## Enclosure

The waterproof enclosure is diecast from anti-corrosion ADC12 aluminum by 100-ton pressure. It's passed a bundle of rugged tests for long-period outdoor operation, such as the Salt Spray Test, Leakage Test, IP67 Waterproof Test, etc.

The electronic design abides by industrial outdoor standards with surge protection and withstands extreme temperatures.

**Open the Enclosure**\
Use the hexagon head on the T-wrench to lose bolts in the anti-clockwise direction.

**Seal the Enclosure**\
Close the lid & press with your hand. Ensure no gap after closing. Use the T-wrench to tighten all bolts in the clockwise direction.

## Indicators

There are six working indicators on the motherboard of the WiFi extender.

The image below shows Wi-Fi, System, Internet, Power, WAN, and LAN indicators on the bottom side of the motherboard. Check the chart below about the indicator status and related performance.

If it lit solid green, then the router has booted successfully.</td></tr><tr><td></td><td>Flash</td><td>The router system is booting up. The system indicator flashes while resetting or flashing the firmware.</td></tr><tr><td></td><td>Off</td><td>Short of power. Check the PoE or DC power connection.</td></tr><tr><td><strong>Wi-Fi</strong></td><td>Green</td><td>Wi-Fi hotspot is enabled. You can find and connect to the Wi-Fi hotspot if the light is green.</td></tr><tr><td></td><td>Flash</td><td>If you are connected to the Wi-Fi hotspot, it will flash green to indicate data going to and from the router. If the router is connected to another Wi-Fi hotspot (Wi-Fi relay), it will also flash because it has the data flow.</td></tr><tr><td></td><td>Off</td><td>If it's off, your router no longer sends a Wi-Fi signal. You can log in to the router admin and turn on the Wi-Fi hotspot.</td></tr><tr><td><strong>Internet</strong></td><td>Green</td><td>Indicates the extender has a workable internet connection.</td></tr><tr><td></td><td>Flash</td><td>Means internet is activated with data flow.</td></tr><tr><td></td><td>Off</td><td>No workable internet.</td></tr><tr><td>WAN LAN</td><td>Green</td><td>WAN (or LAN) connection is activated.</td></tr><tr><td></td><td>Flash</td><td>WAN (or LAN) interface has data flow.</td></tr><tr><td></td><td>Off</td><td>No activated connection on WAN (LAN) interface.</td></tr></tbody></table>
