Windows 7 enterprise - wireless network does not work at the office

I'm a remote worker for a company.  I travel offices across the United States and hit this problem before, but thought it was just a transitory problem.  However, now I am in our headquarters and the problem has resurfaced.  Essentially, networks under Windows 7 Enterprise associates for wireless access points but cannot obtain a DHCP address.  I tried the usual: enough and ipconfig ipconfig / renew, I took it to our support people who confirmed that the configuration is correct, we have tried uninstalling the driver and put back in place, all in vain.  The configuration of the machine is:


Dell Latitude E6400

Windows 7 Enterprise x 64

Wireless: Intel 5300 AGN

Driver:

Vendor: Intel

Version: 12.4.1.4

Digital signer: Microsoft

Path: C:\Windows\system32\DRIVERS\netw5v64.sys

The wireless works now in my office at home (I have a Windows 2003, Cisco 1200 AP domain and use WPA2 with PEAP to authenticate).  Please note that the configuration has NOT changed since the last time I was in this office (about 3 weeks ago).  We are a Windows 2008 R2 using NPS area (AFAIK).  Help desk support people are completely baffled.  The good news is that the cable works fine.

I have included the following diagnostic report (with the suppressed SSID):

  • my wireless keyboard does not work on the letter and number keys.

    It seems to be connected to the computer, because it does not work on the control button and snooze sound

    Hello

    -Have you made any recent hardware / software changes prior to this question?

    -What is the brand and model of wireless keyboard?

    Method 1: run the hardware troubleshooter.

    Open the hardware and devices Troubleshooter
    http://Windows.Microsoft.com/en-us/Windows7/open-the-hardware-and-devices-Troubleshooter

    Method 2: update a hardware driver that is not working properly

    (a) open Manager devices by clicking the Start button, click Control Panel, click System and security, and then, under system, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    (b) in the list of hardware categories, find the device you want to update, and then double-click the device name.
    (c) click on the driver tab, click Update driver, and then follow the instructions. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

    Method 3: resynchronize your device with the receiver

    To resynchronize the mouse or the keyboard with the receiver, follow these steps.

    Note When you synchronize the mouse or the keyboard le clavier with the receiver, place the device near the receiver and store other keyboards and wireless mouse at least 6 feet.
    1. press the button on the receiver and check that the light on the receiver starts flashing.
    Note Some newer devices from Microsoft are subject to their receiver and cannot be reset. If your device has a button, go to method 2.
    2. If a dialog box appears on the screen in seconds, follow the instructions that appear on the screen. Otherwise, continue to the next step.
    3. press and release the Connect Channel button on the bottom of the mouse or the keyboard.
    4. check the green light on the receiver. A continuous green light means that the synchronization was successful. If the problem persists, repeat steps 1 to 4.
    5. for the Wireless Notebook Mouse: this issue can occur if the micro-switch on the bottom of the mouse is not released. Use a PIN or pen to try to release the button, if it is pressed.

    Hope this information helps.

  • Wireless camera does not work with the new router

    Hello, I'm having a problem with a camera D-Link DCS932L after you set up the EA4500.  The manual of the camera can be found here.

    http://d2okd4tdjucp2n.CloudFront.NET/DCs-932L_A1_Manual_v1.00 (NA) - en.PDF

    It worked fine with my old D-Link router.  The rest of the House has not had a problem with the EA4500.  There is a level of criticality around this camera certail and if I can't make it work, I'll have to return the router.  Configure the redirection of port as 5556 ~ 5559, TCP protocol (but I tried "Both" as well"with the IP address of the camera.  It still does not work.

    I craft but not in networks, i.e. I'm not stupid with tech but port quarrels is out of my comfort zone.  This camera with our old router setup took minutes.  I spent five hours trying to make it work on the EA4500.

    I guess you have the static IP value, or having a reserve of DHCP MAC address for the camera, network OK settings.

    What was the authentication wireless on the old router and that you use the new 4200?

    Is it possible that the camera does not support the encryption used by the 4200, i.e. wpa2-personal?

    Have you tried WEP to see if the unit works then?

    Hi mate,

    Theoretically, network controller can mean both WLAN or LAN card.

    Anyway, if you need driver WLAN, you can visit the Toshiba WLAN portal. There, you can always get the latest WLAN drivers:

    Hello

    Satellite A100-549 PSAA4E was delivered with Atheros 11 b/g wireless network card.
    In this case the Atheros WLan client utility should be preinstalled on this OS.
    I advise to use this tool to configure WLan settings.

    In addition the wireless network card has been configured and set WLan channel 11. Please check if your router has been also on channel 11!

    I assume you are using the image of preinstalled Toshiba.
    This image contains the right WLan driver and usually the new installation is not necessary but if you are lloking for the new WLan driver I would recommend take a look here on this Toshiba WLan Center Portal:

  • I just bought the wireless desktop 800 Windows keyboard and mouse it does not work on the Windows XP desktop

    I just bought the wireless desktop 800 Windows keyboard and mouse. It works fine on my Win7 laptop but not on my XP desktop even if it says it is compatible with XP. Any advice?

    Hello

     

    Thanks to join Microsoft Community where you will find all necessary information about the Windows operating systems.

    You cannot use the Wireless Desktop 800 keyboard and mouse.

    The problem may occur if the devices are not detected.

    What exactly happens when you try to use the devices?

    A fixit could be used if the devices are not detected.

    See the site:

    Hardware devices do not work or are not detected in Windows

    I hope this helps. If the problem persists, or if you have problems of Windows in the future, let us know and we would be happy to help you.

  • Wireless network does not work when I put a password

    Well actually, I use a wireless network at home, and when I try to put a password, it won't let me connect to the internet, but my xbox connect when there is a password there and other laptops don't. When I try to connect by using a non-secure network it connects to the internet, but on any other laptop but mine it asks me to set up the connection, while on my laptop, it goes straight to a connection.

    If you guys can offer me a solution to this problem, I would be very grateful

    Hi Sh4dow,

    You can check out the following link and check if it helps:

    View your preferred wireless networks

    http://Windows.Microsoft.com/en-us/Windows-Vista/view-your-preferred-wireless-networks

    You can also temporarily disable the security software and firewall installed on the system and check if the problem persists. If this resolves the problem, then you may need to update or change the settings of the security software.

    Note: Be sure to enable the security software on the computer after checking.

    Hope this information is useful.
