Connection extremely slow and or keeps
dropping out
Possible cause

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 drop outs 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
Connected to the wrong
network.
