This is pertaining to a smart phone with data. 

My phone is connected to my WIFI which lacks internet currently. It is also connected to the cell network and using it for data. When I ifconfig it tells me I am connected on wlan with 192.168.1.4 and rmnet at 10.124.121.12. I am trying to ping a device on 192.168.1.55 for purposes.

If I turn off my cell network I can ping it fine. With my cell network on its unreachable. 

How do I get my android to allow me to ping 192.168.1.55 while being on the cell network? I have only noticed this since the internet went out on my WIFI so its a strange and new problem.
