Access Point/Router IP needed

17 Mar 2005 1:32 PM

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:

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.

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?

NMap works nicely for scanning for IP's.

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?)
