When using nmap and autoscan on my wifi network I can see all regular devices connected to it - the router, laptops and even the N810 (that btw for some reason calls the network card 'Danmark A/S' ).
But..if my girlfriend connects her iPhone to the wifi network it doesn't seem to get an IP address assigned to it in the 192.168.1.x-range.

After she connected we went to whatsmyip.org on her phone and it gave an IP address of 71.202.something.something.
First I thought that maybe it was a static IP address and did an nmap scan of the exact address and it found it.
It also mentioned comcast - which is the internet service I use.

Later on she left and I for some reason did the same nmap scan of it - and nmap said it was still 'active'.

Could it be that the 71-address that it showed on her iPhone was not tied to her phone per se - but rather the router (which means I still got no idea what the phone's IP address is)?

I also can't figure out why her iPhone can connect to my router - without getting an IP address in the range it uses.
How can I ever scan my network for any devices connected to it if they can be connected using an IP address outside of the expected range?
Normally I just do for instance an nmap -sP 192.168.1.0/24 scan - can I throw the net wider?

(And yes; of course I know about WEP/WAP, so please if you reply do focus on the above).

I would check the router's IP table after she connects to your WLAN and see if more info can be found, seems odd you wouldn't be able to see it with the scan you used.

I'll check that tonight, thanks.

It just baffles me that I can't see it connected - and I hate being baffled

I think it's whatsmyip.org, not whatsmyip.com.

That site will show you the WAN (Wide Area Network) address of your router, not the private LAN address (192.168.blah.blah) of your device. For more info, look up NAT (Network Address Translation).

On her iPhone, maybe check that Settings->Wi-Fi->Ask to Join Networks is set to OFF. You can also make sure on this screen that she's connected to your network.

Thanks, yes org - not com I believe. I'll correct it.

Well that explains the 71-address. One less thing.

I'll double-check again that she's on my network when she switches to wifi. If she is..and I still can't see the iPhone then not sure what to do.

I wonder if autoscan has iPhone fingerprint data.

I ran nmap and it didn't see my iPod touch. I pinged my iPod touch and it responded. I then reran nmap and it saw my iPod touch. I'm not sure an nmap ping is the same thing as a ping ping.

How did you ping your Touch without seeing it in nmap? You must have found its local IP address somehow. Where can you see it (on the Touch)?

Was your touch given an IP address within your router's regular band (192.etc)?

Settings->WiFi looks like this:



When you click on the blue button that I circled in yellow, you should see this:

Got it worked.
I was able to see it tonight and added the fingerprint for iPhones.
Then later another person came over and I had them log on..and autoscan picked it up right away and labelled it 'iphone'. Neat.

Thanks.
