TI-Navigator Access Point greatest secret
« on: July 05, 2012, 08:13:36 pm »
The TI-Navigator Access Point is the proprietary WiFi router used to build a wireless network of TI-Nspire handhelds in class. It connects to the host teacher computer through USB.



In a previous news, we were discovering the included motherboard together:



And I was telling you that there was something else in the TI-Navigator Access Point...

Just think it again:
  • it's written "power by NetGear" on the case, but the 'NetGear' word doesn't show up on the motherboard... ::)
  • there is a WiFi antenna on the case, but not on the motherboard... :o
  • the motherboard has an ethernet connector, but there is no external ethernet connector on the case...  ???
  • an ethernet cable is plugged... :banghead:



The propriety TI-Navigator Access Pointer router is just built around... a perfectly standard NetGear ProSafe WAG102 router! ;D






And what if you could now build your own TI-Nspire wireless network for cheap ? ;)

Wonder how TI's gonna fare when the testing authorities find out O.O

Anyway, that's some really interesting news. Can't wait to see what Nspire developers will do with it.

Oh wow... if 3rd party networks are possible that's gonna be amazing, considering how cheap routers are. One thing that might be discouraging people from attempting making multiplayer games or online stuff is how expensive the navigator devices are.

Don't worry, I bet they made all that very legal :P
And anyway what in this packaged thing could be illegal ?
For example, if I have the right to sell a product, can't I just be selling a product of mine which improves/modify some other company's product directly, from the outside ? (I dont think TI modified the inside of the NetGear router)

Oh, I was just imagining how teachers/proctors who are paranoid about cheating would react to finding out there's basically a router inside the Navigator.

I think that the interfacing card has an important role which might be related to security and explain why non-Nspire clients can neither see or connect to this private WiFi network.


We might find out by digging into the TI-Navigator Access Point Firmware (based on Linux and uBoot):
http://tiplanet.org/forum/archives_voir.php?id=6071

Note that I don't know if that firmware is flashed into the interface card ROM, into the NetGear router (custom firmware) or into both.

Nice find! It looks like some really interesting things could be developed if we are able to figure out how to let regular routers "see" the nSpire. :)

They didn't even removed the case of the Netgear router? Oh wow. Way to go, TI.

Yes exactly. I thought I was going to find NetGear PCB/chips inside the Navigator Access Point... not a complete NetGear router :P
