Possible Cause
Wrong IP configuration
Wrong Ethernet port
operation mode
ARP table in the PC
contains a wrong MAC
address for the
192.168.254.251 IP

Corrective Action
Make sure that the PC is on the same subnet as the
unit. The unit's IP address for management
purposes is 192.168.254.251, and the subnet mask
is 255.255.255.0.
Make sure that the speed and duplex settings in the
PC match the configuration in the unit. The default
operation mode is Auto Negotiation, and supported
speeds are 10/100 Mbps, Full or Half Duplex.
Perform arpV-d at the DOS command prompt to
clear the ARP table, and retry the Telnet command
to the unit.
Reset the CPE to clear the table and retry the Telnet
command to the unit.
Verify proper configuration of Frequency Scanning
parameters.
Verify proper configuration of BS ID parameters.
If proper configuration parameters are not known,
press the RESET button for more than 5 seconds to
activate the factory default configuration
