My new Macbook won't connect to my wifi network - it keeps saying "password incorrect" - but I've tested it on my phone and works fine, I've checked the password I enter is correct digit for digit - what could the problem be?

you need to open the keychain access located in your utilities folder in the applications and once in the keychain on the left side click on the words system at the top and in the lower section click on passwords
next look in the striped area for any passwords that say airport network password next to kind and highlight those and hit delete on the keyboard to remove them from the keychain.
once you remove all of these airport passwords, quit the keychain
turn wifi off then back on, select your wifi network from the list and enter the password telling it to save to keychain this should resolve your issue!

  • New Macbook won't connect to existing network

    Hi there,
    I've just got my new macbook, and it won't connect to my wireless network. It comes up with an error message saying it cannot connect to the network. There's no hint of what the problem is. I have another laptop which connects to the network fine. Is it a password issue? And if so where do I go to change the relevant Airport settings?
    Thanks
    J

    The System Preference, Network, is where you change these things. However, it will only ask for a password when you try to connect, and it needs one. If it didn't ask, the network doesn't have a password. If you tried to enter one before, you can try deleting the Keychain that holds the wireless password. Open Keychain Access from the Utilities folder. Look for your network name in the list of items and delete the one with that name. If you have more than one, that may be the issue. Just delete them and start over trying to connect. Otherwise...
    We need to know more about the wireless network. Open, WEP, WPA? Type of router? What are the router settings?
    What are the MacBook settings for the Airport Network settings? Is it set to join automatic or preferred networks. Try adding your network as a preferred network and try that.
    The following are things that may work. Sometimes preference files prevent things like this, even on a new MacBook.
    There is also a preference file, /Library/Preferences/System Configuration/com.apple.airport.preferences.plist that controls some of the global Airport items. Try moving it to the desktop and then open system preferences and re-configure the network settings. Also there is preferences.plist. It has all of your network configurations and locations. If you move it, you'll have to add all of your network interfaces back into the Network Port Configurations and any Network Locations you may have made.
    You can always move them back if it doesn't help, but you'll have to overwrite the new ones that were created. You must be an admin user to do this.

  • Ever since my update to Mavericks, my Mac mini won't connect to my wifi network. I reset SMC and still nothing. The error message reads that my WiFi network could not be joined, yet my iPad and Macbook can connect fine. Any help here would be great.

    I recently upgraded to Mavericks on my macmini and suddenly it won't connect to my home wifi network.  It says I need to move closer to my router whioch is really close and it worked fine before so I doubt this is the issue.  Also, my IPad and Macbook connect just fine to the network, so it seems like its localized to my macmini and now funny enough my IPhone.  I tried reseting SMC and PRAM, but this didn't help at all.  Any helpful suggestions?

  • IPhone 5 won't connect to any wifi networks

    I have had my iPhone 5 for aabout 3 months or so. And a few days ago, it stopped wanting to connect to wifi. I have tried connecting to other wifi networks, so it's not just our router. I have also tried turning LTE off, connecting, and turning it back on. That worked for a few minutes, then stopped. I have tried forgeting the network, and reseting my network settings. Nothing is working. Thanks.

    No, not yet. I've decided to just send it in to apple sometime soon.

  • Macbook won't connect wirelessly on home network

    Hey guys,
    I see that a lot of you are having the same issue I am. I have a Macbook that I got the summer of 2008. Up until Thursday, it would connect wirelessly to my E-wire router and network just fine. Then it quit. Later that night, I went up to school for a class, and it connected just fine to the wireless network up there, but will not connect wirelessly to my home network. I have since gotten a new router (Netgear) and reconfigured everything (again), including security and all updates. Airport shows that I am connected to my network, and I can load web pages when I am plugged into the router via ethernet cable (as I am now) but when I try to launch Mozilla or Safari wirelessly, I get the "Server cannot be found" error message.
    I am connected to my network, I have tried shutting off Airport and restarting it, as well as quitting my browser and reopening it, and rebooting my Macbook all together. And I also went in and manually entered my IP address, which is what allowed me to connect to the network via ethernet cable in the first place.
    Any theories why my Macbook (which is newer) won't connect wirelessly whereas my roommates older Macbook doesn't have any issue connecting wirelessly from right next to me? And I know that it's not an issue of too many people trying to be on the network at once, since it's just the two of us at most, and I'm the only one here right now.
    Any thoughts or suggestions would be appreciated.

    Is your router a model that supports a/b/g/n? If you turn off N will it work? If your N is setup at 40MHz slots it may not work as well. Can you take your wireless router somewhere else for testing? I assume you might have some issue where you are at with your Mac and that router. When you open Apple Menu/About this Mac/More Info../Network/Airport does it show your network there? From a working machine can you see your Mac from your router web interface? FYI if your router was an Apple product(Airport Express or Airport Extreme/Time Capsule) you could see all your wireless clients via the Airport Utility, even signal strength and connection speed...

  • New MacBook Pro not connecting to MOST wireless networks

    Well I'm another loyal sufferer, 10.5.3 did nothing to solve the problem. After reading a bunch of posts however I think i have a bit of a unique situation..
    I'm staying at a condo for the next two weeks without internet, so i poach it from my neighbor, it's fine he said i could. I had a PC and that connected fine, fast too, when i got my mac it worked for a few days then crapped out, gave me the "self-assigned ip address' message of death. I brought my Mac to work and it worked fine on the company's internet wireless (it's an 801.x security) so after work i took it home and it worked for a day. The next morning, same problem.
    I took it to starbucks, said it was connected but wouldn't open any pages in firefox and wouldn't connect to messenger. Back home now it says i'm connected, I can get into the router settings and play around with it, nothing has worked thus far. I did a ping test and it's working fine, what's the problem?
    For the record i have tried the following:
    turning airport on and off then restarting
    Clearing airport preferences
    removing and reinstalling the OS
    clearing keychain
    trying every possible advanced option, manually entering IP's etc.
    doing the safe boot, restart and normal boot.
    I hear switching the router to 'g' only is the way to do it. I'm going to try that tonight because right now I'm just concerned about my internet connection at home, it works fine at work.
    Any new insight is greatly appreciated! I'm dyin' without it!

    You probably connected but failed to get an IP address. If you have other network devices turn them off, restart the router and see if you can get access to the Internet then. Otherwise click on the network diagnostics button (or which ever appears in Safari's failure) and see if it'll give you clues.

  • My MacBook won't connect to my wifi

    II've recently got a new bthub5. Since then my Mac won't connect. I've gone into system preferences but there's no AirPort only Ethernet not connected. And it also says cable unplugged. My mac has worked since the new hub but now it isn't. I'm very close to the hub. All other devices work. Even bt vision.
    Can an anyone help please?

    Remove all the old wireless names in the Macbook.. clear out the whole lot.. reboot the laptop and scan again.
    No luck reset the wireless in the BThub to fixed channel, short name no spaces and pure alphanumerics. No security just for a test. Can the Mac now find it.. if not it is incompatible.

  • My iPhone 5S can't find and does not connect to wifi networks. Occasionally will connect for a few minutes but then drops  and won't connect or find wifi network again

    Any ideas why my iPhone 5s won't connect to wifi networks. Sometimes does find the networks and others finds them, connects for a few then drops

    You do not say if you tried any diagnostic steps yet. The first thing to do is to do a reset or reboot of the phone. This does not erase anything on the phone and is akin to completely shutting the phone off and then a fresh reboot.
    First close all apps - double click on the home button and whisk away the apps toward the top of the phone to close the app.
    Now press the home button once to go back to the regular menu screen
    No press and hold the home button and the sleep/wake button the the top right side together for 10 seconds. The phone will turn off and reboot.
    See if that fixes it.

  • New iphone 4 working fine,then just went dead this morning. Its been charging all night. what's the problem?

    Just got iphone 4 on tues.  It has been working fine. Made 1 phone call this morning. 30 minutes later tried to use the phone again and it would not turn on. What could be the problem. Phone was charging all night.

    Sounds more like it might be frozen up.  Have you tried resetting it by holding the home button and the sleep/wake button for ~10 sec?

  • My iPad 2 won't connect to Public Wifi Networks

    So a few weeks ago I was at a cafe and tried to connect my iPad 2 to the wifi network of the cafe with no avail. I have tried rebooting multiple times, resetting network settings a couple of times, have tried most about anything but my iPad will only connect if I'm standing next to a router. Even then the signal that it's receiving it's not full. I don't know why this is happening please can someone help me out? It's really frustrating!!!

    Have you tried ....
    Rebooting your router?
    Turning WiFi off and then on again?
    Settings>WiFi>Network name>Forget this network?  Find the network again, tap on it, enter the password?
    Settings>General>Reset>ResetNetwork Settings? Find your network again, tap on it, enter the password?
    Restart the iPad? Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

  • Iphone 3G suddely won't connect to any wifi network

    Hello, my IPHONE 3G suddenly stopped connecting to my home wifi; before i have no problem. Lately it stopped connecting but after turning it off/on it works again. Now, a few hours after updating to 2.2.1, it can't connect to wifi anymore, I was surfing then it disconnected. I tried everything, reset, factory default and even resetting my home wifi router but no success. Interestingly, other 2 ipod touch and 3 laptops have no prob with my home wifi. Please help...

    Thanks for your reply.
    Yes, i believe it is already a hardware problem because I tried everything. And yes, I cannot connect anymore to other networks which i usually get connected. Although my iphone can see those wifi networks but can't connect anymore.
    My prob is my iphone is ordered from a store in the philippines and that store bought it in Hong Kong, this is an open line Iphone 3G. I checked the warranty online and it says up to Oct. 30 this year. I hope they will fix this at Vancouver Apple Store. I have an appointment to the geniuses there today.

    It could be a HW problem, but does it get many black bars in the Airport icon?
