I need my ipad to connect to a wireless access point that is not connected to the internet.
The Wifi connection is established fine and I can access other devices on that LAN.
While on that LAN, the ipad cannot access WAN sites through 3G.
Is there a way I could have wifi on lan while accessing wan with 3g?
The iPad doesn't support simultaneous connections on Wifi and 3G. If Wifi is on, 3G is off.
Same for iPhone?
Well, I was in fact capable of doing exactly what I wanted.
The Wifi connection on the iPhone/iPad must be configured as a static connection. You must specify an unused IP in the range of the wifi access point (e.g. 192.168.0.2). Specify a mask (255.255.255.0). Do NOT enter any router IP.
Once connected to that wifi network, you can access other devices connected to the same wifi LAN (e.g. 192.168.0.*).
And, as I needed, WAN is accessible through 3G!

Claude, im glad you are getting what you need, but you are getting it thru wifi. You are not using 3 g. To prove the point, turn the wifi radio off, and see if you can get to those devices.
The wifi and 3 g radios are mutually exclusive.
As pjl123 said, and as I stated yesterday, simultaneous wifi and 3G is impossible on the iPad and on the iPhone. All of your access is going through Wifi at the moment.
My wifi access point is not connected to anything. I did NOT connect it to any other wifi network.
I have an ethernet arduino board connected to the wifi AP with an ethernet cable.
My iPad and iPhone are setup to connect to the my isolated wifi network.
Every component above is setup to use static IP addresses.
My iPhone and iPad do not specify any router IP.
My iPhone and iPad both can access WAN.
If I turn off 3G, they cannot access WAN.
Both can connect to the router (admin) and to the arduino ethernet.
This does indeed work. I do it all of the time. 3G for Internet and wifi for LAN. As noted as long as you use a static IP and leave the router IP empty, it will work just fine.
WIFI for LAN, 3G for WAN
