4.9 System Tools
System Tools option helps you to optimize the configuration of your device. SNMP can help you to
manage the device locally or remotely with specified software. The diagnostic tools (Ping and
Traceroute) allow you to check the connections of your network components. You can Upgrade the
AP to the latest version of firmware as well as Backup or Restore the AP’s configuration files. Ping
Watch Dog can help to continuously monitor a particular connection to a remote host. It’s suggested
that you change the default password to a more secure one because it controls access to the device’s
web-based management page. Besides, you can find out what happened to the system in System
Log. There are nine submenus under the System Tools menu (shown as Figure 4-30): SNMP, Time
Settings, Diagnostic, Ping Watch Dog, Firmware Upgrade, Factory Defaults, Backup & Restore,
Reboot, Password, System Log and Statistics. Selecting any of them will enable you to configure
the corresponding function. The detailed explanations for each submenu are provided below.

 Ping - This diagnostic tool troubleshoots connectivity, reachability, and name resolution to a
given host or gateway by using the Internet Control Message Protocol (ICMP) protocol's
mandatory Echo Request datagram to elicit an ICMP Echo Response from a host or
gateway. You can use ping to test both numeric IP address or domain name. If pinging the IP
address is successful, but pinging the domain name is not, you might have a name resolution
problem. In this case, ensure that the domain name you are specifying can be resolved by
using Domain Name System (DNS) queries.
 Traceroute - This diagnostic tool determines the path taken to a given host by sending
Internet Control Message Protocol (ICMP) Echo Request messages with varying Time to Live
(TTL) values to the destination. Each gateway along the path is required to decrement the
TTL in an IP packet by at least 1 before forwarding it. Effectively, the TTL is a maximum link
counter. When the TTL on a packet reaches 0, the gateway is expected to return an ICMP
Time Exceeded response to your device. Traceroute determines the path by sending the first
Echo Request message with a TTL of 1 and incrementing the TTL by 1 on each subsequent
transmission until the target responds or the maximum number of hops is reached. The
maximum number of hops is 20 by default and can be specified in the field "Traceroute Max
TTL". The path is determined by examining the ICMP Time Exceeded messages returned by
intermediate gateways and the Echo Reply message returned by the destination. However,
some gateways do not return Time Exceeded messages for packets with expired TTL values
and are invisible to the traceroute tool. In this case, a row of asterisks (*) is displayed for that
hop.
IP Address - Enter the IP Address (such as 202.108.22.5) of the PC whose connection you wish to
diagnose.
Ping Count - Specifies the number of Echo Request messages sent. The default is 4.
Ping Packet Size - Specifies the number of data bytes to be sent. The default is 64.
Ping Timeout - Specifies the time to wait for a response in milliseconds. The default is 800.
Traceroute Max TTL - Set the maximum number of hops (max TTL to be reached) in the path to
Survey for the target (destination). The default is 20.
Click the Start button to start the diagnostic procedure.
The Diagnostic Results page displays the result of diagnosis.
If the result is similar to the following screen (Figure 4-34), the connectivity of the Internet is fine.

Appendix E: Glossary
802.11b - The IEEE 802.11b standard specifies a wireless networking at 11 Mbps using directsequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at
2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks.
802.11g – IEEE specification for wireless networking at 54 Mbps using direct-sequence spreadspectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum
at 2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP encryption for security.
Access Point (AP) - A wireless LAN transceiver or "base station" that can connect a wired LAN to
one or many wireless devices. Access points can also bridge to each other.
DNS (Domain Name System) – An Internet Service that translates the names of websites into IP
addresses.
Domain Name - A descriptive name for an address or group of addresses on the Internet.
DoS (Denial of Service) - A hacker attack designed to prevent your computer or network from
operating or communicating.
DSL (Digital Subscriber Line) - A technology that allows data to be sent or received over existing
traditional phone lines.
ISP (Internet Service Provider) - A company that provides access to the Internet.
MTU (Maximum Transmission Unit) - The size in bytes of the largest packet that can be transmitted.
SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a
wireless local area network. For the wireless devices in a network to communicate with each other, all
devices must be configured with the same SSID. This is typically the configuration parameter for a
wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless
network name.
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or 152-bit
shared key algorithm, as described in the IEEE 802.11 standard.
Wi-Fi - A trade name for the IEEE 802.11b wireless networking standard, given by the Wireless
Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group
promoting interoperability among IEEE 802.11b devices.
WLAN (Wireless Local Area Network) - A group of computers and associated devices communicate
with each other wirelessly, which network serving users are limited in a local area.
WPA (Wi-Fi Protected Access) - WPA is a security technology for wireless networks that improves on
the authentication and encryption features of WEP (Wired Equivalent Privacy). In fact, WPA was
developed by the networking industry in response to the shortcomings of WEP. One of the key
technologies behind WPA is the Temporal Key Integrity Protocol (TKIP). TKIP addresses the
encryption weaknesses of WEP. Another key component of WPA is built-in authentication that WEP
does not offer. With this feature, WPA provides roughly comparable security to VPN tunneling with
WEP, with the benefit of easier administration and use. This is similar to IEEE 802.1x support and

requires a RADIUS server in order to implement. The Wi-Fi Alliance will call this, WPA-Enterprise. One
variation of WPA is called WPA Pre Shared Key or WPA-PSK for short - this provides an
authentication alternative to an expensive RADIUS server. WPA-PSK is a simplified but still powerful
form of WPA most suitable for home Wi-Fi networking. To use WPA-PSK, a person sets a static key or
"passphrase" as with WEP. But, using TKIP, WPA-PSK automatically changes the keys at a preset
time interval, making it much more difficult for hackers to find and exploit them. The Wi-Fi Alliance will
call this, WPA-Personal.
