Disclaimer
Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Range, coverage, and maximum quantity of connected devices are based on test results under normal usage conditions. Actual wireless data throughput, wireless coverage, and quantity of connected devices are not guaranteed and will vary as a result of 1) environmental factors, including building materials, physical objects, and obstacles, 2) network conditions, including local interference, volume and density of traffic, product location, network complexity, and network overhead, and 3) client limitations, including rated performance, location, connection quality, and client condition.
*Use of MU-MIMO requires clients to also support MU-MIMO.
Power consumption in networked standby: 6.1 W
Power consumption in networked standby when all wired network ports are connected and all wireless network ports are activated: 6.9 W.
The default period of time after which the power management function switches the equipment automatically into a condition providing networked standby: 20 minutes
How to activate and deactivate wireless network: Enter the webpage of product through wired connecting. The wireless function can be turn on/off via ‘Advanced ->Wireless -> Wireless Settings -> Enable Wireless Radio’.

2. Connect the Hardware
2.1 Position Your Router
-
With the modem router, you can access your network from anywhere within the wireless network coverage. However, the wireless signal strength and coverage varies depending on the environment your modem router is in. Obstacles may limit the range of the wireless signal, for example, concrete structures, thick walls.
-
For best Wi-Fi performance, and to keep your network secure:
-
Do not locate the modem router in a place where it will be exposed to moisture or excessive heat.
-
Keep the product away from strong electromagnetic radiation and devices that emit electromagnetic waves.
-
Place the modem router in a location where it can be connected to the various devices as well as to a power source.
-
Make sure the cables and power cord are safely placed out of the way so they do not create a tripping hazard.
Generally, the router is placed on a horizontal surface, such as on a shelf or desktop. The device also can be mounted on the wall as shown in the following figure.

Note: The diameter of the screw, 6mm<D<10mm, and the distance of two screws is 161.85mm. The screw that project from the wall need around 4mm based, and the length of the screw need to be at least 20mm to withstand the weight of the product.
2.2 Connect Your Router
Follow the steps below to connect your modem router.
1. Connect the DSL line and power adapter. The electrical outlet shall be installed near the device and shall be easily accessible.
2. Connect your computer to the modem router.
Method 1: Wired
Connect your computer’s Ethernet port to the LAN port on the modem router via the Ethernet cable.
Method 2: Wirelessly
Use the default SSID (Wireless Network Name) and Wireless Password printed on the product label of the modem router to connect wirelessly.
Method 3: Use the WPS button
Wireless devices that support WPS, including Android phones, tablets, most USB network cards, can be connected to your router through this method. (WPS is not supported by iOS devices.)
Note: The WPS function cannot be configured if the wireless function of the router is disabled. Also, the WPS function will be disabled if your wireless encryption is WEP. Please make sure the wireless function is enabled and is configured with the appropriate encryption before configuring the WPS.
1) Tap the WPS icon on the device’s screen.
2) Immediately press the WPS button on your modem router.
3) The WPS LED flashes for about two minutes during the WPS process.
When the WPS LED stabilizes and remains on, the client device has successfully connected to the modem router.
