The wi-fi network "" could not be joined

This is the third time I have this problem. The two first times it have resolved itself and I have no idea how. It started working again just as suddenly and unprovoked as it stopped. But this is a serious threat to my work situation and I can't find a good answer to it. It stopped working again this morning and haven't worked since. I've restarted the comptuer a few times and renewed the DHCP lease (whatever that means). I have a macbook retina, bought in May of this year. There's been no problem connecting to my Zyxel router for 5 months, and now suddenly this. One place suggested that some SMC thing have to be reset in my computer. What does that mean, how is it done and is it a good idea? Will it help? Does anyone have any idea what's going on with this?
A

Try a SMC reset. The article covers when this is required, but doing this will not affect anything.

  • I have just returned from visiting Italy where I got the internet from various wi fi addresses. Now on my return to England my wi fi will not connect to my router (smart phone does connect OK)saying 'this wi fi network could not be joined'. Any ideas?

    The Air Port fan icon on the menu bar is greyed out and when I click it to connect a message  appears ' the wi fi network could not be joined '. The wi fi is turned on both on the router and selected as on in the screen drop down. The smart phone works perfectly with the wi fi router so it must be something to do with the Mac book. It worked fine before I took it to Italy. It does work Ok using an Ethernet cable. Could it be that some Italian IP's are being stored in the laptop and the UK IP is not being recognised? Any ideas on what could be done? Any advice would be appreciated. Thanks !

  • 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?

  • When I replaced my PC desktop with a Mac Mini and hooked up my HP printer to it, I discovered my other computers on the Wi-Fi network could no longer access the printer.  The manual says Maverick OS will not allow PC's to access the printer. Any thoughts?

    When I replaced my PC desktop with a Mac Mini and hooked up my HP printer to it, I discovered that my other computers on the Wi-Fi network could no longer access the printer.  The manual says Maverick OS will not allow PC's to share the printer. Does anyone else have this problem?  My printer does not have on-board Wi-Fi but, otherwise, works fine.  I shouldn't have to buy a new one.  Is there a OS patch out there that would open the printer port for my PC computers?

    I'm assuming that on the Mac, the System Preferences -> Sharing -> Printer Sharing -> [X] HP printer -> Everyone can print is selected?  That is to say, the Mac will allow anyone to print using the printer, and that you did not try to restrict who can print.
    How is your network configured?  Bonjour as a protocol will NOT cross a router boundary.  If you have 2 or more subnets active with the PCs on one subnet and the Mac on another, that would block the PCs from seeing the Mac.
    You could have multiple subnets if you have more than one router, such as an ISP provided broadband modem/router and another WiFi Router.  If the PCs are talking to one router and the Mac is talking to another, that could be a 2 subnet situation.  The additional routers must be put into bridge mode, which is done differently depending on the router.  But the basics are to diable DHCP and NAT services on the secondary router(s) having just one active router on the network.
    Also, using Bonjour Browser on my Mac, it is showing me that the printer is being advertised as using Internet Printing Protocol, so if that is something selectable on Windows, maybe you can bypass Bonjour on Windows.

  • Receiving "The product distribution file could not be verified. It may be damaged or was not signed" at my home network. But not at my office network

    Hi,
    I've recently updated my late 2009 macbook from Snow Leopard to Mountain Lion. Things were working good. Yesterday I updated in to 10.8.4. Today I saw an update for Xcode. I tried installing it. But I have been constantly receiving "The product distribution file could not be verified. It may be damaged or was not signed" in App Store. There after I am not able to purchase anything from App Store. I tried following things:
    1. Tried downloading the updates in Safe Mode. ==> No success.
    2. I deleted folder present in /var/folders ==> No success.
    3. I changed my network by converting my phone to WiFi hotspot and I stopped receiving the error.
    Can somebody please suggest any reason/solution?
    Router I am using is D-Link N300.
    Thanks.

    The problem got solved by changing DNS to public DNS from Google. i.e. 8.8.8.8 and 8.8.4.4.
    Thanks

    If you are using someone else's WiFi they may have restrictions in place.

  • Hotspot login cannot open the page because it could not establish a secure connection to the server.

    I am trying to connect to a public wifi network.  My iPad connects marvoulesly.  My iPhone not so much.  I have an iPhone 4 and everytime I go to connect, it goes to a pop up page where I'm supposed to click a link to adhere to their TOS.  When I get the pop up page I get "Hotspot login cannot open the page because it could not establish a secure connection to the server"
    I've reset the network settings and nothing changed.  Same error message.  Any tips or tricks to fix this?  I'm laid up on bed rest in the hospital and would really rather that I not use all my data minutes...
    Thanks!

    Updated to iOS6 on an iPhone 4 this morning, and now when I attempt to connect to my work wireless, it connects for a moment then attempts to popup some login page (I sometimes get the hotspot login error you've mentioned) and because the page doesn't exist I can't get connected to the wireless netowrk.
    What the heck have apple broken in this update?
    Why when joining a normal wireless network is my phone even going near a Login page? What is this and how do I disable it?
    Oh, and I'm posting here because your suggestions of disabling the Wi-Fi and Cellular data netowkrs doesn't solve the problem.
    [Edit: seems while typing this leaving the cellular data disabled, it's now letting my join wireless - seems to be some timeout on it fixing the issue - I'd still like to know what this login page is it's attempting to locate is for.]

    Same problem. I can see the itunes store so not a problem with windows firewall. The account is active on my iphone so i know i am not locked out. I can connect the PC to my iphone so i know itunes is working ok. It is just logging into itunes on this pc which doesn't work. Only thing I can think of is that the email address I use for my apple id has been offline for a while and is working again now, I'm wondering whether this has been the case for others who are having this issue?

  • What's the reason for this message, "A server with the specified host name could not be found" ? I'm using iPhone 4s, 16gB, iOS 7.0.4

    I get a pop-up message saying "A server with the specified host name could not be found", whenever I try to access any streaming websites/apps or even WhatApp over Wi-Fi and I cannot access the specific THING for that moment, and I've tried switching Wi-Fi On and Off both in my Phone and also in the Router. I got an internet connection and a Wi-Fi router just before two days, and it's happening since. I got the internet speed around 80kbps and i can easily stream YouTube videos except sometimes, I receive that annoying message. I can't even browse the internet in Safari, which says "No Internet Connection"(Even though the Wi-Fi is connected), and I can access it after somewhile (say 10 minutes, it'll be perfectly alright). I use iPhone 4s. And everything about the internet connection is totally fine in my Computer, but not in my iPhone, as I've explained the issues, above. If there are any technical settings that I should change/modify, either on my computer(Windows 7 OS) or in my iPhone(iOS 7.0.4), PLEASE let me know
    I hope I've provided enough information for the reader to understand my point. (I apologize for my verbal mistakes, if there are )
    THANKS

    Hello Paneesh,
    Thank you for the details of the issue you are experiencing with Wi-Fi on your iPhone 4s.  I recommend the following steps:
    Be sure you're in range of your Wi-Fi router (access point).
    Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your W-Fi setting is dimmed, follow these steps.
    Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
    Restart your iOS device.
    Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
    Tap and Forget this Network.
    Try to connect to your desired Wi-Fi network.
    Note: You may need to enter your Wi-Fi password again if your network requires one.
    Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
    Update your device to the latest version of software.
    Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
    If the issue is still unresolved Wi-Fi disconnects or signal strength is less than expected
    Move closer to the Wi-Fi router (access point).
    Check for sources of potential interference.
    Remove any case, stand, or other accessories from your iOS device and see if signal strength improves.
    Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including
    previously connected Wi-Fi networks and passwords
    recently used Bluetooth accessories
    VPN and APN settings

  • The itunes update server could not be contacted. Ran diagnostic and followed many support reccomendations with on success.

    For at least the last 36 hours I have been unable to download updates from the itunes server for either itunes itself, or for iOS for my iphone (I need this since I am locked out of my phone). I was able to get around the problem of not being able to update itunes from the itunes server by downloading 11.0.4.4 from apple.com instead, but I don't believe I can do this for the latest iOS.
    I have tried troublshooting from the support instructions for hours with no luck. Itunes is the only program that is having internet connectivity issues. I have tried disabling windows firewall, completely uninstalling my antivirus, and logging in/running itunes as an administrator. I have purged my hosts file and made sure that LAN settings are set to auto-detect. I have rebooted my router. There are no third party programs running that filter internet connections.
    What else can I try?

    I have completed the Advanced iTunes Store Troublshooting workthrough and my problem persists.
    For reference I will detail the steps I have followed from the Advanced Support link iOS *08* provided above.
    Isolate the issue:
    1) the problem is with iTunes (I can connect to other secure websites, including the apple webpage + login).
    2) verified the problem is not with the network (other devices on my network can connect and download iTunes updates).
    3) I cannot resolve the problem by connecting to another network.
    4) I have created inbound and outbound rules to allow all traffic to/from ports 80, 443, 3689, 5297,  5298, 5353, 8000-8999, and 42000-42999. I have allowed these ports full access to all network types and all programs. I have also made sure that all apple products, especially itunes, are allowed in the list of windows firewall exceptions.
    5) My date, time, and timezone are correct.
    6) I am using iTunes as an administrator. I have posted the results of the diagnostic network tests above in my Original Post.
    Blocked by software Firewall:
    I have allowed an exception in the firewall for itunes and bonjour.

    "If there's no firewall preventing access, but the iTunes Store still does not work while other Internet services (websites) work, the iTunes Store may be blocked by your configuration."
    Blocked By Configuration:
    I have run iTunes Diagnostics (results above) and the "Secure link to iTunes Store" section did not pass
    I opened IE, made sure I am "Never dialing a connection"
    My LAN settings are set to "Automatically detect settings"
    I do not have any proxy settings
    I have unchecked "Check for server cerificate revocation*" under Advanced IE properties
    I have enabled "Use SSL 3.0" and "Use TLS 1.0"
    I saved and restarted. Still no joy.
    Rebuild Network Information
    I flushed the DNS Resolver Cache
    As mentioned above I reset the host file to default, and also tried to alternate method outlined in the support document involving creatings a "Copy of hosts" file and moving, editing, and returning the file to drivers/etc.
    I then restarted.
    Please Help! This is getting rediculous!

  • Federated free busy information - the recipients mailbox server could not be contacted

    Hi guys, really hoping someone can help with a free busy issue I'm having.  
    I've configured a new forest with exchange 2013 installed in preparation for moving all AD objects to the newly created forest to resolve a single label domain issue.  The source forest has exchange 2010 SP2 installed.  I've setup a trust between
    the forests and dns is resolving okay.  Federation has been setup for each of the forests and sharing configured but free busy info isn't available.  When trying to retrieve FB from the new exchange 2013 mailboxes i get "the recipients mailbox
    server could not be contacted"  Trying to lookup FB from new forest to source "the recipients server could not be contacted"  I've followed the troubleshooting steps in the following link: http://johanveldhuis.nl/en/troubleshooting-federared-sharing/
    which are all okay except when I run Test-FederationTrust -UserIdentity [email protected]  On the exchange 2013 forest all tests are successful, on the exchange 2010 forest all tests are successful with the exception of token request which
    returns: failed to request validation token.  Any help on this really appreciated 

    Just check the application log again and found this:
