• Wireless connects, but internet does not work

  My wifi signal is strong. My computer says that it is connected. Diagnosis shows the signal is stable, but when I open a browser, it does not connect.

  I tried the Ethernet connection, but it's the same story. Computer indicates recognition signal, but it will never truly connect. It will connect in Safe Mode, however.

• wireless connected but internet does not work

  Since yesterday my laptop has had problems connecting to the internet. It will say that it is connected to the internet but yet when I open a browser or any other program requiring internet, it does not work. However, when I use the same connection from another laptop, the internet works.

  I tried to use the option diagnose & repair and he always tells me that everything is fine. I also tried to restart my laptop and check my firewall settings, which did not help either. any help would be greatly appreciated!

  Hello

  Turn off the router or the modem (unplug the power supply) - wait 3 minutes, then the power restore - restart the computer.

  If necessary:

  Two methods - I would try 1. first and use 2. only if necessary because with 2 it can come back.

  1.

  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. If you usually use WiFi try a wire
  and if you usually use a wire try WiFi. Update, one being not used 1.

  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 card (NIC) network 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 router wireless and wired - 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.

• Follow this procedure when the Sansa Connect recovery tool does not work!

  Hey people;

  This thread is just to consolidate the info from a lot a longer wire, earlier.

  Currently, the Sansa Connect recovery tool may or may not work for you.  You can see an error like 'failed to connect to the Internet' or "cannot retrieve the device, SanDisk contact technical support for assistance."  If Yes, it's probably because the recovery tool is unable to download the firmware images he needs zing.net.  SanDisk has not (yet) recognized this problem.  The strange thing is that * sometimes * recovery tool works, if you already have images of the firmware on the drive... but usually it doesn't.

  So here's what you do (with thanks to Larlos for providing the firmware images and order lines to their installation).  This assumes that you're 'stuck' to the "necessary recovery" post on your connection.  If not and you are in the regular menu of Sansa Connect, first follow steps 2 and 3 in this paper: http://mp3support.sandisk.com/tools/connect-recovery-instructions.pdf, do the following:

  (1) download the zip file containing the images of the http://www.megaupload.com/?d=UNLDGZ1N firmware

  (2) search for the following files in the zip file, and then copy them into the directory of your drive "C:\Program Updater Connect Device Recovery\cmdline":

  • everest_initrd_ext_prod_1.1.1.50239.SRR.e
  • everest_vmlinux_ext_prod_1.1.1.50239.SRR.e
  • yeverest_zap_ota_rel_1.1.2.65799.tar.gz.e
  • yeverest_zap_ota_rel_ext_prod_1.1.2.65799.SIG

  (3) in the same directory, create a file named recovery.bat that contains the following three lines:

  zsi_fw.exe w everest_vmlinux_ext_prod_1.1.1.50239.srr.e everest_initrd_ext_prod_1.1.1.50239.srr.e

  zaprecover.exe t 600000 f yeverest_zap_ota_rel_1.1.2.65799.tar.gz.e yeverest_zap_ota_rel_ext_prod_1.1.2.65799.sig

  pause

  (4) connect your Sansa Connect USB.

  (5) run the recovery.bat file (double-click it in Windows Explorer, or run from a DOS command prompt).  The line of 'pause' is there only so you can see the results of running if you run it from Windows Explorer.  Expect the recovery to the end; at the end of that your connection will restart.  If Windows displays the hardware wizard detected during this process, simply cancel the wizard.

  Thanks for the help - it updated my white box to connect to the WiFi and after registration on Yahoo (without choosing any service, just updated my old email and user ID) I now INet radio with a number of stations that work fine on my home wireless network. To do this, DND to explore and syncs with WMP OK. A few quirks that I wonder about.        (1) after the firmware update, my ZAP showed that 1.2.0.58335r and OS = 1.2.0.58835 - NOW (the next day), it changed to ZAP = 1.1.2.65799r and 1.1.1.50239 = OS. Every thing seems to work even though; I have a firmware download while I was playing with the INet radio?     2) there is also a new menu item "Server Zing" that lists the name of the module, the version, and the primary and secondary server. Is this normal?  (3) what Yahoo service I - I see a small Y! symbol at the top right of the screen.                                                                                                                                               Thank you very much and congratulations Warren

  (1) no; you see the version numbers are associated with the files of the firmware (names starting with "everest" and "yeverest" files) that you have either downloaded when you ran the recovery tool, or download in megaupload.com zip file.

  (2) Yes, it's normal.  Zing is the company that allows you to manage authentication of audio stream and firmware for the connection.

  (3) the Y! symbol indicates just that when you use the Internet Radio feature, you are streaming audio of Yahoo (in fact, now owned by CBS Radio).  There is also a function of Flickr photos, which is associated with Yahoo.

• Have a new computer running Windows 7. Microsoft 4000 wireless mobile mouse: left click does not work, can not solve the problem.

  Have a new laptop with Windows 7, ASUS Intel-i5. Initially, the automatic installation of my Wireless mobile mouse 4000, which I had used with XP, has worked. Only problem was that the mouse was stubborn, when you attempt to left click: i.e. get something - and persistence was needed to get there. Now I can not at all to a left click.

• Classic connection Add-In does not work - db selection did not get recognized.

  Hi all

  With my client, many users work with the classic Essbase Add-In on their computers. The Add-In is distributed and installed with a software package. Out of these facilities, a machine makes problems. Excel version 2010 begins and the Addin too. Then under Add-Ins > Essbase > Connect the login window appears. The user name and password are given and OK button. See a list of Applications and databases. When a database is selected and you press the OK button, the selection changes to the database at the top of the page and the window does not disappear.

  This also happens with another user that can run on a different machine (so no access rights).

  The Add-in is turned off and on again. Problem stays.

  All other add-ins are disabled. Problem stays.

  Anyone seen elsewhere or have a suggestion?

  Thanks in advance.

  Kind regards

  Philip Hulsebosch

  Saw this problem occurs when there is a space at the end of the name of the server, for example

  "my.essbase.server" (the quotation marks to highlight where space is) caused the behavior that you describe.  We found that some microsoft products copy happily a space at the end when copy and pasted from outlook or word or etc... So we always adovate by manually typing in the name of the server

  Let me know if this helps - took us forever to understand.

• WLC Flex connect local authentication does not work

  Hi guys,.

  I'll give you a brief description of our current flexconnect configuration. We have APs configured mode flexconnect in the remote office and in local mode in the local office. Wireless LANs are the same in both locations and we have detected a problem in one specific SSID. It is a voice SSID and configured in 802.1 x mode that authenticates to a RADIUS server in the remote desktop.

  We detected only when the WAN line gets collapsed the IP phones unplugged wireless SSID and when the WAN line become free, reconnected.

  We have seen that we can configure Flexconnect local auth mode to avoid this problem, but it of esn can't work properly. We have set up APs in remote site with an IP address static and configured as NAS in the RADIUS server, but we did not see any which authenticayion in th RADIUS server package when change us the SSID to «FlexConnect auth» local

  Can you give me an idea to help solve this problem?

  Thanks in advance.

  Joel

  I suppose that clients connected by access points Flexconnect have problems where the WAN connection is down (?)

  It depends on your current configuration and security policy what are the feasible options in this scenario. If there is an available RADIUS server - who can still authenticate your users while the WAN line is down, you can configure your access points to access this server directly. You must use a FlexConnect for this group and configure the external server on the general tab, in the menu "AAA". You already made the point of access-static IP addresses and add them as clients on the RADIUS server, then it should work.

  Another option is that in the event of failure, access points to will authenticate the client based on a local data base and/or certificate. Also, this requires a FlexConnect group and the option 'Enable local authentication AP'. For example: If you are using PEAP and a specific user for VoWLAN account you can download the server and the certificates of CA to the WLC and add the credentials of this account to build the same configuration with the external server. Downside of this is the lack of central logging that may not match your security policy.

  Remember that the access point itself can't remember the relationship between the access point and FlexConnect group, in both scenarios, you need to configure all controllers manually with these MAC to the Group mappings. This behavior is different in comparison with the "groups of AP" what access point you remember during the passage of the controllers.

  The "FlexConnect local authentication" option on the SSID itself forces always use local authentication that has been configured on the FlexConnect group even if the connection with the WLC is available. I don't think that it is feasible to use it in your scenario.

• _RenderingSession.getBrowserContent blackBerry Smartphones (connection, this, e); does not work on bb Simulator

  Hello world

  I develop a demo of the browser to display only the text and images. I finished my app and it works very well in blackberry devices. But I want it to work in Blackberry Simulator.

  I use Eclipse 3.4.1 and Blackberry JDE 4.6.0. Windows7 Pro

  The problem is that the line I marked in red was not executed. That the app work well until this line and it crashes on this line. I used try catch, but it is not an exception. The following lines in the same function are not executed. It behaves like the function is finished.

  When I debug the application in this eclipse platform, line by line, after this line opens a new page and it says "Source not found!"

  I need to work on the Simulator, too. It is very important to continue to improve the application.

  This is the code:

  RenderingOptions renderingOptions = _renderingSession.getRenderingOptions ();

  Disable images in html format.         String useragent = "BlackBerry" + DeviceInfo.getDeviceName()+"/"+DeviceInfo.getSoftwareVersion ();             renderingOptions.setProperty (RenderingOptions.CORE_OPTIONS_GUID, RenderingOptions.USER_AGENT, useragent);

  browserContent = _renderingSession.getBrowserContent (connection, this, e);

  Thank you and best regards.

  I have solved this issue, too. I started the MDS Simulator, and then run the BB Simulator. Then, the problem is resolved.

• At the launch of Firefox, a small white window appears in the main window and the site does not work.

  I reinstalled Firefox today 3/9 and the problem persists. Date on request stamp is 3/5. That day I started to have problems. See attached screenshot.
