The following is from SMC's FAQ on their website. I home this helps. I would first reset the router and proceed as if it were new. If the router is already configured it may be set up not to respond to pings in which case pinging it would not yield anything. <br>

You will have to use a paper clip or a similar pointed object to do the reset procedure.
<br><br>
<b>Hard reset:</b>
Insert the paper clip to the reset button and hold it down for 15 seconds,
while the paper clip is still in unplug the power cord that goes in to the router,
now wait for 15 more seconds and then give the power supply back to the router,
again wait for 15 more seconds and finally let the clip go.
You will see the router's LEDs flashing. If this happens it means that we have
successfully completed the reset.
<br><br>
<b>Soft reset: </b>
Login to the router, go to the Tools menu, click on configuration tools and select the
option restore router to factory defaults to reset the router.

The password would be blank/admin/smcadmin by default.
Blank password implies that you need to click on login without giving any input.
<br><br>
But, if you have set a password on your own and not able to recollect it,
try resetting the router.

As I'm reading your message, you received a device that's already<br>
configured and do not know its IP address, which you presumably need to<br>
reconfigure it.<br>
<br>
My first thought it "plug in a crossover cable from the machine to a<br>
workstation rnning tcpdump and watch for packets that contain the IP."<br>
That may or may not work -- I don't know how noisy the router's going to<br>
be, or what kinds of things it's going to be looking for internally to<br>
generate traffic.<br>
<br>
My second thought is to think "password recovery" -- there's probably a way<br>
to reset everything to factory defaults described in the manual, which may<br>
be faster and more efficient than trying to find traffic.<br>
<br>
Many of these devices come with a (Windows) disk for initial setup, using<br>
UPnP or something similar to do initial setup. I don't know about the<br>
specific device, but that may also be a good option or you.<br>
<br>
Finally... how much is it worth to you, to do this? Sometimes, receiving<br>
used gear turns out to be an excuse to go to FreeGeek to get rid of it....<br>
