See the wireless events generated by your access points.

Go to My Products > Wireless > Diagnostics > Events and review your events.

The events list shows you the severity, date and time the event occurred, and the type of event.

Sophos Central categorizes events as one of the following severity levels:

  • High High severity.
  • Medium Medium severity.
  • Low Low severity.


Access points generate high severity events when the connected device load on access points is high or action is required.

Events Description
Access point has bad health. Number of connected devices is high. Reduce the number of connected devices.
Security Heartbeat is enabled in Sophos Firewall and Sophos Central Wireless. Use either Sophos Firewall or Sophos Central to turn on Security Heartbeat.
Ethernet LAN speed is low. Wireless performance may be affected by slow LAN speeds.
DNS gateway is unreachable. The access point can't connect to the DNS server.
Access Point gateway not reachable The access point can't connect to its configured gateway IP address.


Access points generate medium severity events when configuration is needed, they're offline, or they have latency issues.
