A wi-fi router has been setup with a number of windows machines connecting to it. How do I use windows command line to list all the computers (either by hostname or ipaddress) in the wi-fi network. OSs on the network are XP, Vista and 7.

Well I have used following procedure usually:

  1. Go To RUN
  2. Write CMD
  3. Ping the server if you know or your gateway. Even if there is requested timed out.
  4. type "arp -a "
  5. It will usually list down all the IP's and Computers with their Mac Addresses

If you want to use GUI one tool I recommend is : IPScan

Although it a light application 433KB almost but a freeware and very effective and always work for me. 100 % result!

I don't get it. Pt. #3 says ping server (in my case it's the wi-fi router ip). Did that. Pt. #4 says type "arp -a". Did that, but I get an error that arp is not a recognized command. –  Thomas Sep 28 '11 at 17:07
Did you type without the quotes? Do it without the quotes –  aibk01 Sep 28 '11 at 17:08
yup .. no quotes.... to confirm again .... I simply type "arp -a" (without quotes) .. into windows command line? –  Thomas Sep 28 '11 at 17:10
Well works fine for me it actually the Address Routing Protocol command, why not use IPscan GUI ? –  aibk01 Sep 28 '11 at 17:18
Well I think you are also using some WIFI encryption key on you network too. That usually prevents the command to execute –  aibk01 Sep 28 '11 at 17:19

net view will probably show most of them.

... does net view require any folders to be shared on the other PCs in the network? ... I tried it and it lists only my PC as \\<PC NAME> –  Thomas Sep 28 '11 at 17:08
But it will only list the names, not the IP and Mac addresses but it works. Good answer –  aibk01 Sep 28 '11 at 17:09
