Enable usage of mobile data while connected to a WiFi without internet connection

Question

It is possible to allow my device to use mobile data while connected to a WiFi hotspot?

The reason being is that the WiFi hotspot I connect to does not have an internet connection. So I want to be able to access the internet while still being connected to this WiFi network.

I can see that after Android 10, there is a feature called dual acceleration which allows this for certain app like Instagram, Chrome and Facebook. I want to be able to do it for any app. Is there a way of accomplishing this?

Answer 1

Use mobile data for specific WiFi network

1. Go to Settings > Connections > WiFi
2. Tap and hold your WiFi network name until a menu appears
3. Click “Manage Network Settings”
4. Make note of your IP Address and Subnet Mask
5. Change “IP Settings” from “DHCP” to “Static”
6. Remove the IP address from “Gateway” so that “Gateway” is blank.
7. DO NOT CHANGE any other settings. Be sure to leave “IP Address” or “Network Prefix Length” alone. The “Router” setting should be BLANK/EMPTY!
8. Save your changes. Android should no longer attempt to connect to Internet through this WiFi network.

Recent versions of Android OS also allow users to force the OS to always use Mobile Data. This is not as ideal as the iOS settings above, so only use as a last resort. You must toggle this setting whenever you DO want to use a WiFi Internet Connection.
