I have a MacBook aluminum unibody (late 2008) with OS 10.7.5. This morning when I turned it on, the wifi icon in the Menu bar was 'empty' (i.e. no bars) - clicking on the icon gave me the info that 'wifi is off' - I clicked 'turn wifi on'- nothing happened. I opened System Preferences - Network. Status showed Wi-Fi is off. I clicked on the 'turn wifi on' button - nothing happened. I restarted the MacBook - repeated the above steps - six times now - always the same result :-(
6. Once restarted, go back into system preferences, into network, and use the + button to add a wifi connection back into your computer. With any luck, you will be able to click on 'Turn wifi on' and it will actually work!
How To Turn Wifi On For A Mac Book Pro
To establish whether the problem lies with your router, you should turn it off and on again. To powercycle your router you need to disconnect it from power for about 30 seconds, then plug it in and turn it back on.
Have you tried switching from DHCP to manual setup? Sometimes when i've put my MBP to sleep and wake it up the connection is lost and the only way to get back up is turn the WiFi off (i do this through terminal for speed):
One thing I noticed recently on my own network was that I was using a 40MHz band but Apple don't actually support that band, just 20MHz bands. I switched my wifi at home but haven't been using it long enough yet to say if it has made much difference.
You could also get a utility from the Mac App Store to investigate your wifi network. As the first google result I got(wifi explorer): -explorer/id494803304?mt=12but I haven't tested it or any similar programs myself so I can't say for sure how helpful they would be.
Make sure the name of your WiFi network (the SSID) is unique in your area and that you have WPA2 turned on. Otherwise your laptop could get confused trying to connect to another router with the same name. And of course verify that you have adequate signal strength for communication between the router and the laptop.
Note that you should be sure that you want to turn on Internet sharing. If your Mac is connected to a network, turning this on may affect the network settings of other computers and perhaps even disrupt the networks.
Quick tip: If Wireless Diagnostics turns up empty, now's a good time to set up Wireless Monitoring. When the tool finishes, select Monitor my Wi-Fi connection in the pop-up that shows, and then click on Continue. This will produce a log that could help a technician understand your Wi-Fi problems.
1. For the PRAM/NVRAM, start the computer and after you hear the startup chime, hold Shift, Control, and Option keys while you press the power button on your Macbook for at least 10 seconds.
If you enable Wi-Fi Calling and connect to a Wi-Fi network from a Wi-Fi Calling enabled device, information about the country where your network connection is made, based on your IP address (or cellular network if applicable), may be sent to your carrier for billing and service availability purposes. If you do not want to share this information with your carrier, you may turn off Wi-Fi Calling on your iPhone and paired Apple Watch by going to Settings > Phone, and tapping to turn off Wi-Fi Calling (for iPhone) and turning off Calls on Other Devices (for your other devices, including your paired Apple Watch). To turn off Wi-Fi Calling on your iPad or iPod touch, go to Settings > FaceTime, and turn off Calls from iPhone. To turn off Wi-Fi Calling on your Mac, go to FaceTime > Settings, and turn off Calls from iPhone.
In order for your carrier to complete short code calls (calls to abbreviated numbers that provide access to public services) via Wi-Fi or cellular data, Apple must provide the city from which the call is placed to your carrier to help them properly route the call. If you do not want to share the city you are calling from with your carrier when making short code calls, you may turn off Location Services for Wi-Fi Calling on your iOS or watchOS device by going to Settings > Privacy & Security > Location Services > System Services, and tapping to turn off Wi-Fi Calling. You can turn off Location Services for Wi-Fi Calling on Mac by going to System Settings > Privacy & Security > Location Services, then clicking Details next to System Services and deselecting Wi-Fi Calling. If you turn off Location Services for Wi-Fi Calling, your device will not be able to determine or send the city you are in to your carrier when you dial a short code number for a Wi-Fi call and as a result your carrier may not be able to properly route or connect your call.
I bought a Asgard (seems operates from HongKong) 2TB NVME PCIe M.2 SSD that I installed into mackbook pro 15in mid 2015 with sintech adapter for conversion to MacBook AHCI controller. The disk utility does not show this SSD. Later I installed in same way another Sabrent SSD 2TB it worked fine.
Resetting the NVRAM is a lot easier than you think. First, shut down the Mac and immediately after you turn it back on, simply press and hold Option + Command + P + R on your keyboard for about 20 seconds. This will reset both the NVRAM and PRAM. You can confirm this when the Apple logo appears and disappears for the second time while booting up.
The procedure is a lot easier on Mac Desktops with or without the T2 chip. Simply shut down your Mac and unplug the power cord. Now, wait 15 seconds and plug the power cord back in. Wait for at least 5 seconds before you turn on your Mac again.
Like with any computer, you may sometimes find issues like Mac connected to WiFi but no internet or your Mac disconnecting from WiFi randomly. When your Mac disconnects from WiFi, it often reconnects automatically. But in some cases, it needs you to turn it off and on again.
"Wi-Fi: no hardware installed" is a macOS error that can appear when the computer returns from sleep. The error occurs when the device is unable to connect to Wi-Fi. However, restarting the computer or laptop often solves problems with the connection. If it doesn't help, we suggest running quick maintenance.
No specific key combination is required to perform the NVRAM reset on M1 Macs. The NVRAM is examined at system startup and reset if necessary. To allow the OS to check the NVRAM, just turn off your Mac, wait a little bit, and then turn it on again.
Return to the left-hand side of the Sharing window and tick the box next to Internet Sharing to turn it on. A confirmation box warning you are enabling access to the network will appear, which can be accepted by clicking Start.
The setup process can also be adjusted for different situations, for example setting it to share an Internet connection from a Wi-Fi network through a Mac's Ethernet connection can effectively turn a Mac into an access point for an Internet-less wired network.
Previously I used my Kindle PaperWhite to get onto the Internet via my iMac using the procedure described in this article. I stopped using the Kindle for a while then tried to download an ebook I bought recently but I couldn't connect. I used the described feature but a Kindle message says Peer-to-peer wifi networks are not supported on Kindle. Try connecting to another network.Do I need to change the procedure for the Kindle, or has Amazon changed how it connects to the Internet?I tried asking this question on a Mac forum but no one was able to help. I have my fingers crossed either the author or some knowledgeable reader will know the answer.Thanks.(I use Ethernet and a router for the iMac to get onto the Internet no problem.)
how do I turn off the repeated WiFi calling notification on macOS 10.15? To set up your Mac for WiFi-calling on macOS 10.15, the first thing to do is to get a hold of every Apple device in your Apple ecosystem and turn off the Wi-Fi calling feature in each of them.
How to turn WiFi on and off can vary by make and model of laptop, but these common ways to enable WiFi on your laptop computer should help you. If you can't find your answer here, refer to your computer's user guide or support center.
Another way to enable WiFi is by pressing the "Fn" key and one of the function keys (F1-F12) at the same time to toggle wireless on and off. The specific key to use will vary by computer. Look for a small wireless icon as shown in the below example image of an F12 key. This key sometimes also has an orange LED on it that will turn on when WiFi is enabled.
After verifying that your WiFi button is switched on, consult your users manual to enable WiFi in the computer's settings. You will often find this is in a section called "Network Settings" or just "Wireless Settings." Once this is turned on, try connecting your device to WiFi.
On the subject of Bluetooth/Wi-Fi, I came across an issue whereby Wi-Fi on a MacBook was so slow it was totally unusable. After much troubleshooting and looking for solutions on the web involving deleting preferences etc it turned out that when I turned off Bluetooth Wi-Fi was restored in that it was fast and useable.By removing the items that were paired with the MacBook (AirPods and Microsoft BT Mouse) the problem not apparent even with Bluetooth turned on, indicating a paring was the problem. By re-pairing the items one at a time it became evident the Microsoft BT Mouse pairing was the cause. So simply not using/pairing the MS Mouse resolved the problem.The moral here is try removing Bluetooth pairings before you get too involved in changing the system settings/preferences etc.
