Securely extending my wireless network

    I did some quick searching and didn't see any helpful information. I have 2 wireless network devices that act as a bridge between 2 network segments. I had a pretty rigged up configuration, but the past couple of days I've been trying to secure and stablize my network. I got the stability done, now securing it seems impossible.

    My current configuration is my WRT54G running dd-wrt v23 is my main router, and my WAP54G running some other firmware is configured as a wireless repeater, connecting to the WRT54G. This allows me to connect my laptop to whatever AP is nearest for better signal quality, and the signal is boosted a bit on both devices to make their wireless connection stronger. I have encryption disabled and everything works as desired.

    The problem I'm running into is I can't seem to do this with WPA PSK. The WRT54G doesn't have a "repeater" mode so I can't test the connection the other way around. My laptop can connect to both devices using WPA, but they just won't talk to each other.

    I plan to add mac filtering, I just haven't gotten around to it yet.

    Only WEP is supported if you configure WAP54G as a wireless repeater.

    WPA is only avaailable in wireless repeater mode with version 2.08 of the firmware with the WAP54G. Do not use a newer version such as 3.03 or 3.04. You can find that version on the Linksys ftp site. This is the change log for 2.08.

    Version 2.08, Jan 24, 2005
    - Improves performance when used with WRE54G
    - Adds WPA PSK support in Wireless Repeater mode
    - Fix: System log displays incorrect log time
    - Fix: When security is enabled in AP Client mode, it does not show enabled in basic page
    - Fix: In AP client mode, connection drops when connected to another WAP54G
    - Fix: IP fragmentation security vulnerability

    Looks like the modified firmware on my WAP54G is from the 2.06 version, so this makes sense. Linksys only provides the 3.04 version and it doesn't look like offers a download for the official WAP54G firmwares.
