Appendix A – FREQUENTLY ASKED QUESTIONS  
(FAQ)  
1. What is and how to find my Computers IP and MAC address?  
IP address is the identifier 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, 191.168.1.254 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 find your PC’s IP and MAC address,  
1. Open the DOS Command program in the Microsoft Windows.

2. Type in ipconfig /all then press the Enter button.  
3. Your PC’s IP address is the one entitled IP Address and your PC’s MAC address is the  
one entitled Address.  
2. 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.  
3. What are ISM bands?  
ISM stands for Industrial, Scientific 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.  
4. How does wireless networking work?  
The 802.11 standard define 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 configuration  
53

Wireless RouterRNX-N400LX  
User Manual  
is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or  
more BSSs forming a single sub-network. Since most corporate WLANs require access  
to the wired LAN for services (file servers, printers, Internet links) they will operate in  
infrastructure mode.  
Example 1: wireless 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).  
Example 2: wireless Ad Hoc Mode  
5. What is BSSID?  
BSSID is a six-byte address that distinguishes a particular a particular access point from  
others. BSSID also know as SSID which serves as a network ID or name.

6. 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.  
7. 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 that wireless signal has to go  
through  
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.  
8. 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.  
9. What is WEP?  
WEP is an optional IEEE 802.11 function that offers frame transmission privacy similar  
to a wired network. The Wired Equivalent Privacy (WEP) generates secret shared  
55  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Wireless RouterRNX-N400LX  
User Manual  
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 modified in transit.  
10. What is Fragment Threshold?  
The proposed protocol uses the frame fragmentation mechanism defined 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 efficient 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 field will be fragmented. If you find 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.  
11. 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 defined 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  
56  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Wireless RouterRNX-N400LX  
User Manual  
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.  
12. 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).  
13. What is Preamble Type?  
There are two preamble types defined in IEEE 802.11 specification. 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 efficiency (for  
example, for VoIP systems). The difference between the two is in the Synchronization  
field. The long preamble is 128 bits, and the short is 56 bits.  
14. 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 configured 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 filtering or other  
protections.  
15. What is Wi-Fi Protected Access (WPA)?  
57  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Wireless RouterRNX-N400LX  
User Manual  
Wi-Fi’s original security mechanism, Wired Equivalent Privacy (WEP), has been viewed  
as insufficient for securing confidential 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  
significant 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.  
16. What is WPA2?  
It is the second generation of WPA which based on the final IEEE 802.11i amendment to  
the 802.11 standard.  
17. What is 802.1x Authentication? Protocol (TKIP)?  
802.1x is a framework for authenticated MAC-level access control, defines Extensible  
Authentication Protocol (EAP) over LANs (WAPOL). The standard encapsulates and  
leverages much of EAP, which was defined for dial-up authentication with Point-to-Point  
Protocol in RFC 2284. Beyond encapsulating EAP packets, the 802.1x standard also  
defines EAPOL messages that convey the shared key information critical for wireless  
security.  
18. What is Temporal Key Integrity Protocol (TKIP)?  
The Temporal Key Integrity Protocol (TKIP), 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 fixing the flaws of WEP.  
19. What is Advanced Encryption Standard (AES)?  
58

Wireless RouterRNX-N400LX  
User Manual  
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.  
20. 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 defines  
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.  
21. 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.  
22. 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.  
23. 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.  
24. 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 identified 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.  
25. What is DDNS?  
DDNS is the abbreviation of Dynamic Domain Name Server. It is designed for users who  
own the DNS server to utilize dynamic WAN IP address.  
26. 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.  
27. What is VPN?  
VPN is the abbreviation of Virtual Private Network. It is designed for creating point-to  
point private link via shared or public network.  
28. What is IPSEC?  
IPSEC is the abbreviation of IP Security. It is used to transferring data securely under  
VPN.  
29. What is WLAN Block Relay between Clients?  
An Infrastructure Basic Service Set is a BSS with a component called an Access Point  
(AP). The access point provides a local relay function for the BSS. All stations in the BSS  
communicate with the access point and no longer communicate directly. All frames are  
relayed between stations by the access point. This local relay function effectively doubles  
the range of the IBSS.  
30. What is WMM?  
WMM is based on a subset of the IEEE 802.11e WLAN QoS draft standard. WMM adds  
prioritized capabilities to Wi-Fi networks and optimizes their performance when multiple  
concurring applications, each with different latency and throughput requirements,  
compete for network resources. By using WMM, end-user satisfaction is maintained in a  
60

Wireless RouterRNX-N400LX  
User Manual  
wider variety of environments and traffic conditions. WMM makes it possible for home  
network users and enterprise network managers to decide which data streams are most  
important and assign them a higher traffic priority.  
31. What is WLAN ACK TIMEOUT?  
ACK frame has to receive ACK timeout frame. If remote does not receive in specified  
period, it will be retransmitted.  
32. What is Modulation Coding Scheme (MCS)?  
MCS is Wireless link data rate for 802.11n. The throughput/range performance of an AP  
will depend on its implementation of coding schemes. MCS includes variables such as  
the number of spatial streams, modulation, and the data rate on each stream. Radios  
establishing and maintaining a link must automatically negotiate the optimum MCS  
based on channel conditions and then continuously adjust the selection of MCS as  
conditions change due to interference, motion, fading, and other events.  
33. What is Frame Aggregation?  
Every 802.11 packet, no matter how small, has a fixed amount of overhead associated  
with it. Frame Aggregation combines multiple smaller packets together to form one larger  
packet. The larger packet can be sent without the overhead of the individual packets. This  
technique helps improve the efficiency of the 802.11n radio allowing more end user data  
to be sent in a given time.  
34. What is Guard Intervals (GI)?  
A GI is a period of time between symbol transmissions that allows reflections (from  
multipath) from the previous data transmission to settle before transmitting a new symbol.  
The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns (long). Support  
of the 400ns GI is optional for transmit and receive. The purpose of a guard interval is to  
introduce immunity to propagation delays, echoes, and reflections to which digital data is  
normally very sensitive.
