Mac wifi turns on and off

Wifi is turning on and off on mac, why?

When I upgrade from Yosemite to El Capitan I started having Wifi issues.

My Wifi router is working great but Wifi on my Macbook Pro is unstable.

Is here any possibility to fix this problem?

MacBook Pro (Retina, 13-inch, Mid 2014), OS X El Capitan (10.11.1)

is the wi-fi turning on and off or is the signal dropping while you use it in the same place

in some cases updating your OS can improve HW issues, your sig has you on 10.11.1, you might consider 10.11.5

What does Wireless Diagnostics show?

Also try turning off Bluetooth.

If your Wi-Fi source is capable of generating a 5 GHz Wi-Fi network, try that to help avoid conflicts with Bluetooth.

Wifi is turning on and off.

Also when I don’t surf the internet Wifi is stable (mostly).

I have installed OS X El Capitan 10.11.5.

This problem occurred when I update from Yosemite to El Capitan.

I am having the EXACT same issue and situation as matusfromprievidza, and I’ve been trying to troubleshoot for some time now but haven’t found any lasting solution. Anyone know what I/we can do?

I can still experience some Wi-fi drops, but it seems that’s not software or hardware issue of my Mac.

In my case the problem was causing the Wi-fi router itself (or my internet provider).

I was talking to them about this and they told me it can be happening because of the old internet cables.

I live in Slovakia and optical cables are not yet standard so I still have just ADSL type of network (2.4GHz).

If you’ll still have problems with this, try contacting you internet provider 🙂

I’ve restarted and rebooted everything I can in my wifi connection, and I am still encountering the issue of wifi turning on and off and occasionally just staying off in which case I have to reset my mac to turn it back on. I think you are right, my only options left is to contact my internet provider like you mentioned, or go see someone in person with my mac for a possible fix if it is a software issue.

I’ll post an update when I have tried one or both of these things. wish me luck.

Wi-Fi is Off and Won’t Turn On Mac, Fix

Several users have said that they are unable to turn on Wi-Fi on the Mac, thus the Mac won’t connect to the Internet over Wi-Fi. The problem is that users find that the menu icons indicate that Wi-Fi is turned off and attempting to turn it on by clicking “Turn Wi-Fi on” does not work. In a way, it appears the Wi-Fi is stuck in the off position. This article explains what you can do when you cannot turn on Wi-Fi on your Mac.

Can’t turn on Wi-Fi?

• Turn off your Mac.
• Locate these four keys: Option, Command, P, and R. Do not press them yet.
• Turn on your Mac and immediately press and hold the four keys: Option, Command, P, and R.
• Keep holding them for about 20 seconds. Release them when your Mac starts up for a second time.
• Then release the keys. Test your problem again.

3. Safe Mode

Turn onSafe Mode. Test your Wi-Fi problem in Safe Mode. Then turn off Safe Mode (by simply restarting your Mac), then try to enable Wi-Fi again:

Follow these steps to Safe Boot your Intel Mac:

• Turn off your Mac.
• Turn on your Mac and immediately press and hold the Shift key.
• Keep holding the Shift key until the login screen appears.
• Then login, you may have to log in twice.

Follow these steps to Safe Boot your Apple silicon Mac:

• Turn off your Mac.
• Press and hold the power button until the startup options window appears.
• Choose your startup disk.
• Press and hold the Shift key and click Continue in Safe Mode.
• Then login.

If you are not sure if your Mac is an intel based or Apple silicon model, go to the Apple menu > About This Mac.

Restart macOS networking (AirPort) using Terminal

Try turning off and on Wi-Fi via Terminal. Here is how:

a. Open Terminal (Applications > Utilities). In Terminal, enter the following command and hit enter:

networksetup -setairportpower en0 off

Please note that your device name could be en1 etc. But this Terminal code will turn it off anyway.

Then enter the following command to turn on again:

networksetup -setairportpower en0 on

4. Reset Wi-Fi network settings

You may be unable to turn on Wi-Fi because your settings and preference files may be corrupted. Deleting them may fix it. When they are deleted, your Mac will automatically create them but you will lose your settings. This will rebuild your Mac’s network configuration. Here is how:

a. Go to the System Library folder:

• Open Finder and then click Go and Go to Folder, or alternatively press the Command, Shift, G keys together.
• Enter the following location and click Go:

/Library/Preferences/SystemConfiguration/

b. This will open a folder. Locate the following files (you may not have all of them):

preferences.plist com.apple.wifi.message-tracer.plist com.apple.nat.plist com.apple.network.identification.plist com.apple.network.eapolclient.configuration.plist com.apple.airport.preferences.plist NetworkInterfaces.plist com.apple.eapolclient.plist com.apple.IPConfiguration.control.plist

c. Move these files to your Desktop (create a folder and place them there). This will be your backup if this does not work.

d. Restart your Mac.

e. Then open the Network settings on your Mac (System Preferences > Network) setup Wi-Fi again.

5. Delete the Wi-Fi service and then re-add

Please follow the steps below to do this:

a. On your Mac, go to System Preferences > Network.

b. You will see a list of services, select Wi-Fi, first disable it by clicking the more (…) icon below the list of services and selecting the “Make Service Inactive” and, after disabling it, we will delete it. Select Wi-Fi and click the remove (-) icon to remove your Wi-Fi service. Then click Apply.

c. Now restart your Mac. Go to the Apple menu and Restart.

d. Now, again, go to System Preferences > Network. Click the add (+) button. A popup will appear saying “select the interface and enter a name for the new service”. Click the Interface options and select Wi-Fi and this is optional but you can edit the service name. Then when you are done, click the Create button.

e. Then click the “Turn on Wi-Fi” to see if it is working now.

6. Hardware problem?

If you are having this issue, a hardware issue may be causing your problem. For example, you can see a message saying “no hardware installed“. Or maybe, the network card has failed. Your Mac’s System Information can give you more details about your Wi-Fi hardware. Simply open the Utilities folder, and click System Information. In System Information, click Network and Wi-Fi.

why does my wifi keep going off and on?

I use a Mac, the internet keeps going off and on, the wifi says looking for network, when this happens anything I’m working on in Sarfari, Firefox or Google stops until its back on. AT&T just replaced the modium but it didn’t help. I would think it is my computer but my husband’s Mac does the same.

Constant WiFi drops that are fixed by restarting My WiFi connection keeps dropping every few hours. If I restart the computer it comes back and works perfectly, so it doesn’t seem like a problem with the WiFi itself. It’s incredibly annoying. What can I do to fix it? (I tried to get a report with wireless diagnostics but it failed)

Wifi turns on and off The wifi on my computer keeps toggling from off to on. As if I’m switching it back and forth. Or won’t stay connected long enough to connect to our router. Its helped in the past to shut the computer down for a while, but that didn’t work anymore. Thanks.

Ny big Microwave interferences around?

I’ve been debugging a problem with my VPN client constantly reconnecting, along with poor WiFi performance. After much digging, I came across an excellent article — although written for Yosemite and iOS8, it still seems to be relevant to Mojave, especially with a newer WiFi chip in the 2018 MacBook Pro. https://medium.com/@mariociabarra/wifriedx-in-depth-look-at-yosemite-wifi-and-awdl-airdrop-41a93eb22e48

The author wrote a program that essentially just issues a command and keeps it enforced. You can try it manually in a terminal window: sudo ifconfig awdl0 down

To reverse the command, type: sudo ifconfig awdl0 up

He gives a great technical explanation, so I won’t repeat it here. The command disables a virtual network interface that’s used for ad-hoc WiFi by features like Airdrop; I personally won’t miss them. So far, I’ve gone from losing my connection 20 times an hour to being stable for 3+ hours.

Hello, thank you for your response. My Mac is located next to the room with the At&t Gateway, which I replaced yesterday, thinking it was the problem. My husband’s is connected by Ethernet since his office is farther away. At&t says my Wifi is working correctly, we are fortunate to have the fastest internet available in our neighborhood, and the source is right outside our house.

I read the article you attached, and could pretty much understand most of it, I’m not a computer wiz when it comes to the technical stuff. I turned off Airdrop, unchecked Wake for Network Access, and tried to download the WiFriedX, but didn’t have any luck. I also ran a report on the wifi that was sent to Apple.

I’m am not familiar with using the terminal window. I think I have been there on support calls to Apple but don’t remember how to access it.

According to what I read it sounds like the Mac has conflicting issues with the items on my wifi. With the new Gateway At&t has an app that allows me to see the items on my wifi, there are 21 if you can believe that. It lists my Macs, Ipads, Iphones, Romba’s, Tv’s. Its amazing how much we rely on Wifi now adays. Do you think it is all the items on the wifi that is causing the problem? Will the fix you listed with the terminal window fix it do you think?

Thanks again for your time,

How to Toggle WiFi On and Off with a Keyboard Shortcut on Mac

wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. To create this article, volunteer authors worked to edit and improve it over time.

Do you find it annoying to have to navigate to the WiFi icon every time you want to turn off the WiFi on your Mac? Fortunately, there’s an easier way. By setting up a keyboard shortcut, you can turn your Mac’s WiFi on and off by pressing just one key!

Creating the Action

Make sure the top section is correct on the right: Workflow receives no input in any application .

Copy and paste the following script into the section of “Run Shell Script,” substituting “X” with any number that you found the WiFi port to be earlier. The script is: networksetup -getairportpower enX | grep «On» && networksetup -setairportpower enX off || networksetup -setairportpower enX on.

Click on Run in the top right corner. See if your WiFi turns off. You might need to wait a few seconds. If it works, click on the X and save the action, and name it something obvious like “WiFi Toggle.” Then, proceed to the next section.

Creating the Keyboard Shortcut.

Click on Services . Scroll to the very bottom until you find the action that you just created.

Type in your shortcut. You might use Ctrl + ⌥ Opt + ⌘ Cmd + W . Control Option Command W). Make sure the shortcut is not a common shortcut.
