Problem with WEP encryption on WRT54G

    I'm using HyperWRT already for months with WPA encryption and it works suburb.

    Because of the extension of my network I’m have purchased a WAP54G and configured it as a “repeaterâ€. I have everything working without any wireless security to test the set-up.

    And because the a WAP54G in “repeater†mode doesn’t support WPA encryption so I want to use WEP.

    I have configured the WRT54G to use WEP with a 128 bits key, configured my PC (winXP, SP2) to use Network Authentication “Openâ€, Data Encryption “WEP†and copied the correct key. The problem is that I can not wireless connect to the WRT anymore. When I connect by use a network cable and change the security mode back to “WPA†or “disabled†I have no problem connecting.

    Therefore I have the following questions:

    - What is going wrong and how can I fix it so I can use WEP?
    - Why is WPA not supported in “repeater†mode of the WAP54G and will it be supported in future

    Thanks in advance for your help

    I am not claiming to be a WEp guru here but I believe only 64bit WEP works in M$ Windows. I believe M$ went this route for compatibility with other WEP products.

    I gave up getting the 128 bit stuff working on my home net and just leave the 64bit WEP in place

    Windows XP supports 128bit WEP encryption.

    MegaByteNL, are you able to connect to the SSID using WEP but are unable to obtain an IP, or you are not able to do both altogether?

    Is the Key index under WZC, assuming you are indeed entering the correct Key. Is it matching with the Default Transmit Key value (under WEP) used by the router.

    Another thing is make sure the option Enable IEEE 802.1x authentication for the network (under Authentication tab of your wireless connection) is disabled - but it should be disabled by default under SP2.

    Try disabling Windows Firewall and see if that helps, or even reverting back to Linksys official firmware.

    I'm not abel to connect to the SSID. I'm using static IP addresses.

    When I enable WPA again on the WRT54G I'm able to connect within a few seconds.

    The firewall is turned off.

    I will go back to original Linksys Firmware on my WRT54G to test. For my WAP54G I'm using the Sveasoft-firmware because the original Linksys does not let me change the channel in "repeater" mode.

    Do you have any idea why WPA is not working in repeater mode on the WAP54G?
