Before You Begin
Basic Requirements
Quick Setup
Before You Begin
Please read this guide carefully before installing and using the range extender.
The operating range of your wireless network may vary significantly depending
on the physical position of the wireless devices. Obstructions, such as metal
appliances and walls, may weaken signals by getting in the way of your
network’s radio waves.
In order to optimize the performance of the extender, please follow the
instructions below (please make sure the extender is always within the wireless
coverage of the wireless router).
●Half-wayBetween- Generally, the ideal location for the range extender is
half-way between the wireless router and the wireless client. If the
wireless signal is not satisfactory, you may place the extender closer to
the wireless router.
●Less Obstructions - Limitobstructions between the extender and wireless
router. It’s better to locate the extender in a spacious place, such as near
the corridors.
●No Interference - Choose a location away from Bluetooth devices and
other household electronics, such as cordless phone, microwave, and baby
monitor, etc., to minimize signal interference.

DHCP Server
DHCP stands for Dynamic Host Configuration Protocol. The DHCP Server will
automatically assign dynamic IP addresses to the devices on the network. This
protocol simplifies network management and allows new wireless devices to be
set to IP addresses automatically.
To use the DHCP server function of the device, you should
configure all computers in the LAN as "Obtain an IP Address
automatically" mode.
