The router sent a TCP reset packet when a host was
under a SYN flood attack (the TCP incomplete count is per
destination host.)
The router sent a TCP reset packet when the number of
TCP incomplete connections exceeded the user config ured
threshold. (the TCP incomplete count is per destination

The router sent a TCP reset packet when a TCP
connection state was out of order.Note: The firewall
refers to RFC793 Figure 6 to check the TCP state.
The router sent a TCP reset packet when a dynamic
firewall session timed out.
The default timeout values are as follows:
ICMP idle timeout: 3 minutes
UDP idle timeout: 3 minutes
Chapter 18 The Logs Screens
TCP connection (three way handshaking) timeout: 270

TCP FIN-wait timeout: 2 MSL (Maximum Segment
Lifetime set in the TCP header).
TCP idle (established) timeout (s): 150 minutes
TCP reset timeout: 10 seconds

RST
The router sent a TCP reset packet when the number of
incomplete connections (TCP and UDP) exceeded the
user-configured threshold. (Incomplete count is for all
TCP and UDP connections through the firewall.)Note:
When the number of incomplete connections (TCP + UDP)
> “Maximum Incomplete High” , the router sends TC P RST
packets for TCP connections and destroys TOS (firewall
dynamic sessions) until incomplete connections <
“Maximum Incomplete Low”.
The router sends a TCP RST packet and generates this log
if you turn on the firewall TCP reset mechanism (via CI
command:
sys firewall tcprst).

identifies it across the network.
WiMAX State This field displays the status of the WiMAX Modem’s current connection.
• INIT : the WiMAX Mod e m is starting up .
• DL_SYN: The WiMAX Modem is unable to connect to a base station.
• RANGING: the WiMAX Modem and the base station are transmitting
and receiving information about the distance between them.
Ranging allows the WiMAX Modem to use a lower transmission
power level when communicating with a nearby base station, and a
higher transmission power level when communicating with a distant
base station.
• CAP_NEGO: the WiMAX Modem and the base station are
exchanging information about their capabilities.
• AUTH: the WiMAX Modem and the base station are exchanging
security information.
• REGIST: the WiMAX Modem is registering with a RADIUS server.

the base station. Traffic can now flow between the WiMAX Modem
and the base station.
• IDLE: the WiMAX Modem is in power saving mode, but can connect
when a base station alerts it that there is traffic waiting.
Bandwidth This field shows the size of the bandwidth step the WiMAX Modem uses
to connect to a base station in megahertz (MHz).
CINR mean This field shows the average Carrier to Interference plus Noise Ratio of
the current connection. This value is an indication of over all radio signal
quality. A higher value indicates a higher signal quality, and a lower
value indicates a lower signal quality.
CINR deviation This field shows the amount of change in the CINR level. This value is
an indication of radio signal stability. A lower number indicates a more
stable signal, and a higher number indicates a less stable signal.
RSSI This field shows the Received Signal Strength Indication. This value is a
measurement of overall radio signal strength. A higher RSSI level
indicates a stronger signal, and a lower RSSI level indicates a weaker

Troubleshooting
This chapter offers some suggestions to solve problems you might encounter. The
potential problems are divided into the following categories:
• Power, Hardware Connections, and LEDs
• WiMAX Modem Access and Login
• Internet Access
• Phone Calls and VoIP
• Reset the WiMAX Modem to Its Factory Defaults
20.1 Power, Hardware Connections, and LEDs
The WiMAX Modem does not turn on. None of the LEDs turn on.
1 Make sure you are using the power adapter or cord included with the WiMAX
Modem.
2 Make sure the power adapter or cord is connected to the Wi MA X Mod e m an d
plugged in to an appropriate power source. Make s ure the power source is turned
on.
3 Disconnect and re-connect the power adapter or cord to the WiMAX Modem.
4 If the problem continues, contact the vendor.
One of the LEDs does not behave as expected.
1 Make sure you understand the normal behavior of the LED. See Section 1.2.1 on
User’s Guide
page 34 for more information.

Chapter 20 Troubleshooting
2 Check the hardware connections. See the Quick Start Guide.
3 Inspect your cables for damage. Contact the vendor to replace any damaged
cables.
4 Disconnect and re-connect the power adapter to the WiMAX Modem.
5 If the problem continues, contact the vendor.
20.2 WiMAX Modem Access and Login
I forgot the IP address for the WiMAX Modem.
1 The default IP address is http://192.168.1.1.
2 If you changed the IP address and have forgotten it, you might get the IP address
of the WiMAX Modem by looking up the IP address of the default gateway for your
computer. To do this in most Windows computers, click Start > Run, enter cmd,
and then enter ipconfig. The IP address of the Default Gateway might be the IP
address of the WiMAX Modem (it depends on the network), so enter this IP
address in your Internet browser.
3 If this does not work, you have to reset the WiMAX Modem to its factory defaults.
See Section 20.1 on page 229.
I forgot the password.
1 The default password is 1234.
2 If this does not work, you have to reset the WiMAX Modem to its factory defaults.
See Section 9.5 on page 106.
I cannot see or access the Login screen in the web configurator.
