Network Monitor does not not on a whim

I use Network Monitor to months and suddenly that it stops working today, the tab is still there and I checked devtools.netmonitor.enabled and the value is always true. The problem is the button to launch performance analysis does not respond to clicks, in fact even the filters on the bottom (HTML, CSS, HS, XHR) are not working as (by clicking on them normally should at least highlight in blue but now its totally insensitive to the user clicks)

I would appreciate any help from you guys. Thank you.

UPDATE: I solved the problem by resetting all values related to netmonitor and the problem goes away. I don't know why, the values are mixed however. That's why I'm scoring this issue as resolved, sorry for wasting space forum.

  • WUSB54GC - WLAN monitor does not not on Windows 2000 SP4 computer laptop

    I have a WUSB54GC v3 and I tried to install the drivers and the WIFI monitor on a Gateway Solo 5300 laptop running Windows 2000 SP4.  When I put the disc, the installation automatically started, but stopped after a few seconds with a pop message saying, "this version of windows is not supported" (or something similar to that).  I read in this forum and learned how to manually install the driver from the disk I did.  I checked the device using troubleshooting in Device Manager and shows the driver to be installed correctly and the device works correctly.

    My big problem is that the monitor WLAN (the little green square in the bottom right of the screen) will not illuminate.  There are no available wireless networks and the monitor does not respond to the "Refresh" or anything else.  It seems to be "dead".  How can I get the monitor to work?

    Thank you!

    WUSB54GC is not compatible with Window2000... So either you can upgrade your operating system to Windows XP, or you can go for different cards as WUSB54G.

  • Monitor does not work after installing Windows 7.

    I have a Dell laptop with a Dell S1709W Flat Panel screen.  After replacing the Windows Vista came with the laptop for Windows 7, the monitor does not work.  The monitor said that he does not any signal from the computer.  The computer does not show that it has detected the monitor.  The monitor's cable and the connections are good.  What should I do to get the monitor to work?

    You have a graphic external connector for a secondary monitor, if yes attach it and then go to the Dell support web site and download Windows 7 drivers for your laptop model. Install the driver chipset first, then the driver graphics/video, network/LAN and drivers of the potential.

    If you do not have an external graphics connector, call Dell Tech support. They have a method to recover your system without losing data or applications.

  • Firefox has only display problems in the upper left region of only my Dell U3011 monitor; the monitor does not have these problems with any other application

    Some parts of the Firefox window are translucent, allowing the image of the desktop to show through. These regions are anything but great internet site central image which behaves normally. Unless the desktop is completely black this problem makes reading the tabs, address bar and the bookmark are difficult if not impossible. I encounter this problem only on my new Dell U3011 monitor. Firefox is the only application that has this issue on the Dell monitor. The monitor built into the laptop that animates the Dell monitor does not exhibit this problem. The laptop is a Lenovo W540 running Windows 7 64-bit. Thank you very much for your help. Steve Schupbach

  • HP monitor does not display "DVi signal.

    My HP LP2275w monitor does not display "DVI signal" when connected with a DVI cable (supplied), but when it is connected via a VGA cable and adapter DVI/VGA (both supplied) it works but no BIOS screen. It begins immediately with the logo of the VICTORY.

    I just bought new HP Pavilion 500-158eg, Intel Core i5-4440, with AMD Radeon HD8570, 2GB processor, running on WIN7 Pro 64 b. VGA and another port of the motherboard are initially blocked so I can connect the monitor only via the output HDMI or DVI on the graphics card.

    I should note that on my old machine without a name with the graphic upgrade ATI Radeon, there is no problem and I used the same cable. There was an electric shock that causes the collapse of the motherboard so I can't even re - check on the old machine. I can't verify if there is a problem with the DVI cable because all laptops in our housing have only the VGA output...

    All solutions?

  • Wireless network adapter does not work on my Satellite A200

    What can I do?

    BIOS bug? I don t think so

    First of all, you must make sure that this isn't a hardware problem. In this case, insert the Toshiba Recovery CD and reinstall the operating system of this device. This will outline the laptop to factory settings. Notes; This would format the whole HARD drive.

    After the new installation, you must activate the WLan switch on the side of books, and you can then use the switch button FN + F8 to select the WiFi network.

    I assume that you have already configured your Wlan router. So the same settings such as the SSID, encryption of WLan, etc. must be defined on the laptop too.

  • Primary monitor does not work after last nights updated

    • I'm running Ultimate.
    • I have two monitors.
    • My primary monitor does not work.
    • I checked the VGA cables. This isn't the issue.
    • Edit: Just realized that my main monitor is a monitor "Westinghouse". -Who is a "Plug-in-and-play" monitor, there are no drivers.
    • Reinstalled the ATI drivers, did nothing.
    • SYSTEM RESTORED, still nothing.

    I ran the most recent update for final last night, then fell asleep. Everything worked before that date, but when I went to turn on my computer this morning, only my HP [my second monitor.] w17e worked. He said he was installing updates from last night, so I had no problem with him and thought it might show something once like this on the login screen.

    Once that has happened to the login screen, it showed it for a fraction of a second before disappearing. I entered my password and it connected as usual. After login, I turned off my monitor, and then back on, and it showed my normal desktop for a moment, [enough for me to close two-three programs] before she returned empty.

    Hello
     
    I recommend you to update the graphics drivers and see if it makes a difference. You must be logged on as administrator to perform these steps.
     
    1. open Device Manager by clicking the Start button, click on the Control Panel, clicking system and Maintenance, and then clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. in Device Manager, locate the graphics card and then double-click the device name.
    3. click Driver tab, then click on set to update driver and follow the instructions.

  • I need help, its frustrating me! network discovery does not illuminate.

    my network discovery does not illuminate. Whenever I try to turn it on I get an error message that says: (the specified service does not exsist as an installed service)! I need to elp, its frustrating me! I have windows vista.

    Hello

    Did you change your computer?

    Method 1:

    Based on the network location you choose, Windows affects a State of network for network discovery and opens the Windows Firewall ports suitable for this State.

    Step 1: We recommend you to check if the elements of network discovery are enabled in Windows Firewall. To do this, try the following steps.
    1. click on start, type firewall and then click Windows Firewall with advanced security.
    2. click on rules of incoming traffic in the left pane and select the (SSDP-In) network discovery and network discovery (UPnP) - in the list.
    3. click on rules of outgoing traffic in the left pane and enable network discovery (SSDP-out) and the discovery of the network (UPnP-Out) in the list.
    4. apply the changes and check the result.

    For more information about network discovery, see this link:
    http://Windows.Microsoft.com/en-us/Windows-Vista/what-is-network-discovery

    Step 2: Check the status of the following services: browser, TCP/IP NetBios support.
    1. Click Start, type services.msc and press to enter.
    2. from the list of services, double-click the service computer browser and TCP/IP NetBios support.
    3. change the startup type to automatic and start the service.
    4. apply the changes.

    Method 2:

    Now we go ahead and try to enable the discovery of the network on your computer and check for the issue.

    Network discovery is disabled by default for public networks. Changing a network location type to home or work is the best way to turn on network discovery. To learn how to change a network location type, see Choosing a network location. To enable discovery manually, follow the steps below.

    To turn on network discovery

    1. open the network and sharing Center by clicking the Start button, clicking Control Panel, clicking Network and Internet, and then click Network and sharing Center.

    2. If network discovery is off, click the arrow button expand the section, click turn on network discovery, and then click on apply. Need administrator permission if you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    I also suggest you turn on discovery of the network link and check.

    Enable or disable network discovery
