  • Cannot view or connect to the Wifi network of 5 GHz with Time Capsule from Apple 5th generation

    I have a new Apple Time Capsule 2 TB with 802.11ac network support. I have setup my base station in order to disseminate the 2.4 GHz and 5 GHz network SSID. I have 2 apple (iPad Mini and Macbook Pro) time devices can see and connect to Terminal 5 GHz network however I have also a Lenovo Vibe P1 phone (dual band wifi supported) and Samsung Galaxy Tab S compressed (dual band wifi supported) and these devices cannot see or connect to the network of 5 GHz of Base Station. I also have a Cisco router that has a dual-band support and all my devices can see and connect to the network of 5 GHz of this router.  So I wonder why I have this problem with time capsule?

    I have reset my base twice station and it is a new device purchased last month.

    Any help or suggestion is appreciated.

    Did you use the SMB compatible names for everything...?

    That is to say the alphanumeric short, without spaces and Pure...

    for example base station name... TCgen5

    name TCwifi wireless

    Have you also used the password corresponding to these requirements... but can be between 8 and 20 characters.

    If so, then you must give a different name to 5 GHz and delete the password and test... If it's not yet connect the test manually on channels 36, 44, and 149 for example if you are in the USA...

    Wireless router / Internet problems

    I am running Windows Vista Home Edition with Security Essentials.  I can connect to my wireless router, but cannot get internet connectivity via Wireless.  If I connect the cable to the port on the router, I get internet connectivity.  Is there a firewall setting that could cause this problem?

    Hello

    Your router could be suspicious here, you have successfully updated its firmware as a possible solution? And I would like to
    Update your WiFi drivers on computers. How you are positioned in the router? Are there
    obstacles in the path?

    Actually try updating your driver and disabling the network logon.

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager
    http://www.Vistax64.com/tutorials/193584-Device-Manager-install-driver.html

    Download - SAVE - go where you put it - right click – RUN AS ADMIN.

    You can download several at once however restart after the installation of each of them.

    After watching the system manufacturer, you can check the manufacturer of the device an even newer version. (The
    manufacturer of system become your backup policies).

    Repeat for network (NIC) card and is a good time to get the other updated drivers as Vista like
    updated drivers.

    I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they
    are almost always old, and you can search drivers manually as needed.

    Make sure you know the details of connection to your wireless router - SSID and password.

    You lose connection when you do and have to redo your logon.

    Control Panel - Network & Sharing Center - right, click Customize - page set of network locations.
    lower left click on merge or delete network locations - REMOVE all instances of your network (and the
    others you don't use anymore) - REBOOT. Start - Connect To log on to the network.

    I have a HP G60-214EM laptop and cannot get it connected to my samsung 26 "smart tv. Can anyone help?

    Hello Maureen56,

    I understand that you want to connect your TV to your laptop.

    To connect your computer to your TV HDTV using an HDMI cable, follow these steps:

    1. Locate the HDMI port on the back of your TV. It should be more than one, in order to choose the one that is otherwise unused. Note the port on which you choose.
  • Email - connection closed gracefully

    Having just opened an Outlook account a week due to problems with another provider, I start to wonder if I made a sensible thing. I look at my emails via an email client.

    Friday I sent a lot of mails from outlook and everything worked fine. Today, having changed anything I can no longer send emails even though I can get them. (I can send via gmail).

    [ERROR] - an error has occurred. Account: ' pop - mail.outlook.com ', Protocol: "SMTP", task: SMTP send all messages, Server: ' smtp - mail.outlook.com ", Port: 587, TLS: no (1.0), error code: 0, error message: 'connection closed gracefully.", the last response from the server: "" for more details look in the "Log" tab - error messages are marked in red.

    This problem was solved when about 30 minutes after I posted the question and one hour after the problem began, I received an email from saying that, if I wanted to send Outlook messages, I needed to check my account by copying the number of letters at the end of the email. I did and it worked since!

  • BlackBerry cannot accept the connection via the Mobile network?

    Hi all, on Blackberry, I want to open a server socket to listen to a connection come from other devices.

    Here is my code:

    String url = "socket://:12345;deviceside=true";
    ServerSocketConnection scn = (ServerSocketConnection) Connector.open(url);
    SocketConnection sc = (SocketConnection) scn.acceptAndOpen();
    

    Mobile network on that BB is ok, but it cannot accept any connection.

    I also use its mobile phone network to connect to other servers, it works fine when it's the client socket.

    I tried with the Wifi network, and it works very well.

    String url = "socket://:12345;interface=wifi";
    ServerSocketConnection scn = (ServerSocketConnection) Connector.open(url);
    SocketConnection sc = (SocketConnection) scn.acceptAndOpen();
    

    In my view, Network Service Mobile prevented so that other devices connect to it, is it true?

    Please explain it to me, thank you very much!

    This approach only works for mobile connections, when the data are pushed to the device.  You cannot use it to connect to other phones directly.  Sorry

    Just, I solved the problem I had.

    SQL Web browser has not been activated.  solution: in properties SQL server configuration manager, transformed the startup to automatic mode and activated the service.

    Microsoft Visual Studio project property targetdatasourcefolder had a server name that precedes the name of the folder. Removed the name of the server.  This works.
