Frequently Asked Questions (FAQ)

What and how to nd my PC’s IP and MAC address?
IP address is the identier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route

messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as

four numbers separated by periods. Each number can be zero to 255. For example, 192.168.1.254 could be an IP address.

The MAC (Media Access Control) address is your computer’s unique hardware number. (On an Ethernet LAN, it’s the same as
your Ethernet address.) When you’re connected to the Internet from your computer (or host as the Internet protocol thinks
of it), a correspondence table relates your IP address to your computer’s physical (MAC) address on the LAN.

To nd your PC’s IP and MAC address:

• Open the Command program in the Microsoft Windows.

• Type in ipcong /all then press the Enter button.

• Your PC’s IP address is the one entitled IP Address and your PC’s MAC address is the one entitled Physical Address.

What is Wireless LAN?

A wireless LAN (WLAN) is a network that allows access to Internet without the need for any wired connections to the user’s
machine.

What are ISM bands?
ISM stands for Industrial, Scientic and Medical; radio frequency bands that the Federal Communications Commission
(FCC) authorized for wireless LANs. The ISM bands are located at 915 +/- 13 MHz, 2450 +/- 50 MHz and 5800 +/- 75 MHz.

How does wireless networking work?

The 802.11 standard dene two modes: infrastructure mode and ad hoc mode. In infrastructure mode, the wireless network

consists of at least one access point connected to the wired network infrastructure and a set of wireless end stations. This

conguration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs forming a
single subnetwork. Since most corporate WLANs require access to the wired LAN for services (le servers, printers, Internet

links) they will operate in infrastructure mode.

Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set, or IBSS) is simply a set of 802.11
wireless stations that communicate directly with one another without using an access point or any connection to a wired
network. This mode is useful for quickly and easily setting up a wireless network anywhere that a wireless infrastructure

does not exist or is not required for services, such as a hotel room, convention center, or airport, or where access to the

wired network is barred (such as for consultants at a client site).

What is BSSID?

A six-byte address that distinguishes a particular a particular access point from others. Also know as just SSID. Serves as

a network ID or name.

What is ESSID?

The Extended Service Set ID (ESSID) is the name of the network you want to access. It is used to identify different wireless

networks.

What are potential factors that may causes interference?

Factors of interference:

• Obstacles: walls, ceilings, furniture… etc.

• Building Materials: metal door, aluminum studs.

• Electrical devices: microwaves, monitors and electrical motors.

Solutions to overcome the interferences:

• Minimizing the number of walls and ceilings.

• Position the WLAN antenna for best reception.

• Keep WLAN devices away from other electrical devices, eg: microwaves, monitors, electric motors, … etc.

• Add additional WLAN Access Points if necessary.

What are the Open System and Shared Key authentications?

IEEE 802.11 supports two subtypes of network authentication services: open system and shared key. Under open system
authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless
station sends an authentication management frame that contains the identity of the sending station. The receiving station
then returns a frame that indicates whether it recognizes the sending station. Under shared key authentication, each
wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11
wireless network communications channel.

What is WEP?

An optional IEEE 802.11 function that offers frame transmission privacy similar to a wired network. The Wired Equivalent
Privacy generates secret shared encryption keys that both source and destination stations can use to alert frame bits to
avoid disclosure to eavesdroppers.

WEP relies on a secret key that is shared between a mobile station (e.g. a laptop with a wireless Ethernet card) and an
access point (i.e. a base station). The secret key is used to encrypt packets before they are transmitted, and an integrity

check is used to ensure that packets are not modied in transit.

What is Fragment Threshold?

The proposed protocol uses the frame fragmentation mechanism dened in IEEE 802.11 to achieve parallel transmissions.

A large data frame is fragmented into several fragments each of size equal to fragment threshold. By tuning the fragment

threshold value, we can get varying fragment sizes. The determination of an efcient fragment threshold is an important

issue in this scheme. If the fragment threshold is small, the overlap part of the master and parallel transmissions is large.
This means the spatial reuse ratio of parallel transmissions is high. In contrast, with a large fragment threshold, the overlap
is small and the spatial reuse ratio is low. However high fragment threshold leads to low fragment overhead. Hence there
is a trade-off between spatial re-use and fragment overhead.

Fragment threshold is the maximum packet size used for fragmentation. Packets larger than the size programmed in this
eld will be fragmented.

If you nd that your corrupted packets or asymmetric packet reception (all send packets, for example). You may want to try

lowering your fragmentation threshold. This will cause packets to be broken into smaller fragments. These small fragments,
if corrupted, can be resent faster than a larger fragment. Fragmentation increases overhead, so you’ll want to keep this

value as close to the maximum value as possible.

What is RTS (Request To Send) Threshold?

The RTS threshold is the packet size at which packet transmission is governed by the RTS/CTS transaction. The IEEE

802.11-1997 standard allows for short packets to be transmitted without RTS/CTS transactions. Each station can have a
different RTS threshold. RTS/CTS is used when the data packet size exceeds the dened RTS threshold. With the CSMA/

CA transmission mechanism, the transmitting station sends out an RTS packet to the receiving station, and waits for the
receiving station to send back a CTS (Clear to Send) packet before sending the actual packet data.

This setting is useful for networks with many clients. With many clients, and a high network load, there will be many more
collisions. By lowering the RTS threshold, there may be fewer collisions, and performance should improve. Basically, with a
faster RTS threshold, the system can recover from problems faster. RTS packets consume valuable bandwidth, however, so
setting this value too low will limit performance.

What is Beacon Interval?

In addition to data frames that carry information from higher layers, 802.11 includes management and control frames that

support data transfer. The beacon frame, which is a type of management frame, provides the “heartbeat” of a wireless LAN,

enabling stations to establish and maintain communications in an orderly fashion.

Beacon Interval represents the amount of time between beacon transmissions. Before a station enters power save mode,
the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered
frames at the access point).

What is Preamble Type?

There are two preamble types dened in IEEE 802.11 specication. A long preamble basically gives the decoder more time
to process the preamble. All 802.11 devices support a long preamble. The short preamble is designed to improve efciency
(for example, for VoIP systems). The difference between the two is in the Synchronization eld. The long preamble is 128

bits, and the short is 56 bits.

What is SSID Broadcast?

Broadcast of SSID is done in access points by the beacon. This announces your access point (including various bits of

information about it) to the wireless world around it. By disabling that feature, the SSID congured in the client must match

the SSID of the access point.

Some wireless devices don’t work properly if SSID isn’t broadcast (for example the D-link DWL-120 USB 802.11b adapter).
Generally if your client hardware supports operation with SSID disabled, it’s not a bad idea to run that way to enhance
network security. However it’s no replacement for WEP, MAC ltering or other protections.

What is Wi-Fi Protected Access (WPA)?

Wi-Fi’s original security mechanism, Wired Equivalent Privacy (WEP), has been viewed as insufcient for securing condential

business communications. A longer-term solution, the IEEE 802.11i standard, is under development. However, since the

IEEE 802.11i standard is not expected to be published until the end of 2003, several members of the WI-Fi Alliance
teamed up with members of the IEEE 802.11i task group to develop a signicant near-term enhancement to Wi-Fi security.

Together, this team developed Wi-Fi Protected Access.

To upgrade a WLAN network to support WPA, Access Points will require a WPA software upgrade. Clients will require a
software upgrade for the network interface card, and possibly a software update for the operating system. For enterprise
networks, an authentication server, typically one that supports RADIUS and the selected EAP authentication protocol, will
be added to the network.

What is WPA2?

It is the second generation of WPA. WPA2 is based on the nal IEEE 802.11i amendment to the 802.11 standard.

What is 802.1x Authentication?

802.1x is a framework for authenticated MAC-level access control, denes Extensible Authentication Protocol (EAP) over
LANs (WAPOL). The standard encapsulates and leverages much of EAP, which was dened for dial-up authentication with
Point-to-Point Protocol in RFC 2284.

Beyond encapsulating EAP packets, the 802.1x standard also denes EAPOL messages that convey the shared key

information critical for wireless security.

What is Temporal Key Integrity Protocol (TKIP)?

The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wireless LANs.

TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP
provides per-packet key mixing, a message integrity check and a re-keying mechanism, thus xing the aws of WEP.

What is Advanced Encryption Standard (AES)?

Security issues are a major concern for wireless LANs, AES is the U.S. government’s next-generation cryptography algorithm,

which will replace DES and 3DES.

What is Inter-Access Point Protocol (IAPP)?

The IEEE 802.11f Inter-Access Point Protocol (IAPP) supports Access Point Vendor interoperability, enabling roaming of

802.11 Stations within IP subnet.

IAPP denes messages and data to be exchanged between Access Points and between the IAPP and high layer management
entities to support roaming. The IAPP protocol uses TCP for inter-Access Point communication and UDP for RADIUS request/
response exchanges. It also uses Layer 2 frames to update the forwarding tables of Layer 2 devices.

What is Wireless Distribution System (WDS)?

The Wireless Distribution System feature allows WLAN AP to talk directly to other APs via wireless channel, like the wireless
bridge or repeater service.

What is Universal Plug and Play (uPNP)?

UPnP is an open networking architecture that consists of services, devices, and control points. The ultimate goal is to allow

data communication among all UPnP devices regardless of media, operating system, programming language, and wired/

wireless connection.

What is Maximum Transmission Unit (MTU) Size?

Maximum Transmission Unit (MTU) indicates the network stack of any packet is larger than this value will be fragmented

before the transmission. During the PPP negotiation, the peer of the PPP connection will indicate its MRU and will be
accepted. The actual MTU of the PPP connection will be set to the smaller one of MTU and the peer’s MRU. The default is

value 1400.

What is Clone MAC Address?

Clone MAC address is designed for your special application that request the clients to register to a server machine with one

identied MAC address.

Since that all the clients will communicate outside world through the WLAN Broadband Router, so have the cloned MAC
address set on the WLAN Broadband Router will solve the issue.

What is DDNS?

DDNS is the abbreviation of Dynamic Domain Name Server. It is designed for user own the DNS server with dynamic WAN
IP address.

What is NTP Client?

NTP client is designed for fetching the current timestamp from internet via Network Time protocol. User can specify time
zone, NTP server IP address.
