App-Manager does not connect to the Simulator OS Firefox on Windows 7

OS: Windows 7

Firefox: 28

6.0pre8.20140112 Simulator 1.2 Firefox OS

When I run the simulator it opens fine and I see a Firefox OS Desktop
But the App Manager does not connect. The console at the bottom right says:

.. localhost:56455 options (the port varies)

.. connection timeout. Possible causes: has not clicked 'accept' (guest).

.. .disconnecting

.. .disconnected

I have disabled my firewall, restarted firefox and even system - did not help
There is a similar bug - but I don't know if we are talking about the same thing:
https://support.Mozilla.org/en-us/questions/988385

Thank you

Well - I already knew these links and I can't find anything useful
Anyway, I tried the Simulator instead of 1.2 1.3 (unstable)
This one works very well

  • Start the virtual machine and wait for WF, does not connect to the computer virtual for Vds (Windows 2008 R2)

    Hello

    See a strange problem with only a Windows 2008 R2 model. When you use the built-in function "Start VM and wait" workflow to start a virtual machine (after conversion from a template either manually, or through workflow) NIC of the virtual machine (I tried VMXNET3 and e1000 times) does not connect to the problem. Vds can be replicated in a different VCenter, so spreading the vds. I also created several models of Windows 2008 r2 and all have this problem.

    If the model is converted and started outside VRO, it gets an IP from and is connected to the VDS immediately

    Tried add/remove the NIC of the model

    Tried to move the comments on different hosts

    Tried to create a new template from scratch

    NOTE: Windows 2012 R2 doesn't have this problem in the same circles, the only constant is the Windows 2008 R2 being started by VRO.

    Anyone seen this before?

  • Satellite L350 does not connect to the internet, network adapter yellow exclamation

    Trying to help my Nan with his laptop...
    Model is Satellite L350-170

    Does not connect to internet, even using the Ethernet cable. Network cards have yellow exclamation marks on it and seems he needs an updated driver. How the hell can I download and update if it does not connect to the internet. And then, what update is necessary, because I searched on here and there is no update driver for network card?

    She had various internet help from its supplier and a visit at home but still no joy. Internet works fine on other devices. Any advice greatly appreciated.

    All the drivers can be downloaded from the Toshiba UE driver page.
    http://www.Toshiba.EU/innovation/download_drivers_bios.jsp
    Choose your model of laptop in the form of download and the system that is pre-installed on you unit.
    Then, you will get the list of drivers.

    If you are not able to connect to the internet due to lack of driver LAN/WLan, then you another computer for download.

    You asked how to remove the network card?
    Usually, you need to access the Device Manager (in Control Panel) then we need to expand the area to network adapters and you will find the LAN and WLan card.
    Click the single LED adapter, and then press or click on uninstall button driver

  • Pavilion G6 does not connect to the cellular device

    I have a Pavilion G6 with Windows 7 OS, which is used as a mobile data terminal. I am trying to use my iPhone Verizon 5 c to connect to a hotspot. All my other HP laptops connect to this phone without problem, but the G6 does not connect to the internet via the phone with cable, wifi or bluetooth. The G6 recognizes the phone and shows it in "unspecified devices." I tried everything to get it to connect without success.

    Hey RC800,.

    Thanks for the info.

    I forgot to ask before, can you tell me the exact model specifications what do you use? For more information on the search for your model and product numbers, click here: How can I find my model number or product number?

    If the laptop connects to other devices, we can say that the material is very good. If he does not see the iPhone theres only a few things you can try. The adapter in your laptop is probably 802.11 g capable which is the minimum requirement for the hotspot iPhone, so we can exclude.

    Please, try the following:

    Turn off the power to the adapter:
    1. open Device Manager. (Win Key + R > type devmgmt.msc > OK)
    2. expand the network adapters.
    3. right click on the Ethernet adapter / wireless, and then click Properties.
    4. click on the power management tab.
    5 remove the check mark next to allow the computer to turn off this device to save power.
    6. click on OK.
    7 test cycle.

    Reset the TCP/IP settings on your PC:
    1. go to your start screen/menu and type CMD.
    2. right-click on the command prompt icon and select run as administrator.
    3. in the window that opens type "netsh int ip reset resetlog.txt" without the quotes and press ENTER.
    4 restart your PC and test.

    It can also help to reset the winsock catalog:
    1. go to your start screen/menu and type CMD.
    2. right-click on the command prompt icon and select run as administrator.
    3. in the window that opens type "netsh winsock reset" without the quotes, and then press ENTER.
    4 restart your PC and test.

    Reinstall the NIC drivers:
    1. download the drivers from here , but do not run them again.
    2. go to your Start menu/screen and type Device Manager.
    3. expand network adapters.
    4. right click on the wireless adapter and choose uninstall.
    5 install the drivers downloaded in step 1.
    6. restart your PC and test.

    Test another iPhone connection:
    Explicit. This will tell us if it's only an incompatibility with a phone or any iPhone hotspot. Try a hotspot Android will help narrow things down as well.

    Let me know if this helps.

    I have a Compaq Presario CQ61-410US (WA974UA) which is equipped with an Atheros AR9285 B/G/N wireless network adapter.   The laptop Internet access was fast and stable when using a Wi - Fi N.   Its pilot AR9285 was the initial version of the 8.0.0.172 factory.  But because there were so many subsequent driver updates, I've updated the display driver version from the support page 8.9.9.316 (sp48755.exe).  However, after updating the driver, I immediately lost Internet access.   The laptop is running Windows 7 Home Premium with Service Pack 1 and 64-bit.

    Hello:

    I'm glad that you were able to restore your internet connection.

    I'd go with the latest driver HP vice one from another source.

    The only time wherever I go outside HP for wireless network drivers is if you have an Intel wireless card.

    My recommendation is to use the free MS Security Essentials antivirus/antispyware, which never interfere with how "things important works" on your PC, such as network connections.

    http://www.Microsoft.com/en-US/Download/details.aspx?ID=5201

    Your router with a hardware firewall and a software firewall Windows. I don't see the importance of adding other firewalls.

    Unless you have a lot of albums secret info on your PC that pirates would like to get my hands on, these fully functional security roadblocks are adequate for most of us.

  • Laptop does not connect to the internet, office. Both use the same router. Tried troubleshooting, does not. Help!

    I have a desktop computer and a laptop. Both use the same router. The laptop does not connect to the network, but the office has no problem. My wireless adapter on the laptop is on, I tried troubleshooting. I tried to turn it off for 30 seconds then restart him. But nothing is resolved the problem. Any ideas would be helpful! Thank you

    Hello

    Maybe this can help.

    These steps and tell us where is the breaking point.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

    ----------------

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

    If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

    ---------------------------

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

    Above everything is OK, you must be able to connect to the router.

    Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

    If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

    Enable security wireless after you eat to make a functional connection.

  • Does not connect with the e-mail server after update.

    Thunderbird ran an auto update yesterday. Then it just stopped working. It does not connect with the Comcast email server. An error message appears "Unable to connect" and "the connection was refused when attempting to contact live.mozilla.messaging.com. I don't want to uninstall and reinstall for fear of losing my emails and address book. How can we get Thunderbird set, there is no tool in the toolbar to enable the debugging and correction of program errors.

    I use Thunderbird version 38.1.0.

    Thank you.

    The problem solved itself, Thunderbird has just started working. I followed the thread suggested by Christ1 and found none of it applied. No malware, no browser, no certificate error security block. I did, however, in Thunderbird, under Tools/Options/General uncheck the button for "When Thunderbird launches, show the Start Page in the message box." I do know that if this helped, Thunderbird still do not access Comcast mail for hours after that, even with several stops and restarts.

    Until the next problem...
