WPS? Strange that there is a button 'Add Wireless device with WPS' in the webinterface then??
Why make 2 buttons, that I have yet to see actually work? (combined with a Canon MP620)
And why is there no mention in either the
english nor the
german documentation about this button?
The mysterious button on the DIR-825 has quite a bit of rumor's around it (
1,
2,
3,
4, etc.)
It might be just a button that blinks the light that's under it for a minute or so and does absolutely nothing OR it could be a button that sends a log file to your mother with all the diry sites you visited.

There is no way of telling what this button does without any clear documentation...
