1. Verify that other devices on your network can connect to the internet.
2. (Xbox and PlayStation only) Make sure that your console is connected to your router directly using an Ethernet cable. Wireless signals (Wi-Fi) can often experience interference and the signal quality can drop over time.
3. Perform a network connection test for your console. For reference, here is a list of platform-specific troubleshooting guides:
- Xbox 360: https://support.xbox.com/help/hardware-network/connect-network/xbox-360-network-connection
- Xbox One: https://support.xbox.com/help/hardware-network/connect-network/xbox-one-network-connection
- Xbox Series X|S: https://support.xbox.com/help/hardware-network/connect-network/xbox-one-network-connection-errors
4. Disconnect your router and modem for 60 seconds from the power outlet, then reconnect them to the outlet.
NOTE: It may take a few minutes for your internet connection to be restored while the modem fetches all of its information from your Internet Service Provider (ISP).
5. Your connection strength can be affected by how busy your network is. If you’re on a college campus or a home network that makes heavy usage of streaming services (Netflix, Twitch, etc.), downloading large files over the internet or playing other online video games, then you are more at risk of experiencing disconnection issues. If that’s the case, try playing online when fewer people are using the internet.
6. Certain features on your router can also impact performances. Here are a few that you can try disabling (or enabling):
- NOTE: If modifying these settings makes no difference on your game performance, then it is recommended to return them to their default settings.
- Dynamic Packet Filtering / Stateful Inspection
- Quality of Service (QoS)
- UPnP (Universal Plug and Play)
- Some routers have specialized settings for gaming. You can look at your router’s manual for more information.
7. (Xbox and PlayStation only) You can also try connecting your console directly to the modem instead of the router. Here’s how:
