Trouble finding the ip adress to my wireless router

use the network utility app to do a traceroute to a website like www.google.com, your router should be the first ip address to show up

 

Make sure you are using your wireless connection. Go to your Terminal and type the following command:

This lists the entries in your arp table; on of the ip addresses being your wireless router. Note that this only works if your wireless router is not in bridging mode (like my airport express).

Give it a try...

 

ah, so your wireless router is seperate, just like mine

I guess it must be in bridging mode, so when I need to get back into the config program for my airport, one of the following things normally works for me.

Try unplugging the ethernet cable from it, then join onto the wireless network. If DHCP usually comes from its ethernet port then it will hopefully revert to a 169.254.x.x rendezvous address, and so will your laptop. If it was an airport then airport admin utility should suddenly be able to see it, it might also now show up in the arp table.

you could try doing a ping scan with Nmap or some other similar network utility (not included in osx) if it has some kind of intrusion detection or firewall built in then it may ignore you thinking its a hacking attempt though...

if you can get into your routers config pages, it may have somewhere in it a list of connected devices, your wireless bridge may be one of those. this depends on your router.

if you connect your computer into its ethernet port, then you should get more useful results from arp -a

hope one of those works, let us know
