I just purchased the DAP-1522 and have the same missing "wireless network setup" menus problem. However I can't display it with IE (version 8 ), firefox, chrome, or opera. I'm using it as a bridge and it is running version 1.21 firmware. I backed the firmware version down to to 1.20 then 1.10. Same problem in all browsers. Though folks here had it working with IE, I get a script error indication from the browser when I open the wireless setup screen. The bridge is working, but it would be nice to know some of the settings it chose.
Anyone else have a problem with IE also? Any solutions/thoughts?
