1. Physical checks
Power supply
The most important step is to check the power supply, sometimes the most simple thing is the biggest barrier. The first thing should always be, checking the power supply to the router and/or on the boat. The device normal working state should be indicated with green power LED on (located under power connector).
Antenna
The antenna should be set in the right way (pay extra attention to male/female inputs, antennas should NOT be too tightened, but also not too loosen - balance is the key!). Loose or damaged antennas are presented with no or weak signal strength, indicated by low or none LED signal lamps.
Water damage
The water damage is visible as a small white, chalk-like, stain on the device- right next to the input. It is NOT covered by warranty, so carefully place the device in a safe and dry place. Water damage has various symptoms, one of the most critical symptoms manifests as "device does not power on - power LED does not turn on".
2. Unplug your Sentinel WiFi from its power source (power cycle)
If you experience problems where a router has been just activated, or signal strength LED lamps are blinking, or poor WiFi data connection is observed. Power cycle should be performed. You should unplug the router from power supply and wait about 5 minutes before plugging in again. After power reconnect, wait for 2–3 minutes while the Sentinel WiFi connects to the network. Check the state of the router
3. Check the flashing intervals of lights on your Sentinel WiFi
Always asses the working state with state of LED lamps. You can use the link for detailed instructions on proper flashing intervals of lights on your Sentinel WiFi→ http://bit.ly/routerlights. Reporting the state is mandatory when reporting an issue.
4. Poor signal strength - no data connection
Following the link - https://sentinel.hr/wifi/#faq-wifi-support-3ae14d8a265 will reveal the map of problematic areas in Mediterranean sea. Areas with no coverage are marked in RED and areas with low coverage are marked in PURPLE. This will help you, when customers report poor or no data connection. Note that this information is subject to change, given the installation of new cell towers. During the peak season (July - August) the quality of coverage can vary drastically during the day. You can zoom in on the map for a more detailed investigation.
