Cannot communicate on LAN when WIFI doesnt have internet

Question

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.

Answer

I have the same setup. I have a local WiFi network that is not connected to the internet. I found that if you go to settings on your phone, then select “Developer options” and tick “Cellular data always active” that you will have access to the WiFi network and the cell network simultaneously.



On my LG, I can be on the web with cell data and print to the printer on the local WiFi network. I just now tested a ping just to make sure and it works just as you would expect.
