I purchased a used access point/router from a computer show. It works fine but I can't figure out the IP of the device. I can't make changes without being able to access the ROM. Is there any software available that can sniff out the IP on this router??
Thanks.

My first guess would be 192.168.X.1, where X is a small integer (1, 2, etc). Try that and see what happens. If no joy, try pinging
255.255.255.255 (broadcast ping) or 224.0.0.1 (multicast ping) and see who responds.
Another possibility on an isolated network is to use a packet sniffer (tcpdump, ethereal, etc) to watch all traffic from ethernet addresses other than your own while you power up the router.
On unix (maybe windows too?), you could try "arp -a". If there are any IP addresses that you don't recognize, they're good candidates for belonging to your mystery box.
Alternatively, most vendors have some kind of "reset to factory default" mechanism that gets the box back into a known state without knowing anything about how it's currently configured.

This is a good, free program for scanning your network:

I guess the seller removed the serial number tag so you can't identify the access-point, router, or whatever. Perhaps you could disclose the color and shape so it might be identified?

You mean other than running CMD, then typing IPconfig?

Are you using the device as a router. If you are... it's usually the Gateway IP.

What is the particular brand and model of this router/AP? A google should find the default IP.
Some IPs that may be the default:
192.168.0.1
192.168.0.50
192.168.0.100
Cheers,

Yes this is correct. You can find out simply by doing a quick search of the brand in google.

if its working, goto a client PC and check out the gateway address. That is your routers IP.....

Y'er no fun. If someone was using it as an access point, and turned off the DHCP server, you'll get nothing. Assuming it has a reset button, I would stomp on it to reset everything to defaults and start over.
(Mini-rant: Why is so many people reluctant to disclose the maker and model number? Fear of numbers?)
