Problems authenticating using WPA/TKIP with AT & T 2wire router

I have problems trying to authenticate on AT & T 2WIRE router. Before, I was using a Linksys router on Comcast and had no problems, but after switching to AT & T and their equipment, my computer vista no will authenticate not. I don't get an other error message that Windows could not connect to the network. I have a Windows 7 box, Epson wireless printer and XBox which can connect without a problem. It's just that Vista machine which does not connect.

I tried to update the wireless network card drivers, I restored the computer to factory settings, I tried everything. I had success when I step down to WEP security, but it's not the level of security that I want to keep. The real odd part is that it has worked well with Comcast and Linksys but not with the 2WIRE router.

Any help would be appreciated.

Joe

Hey Joe,

We do not recommend the use of WEP. WPA or WPA2 are more secure. If you try WPA or WPA2 and they do not work, we recommend that you upgrade your network card to those who work with WPA or WPA2.

For more information, you can consult the following link:

What are the different wireless network security methods?

http://Windows.Microsoft.com/en-us/Windows-Vista/what-are-the-different-wireless-network-security-methods

You can consult the following links to set up a wireless network using WPA or WPA2.

  • Problems in using the APEX with glassfish server listener

    Hello
    I try to install APEX with listener application on my Oracle R12 application server. I installed glassfish 3.1 (zip file) and deployed my interlocutor on glassfish using the administration console
    http:// < Host >: 4848

    But I am not able to run the following links to get the status of the listener
    http:// < Host >: 8080/listenerStatus

    I get the following error when I try to connect using my user adminlistener who I defined under the Admin group, in accordance with the installation guide.
    HTTP status 403 - Access to the requested resource has been denied

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

    type of status report

    messageAccess to the requested resource has been denied

    descriptionAccess to the specified resource (access to the requested resource has been denied) was banned.


    --------------------------------------------------------------------------------
    Oracle GlassFish Server 3.1
    Also, when I try to start the administration console application using the link http:// < host >: 8080/apex
    I get the following error

    application = 4500 workspace = 10+.
    Error ERR - 1014 Application not found. +

    OK+


    Anyone know what could be the problem? Earlier, when I did the installtion even on my personal computer that runs on Windows OS I had faced some questions like this and was able to resolve by reinstalling glassfish with port 7878 place default 8080 HTTP and that solved the problem.

    But this time, I try to install on the Linux server and since I used the option of the glassfish server .zip file I don't have the option to configure during the installation. If you think that the problem is due to the conflict to port 8080, then can you please tell me how I can change the HTTP port without having to reinstall the glassfish Server?


    Thanks in advance!

    Hi reda,.

    http:// : 7878/apex/listenerStatus (I changed my HTTP port for 7878)

    But I have error which I run this URL below.

    HTTP status 403 - Access to the requested resource has been denied

    I'm sorry I have not answered your question 403, but I thought it should be a primary target in order to get your APEX installation up and running first.
    As you have moved this issue, it is logical to continue on other issues in your deployment.
    You say that you are trying to connect to listenerStatus as "adminlistener" with the group "Admin". You must use a user with the 'Manager' of the page group.
    However, if you have "Admin", you can access the 'status' tab in 'listenerAdmin' that contains exactly the information you see in 'listenerStatus '.

    Also, when I run the URL Listner Administrator page loads properly, but all fields are disabled. So I can only see the page, but not to make changes to the fields on tab 'connection '.

    You can change the JDBC settings in this tab? You must open the subform to display the fields.
    And you are able to change any settings on the other tabs?
    If so, everything works as expected. It is not possible to change the credentials of database using "listenerAdmin". The shape looks like the one you get in "listenerConfigure", but it is implemented differently, so what you see is the expected behavior.

    However, I can click on the 'Apply' button on this page and when I do that it takes me to the login user APEX screen. This is how it should be?

    Yes. What is this "Apply" button to reset the connection pool to use the current JDBC settings, which you should be able to edit as shown above. Therefore, when you apply the changed settings, the listenerAdmin will take you to the start APEX page to check that everything works (always) and continue to use APEX.

    We tried IE8 with system 11. It simply doesn't get it. IE8 is not officially supported yet. And over the years, I have learned this lesson: never use a new browser, unless it is officially in charge.

  • Wireless LAN on Equium A210-1AS connection with WPA-TKIP encryption problem

    I have a 1AS Equium A210 with Vista but cannot connect to the internet via a wireless router cable modem NTL using WPA-TKIP encryption and 5600 philips.

    The laptop shows the base station wireless with a beep sound intense but said that the base of the station is not responding or is hidden when I try to connect to the internet.

    I'm using the correct password.
    I am able to connect to the internet via the base station when connected via the ethernet cable. Other old computers connect wireless with no problems.

    I heard that some combinations of chipsets with Vista can be the cause of some of these issues.

    Clear advice or ideas on what I could try to get wireless internet would be greatly appreciated.

    Have you checked to connect the laptop to the router WLan with WPA encryption settings? Please do. You must disable the WLan encryption to test the WLan connection

    If the laptop could connect properly, then encryption is certainly the reasons why the laptop can not establish the WLan.

    Maybe your wireless network card does not like this on the encryption support or you simply have to update the Windows operating system and the driver WLan.
