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.
