How can I locate my lost iPod touch within my WiFi network range?!

Question

I am still using my 1st gen iPod touch from 2008 for apps and music and other uses.  I rely on it quite a bit although of course I have a separate cell phone for now (will eventually get an iPhone).  However, I synced it with iTunes right before going on a long shopping spree Thursday afternoon then hooked it to my car's stereo system to listen to as I often do.  Upon returning home, tired and with multiple bags, I was trying to juggle them all on several trips from my car to front door (about 30 ft.).  The iPod touch always picks up my WiFi network in my car as soon as I pull in, and with my hands full on my last trip I realized I'd forgotten to disconnect my iPod touch so I could bring it in too.  I'll admit I was getting bogged down and annoyed so I disconnected it then remember also dropping some bags and picking them up from the parking space.  An hour later, after finally getting most bags and myself at least somewhat settled, I remembered I hadn't reconnected my iPod touch to its JBL docking system.  I soon realized I couldn't find it in the house and went with a flashlight to look in the car and outside between the house and car.  I searched for hours in all likely places and again the next day.  I also thought about an hour after losing it to check AirPort Utility's advanced pane which includes the logs, wireless clients and DHCP clients.  Sure enough it was still picking the device up, every 30 minutes or so periodically showing "binding added" and "binded dropped" for my iPod's IP address via NAT, and also "associated with" and "disassociated with" the iPod's unique MAC address.
My worst fear was that I dropped it outside and someone dishonest took it, but that seems unlikely because I really don't have those kinds of neighbors and I searched immediately for it everywhere it could be (in my car, under it, outside everywhere I walked, in the house in the oddest places like under furniture, in discarded shopping bags, the trash can and even the freezer!  Sure enough, for 13 hours AirPort Utility showed activity contacting (or detecting) the device as mentioned above, until about 9:30 the next morning.  Since then there has been no log activity detected, and the device itself listed with MAC address has also disappeared under the "DHCP Clients" pane of AirPort Utility. I realize this could simply be the battery dying after all this time (although it should be in sleep mode), but the point is it was close by for all that time even after I'd searched for it, so it is unlikely someone found it easily after I searched everywhere I'd been in the short distance from parked car to home.  It also has a black rubber "suit" so the entire thin 8GB device is thin and completely black all over, further disguising it, especially at night.
My question is that since this is not an iPhone and I cannot "call it" to find it, and it is only a 1st gen. iPod touch without a built-in speaker to make loud noises unless hooked to headphones or a line output, how can I find it?  It does make the tiny super high-pitched digital beeps when I get a "push" notification but I don't see how that does me any good unless someone from an app I use tries to contact me while I'm in extremely close proximity to hear those faint tones. Anyway, I really do need it and it's driving me crazy knowing it is within such a short range from me either inside my house or car (or outside in a short straight path from car to my doorstep) yet I am helpless.  Is there anything anyone can suggest?  It's almost worst than knowing I lost it anywhere, because I know it's here, but want to find it soon before someone else does (if outside) or the trash gets thrown out (if it fell in there) or it gets run over if on the street somewhere I missed. 

Answer 1

There is no way to automatcally locate it.
Since WiFi does not travel far talk to your neighbors. Perhaps one of them (or their children) found your iPod.
If this does not work make a more thorough search of your house to find it.
