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.

HT1338 After i upgrade my Macbook to OSX 10.9.1, it complaint that my "WiFi:No hardware installed", what could be the problem ? Appreciate your advise.

After I upgraded my MacBook to OSX 10.9.1, the wifi does not work only the ethernet port works.
I check the WiFI setting, it complain with error message as follows "Wi-Fi: No hardware Installed".
Pls advise what is wrong and how to resolve.
Thanks

First thing I'd do is shutdown the machine fully (that means use 'Shutdown' not 'Restart' from the  menu), then power on.
If the problem persists, reinstall OS X from the recovery menu (power on, immediately hold down 'command-R' and choose 'Reinstall OS X' from the panel menu).

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

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.

Hello, I have an iPod touch 5th gen and it continuously loses its wifi connection and also it doesn't show the usage status in the settings. It's got the 6.1.2. Software. Any idea as to what could be the problem?

I've recently updated the iPod and also restored it. But the problem with the wifi connectivity still prevails. There is also a problem with the battery. After having charged it completely, the usage still doesn't appear in the settings. Any opinions as to what could be the probable problem?

In settings>general>usage it shows --
And yes, it shows the same problem when connected to other networks.

I have a 13 inch Macbook Pro. I have bought it just 5 months back. All of a sudden, i am unable to turn the mac on. It doesn't even get Charged. What could be the issue ?

If you're unable to turn it on, let alone even charge it then it definitely sounds like a battery issue to me. I'd wait for someone else to reply just to be sure but I think somehow the battery by the sounds of it must have died. However, I could be very wrong.
If you're still under applecare which you should be then it should be an easy free fix. Hope this helps!

HT1338 I have version Mac OS X 10.5.8. I no longer get software updates. What could be the problem?

I have version Mac OS X 10.5.8. I no longer get software updates. What could be the problem?

No problem. You have to pay for the next upgrades, just like you paid for the last one.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?

You should boot from the Installer DVD by holding down the C key during start up until the Apple logo and spinning cog wheel appears. Allow plenty of time for the installer to appear - it can take several minutes when booting from a disc.
I suggest not doing this unless the Apple recommended method (starting by double-clicking on the
Install Mac OS X icon while booted up normally) fails.
There are several reasons for this:
The Apple method performs a check of the DVD's integrity before starting up from it. This can't be done if you start up directly from the DVD.
The Apple method "phones home" using the current OS's network settings to check for updates to the incompatible items database included on the DVD & writes a lot of pre-install data (the 'Mac OS X Install Data' stuff) to the HD before restarting automatically from the DVD to finish the installation. This may not work as expected if you start up directly from the DVD.
The pre-install data on the HD speeds up the installation process (because running the OS from the HD to build the data is faster than doing that while running from a DVD).
The Apple method makes it possible to "gracefully" cancel the installation before the automatic restart occurs without leaving the existing OS on the HD in a corrupted, "half-installed" state unable to restart the Mac. This sometimes happens if the installation process hangs & one has to force-restart the Mac to recover. As long as this occurs during the "pre-install phase" before the restart, the existing OS should remain untouched & intact.
Also note that the Snow Leopard installer is quite a bit more sophisticated than the previous ones like for Leopard or Tiger. It automatically performs the equivalent of Disk Utility's Verify Disk step before beginning the installation & performs more checks during the installation process (including checking the pre-install data for errors). It is usually not necessary to remove the "Mac OS X Install Data" folder after a failed installation, which may just cause the process to take longer on subsequent attempts, but if nothing else helps it is certainly something worth trying.

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 ;-)

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.
