CHDK was able to see the available networks, but I still got a wrong password message when I tried to connect.
Damn, I made another mistake. The network testing code was wrong.
I can't see why the Canon software doesn't see the network though.
Try with this version, it should be ok now.
Are you "up" to doing a patch file now or would you prefer to post the code and have me do it again?
I attached a patch file, but please check if it makes sense. The diff refers to version 3118
