How to: retrieve IP from wireless router

Hello,

I have been asked to go through my companys multiple locations to find out the IP Address for each Wireless Device. Each location is on a different network and therfore so is the Wireless router. However I'm not sure how to find the IP Address.

All of the wireless routers is set to disable DHCP.

I was wondering if there is software out there that would help me with this?

Are they cisco Wireless AP's or DLINK/Linksys wireless routers?

When you mean that your company's location are multiple, are they all available to be seen locally (i.e. subnetted, NAT'd) or do you have to travel to each site and check?

One solution that could work is called Spiceworks (www.spiceworks.com). It's a Window-based application that has a sort of hunt/discover methodology for determining the types of hardware and software equipment is running on the network.

If the network is available locally (i.e. subnetted), you can just add the other IP ranges into the 'finder' portion of the application and it will hunt down the hardware available/accessable on the network. If you have to travel to each site and find out, Spiceworks could be run from a laptop and hooked into the network to do the hunt and discover.

DLINK and Linksys
chances are they ips are

192.168.0.1
192.168.1.1

or similar variations
or 192.168.100.1

run ping commands on those ips, i am almost 100% sure you will pick them up

shroomduck,

this will not work because the wireless router ip will be an ip from each network. example see below:

192.168.22.0 subnet  building a
192.168.42.0 subnet  building b
Oh, you have manually assigned IPS to the devices? Thats a little different then.

I would recomend going to the device, plug in a laptop to one of the ports and run a tracert to another PC.

So say your pinging 192.168.42.122 and your PC is 192.168.42.56

tracert 192.168.42.122
your first hop is usually your Default gateway (router)

shroomduck,

what if there are multiple wireless routers on each network. would tracert still work to show both wireless devices?
you would have to goto each device. when you run the tracert command, it traces every device it has to go through to get to your specified destination.

mwecomputers,

the software that recommened did not work. do you know of any others?

shroomduck,

to do this would i actually have to connect directly to each wireless device or just make sure i'm connected with that subnet?
yes. goto the device and follow the steps I outlined and you will be able to tell in no time!

shroomduck,

I did as you said but when i ran tracert it did not supply the wireless device ip, just the main router ip.

mwecomputers,

do you know of any others? i did use this software and it worked. HOWEVER, it did not display the wireless router within the correct section. I had to go fishing for it.
The only other one I know is called Network Magic:
http://www.networkmagic.com/

Network Magic Product Comparison:
http://www.networkmagic.com/product/compare.php
http://home.comcast.net/~jay.deboer/airsnare/

New MAC addresses will appear in the main 'tree' pane on the left, and the MAC + IP address will appear in the lower pane on the right side.

If it proves useful, I encourage you to use the Help->Donate link in it since you're using it in a commercial environment and the author released it as beggarware. It doesn't work with all cards, but install it on a couple different machines and have it listen on both the wireless and wired sections (i.e. using the wireless adapter on one computer and the wired NIC on the other).

Darr247,

no dice, this program would not even run it was missing DLL's. No of any others especially ones that are still in business with possible updates in future?
It's run fine on every laptop I've installed it on...  what DLL's did it say were missing?
Some visual studio runtimes?

If it was the common dialog file run Start->All Programs->AirSnare->AirSnare Updator[sic] and see if that installs the file[s] you need to run it.

It's not that the guy is out of business... it's essentially free, so there's not much incentive for him to actively support it.

Darr247,

tried it again and no go. Moving on now to some other ideas if someone has them.

If no one else has any other ideas then i'm going with mwecomputers: since his program actually works but is just a little anoying since wirless routers don't actually appear in the section it should.
No problem. Be aware Network Magic loads as a service and 'phones home' every time you reboot any machine it's installed on.
Well I am not sure why my method didn't work for you. I just tested it here with a Dlink wireless router and it picks it up fine.
In order to tracert to every machine they would need to already know the IPs of every device on the network.
Or if they had a list of all the device/host names they could just ping all the names to resolve their IPs.

It appears that's what they're trying to document, since it was apparently not done as they were assigned (else when the person who did all the setups moved on, they took the list with them... but 'why' doesn't really matter, all we know is they want it done :-).
