I'm having trouble connecting 2 keyclones on 2 pcs...

I was using a router to splite my internet connection and it worked fine, but i got a new cell phone that i can use as a connection to kind of free up some bandwith on my dsl connection.

When i use the dsl on both pcs the keyclones connect fine, when i use my cell as the connection on the 2nd pc the keyclones will not connect... I'm putting in the ip address of the second pc from the first and vise versa and the connection pops up for a second and then goes away.

Any ideas? in my network connections i just disabled the dsl connection on the 2nd pc but i didn't unplug the cable on anything so the LAN should still be picking up right? Help plz
