User name and password are required for access to management functions. There are two levels or privileges:
administrators’ privilege and normal users’ privileges.
Administrator’s privilege is designed for service providers to provision a CPE device before selling or
leasing out to end users. By supplying administrator’s user name and password, a technician has access
to all configurations of a CPE device. Default user name for administrator’s privileges is “admin”.
Default password is “admin”.
Users’ privilege is provisioned for end users to make limited changes of configurations for a CPE
device. Most of other configurations are not visible when accessed with normal user’s privileges.
Default user name and password for user is “user”.
4.1 Managing CPE via Telnet Access
To Telnet into CPE device, the IP address of its WAN interface or LAN interface must be known:
Default IP address for the LAN interface is 192.168.0.1, unless the configuration has been modified.
The IP address for WAN interface is usually acquired from service provider’s network after CPE
connects to the WiMAX network.
4.1.1 Telnet Access to CPE from LAN Segment
The user may Telnet into the CPE by specifying the IP address of CPE LAN interface. The default IP Address of
the CPE LAN interface is 192.168.0.1.
The CPE acts as a DHCP server for hosts in LAN segment by default, unless this feature is disabled. Control
Station may dynamically acquires an IP address from CPE built-in DHCP server.
After IP connectivity is established between the Control Station and CPE, the user may Telnet into the CPE.
4.1.2 Telnet Access from Wireless Interface Segment
The user may also Telnet into the CPE by specifying the wireless IP address of the CPE device. Access from
Wireless interface is very helpful for remote troubleshooting.
The wireless IP address is usually acquired via DHCP once the CPE is connected into the service provider’s
network. To find out the wireless IP, Support technician may seek end user’s help to find out IP address of the
wireless interface of CPE located in customer premise. The easiest way for end users is to follow the
instructions outlined in Section 4.2.1. End users may be given a user name and password with lower privilege to
access limited information stored in the CPE.
CAUTION Telnet from remote location is not recommended as user name and password are
sent in clear text. Malicious users may sniff IP packets and find administrator’s
credentials easily.
4.2 Managing CPE via Web Browser
It is a preferred way to manage the CPE using a Web browser from a local or remote host, for example, Internet
Explorer in Windows operation systems.
The reader has the option to access the CPE using the LAN interface or wireless IP if it is known.
The default IP address for the LAN interface is 192.168.0.1, unless the configuration has been modified.
The WAN IP is usually acquired from service provider’s network after CPE connects to the network.
4.2.1 Access CPE from LAN Interface
Connect the LAN port of Control Station (a PC) directly to the LAN port of the CPE, or in-indirectly via an
Ethernet hub or switch. By default, the CPE will act as a DHCP server for hosts in the LAN segment unless this
feature is disabled. The Control Station can dynamically acquire an IP address from CPE’s built-in DHCP server.
After IP layer connectivity is established between the Control Station and the CPE, the user may launch a Web
browser and specify http://192.168.0.1 in the address bar. A window will pop up requesting user name and
