Gateway IP Address: 169.254.128.1
3. Change the IP address and other network values using the following CLI commands (use your own IP address and
Subnet mask).
System Name> enable
System Name# configure
System Name(config)#network
System Name(config-net)# ip
System Name(config-net-ip)# ethernet-ip-table
System Name(config-net-ip-etherip)# rowedit 1 ipaddress <ipaddress>
System Name(config-net-ip-etherip)# rowedit 1 mask <subnet mask>
System Name(config-net-ip-etherip)# rowedit 1 address-type <Address Type>
System Name(config-net-ip)# default-gateway <IP Gateway>
System Name(config-net-ip-etherip)#exit
System Name(config-net-ip)#exit
System Name(config-net)#exit
System Name(config)# commit 1
System Name(config)# reboot 1
4. After the device reboots, verify the new IP address by reconnecting to the CLI. Alternatively, you can ping the device
from a network computer to confirm that the new IP address has taken effect.
When a proper IP address is set, use HTTP interface or Telnet to configure the rest of the operating parameters of the
device.

8.10 Spectrum Analyzer
The ultimate way to discover whether there is a source of interference is to use a Spectrum Analyzer. Usually, the antenna is
connected to the analyzer when measuring. By turning the antenna 360°, one can check the direction of the interference.
The analyzer will also display the frequencies and the level of signal is detected. Proxim recommends performing the test at
various locations to find the most ideal location for the equipment.

8.10.1 Avoiding Interference
When a source of interference is identified and when the level and frequencies are known, the next step is to avoid the
interference. Some of the following actions can be tried:
interference. Some of the following actions can be tried:
•
Change the channel to a frequency that has no or least interference.
•
Try changing the antenna polarization.
•
A small beam antenna looks only in one particular direction. Because of the higher gain of such an antenna, lowering
the output power or adding extra attenuation might be required to stay legal. This solution cannot help when the
source of interference is right behind the remote site.

source of interference is right behind the remote site.
•
Adjusting the antenna angle/height can help to reduce the interference.
Move the antennas to a different location on the premises. This causes the devices to look from a different angle, causing a
different pattern in the reception of the signals. Use obstructions such as buildings, when possible, to shield from the
interference.

8.10.2 Conclusion
A spectrum analyzer can be a great help to identify whether interference might be causing link problems on the device.
Before checking for interference, the link should be verified by testing in an isolated environment, to make sure that the
hardware works and your configurations are correct. The path analysis, cabling and antennas should be checked as well.
