Why is the System Status screen on my Trio IHD showing a WiFi error?

When the System Status screen shows the WiFi symbol in red or amber, then this means one of the following:

• The monitor is out of range of the WiFi network or it is not available – try moving closer to the access point or router
• The security details for the configured WiFi network have changed since they were setup
• The monitor’s details have been actively blocked by the WiFi network
• The monitor is running on batteries – the WiFi module does not function when running on batteries
