3 Installing the MEA Enhanced Wireless Router
3.1 Device Administration: Configuring the EWR Devices
The EWR provides network access to one or more IP devices connected to the Ethernet port of
the EWR. In order for the EWR to provide service to the IP devices, some configuration must
be set up prior to connecting the IP devices.
The EWR serves as a default gateway for the attached IP devices. Because some devices
expect the default gateway to reside on the local subnet, the address that the EWR uses for
gateway service (on the wired interface) must be configurable. Some consideration should be
used in selecting a gateway address for the EWR.
The local default gateway address is used only on the wired interface, and is only visible to the
attached IP devices. It is not advertised to the wireless network, and the network cannot
access the EWR using this gateway address. The EWR has another IP address for the
wireless interface that can be used to access the EWR from the network. Because is gateway
address is limited to the local wired interface, the same address could be used for the gateway
service in several EWR devices. The local gateway should be a part of the overall subnet
chosen for your MEA network.
When selecting IP addresses for the EWR, care must be taken to ensure that the selected IP
addresses do not conflict with any other devices on the mea network.
3.1.1 Accessing the MEA Device Administration Web Pages
To modify the IP configuration for the EWR using the web interface, you must know the IP
address assigned to the wireless interface of the EWR. The IP address can be determined
from MeshManager, or from the DHCP server (once the device is configured for DHCP). The
default IP address for the EWR wireless interface is derived from the transceiver MAC address
(10.xx.yy.1, where the MAC address is 00:05:12:0A:XX:YY), similar to the default IP addresses
described in
Once the IP address is known, you can access the web page of the device. Point your web
browser to the IP address of the EWR. In the examples following, the EWR address is
172.16.1.53, and the web page would be found at
