I've got a Samsung Galaxy Note 10.1 (2014) and would like to connect to a private network through WiFi for development work, but still have access to the general Internet through the 3G/4G cellular radio for other apps. So far, it does not seem possible. Connecting to WiFi seems to route all data through WiFi to the private network, cutting off the Internet. Is there a way to have both radios working and routing packets separately on this Galaxy Note, or any other Android device, short of customizing the network stack software?

It sounds as if your private network does NOT provide Internet access, and you'll only be traversing the local subnet. If you do NOT need to access anything other than a single subnet, why not just CHANGE the gateway for your local WiFi so that it points to the gateway of the 3G network instead?

So anything you access locally won't need to hit a gateway router, and anything ELSE you need will have to head out on the Internet. .... Except that it doesn't seem Android wants to hold more than one IP address at a time?
Hmm, so maybe not. :(

Starting to look like bad news...
Of course, what you COULD do is set up your own WiFi router that handles this split for you, acting as a client on the office network (with their permission I hope) and passing Internet requests through the phone's 3G. But that's assuming you're using a second device. :(
