Hotspot disconnects when another device joins the shared connection

A common situation goes like this: your phone’s hotspot works normally while a single laptop or tablet is connected. Internet access feels stable, and everything loads as expected. But the moment a second device joins the hotspot, the connection suddenly drops. Sometimes all devices disconnect at once. Other times, the hotspot turns itself off or reconnects repeatedly.

This behavior usually isn’t random. It happens because the phone struggles to manage multiple connections at the same time, either due to power management limits, network conflicts, or carrier restrictions. When another device joins, the phone attempts to reassign bandwidth and IP addresses. If something fails during that process, the hotspot resets to recover.

Check Power Saving Restrictions

Many phones quietly limit hotspot performance to preserve battery life. When a second device connects, the system may interpret the higher load as excessive power usage and temporarily shut down tethering.

  1. Open Settings.
  2. Go to Battery or Power Management.
  3. Disable Battery Saver or Low Power Mode.
  4. Look for options like Turn off hotspot automatically or Limit background activity and disable them.

After changing this, restart the hotspot and reconnect devices one by one.

Reset the Hotspot Network Configuration

IP conflicts often appear when multiple devices request addresses simultaneously. A quick hotspot reset forces the phone to rebuild its internal network.

  1. Turn off the hotspot.
  2. Enable Airplane Mode for about 30 seconds.
  3. Turn Airplane Mode off.
  4. Rename the hotspot and set a new password.
  5. Reconnect devices using the new credentials.

Changing the name prevents devices from reusing old cached network settings.

Switch Hotspot Band (2.4 GHz vs 5 GHz)

Some devices handle shared connections poorly on certain wireless bands. A mismatch can cause disconnects when multiple clients join.

  1. Open Hotspot settings.
  2. Find AP Band or Hotspot Frequency.
  3. Switch from 5 GHz to 2.4 GHz, or vice versa.

2.4 GHz is slower but more stable for multiple devices, especially older laptops or smart TVs.

Check Carrier or Data Limits

Some carriers silently restrict hotspot sessions after detecting multiple connected devices. The phone may disconnect to enforce bandwidth policies.

Try connecting two devices while monitoring mobile data usage. If the hotspot consistently drops after a few seconds, test with another SIM card or check your carrier’s tethering allowance.

Update System Software

Hotspot instability is frequently tied to firmware bugs. Updates often include modem or network stack fixes.

  1. Go to Settings → System → Software Update.
  2. Install any available updates.
  3. Restart the phone before testing again.

Optional Alternative: Limit Connected Devices

If disconnects continue, set a maximum connection limit.

  1. Open hotspot settings.
  2. Find Connected devices limit.
  3. Set it to two or three devices instead of unlimited.

This reduces connection renegotiation that can trigger resets on some phones.

Once the hotspot remains stable after adding another device, the issue is typically resolved. If drops still occur, the limitation is likely hardware or carrier-side rather than a configuration problem.
