Running a Minecraft LAN Server?

So here is a complicated one, I'm attempting to run a LAN server for minecraft, but I run into the problem of different devices on different subnets. Here is the breakdown:

NETWORK SETUP
- Free internet through my apartment complex
- We have a Hub/Switch that allows myself and other tennants in our building to connect to the internet
- This Hub is in my unit and is wired to allow the other units to connect
- Belkin router connects to the hub and allows wired/wireless access
- All devices are connected wirelessly to this router

PC's CONNECTION TO THE NETWORK
HTC Glacier (T-Mobile MyTouch 4G) connected wirelessly to the Belkin Router
This Device is Tethered to the PC using an application called Tether and the PC has the software installed and it is working and allows me to access the internet

HERE'S THE PROBLEM
Because I'm using the application and tethering, the PC itself is on a Subnet of the network and is assigned an IP of 10.0.0.1 and Gateway of 10.0.0.2 all other settings are the same. Due to this, I can't access the other PC that is connected wirelessly with its native wireless. The other PC is assigned an IP address directly from the router. Therefore, I'm unable to see the other PC from my own PC.

So my question is this:

Is there a way to allow to access the other PC, in-turn run a LAN minecraft server accesible between the two devices? And if so, how might I accomplish this?

NOTE
I have attempted to set a static IP already

If you need more details, let me know.

If you are tethered through a mobile phone to the same Belkin Wi-Fi router that another PC is wirelessly connected to, you should have no trouble at all connecting to a minecraft "server" on the other PC. Note that I said "server", it will not work with "Open to LAN" from a minecraft client on the other PC, because that is found through broadcasting, and your PC IP is NOT directly on that same LAN. But if the other PC is running a minecraft server, you should be able to connect to its IP address (or IP: port if port in its server.properties is different than default 25565) just like you should be able to connect to a minecraft server on the internet.

Note that you will not be able to run the server, because you are behind NAT on the phone and have no way of overriding that or port forwarding.

Attempting to manually set your IP on your computer would not help anything at all and would likely make you unable to connect to anything, locally on that router or on the internet, because your phone would not respond to a tethered IP it did not assign itself.

If your PC does not have Wi-Fi, why not just pick up a USB Wi-Fi dongle? Then even "Open to LAN" should work, at least for Windows computers (I have no way to test that with just 1 account).
