Wow! Thanks, I really appreciate it. I do think it's an issue with the security settings on the Airport. I have a wireless photo frame that works perfectly when there is no security on the Airport, but with any type of security the frame can't see my network because it doesn't recognize the type of encryption used. I chalked that up to bad programming on the part of the manufacturer, but I've now tried three different third-party firmwares on the Linksys, and had the same results every time.
Okay, in DD-WRT, click on the
Status tab, and then on the
Wireless sub-tab that appears. Then go to the bottom of that screen, and hit
Site Survey. Your airport router should appear, so then just click on the
Join button to connect to it.
If all goes well, it should show it connecting.
Then back to the
Status->
Wireless page again, scroll down, and (refresh) it should show the SSID of the airport router, along with Rx/Tx packet info etc..
