This is a small thing, but I have often stumbled over the “SUCCESS!” message. I think it would be better to say “ACCEPTED!” or “APPLIED” As you say, it doesn’t mean that the action the user has submitted was successful, merely that the setting was applied.

There are three specific aspects to this particular function. First, if you are connected wirelessly to the router, invoking the repeater function completely resets the wireless function, because it has to shift channels to what is being repeated. When the connection breaks at the start of the reset, your laptop may switch to another AP. You may have to switch back. Second, particularly on the Mango, it takes some time for the wireless function to reset completely. You might need to wait 30 or 40 seconds for the reset to occur, when the web page shifts from looking like nothing happened, to showing the green connection. Third, you might need to refresh your browser.
