says.
My problem is that if I take it back and have it repaired a third time and it turns out that this lack of WiFi is caused by a bug in OS 10.8.5 and not by their repair work, I will have to pay for it. The hardware is under warranty but the OS upgrade I have done myself. The Mac didn't come with OS 10.5 when I bought it from them.
So how do I know if it is a hardware faul or not? I have booted in recovery mode but there is no hardware found there either. Tried various other tips like disabling Bluetooth, deleting the old WiFi setup from the network panel, resetting SMC and so on. (Resetting nvram does not help with network issues Apple say, so I don't know why that is adviced in so many threads).

So it went in for service and they couldn't find anything wrong with it. I tried everything before handing it in and rebooted without things plugged in and so on. But now it works. No loose parts either apparently.
So there we are. Everything is working fine again by itself. For now.
