  • 1.  Laptop does not get DHCP for wireless adapter and does not hibernate.

    Hi,
    I tried to test SEP in unmanaged mode on my laptop running win xp media SP2. The application worked fine but the wireless adapter fails to get dhcp lease. Smart traffic filtering for DHCP is enabled on Network protection and also created a rule for the same. After initial troubleshooting found that whenever I enable and then disable SEP, the adapter gets a DHCP lease. It again fails to renew after the expiry of the lease and I need to enable and disable SEP again. I tried disabling just the Network protection but this does not help.
     
    The second issue that I am facing is that the laptop does not hibernate by pressing the power button when SEP is installed. Checked all the hibernate settings. If I uninstall the SEP, the laptop readily hibernates with the power button. There is also sufficient disc space for hibernate to function.
     
    Laptop details.
    OS: Windows XP Media Center Edition Service Pack 2 (build 2600)
    Model: Hewlett-Packard HP Pavilion dv2125tx
    Adapter: Intel(R) PRO/Wireless 3945ABG Network Connection
    SEP version: 11.0.780.1109
     
    Thanks

    I got answer to my first problem.
     
    This is what Symantec says
     
    Resolution:
    The unmanaged client installed from the CD does not include the rule to allow EAPOL* communication.
    There are 4 options below to resolve this issue:
    1. Install a managed client with the EAPOL rule allowed
    2. Install an unmanaged client that has been exported from the Symantec Endpoint Protection Manager (SEPM)
    console—It will include a rule to allow EAPOL
    3. Generate a policy file allowing EAPOL from SEPM that can be imported on the client so that the traffic is allowed
    4. Set a rule on the client to allow all traffic
    * The Rule is called EAPOL in the management server.

    I have tried this fix on two different machines and it does not work on all wireless connections.  I have a number of clients that have laptops that never come into the office and at least 9 of those will not connect to a wireless network somewhere.  We are holding off on deploying or selling the product until such time as we can get resolution on this and multiple other issues.

    Hi,
     
    I guess this issue relates to wireless connection using WPA encryption. Guess, it should work with WEP but again...thats notall secure.
