1.1 Features

Internet Access Features
Shared Internet Access:
• All users on the LAN or WLAN can access the Internet through the WN-151ARM, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation).
Built-in ADSL2/2+ Modem:
• The WN-151ARM has a built-in ADSL modem; it supports all common ADSL2/2+ connections.
IPoA, PPPoE, PPPoA, Direct Connection Support:
• The WN-151ARM supports all common connection methods.
Auto-detect Internet Connection Method:
• In most situations, the WN-151ARM can test your ADSL and Internet connection to determine the connection method used by your ISP.
Fixed or Dynamic IP Address:
• On the Internet (ADSL port) connection, the WN-151ARM supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address.
Advanced Internet Functions
Application Level Gateways (ALGs):
• Applications which use non-standard connections or port num bers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally.
Firewall:
• As well as the built-in firewall to protect your LAN, you can define Firewall Rules to determine which incoming and outgoing traffic should be permitted.
7
Page 8
Port Triggering:
• This feature, also called Special Applications, allows you to use Internet applications which normally do not function when used behind a firewall.
Port Forwarding:
• This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy.
Dynamic DNS Support:
• DDNS, when used with the Virtual Servers feature, allows users to connect to Servers on your LAN using a Domain Name, even if you have a dynamic IP address which changes every time you connect.
URL Filter:
• Use the URL Filter to block access to undesirable Web sites by LAN users.
Scheduling:
• Both the URL Filter and Firewall rules can be scheduled to operate only at certain times. This provides great flexibility in controlling Internet -bound traffic.
QoS Support:
• Quality of Service can be used to handle packets so that more important connections receive priority over less important one.
Logs:
• Define what data is recorded in the Logs, and optionally send log data to a Syslog Server. Log data can also be E-mailed to you.
VPN Pass through Support:
• PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
8
Page 9
Wireless Features
Wireless N technology:
• Advanced Wireless N technology for enhanced throughput and coverage. Com plies with 2.4GHz IEEE 802.11n standard and is backward compatible with IEE 802.11b/g standards.
WEP:
• WEP (Wired Equivalent Privacy) encryption key, the key sizes of 64 Bit and 128 Bit are supported. WEP encrypts any data before transmission, providing protection against snoopers.
WPA:
• Similar to WEP, WPA-PSK encrypts any data before transmission, providing protection against snoopers. The WPA-PSK is a newer standard than WEP which provides easier configuration and greater security than WEP.
WPA2-PSK:
• WPA2 encryption key uses the extremely secure AES encryption method which it is recommended f or user who has security breach concern.
802.1x:
• The 802.1x mode is providing for the industrial-strength wireless security of 802.1x authentication and authorization.
Wireless MAC Access Control:
• This feature will check the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can be granted for access.
WPS:
• WPS (Wi-Fi Protected Setup) is the simplest way to build connections between wireless netwo rk clients and this router. Instead of selecting an encryption mode and entering a long encryption passphrase, just press client and router’s WPS push button and the WPS will do the setup for you.
WDS:
• WDS (Wireless Distribution System) allows the Wireless Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge modes are supported.
9
Page 10
LAN Features
Single Port Ethernet Router:
• The WN-151ARM integrated 1-port 10/100Mbps LAN switch with auto MDI-MID-X support.
DHCP Server Support:
• Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The WN-151ARM can act as a DHCP Server for devices on your local LAN and WLAN.
Configuration & Management
Easy Setup:
• WEB user interface, open a browser for configuration.
Configuration File Upload/Download:
• Save (download) the configuration data from WN-151ARM to your personal computer for easy backup.
Restore (upload) a previously-saved configuration file from your personal comput er to WN-151ARM.
Remote Management.
• The WN-151ARM can be managed from any PC on your LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet.
Network Diagnostics:
• You can use the WN-151ARM to perform a Ping or DNS lookup.
10
Page 11
Security Features
• Password - protected Configuration: Password protection is provided to prevent unauthorized users from modifying the configuration data and settings.
• Wireless LAN Security: WPA-802.1x, WPA2-802.1x and WEP and Wireless access control by MAC address are all supported. The MAC-level access control feature can be used to prevent unknown wireless stations from accessing your LAN.
• NAT Protection: An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the WN-151ARM.
• Firewall: All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources.
• Protection against DoS attacks: DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavailable. The WN-151ARM incorporates protection against DoS attacks.

TCP/IP IP Address
Subnet Mask
DHCP Server
IP address for the WN-151ARM, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the WN-151ARM is attached (the same value as the PCs on that LAN segment ).
• If enabled, the WN-151ARM will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled.
• If you are already using a DHCP Server, this setting must be disabled, and the existing DHCP server must be re-configured to treat the WN-151ARM as the default Gateway. See the following section for further details.
• The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. Enter the desired value for the Lease Time, which should be between 1 and 7.
See the following section for further details on using DHCP.
27
Page 28
DHCP
What DHCP Does
DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request.
• The client request is made when the client device starts up (boots).
• The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP
Address.
• The WN-151ARM can act as a DHCP server.
• Windows other non-Server versions of Windows will act as a DHCP client. This is the default
Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client".
• You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.)
Using the WN-151ARM's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can:
• Enable or Disable the WN-151ARM's DHCP Server function.
• Set the range of IP Addresses allocated to PCs by the DHCP Server function.
Note: You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Serve r per LAN segment. If you wish to use another DHCP Server, rather than the WN-151ARM's, the following procedure is required.
• Disable the DHCP Server feature in the WN-151ARM. This setting is on the LAN screen.
• Configure the DHCP Server to provide the WN-151ARM's IP Address as the Default Gateway.
To Configure your computer to use DHCP
This is the default setting for TCP/IP for all non-Server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings.

This option will be selectable under the following conditions:
802.11 Mode: 11b+g+n
Bandwidth: 20MHz + 40MHz auto Channel No.: Channel 5 ~ 9 40MHz spectrum transmission will use up to 5 wireless channels, therefore, between channel 5 ~ 9, you can choose “Up channel” or “Down channel ”. For example, channel 5 and up channel is selected, which means the wireless spectrum transmission will use channel 1 ~ 5. If Enabled, SSID1 and SSID2 will be isolated and operating independently. SSID1 users and SSID2 users will not be able to see each other. Wi-Fi Multi Media (WMM) enhances the data transfer performance of multimedia contents when they’re being transferred over a wireless network. Note: This function can only be available when client’ s wirele ss card also supports WMM feature. Select the desired bandwidth from the list. Note: Do not modify the default value if you aren’t familiar with this function.

3.4 Wireless Security

This screen is accessed by clicking the "Configure SSID" button on the Wireless screen. There are 3 options for Wireless security:
• Disabled - no data encryption is used.
• WEP - data is encrypted using the WEP standard.
• WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and
provides much better security than WEP. If all your Wireless stations support WPA-PSK, you should use WPA-PSK rather than WEP.
• WPA2-PSK - This is a further development of WPA-PSK, and offers even greater security, using the AES (Advanced Encryption Standard) method of encryption.
• Mixed WPA-PSK/WAP2-PSK - This method, sometimes called "Mixed Mode", allows clients to use EITHER WPA-PSK OR WPA2-PSK.
• WPA-802.1x - This version of WPA requires a Radius Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WPA standard.
If this option is selected:
• This Access Point must have a "client login" on the Radius Server.
• Each user must have a "user login" on the Radius Server.
• Each user's wireless client must support 802.1x and provide the login data when required.
• All data transmission is encrypted using the WPA standard. Keys are automatically generated,
so no key input is required.

Normally, this should be left at the default value of "Automatic". If changed to "Open System" or "Shared Key", ensure that your wireless client station uses the same setting. Select the desired option, and ensure the Wireless Stations use the same setting.
• 64 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 64 Bit Encryption, the key size is 10 chars in HEX (0~9 and A~F).
• 128 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 128 Bit Encryption, the key size is 26 chars in HEX (0~9 and A~F).
Select the key you wish to be the default. Transmitted data is ALWAYS encrypted using the Default Key; the other Keys are for decryption only. You must enter a Key Value for the Default Key.

Notes:
• Generally, you should NOT use modem mode. Only select this mode if you are sure this is what you want.
Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, b y default, it acts a DHCP Server, providing an IP address and related information to all Wireless and LAN users. Only the ADSL Modem component is operating.
• All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it.
• You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point.
• All traffic received on either the Wireless or LAN interface will be sent over the ADSL connection.
• After changing the mode, this device will restart, which will take few seconds. The menu will also change, depending on the mode you are in.
• The Wireless Access Point can function in either Router or Modem mode. But generally it is not a good idea to combine a Modem with an Access Point because all data received from the wireless stations will be sent over the modem connection. (Since the modem is transparent, it does not examine the traffic to determine whether the traffic is for the LAN or the WAN.)
• For details on using Modem Mode, see Chapter 8.

5.1 Internet

This screen provides the access to the DMZ, Special Applications and URL Filter features.
Figure: Internet Screen
DMZ
The DMZ host is a local computer exposed to the Internet. For example, if you have a local computer that cannot run an Internet application properly behind the NAT firewall, then you can open the client up to unrestricted two-way access by defining a DMZ host.
Note: The DMZ host is effectively outside the Firewall, making it more vulnerable to be att acked. For this reason, you should only enable the DMZ feature when is necessary.

5.3 Dynamic DNS

DDNS allows mapping of the static domain name to a dynamic IP address. Obtain an account, password and static domain name from the DDNS service providers. This free service is very useful when combining with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
DDNS Services work as follows:
1. You must register for the service at one of the listed DDNS Service providers.
2. After registration, use the Service provider's normal procedure to obtain your desired Domain name.
3. Enter your DDNS data on the WN-151ARM's DDNS screen, and enable the DDNS feature.
4. The WN-151ARM will then automatically ensure that your current IP Address is recorded at the DDNS service provider's Domain Name Server.
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain name, as shown on this screen.

However, if you do use a fixed IP address on some devices on your LAN, you should enter det ails of each such device into the PC database, using the PC Database screen.
PC Database Screen
An example PC Database screen is shown below.
Figure: PC Database
• PCs which are "DHCP Clients" are automatically added to the database, and updated as required.
• The WN-151ARM uses the "Hardware Address" to identify each PC, not the name or IP address. The
"Hardware Address" can only change if you change the PC's network card or adapter.

• Only This Computer - allow access by only one IP address. Enter the
desired IP address.
• IP Address Range - allow access from a range of IP addresses on the Internet. Enter a beginning and ending IP address to define the allowed range.
For security, you should restrict access to as few external IP addresses as practical.
To connect from a remote PC via the Internet
1. Ensure your Internet connection is established, and start your Web Browser.
2. In the "Address" bar, enter "http://" followed by the Internet IP Address of the WN-151ARM. If the port number is not 80, the port number is also required. (After the IP Address, enter ":" followed by the port number.) e.g.
http://123.123.123.123.8080
This example assumes the WAN IP Address is 12 3.123.123.123, and the port number is 8080.
3. You will then be prompted for the login name and password for this device.

6.7 Routing

Overview
You can ignore the “Routing” page if your network topology is constructed as following:
• If you don't have other Routers or Gateways on your LAN.
• If the WN-151ARM is only acting as a Gateway for the local LAN segment, ignore the "Routing" page
even if your LAN has other Routers.
You can ignore the RIP Routing page if your network topology is constructed as following:
• If your LAN has other Gateways and Routers, and you wish to control which LAN segments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure the Static Routing table instead. (You also need to configure the other Routers.)
You can ignore the Static Routing page if your network topology is constructed as following:
• If your LAN has a standard Router (e.g. Cisco) on your LAN, and the WN-151ARM is to act as a Gateway for all LAN segments, you can enable RIP (Routing Information Protocol).
• If using Windows 2000 Data center Server as a software Router, enable RIP on the WN-151ARM, and ensure the following Windows 2000 settings are correct:
• Open Routing and Remote Access
• In the console tree, select Routing and Remote Access, [server name], IP Routing, RIP
• In the "Details" pane, right-click the interface you want to configure for RIP version 2, and then click
"Properties".
• On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and Incoming
packet protocol to "RIP version 1 and 2".
85
Page 86
Routing Screen
The routing table is accessed by the Routing link on the Administration menu.
Using this Screen
Generally, you will use either RIP (Routing Information Protocol) or the Static Routing Table, as explained above, although is it possible to use both methods simultaneously.
Static Routing Table
• If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached.
• The other Routers must also be configured. See this chapter for further details and an example.

Update the current Static Routing Table entry, using the data shown in the table area on screen. Delete the current Static Routing Table entry. Save the RIP setting. This has no ef fect on the Static Routing Table.
Configuring Other Routers on your LAN
It is essential that all IP packets for devices are not on the local LAN be passed to the WN-151ARM, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the WN-151ARM as the Default Route or Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the WN-151ARM. This router requires that the Default Route is the WN-151ARM itself. Typically, routers have a special entry for the Default Route. It should be configured as follows.
Destination IP Address Network Mask
Normally 0.0.0.0, but check your router documentation. Normally 0.0.0.0, but check your router documentation.
Gateway IP Address Metric
The IP Address of the WN-151ARM. 1
87
Page 88
Other Routers on the Local LAN
Other routers on the local LAN must use the WN-151ARM's Local Router as the Default Route. The entries will be the same as the WN-151ARM's local router, with the except ion of the Gateway IP Address.
• For a router with a direct connection to the WN-151ARM's local Router, the Gateway IP Address is the address of the WN-151ARM's local router.
• For routers which must forward packets to another router before reaching the WN-151ARM's local router, the Gateway IP Address is the address of the intermediate router.
Static Routing - Example
Figure: Routing Example

For the WN-151ARM's Routing Table
For the LAN shown above, with 2 routers and 3 LAN segments, the WN-151ARM requires 2 entries as follows.
Entry 1 (Segment 1)
Destination IP Address 192.168.1.0 Network Mask 255.255.255.0 (Standard Class C) Gateway IP Address 192.168.0.100 (WN-151ARM's local
Router)

Overview
There are two modes available on the Mode screen.
• Router - Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, by default, it acts a DHCP Server, providing an IP address and related information to all Wireless and LAN users.
• Modem - Only the ADSL Modem component is operational. All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it. You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point.
This Chapter describes operation while in Modem Mode, also called Bridge Mode.
Management Connections
When this device restarts in Modem mode, the IP address does not change, but the DHCP server is disabled. However, your PC will usually retain the IP address provided by the DHCP Server, so the connection will be automatically re-established. You then need to ensure that the IP address of this modem is suitable for your LAN.
• You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point.
• This Modem/AP must be a valid device on your LAN, to allow management connections. You must assign a (fixed) IP address which is within the address range used on your LAN, but not within the address range used by your DHCP server.
91
Page 92
When you connect in future, just connect normally, using the IP address you as signed.
1. Start your WEB browser.
2. In the Address box, enter "http://" and the current IP Address of the WN-151ARM as in this example, which uses the WN-151ARM 's default IP Address:
http://192.168.1.254
3. When prompted for the User name and Password, enter admin for the use r name, and the current password, as set on the password screen. (The password is the same regardless of the mode.)
Home Screen
If in Modem mode, the home screen will look like the example below.
Figure: Home Screen - Modem Mode

Note: When it sets to Modem mode, the menu has also changed, many of the options in Router mode are not available. The screens available are:
• Mode - change back to Router mode, if desired.
• LAN - set IP address, mask and gateway. This is the same as in Router m ode, except that the DHCP
server is not available while in Modem mode.
• Wireless - this screen, and related sub-screens, is the same as in Router mode.
• Password - this screen is the same as in Router mode.

This field displays the current name of this device. Select the desired device mode for the router:
• Router - Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, by default, it acts a DHCP Server, providing an IP address and related information to all Wireless and LAN users.
• Modem - Only the ADSL Modem component is operational. All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it. You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point. This mode is also called Bridge Mode.
After changing the mode, this device will restart, which will take a few seconds. The menu will also change, depending on th e mode you are in.
Operation
Operation is automatic and transparent.
• Wireless clients can connect to the Access Point if they have the correct SSID and security, but they must obtain an IP address from the DHCP Server on your LAN.
The modem will act like any other ADSL modem. No routing will be performed, a nd no client login will be done. If a client login is required, it must be performed by your Router/Gateway or by software on your PC.

Overview
This chapter covers some common problems that may be encountered while using the WN-151ARM and some possible solutions to them. If you follow the suggested steps and the WN-151ARM still does not function properly, contact your dealer for further advice.

Solution 1:
Check the following:
• The WN-151ARM is properly installed, LAN connections are OK, and it is powered ON.
• Ensure that your PC and the WN-151ARM are on the same network segment. (If you don't have a router, this must be the case.)
• If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it.
• If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.1.1 to 192.168.1.253 and thus compatible with the WN-151ARM's default IP Address of 192.168.1.254. Also, the Network Mask should be set to 255.255.255.0 to match the WN-151ARM. In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.
97
Page 98
Internet Access
Problem 1: When I enter a URL or IP address I get a time out error. Solution 1:
Problem 2: Some applications do not run properly when using the WN-151ARM. Solution 2:
A number of things co uld be causing this. Try the following trouble s hooting steps.
• Check if other PCs work. If they do, ensure that your PCs IP settings are
correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address.
• If the PCs are configured correctly, but still not working, check the
WN-151ARM. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)
• Check the WN-151ARM's status screen to see if it is working correctly.
The WN-151ARM processes the data passing through it, so it is not transparent. For incoming connections, you must use the Virtual Server or Firewall Rules to specify the PC which will receive the incoming traffic. You can also use the DMZ function. This should work with almost every application, but:
• It is a security risk, since the firewall is disabled.
• Only one (1) PC can use this feature.
98
Page 99
Wireless Access
Problem 1: My PC can't locate the Wireless Access Point. Solution 1:
Check the following.
• Your PC is set to Infrastructure Mode. (Access Points are always in
Infrastructure Mode)
• The SSID on your PC and the Wireless Access Point are the same.
Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup".
• Both your PC and the WN-151ARM must have the same setting for WEP.
The default setting for the WN-151ARM is disabled, so your wireless station should also have WEP disabled.
• If WEP is enabled on the WN-151ARM, your PC must have WEP enabled,
and the key must match.
• If the WN-151ARM's Wireless screen is set to Allow Trusted PCs only,
then each of your Wireless stations must have been designated as "Trusted", or the Wireless station will be blocked.
• To see if radio interference is causing a problem, see if connection is
possible when close to the WN-151ARM. Remember that the connection range can be as little as 100 feet in poor environments.
Problem 2: Wireless connection speed is very slow. Solution 2:
The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following:
• WN-151ARM location.
Try adjusting the location and orientation of the WN-151ARM.
• Wireless Channel
If interference is the problem, changing to another channel may show a marked improvement.
• Radio Interference
Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated.
• RF Shielding
Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the WN-151ARM.

Overview
Wireless LANs can work in either of two (2) modes:
• Ad-hoc
• Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
s
s
L
L
A
A
N
N
In Infrastructure Mode, one or more Access Poi nt s are used to conn ect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources.
Note: Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels. As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)
