If you are experiencing high latency, frequent disconnections, or general connectivity issues follow the steps below to help identify and resolve the problem.

1. Identify your issue

You may be affected if you notice one or more of the following:

  • High ping or delayed actions
  • Rubber‑banding or stuttering during matches
  • Frequent disconnections
  • Long matchmaking times
  • Unable to connect to the game

2. Check if the issue is temporary

Connection issues can sometimes be caused by temporary server or network instability.

Try this first:

  • Fully close and restart the game.
  • Wait a few minutes and try connecting again.

If many players are affected at the same time, the issue may not be on your side.

3. Test your network connection (important)

Rainbow Six Mobile requires a stable, low‑latency connection, not just high download speed.

Try switching networks:

  • If you are on Wi‑Fi, switch to mobile data and test again.
  • If you are on mobile data, switch to Wi‑Fi if possible.

If using Wi‑Fi:

  • Move closer to your router.
  • Avoid public or shared networks (cafés, schools, hotels).

If using mobile data:

  • Ensure you have a strong signal.
  • Avoid playing while moving (car, train, bus).

4. Disable network‑restricting features on your device

Some device settings can interfere with real‑time online games.

On Android:

  • Disable Battery Saver / Power Saving Mode.
  • Allow unrestricted data usage for Rainbow Six Mobile.
  • Disable VPNs, firewalls, or network‑optimizer apps.

On iOS:

  • Disable Low Power Mode.
  • Ensure Cellular Data is enabled for Rainbow Six Mobile.
  • Temporarily disable VPNs or iCloud Private Relay.

5. Reduce background activity

Other apps can affect network stability.

  • Close background apps (especially streaming, downloads, or video calls).
  • Restart your device before playing.
  • Make sure your device has enough free storage space.

6. When the issue may not be on your side

The problem is likely server‑side or ISP‑related if:

  • It happens only during peak hours.
  • Other players are affected at the same time.
  • It persists across different networks and devices.

In this case, waiting and trying again later may be the best solution.
