Please make sure that both VHF and GPS antennas and their cables are working

Return the unit to your dealer/service partner for technical check.
Why is the Wi-Fi signal weak and how can I improve it?
The router is too far from the client devices. To improve the Wi-Fi signal strength
reallocated the device to a more central location.
There might be intervening barriers (e.g. a large expanse of metal) that are
blocking the Wi-Fi signals. Relocated the device to the center of the area where
the client devices are placed, or to a position where the router and the devices ae
are within a visible distance without interfering barrier.
Nearby devices (e.g. microwaves/wireless phones) using the same frequency band
may interfere with the routers 2.4GHz Wi-Fi transmission. To improve the Wi-Fi
signal strength, try to avoid channel overlapping by reassigning their operation
channels to channels 1, 6 or 11.
If you still encounter difficulties to set up or operate WideLink B600 correctly, please
email to service@alltekmarine.com for further instructions.
