No internet access / limited access - Windows 7 Entreprise RRS feed

  • Question

  • I have a very strange phenomenal using Windows 7. My router has the usual security settings WPA/WPA2, TKIP/AES and other devices are able to connect to it. However, my HP EliteBook P221 laptop, running Windows 7 is not able to connect to the wireless network. It prompts for the passphrase which I enter correctly and after that it display the message "Windows is unable to connect to xxxx". If i disable the security settings in my router, the laptop has no problem connecting to the internet. The laptop has no problem connecting to internet via the LAN cable too. Can anyone help?

    Appended below is my ipconfig connected via LAN cable:

    Can we connect to the router before ?

    Please take the following step to have a check.

    1.First of all ,reset the router configurations .
    2. Reinstall the network adapter driver from the device manager .It is recommended to download the driver from the manufacturer website .
    3.Running the built-in troubleshoot tool to have diagnostic and fix.
    Control Panel\All Control Panel Items\Troubleshooting\Network and Internet\Network Adapter.
    4.Refer to the following link to reset the Tcp/IP stack.
    How to reset TCP/IP by using the NetShell utility

    If the router is never been connected with security settings enabled ,there is a possibility that the driver is not compatible with this setting, it is recommended to ask for help from the HP forum at the same time .

    Best regards

  • I think that's not the correct model, can you provide again your HP laptop model?

    everything normal before? did you try system restore?

    I suspected this issue maybe related to 3rd party software or security software

    try to login at safe mode with networking, if no more issue at safe mode with networking, try to disable your antivirus or uninstall to test, try also perform clean boot in normal mode

    to isolate driver issue, I suggest you update the driver

    Run this basic wireless issue from HP

    please share what step you've done and what is the result
