Model-specific
What is true of this model and not of its siblings
- Sleep mode
- The connection dropped as the console slept.
- Reconnect
- A restart and test usually fixes it.
- Sleep and the network
- When the console enters sleep mode, the wireless connection can be dropped to save power, and if you were in the middle of something online, the error reports that the connection was lost because of sleep. The console is not faulty; it behaved as designed.
- Keeping it awake
- Raise the auto-sleep time in System Settings, Sleep Mode, if you do long online sessions, or keep the console on charge. Some routers also drop idle devices, so check the router's power-saving options.
- Reconnecting
- Wake the console, restart it if it will not reconnect, create a new internet connection and run the test. Online sessions will need to be started again.
- Sleep settings worth changing
- In System Settings, Sleep Mode, you can lengthen auto-sleep while playing and while watching media, and decide what the console does while asleep, such as downloading updates. Players who leave a session running for hours should lengthen the time or keep the console on its charger, because a sleeping console drops its Wi-Fi link.
- Router behavior
- Many routers disconnect devices that have been idle for a time. If the console always loses its connection after the same stretch of sleep, the router's idle timeout is the likely cause, and reserving an address for the console or turning off the router's power-saving options helps.
- Telling sleep from a real drop
- If the console had been idle or the screen was off when the message came, sleep was the cause and nothing is broken. If you were actively playing and the message came, the cause is a real drop, and the notes on signal and routers apply instead.
- If it keeps happening
- Games with long sessions, such as online lobbies left open, trigger this more than short ones. Adjust the sleep time for those, and take the console off sleep mode while you are away from it for a while, so you do not return to a dropped session.
