Good info.

Let's simplify the interoperability somewhat: Set both routers to use WPA2-Personal(Pre-Shared Key Only), and AES only. Not WPA/WPA2, just WPA2.

This way we'll eliminate any mis-matches in encryption methods and the like, which have confounded many others before you.

Next, find that status screen (or log) on the Linksys, so that you can know *for certain* exactly what is happening (or not).

Cheers
