Please I have a problem with one of my phone's hotspot.
The phone is Infinix Hot2.

The problem is that whenever I switch on my hotspot, I cannot use it in any other device. Let me make it clearer.
If I want to use the phone hotspot on my computer, it will connect but I can't access internet with it. It'll sometimes show connected but with "No internet access." Some other times, it will show internet access but can't open any Internet page. If I use USB tethering between the phone and the computer, I'll be able to use the phone data to browse with my computer.

The problem is not from the computer cos I can access the internet using other hotspots. I also confirmed that other phones can't access internet through this infinix hotspot.

Please is there any setting I need to activate to make this hotpot work.

Note that the phone is not rooted and has never been opened as in repairs.

Thanks for anticipated technical responses.
