My wifi connection says no hardware installed

I cannot connect to wifi. The icon says no hardware connection

Welcome to Apple Support Communities
Reset the PRAM > http://support.apple.com/kb/HT1379 After that, do a SMC reset > http://support.apple.com/kb/HT3964
If it doesn't work, hold Command and R keys while your Mac is starting to start up in OS X Recovery, and press the Wi-Fi icon at the top right corner. If you can select a network, reinstall OS X, and if not, take the MacBook Air to an Apple Store or reseller because the Wi-Fi card needs to be replaced

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

Hello Harrisonhcue,
I would be concerned too if I was getting the message "no hardware installed" when trying to use Wi-Fi on my MacBook Pro. For a message like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My macbook pro 15inch running on maverick when i try to click on wi-fi says no hardware installed please help i need wifi and and under network staus wi-fi is fail and under network airport is not connected can anybody help the wifi icon has a x and does

my macbook pro 15inch running on maverick when i try to click on wi-fi says no hardware installed please help i need wifi and and under network staus wi-fi is fail and under network airport is not connected can anybody help the wifi icon has a x and does not even let me turn it on

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.
If this method doesn't work, check the webcam that will tell the problem is on the iSight & WiFi cable. If your webcam is ok, then it'll be the WiFi card problem. Hope it can help ;-)

Wifi on my mac OS X 10.9 running marvericks its saying no hardware installed, what could be the solution?

https://discussions.apple.com/discussion/create.jspa?containerType=14&redirectUR L=%2Findex.jspa&question=true&containerID=2998&subject=wifi on my mac its saying no hardware installed, what could be the solution

There are a number of possible reasons for that message, including defective hardware that only Apple will be able to fix. The steps you can perform yourself are as follows:
1.
Perform an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
2.
NVRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

Why does my airport wifi icon now say "No Hardware installed" It has been working for ever

Why does my airport wifi icon now say "No Hardware installed" It has been working for ever

This message comes up when your Mac no longer recognizes that there is an operational AirPort card installed. This can be due to a number of reasons, including card or antenna cabling failure.
You can try either a PRAM or SMC reset. Which you choose will depend on the exact model of your Mac, but most likely, a visit to your local Apple Store is in order.

When Mac Pro pro stops having wireless and says no hardware installed what does that mean. I try to turn it on and it doesn't work. Does that mean it dies. IT is a macbook pro from June 2009

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?

This worked and solved the problem.

Wifi icon showing "No hardware installed"

The Wifi icon on the bar is showing "No hardware installed". Could it be the network adapter has broken and need replacement? Any troubleshooting I can do before sending it for repair?
Jesper

Doesn't appear to have a card installed that is being detected. Mine shown below.
Try the SMC reset suggested by leroy's post.
Reset SMC
If that doesn't work, if you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing.

AirPort says 'No Hardware Installed' after replacing it ?

I have a MacBook Unibody model of 2008 and i was using it when it decided to crash. I restarted it and the wifi wasnt working and it told me No Hardware Found. Since here we don't have any apple stores and it was out of garantuee, i decided to buy a new one and fix it myself. However after replacement and a formating it, the was telling me the same thing. Any solutions ? thanks a lot

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. Reset the NVRAM.
3. Reset the System Management Controller.
4. Boot into Recovery. In the OS X Utilities screen, select Get Help Online. A copy of Safari will launch. Test. If Wi-Fi works now, quit Safari and 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.
5. Take the machine to an authorized service center for testing.

Brand new Imac and wireless is saying no hardware installed? really confused as it was working fine yesterday, brand new Imac and wireless is saying no hardware installed? really confused as it was working fine yesterday

Hi Guys, I juts bought a new Imac and jad it connected to my wireless router yesterday but now when i click on the wireless button on the top screen, it comes up saing wireless hardware not installed, have any of you had this problem? Thanks Tracey

You can quickly see if there is a problem in reporting the AirPort card by going to the apple in the upper left corner, About This Mac, More Info, System report and look at the information on Hardware and the AirPort report...make sure it is not indicating a fault.
If all looks ok, try removing the network information and reentering it and see if the AirPort responds.

HT1338 Mac Pro WiFi suddenly states "No hardware installed" but it worked yesterday.

Anybody else seeing this recently? Hopfully it's not a hardware issue.

All kinds of weird fixes for this issue have been reported, most of which make no sense. I think it's usually or always caused by a hardware fault, which may be intermittent — something like a loose connector or a failed solder joint. Almost anything might seem to fix it, at least temporarily. In some cases, a software or firmware bug may be involved.
The Apple Hardware Test doesn't find anything, as usual.
To rule out everything but a bug or a hardware fault, take each of these steps that you haven't already taken:
1. Make sure all available updates are installed.
2. Reset the NVRAM.
3. Reset the System Management Controller.
4. Boot into Recovery by holding down the key combination command-R at the startup chime. In the OS X Utilities screen, select Get Help Online. A copy of Safari will launch. Test, then reboot as usual.

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.
