My Macbook Pro is not connecting to the network and reads no airport card installed

This morning all of a sudden my mac has no network connection. When I run the cursor over the area to select it reads that no airport card is installed. I was online last night nd everything was fine. Thank you in advance for your help.

I am having the same problem. First on a new ViewSonic, which I sent back thinking it wasn't working. Now the same problem on my new Powerbook Mac with a new Epson projector. Apple support hasn't been helpful.

My MacBook pro will not connect to the Internet through wifi yet all other devices do

My MacBook pro will not connect to the Internet through wifi. I have several other wifi enabled devices and they are all connected to the Internet just fine... What could/would cause this?

Disable your AirPort and enable in a second. Or check, maybe you need to type in correct digits in; Settings/Network/Advanced/Configure...

My Contacts app for macbook pro will not connect with my yahoo and keeps asking for password.

My Contacts app for macbook pro will not connect with my yahoo account and repeatedly asks for yahoo password, any soliutions to this?

This is due to a change in Yahoo's security settings. You need to go into your Yahoo account settings and create a special App Password, then use that password in Contacts to access your account. Same goes for Calendar.

My Macbook Pro will not connect to the internet or bring up Safari!

For the past couple of weeks my Macbook Pro has been having issues connecting to the internet and when it is connected it won't bring up Safari "You are not connected to the internet"
I use the correct password for my wireless internet and it still won't connect. I deleted the airport in system preferences and then made a new one. It connected for a few minutes but then disconnected and just shows an explanation point over the airport sign at the top of my status bar.
PLEASE HELP ME.
I run a business and not having access to the internet on my Macbook is very very stressful.
I brought the Macbook into the Apple store but of course it works perfectly when I bring it in there... HELP

I also just realized it's also saying under the Airport status in System Preferences that the "AirPort has the self-assigned IP address ###.###.##.### and will not be able to connect to the internet."

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning not to screw up. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Why is my MacBook Pro safari not connecting to the internet?

The past week I have been trying to use Safari on my MacBook Pro but it keeps saying Safari can't verify the identity of the website. I am not sure how to get rid of the popup, so I can continue to use the website. What do I need to do to resolve this?

Which website? Is it one in particular, or dose it appear on every website?
When you open Safari, does it always open with this site?

My MacBook pro will not connect to the internet, be it via the airport or ethernet at any location.

I have been on the phone with tech support, and have been to the Apple Store 3 times already. Each time I have brought the computer to the store, the internet will work. The workers say the store is 'magic.' However upon leaving the Apple store, the internet will not work be it at Starbucks or home. On my last visit to the store, they backed up everything on Time Machine, cleared the computer, and reinstalled OS, but I still cannot connect.
I'm at my wit's end and could use any help available. Thanks!

Turn off your Firewall, to eliminate that as a problem. System Preferences > Security > Firewall
Check to see if the router you are plugging into doesn't have MAC filtering activated.
Make sure your IP is not the same as another computer or router on your network.
If you have manually put those details in, see if you can set it to "Using DHCP"
System Preferences > Network
Are you using a Proxy? Make sure that is turned off in Advanced.
Is firefox / Safari in the Preferences under Advanced & Network - set up correctly?

My Macbook Pro will not connect to the internet.

Randomly, my Mac stopped connecting to my wifi network 2 days ago and now it will also no longer open safari or other internet based apps.
My network icon is always 'searching'. I can find my network occasionally and the status will be connected, but the icon remains searching and no internet is let through on to my mac.
I've tried the usual diagnostics but it replies my password or network name is wrong although it is correct. When I look in 'airport', nothing is found. No addresses are in my TCP/IP information, nothing in my DNS tab, no proxies boxes selected.
I have powered down my mac and routed numerous times and turned wifi on and off no end. All other apple hardware connects well.

When you see an exclamation point in the Wi-Fi menu, from the menu bar, select
 ▹ System Preferences... ▹ Network
Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

My macbook pro will not connect to the internet, help pleaaaase?

I have literally been to countless forums and nothing has worked. I restarted the router for the internet, but every other computer in my house is connecting to the internet just fine. I don't know what to do, and this is incredibly frustrating. Can anybody help me?

Macbook Pro is not recognizing remembered wireless networks and does not sign on to them automatically anymore.

When trying to connect to my home wireless network, my computer doesn't recognize my network, or any network as being accessed before. It doesn't remember any networks. I even went into the advanced settings and made sure to check the box that makes it remember networks, and it still doesn't remember them. I am able to connect to my home network manually, but it will not automatically connect when I open the lid after it being closed, or when I turn off the wifi and turn it back on. What should I do?

Thank you for your suggestion, and I have, (I actually tought that may have been the problem initially) unfortunately it was not successful. But I did go onto the Keychain Access and fixed the passwords in those and then deleted and reissued my prefered networks and it happened to work out just fine.
Thank you again, clintonfrombirmingham!

My printer will not connect to the network and i cannot find drivers for it

I just installed Win 10 64 bit and I lost all connection o my printer it is saying I am on another network and each time i try to load the drivers for it it fails

Hello vikagor,
Thank you for visiting Apple Support Communities. It sounds like you are talking about cellular data not phone calls that's the issue.
For troubleshooting cellular data issues please see:
iPhone cellular data connection issues
Note the first symptom is, "No connection over cellular network, but works over Wi-Fi".
Take care,

New MacBook Air having trouble connecting to the network and staying connected

I have an iMac as my prime and a MacBook Air as my remote. My network is all Apple. If I close the lid on my MacBook Air it immediately disappears from finder as a shared resource. However, if on first run though I put it to sleep and then close the lid, it will remain on the network as a shared resource. From hereon in, I can just close the lid to put it to sleep and its fine.
If I restart either computer or both computers, I have to go through the first run routine again. What makes matters worse is I’m trying to do an 11pm Retrospect backup of the Air and if it gets lost from the network Retrospect is unable to find the device. I have to do a locate in Retrospect and then let it do its backup.
I think this putting it to sleep on first run and then closing the lid to maintain stability is just a workaround I accidentally discovered. I don’t think it should be working like this. I think if I just close the lid and let it sleep that way on first run it should remain on the network as a shared resource and I should continue to see it on my iMac in Finder but this isn’t the case.
I’m really looking for opinions on this issue, if others have experienced this and is there anything that can be done about it. I’ve got mixed messages from Apple Tech support but Retrospect tech support said I’m doing everything right. This to me seems like a bug in probably the software. The machine runs fine except for this one little quirk.
Kerry

Yes its ticked. I’ve worked at this for two weeks and have gone through every iteration I can think of. Apple said that it is normal that the lid has to be open to have the shared resource but as long as on first sleep I put it to sleep first then close the lid it remains in the iMacs finder Window as a shared resource. And I can open and close the lid from thereon in and it is always there as a shared resource and Retrospect can locate it for backups.

Macbook air will not connect to the wifi network

I recently had to replace my wireless network router and now my macbook air will not connect to the network. it worked fine with the old wireless router. Now, i get a "unable to join wi-fi network" message. The network ID (SSID) and password (WPA) are the same as before. I try to manually enter the password, but continue to get the previous message.
Any help in figuring out how to correct this problem is greatly appreciated.
Also, I have several PCs in the house that have had zero problems connecting to my wireless with the new router. What am I doing wrong?

Hi,
Ever since did the last airport utility update this has been happening.
I believe the airport utility update is solely a software update. Repair permission and repair disk (boot from your installation disk A) may help.
Other wise, http://osxdaily.com/2009/12/22/mac-wireless-problems-guide-to-troubleshooting-ai rport-wireless-problems-on-your-mac/ may help, too.
Cheers.

Um okay. And? What have you done to try to fix it? What error messages are you getting? Do you use WiFi or Wired connection?
