Step-by-Step Solution
Check Your Internet
Verify your home internet is working on another device. If WiFi is down, No Link is expected. Fix your internet connection first.
Power Cycle Base Station
Unplug base station power adapter. Wait 30 seconds. Plug back in. Wait 2-3 minutes for full boot and reconnection attempt.

If you changed WiFi password or router, base station needs reconnection. On keypad, go to Menu > WiFi to reconnect with current password.
Check SimpliSafe Status
Visit status.simplisafe.com or SimpliSafe Twitter for any service outages. If servers are down, wait for SimpliSafe to restore service.
Verify Cellular Backup
Gen 3 base station has cellular backup. If WiFi fails but cellular works, you should still have monitoring. No Link on both means connection issue.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
No Link does not disable local alarm. Your system still sounds alarm locally, but professional monitoring cannot be notified.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
