DHCP client will be launched by default. If the address is not obtained via DHCP, the device will have the default IP address — 192.168.1.10, and the following netmask — 255.255.255.0.

Delivery package

The delivery package includes:

• WEP-3ax wireless access point;
• Mounting kit;
• User manual on a CD (optionally);
• Technical passport.

Rules and recommendations for device installation

This section defines safety rules, installation recommendations, setup procedure and the device starting procedure.

Safety rules

1. Do not install the device close to heat sources or at rooms with temperature below 5 °C or higher 40 °C.
2. Do not use the device in places with high humidity. Do not expose the device to smoke, dust, water, mechanical vibrations or shocks.
3. Do not open the device case. There are no user serviceable parts inside.

Installation recommendations

1. Recommended mounting position: horizontal, on the ceiling.
2. Before installing the device and turning it on, check the device for visible mechanical defects. If defects are observed, stop the device installation, fill in the corresponding act and contact the supplier.
3. If the device has been exposed to the cold for a long period of time, let it warm up at room temperature for two hours before starting work. If the device has been exposed to high humidity for a long period of time, let it stay under normal conditions for at least 12 hours before turning it on.
4. During the device installation, follow these rules to ensure the best Wi-Fi coverage:
   1. Install the device at the center of a wireless network;
   2. Minimize the number of obstacles (walls, ceilings, furniture and etc.) between access point and other wireless network devices;
   3. Do not install the device near (about 2 m) electrical and radio devices;
   4. It is not recommended to use radiophone and other equipment operating at the frequency of 2.4 GHz, 5 GHz in Wi-Fi effective radius;
   5. Obstacles in the form of glass/metal constructions, brick/concrete walls, water cans and mirrors can significantly reduce Wi-Fi action radius. It is not recommended to place the device inside a false ceiling as metal frame causes multipath signal propagation and signal attenuation.
5. When installing several access points, cell action radius should overlap with action radius of a neighboring cell at the level from -65 to -70 dBm. It is allowed to reduce the signal level to -75 dBm at cell boundaries, if it is not intended to use VoIP, video streaming and other sensitive to losses traffic in wireless network.

Calculating the number of required access points

To calculate the required number of access points, evaluate the required coverage zone. For a more accurate assessment, it is necessary to make a radio examination of the room. Approximate coverage radius of confident reception of WEP-3ax access points when mounted on the ceiling in a typical office space: 2.4 GHz — 40–50 m, 5 GHz — 20–30 m. If there are no obstacles, the coverage area is up to 100 m for the 2.4 GHz band and up to 60 m for the 5 GHz band. 
Table 4 describes approximate attenuation values.

...

Channel selection for neighboring access points

It is recommended to set non-overlapping channels to avoid interchannel interference among neighboring access points.

...
