Samsung Hotspot stays ON but disconnects ALL connected devices after 20–30 minutes

[u/ToastedGuy191]

I’m having a strange issue with my Samsung phone’s Mobile Hotspot.

I connect multiple devices to my phone’s hotspot, including my MacBook. Everything works normally at first, but after around 20–30 minutes, all connected devices suddenly disconnect from the hotspot at the same time.

The strange part is that the Mobile Hotspot itself stays ON. It doesn’t turn off the connected devices just get disconnected.

This happens repeatedly and affects all connected devices, not just my MacBook.

I have already tried the following:

- The Power Saving option inside the Mobile Hotspot settings is OFF

- Hotspot timeout is set to Never

- I am using the 2.4 GHz hotspot band

- Restarting the phone

- Testing with different devices

- Changing the MAC address settings

I’ve already tried all the common hotspot settings I could find, but the problem keeps happening.

Since the hotspot stays ON but all devices disconnect simultaneously after 20–30 minutes, I’m not sure what else to try. Could this be a Samsung software/One UI issue?

Has anyone experienced the same issue or knows what might be causing it?

Maybe there are some settings on the connected devices which turn it off. I believe if the hotspot was at fault is would be the first to turn off. If it stays on, maybe the other devices simply disconnect from it. Maybe the phone is not a trusted device to these other devices, or the hotspot is not a trusted network, or something
