All of your Internet and network connection details are displayed on the Device Info page. The firmware version is also displayed here.
Note: Some browsers have limitations that make it impossible to update the WAN status display when the status changes. Some browsers require that you refresh the display to obtain updated status. Some browsers report an error condition when trying to obtain WAN status.
Depending on the type of WAN connection, you can take one of the following sets of actions:
- DHCP Connection
- Clicking the button unassigns the router's IP address. The router will not respond to IP messages from the WAN side until you click the button or power-up the router again. Clicking the button causes the router to request a new IP address from the ISP's server.
- PPPoE, PPTP, L2TP Connection
- Depending on whether the WAN connection is currently established, you can click either the to attempt to establish the WAN connection or the to break the WAN connection.
- Static IP
- Static IP mode is always on, so no action buttons are avaliable.
- Wireless LAN
- This area of the screen reflects configuration settings from the Setup → Wireless Settings page. The MAC Address is the factory-assigned identifier of the wireless card.
- LAN Computers
- This area of the screen continually updates to show all DHCP enabled computers and devices connected to the LAN side of your router. The detection "range" is limited to the address range as configured in DHCP Server. Computers that have an address outside of this range will not show. If the DHCP Client (i.e. a computer configured to "Automatically obtain an address") supplies a Host Name then that will also be shown. Any computer or device that has a static IP address that lies within the detection "range" may show, however its host name will not.
- IGMP Multicast memberships
- If IGMP is enabled, this area of the screen show all multicast groups of which any LAN devices are members.
The router automatically logs (records) events of possible interest in its internal memory. If there is not enough internal memory for all events, logs of older events are deleted, but logs of the latest events are retained. The Logs option allows you to view the router logs. You can define what types of events you want to view and the level of events to view. This router also has internal Syslog Server support so you can send the log files to a computer on your network that is running a Syslog utility.
- What to View
- Select the kinds of events that you want to view.
- Firewall and Security
- Router Status
- View Levels
- Select the level of events that you want to view.
- Apply Log Settings Now
- Click this button after changing Log Options to make them effective and permanent.
- Clicking this button refreshes the display of log entries. There may be new events since the last time you accessed the log.
- Clicking this button erases all log entries.
- Email Now
- If you provided email information with the Tools -> Email screen, clicking the button sends the router log to the configured email address.
- Save Log
- Select this option to save the router log to a file on you computer.
The Statistics page displays all of the LAN, WAN, and Wireless packet transmit and receive statistics.
- The number of packets sent from the router.
- The number of packets received by the router.
- TX Packets Dropped
- The number of packets that were dropped while being sent, due to errors, collisions, or router resource limitations.
- RX Packets Dropped
- The number of packets that were dropped while being received, due to errors, collisions, or router resource limitations.
- The number of packets that were dropped due to Ethernet collisions (two or more devices attempting to use an Ethernet circuit at the same time).
- The number of transmission failures that cause loss of a packet. A noisy radio-frequency environment can cause a high error rate on the wireless LAN.
The Active Sessions page displays full details of active sessions through your router. A session is a conversation between a progam or application on a LAN-side computer and a program or application on a WAN-side computer.
- The IP address and port number of the LAN-side application.
- The port number of the LAN-side application as viewed by the WAN-side application.
- The IP address and port number of the WAN-side application.
- The communications protocol used for the conversation.
- State for sessions that use the TCP protocol.
- NO: None -- This entry is used as a placeholder for a future connection that may occur.
- SS: SYN Sent -- One of the systems is attempting to start a connection.
- EST: Established -- the connection is passing data.
- FW: FIN Wait -- The client system has requested that the connection be stopped.
- CW: Close Wait -- the server system has requested that the connection be stopped.
- TW: Time Wait -- Waiting for a short time while a connection that was in FIN Wait is fully closed.
- LA: Last ACK -- Waiting for a short time while a connection that was in Close Wait is fully closed.
- CL: Closed -- The connection is no longer active but the session is being tracked in case there are any retransmitted packets still pending.
- The direction of initiation of the conversation:
- Initiated from LAN to WAN.
- Initiated from WAN to LAN.
- The preference given to outbound packets of this conversation by the QoS Engine logic. Smaller numbers represent higher priority.
- Time Out
- The number of seconds of idle time until the router considers the session terminated. The initial value of Time Out depends on the type and state of the connection.
- 300 seconds
- UDP connections.
- 240 seconds
- Reset or closed TCP connections. The connection does not close instantly so that lingering packets can pass or the connection can be re-established.
- 7800 seconds
- Established TCP connections.
The wireless section allows you to view the wireless clients that are connected to your wireless router.
- MAC Address
- The Ethernet ID (MAC address) of the wireless client.
- IP Address
- The LAN-side IP address of the client.
- The transmission standard being used by the client. Values are 11a, 11b, or 11g for 802.11a, 802.11b, or 802.11g respectively.
- The actual transmission rate of the client in megabits per second.
- This is a relative measure of signal quality. The value is expressed as a percentage of theoretical best quality. Signal quality can be reduced by distance, by interference from other radio-frequency sources (such as cordless telephones or neighboring wireless networks), and by obstacles between the router and the wireless device.
