Raymarine LIGHTHOUSE SPORT 3.18 Operation Instructions Manual page 140

Possible cause
Interference caused by other
devices that use the 2.4 GHz
frequency. See following list of
some common devices that use the
2.4 GHz frequency:
• Microwave ovens
• Fluorescent lighting
• Cordless phones / baby monitors
• Motion sensors
Interference caused by electrical
and electronic devices and
associated cabling could generate
an electromagnetic field which may
interfere with the Wi-Fi signal.

Possible solutions
Temporarily switch off each device
in turn until you have identified the
device causing the interference,
then remove or reposition the
offending device(s).
Temporarily switch off each item in
turn until you have identified the
device causing the interference,
then remove or reposition the
offending device(s).
Connection extremely slow and / or keeps dropping out
Possible cause
Wi-Fi performance degrades over
distance, so products farther
away will receive less network
bandwidth. Products installed close
to their maximum Wi-Fi range will
experience slow connection speeds,
signal dropouts or not being able to
connect at all.
Interference being caused by other
Wi-Fi enabled or older Bluetooth
enabled devices (Bluetooth and
Wi-Fi both operate in the 2.4
GHz frequency range, some older
Bluetooth devices may interfere with
Wi-Fi signals.)
Interference from devices on other
vessels. When in close proximity to
other vessels (for example, when
moored up in a marina), many other
Wi-Fi signals may be present.
Network connection established but no data
Possible cause
No internet connection to router.
Possible solutions
Move display closer to router.
1. If possible, change the Wi-Fi
Channel that your router is using
and retry the connection. You
can use free Wi-Fi analyzer
apps on a smart device to help
you choose a better channel
(channel with least traffic)..
2. Temporarily switch off each
item in turn until you have
identified the device causing
the interference, then remove
or reposition the offending
device(s).
1. If possible, change the Wi-Fi
Channel that your router is using
and retry the connection. You
can use free Wi-Fi analyzer
apps on a smart device to help
you choose a better channel
(channel with least traffic).
2. If possible, move your vessel to
a location with less Wi-Fi traffic.
Possible solutions
Ensure that your display is
connected to a network with an
internet connection.
