6. Conclusion

These Application Notes describe the configuration steps required to configure the D-Link Access Point and Extender Adapter to support the Avaya VPNremote Phone. All feature functionality of the VPNremote Phone over the wireless 802.11b/g with respect to registration, connection and user experience is the same as using the wireline connection. The D-Link successfully achieved enabling the Avaya VPNremote Phone to function in a wireless environment. The Avaya VPNremote Phone successfully received appropriate IP addresses from the Avaya DHCP server and completed the registration with the Avaya Communication Manager. However, it is recommended that when it is configured in a public area/domain, assign a secure login password to the devices and enable the highest level of encryption.

6.1 Observation

The D-Link DWL-G820 is limited to one device. Connecting additional devices using a hub/switch off the DWL-G820, or connecting another computer thru the Avaya VPNremote Phone will not work. When switching between devices the DWL-G820 must be reset (power off and on). The drawback of the wireless network is that the QoS (Quality of Service) and security are not guaranteed and if there is any interference (i.e., cordless 2.4MHz phone) with the link then the connection may be dropped.

6.2 General Security Tips
When away from the WiFi network, disable Microsoft File and Printer sharing on your laptop (which enables other computers to access resources on your computer) so as not to leave your computer vulnerable to hackers. Use the highest level of encryption available between the two wireless devices. If the interference from other Wireless Access Points or wireless devices in the area is a concern, set the AP and wireless clients to use a non-overlapping channel such as 1, 6 or 11. Change the configuration interface password of the access point before enabling it. Most people overlook this part of setting up a wireless network. Only buy an access point that has upgradeable firmware. This will allow you to take advantage of security enhancements or interface updates. Keep the access point firmware up to date. Upgrade your firmware whenever a new one is available. It will probably contain a new or improved feature.

Notes: Hardware vendors, such as Linksys and D-Link have also announced the use of MIMO (MultipleIn-Multiple-Out) in their products. MIMO allows the signal to be bounced off several antennas and paths so that data delivery is guaranteed. Basically, many unique data streams are passed in the same frequency channel. It is a technology that allows for the boosting of wireless bandwidth and range, effectively providing better performance for wireless multimedia and entertainment systems. D-Link recommends that the DWL-G820 is used with D-Link AirPlus Xtreme G products to gain maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead lower actual data throughput rate.

People use WLAN technology for many different purposes: Mobility - Productivity increases when people have access to data in any location
within the operating range of the WLAN. Management decisions based on real-time information can signicantly improve worker efciency.
Low Implementation Costs - WLANs are easy to set up, manage, change
and relocate. Networks that frequently change can benet from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and
easy and can eliminate the need to pull cable through walls and ceilings. Wireless technology allows the network to go where wires cannot go - even outside the home or ofce.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.
Scalability - WLANs can be congured in a variety of ways to meet the needs of
specic applications and installations. Congurations are easily changed and range from Peer-to-Peer networks suitable for a small number of users to larger Infrastructure networks to accommodate hundreds or thousands of users, depending on the number of wireless devices deployed.
Wireless Basics (continued)
The DWL-2100AP is compatible, in default mode, with the following wireless products:

D-Link AirPlus Xtreme G

DWL-G650
Wireless Cardbus Adapters used with laptop computers D-Link AirPlus Xtreme G DWL-G520
Wireless PCI cards used with desktop computers
The DWL-2100AP is also interoperable with other 802.11g and 802.11b standards-compliant devices.
Standards-Based Technology
The DWL-2100AP Wireless Access Point utilizes the 802.11b and the 802.11g standards. The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps (108Mbps in Super G mode) within the 2.4GHz band, utilizing OFDM technology. This means that in most environments, within the specied range of this device, you will be able to transfer large les quickly or even watch a movie in MPEG format over your network without noticeable delays. This technology works by transmitting highspeed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions. The D-Link DWL-2100AP will automatically sense the best possible connection speed to ensure the greatest speed and range possible. 802.11g offers the most advanced network security features available today, including: WPA , TKIP, AES and Pre-Shared Key mode.

Wireless Basics (continued) Installation Considerations
The D-Link AirPlus Xtreme GTM DWL-2100AP lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:
Keep the number of walls and ceilings between the DWL-2100AP and other network devices to a minimum - each wall or ceiling can reduce your DWL-2100APs range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception. Building materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.

Current DHCP Static Pools-These are IP address pools to which the DHCP server
function has assigned static IP addresses.
Binding MAC address- The MAC address of a device on the network that
is within the DHCP static IP address pool.

Assigned IP address-

The current corresponding DHCP-assigned static IP address of the device.
If you want to congure the Guest and Internal networks on Virtual LAN (VLANs), the switch and DHCP server you are using must suppport VLANs. As a prerequisite step, congure a port on the switch for handling VLAN tagged packets as described in the IEEE802.1Q standard. (Please see the following page for more information.)
Advanced > Multi-SSID(continued)
Mater SSID The Master SSID and Security cannot be changed here,Those values follow the setting in Home>Wireless. When you Enable Guest SSID you can name each guest SSID.The Security option for these three Guest SSIDs are open System or shared key. Select HEX or ASCII Select 64-,128-,152-bits Select the 1st through the 4th key to b the active key. Enter key here. If you congure enable Guest access and congure internal and Guest networks on VLANs, this eld will be enable. Provide a number between 1 and 4094 for internal VLAN. This will cuase the access point to send DHCP request woth the VLAN tags. The switch and the DHCP server must support VLAN IEEE802.1Q frames.The access point must be able to reach the DHCP Server. Check with the Administator greading the VLAN and DHCP congurations

Select the AP that you want to assign an IP address to and click the IP button. Enter the IP address and IP netmask for the selected device and click OK. You can congure multiple APs with IP addresses all at once. Click on the IP button after youve selected all of the APs you want to assign an IP address. Enter the IP address you want to assign the rst unit and the AP manager will automatically assign sequential IP addresses.

Device Conguration

Click on this button to access the conguration properties of the selected device(s). The device conguration window allows you to congure settings but does not actually apply the settings to the device unless you click the Apply button. You can also save and load conguration les from this window. When you load a conguration le, you must click Apply if you want the settings to be applied to the selected device(s). The Check All button will select all congurable options. Any setting that has a checkmark next to it is applied to the device or saved to the conguration le. The Clear Checks button deselects all congurable options. This feature is useful if you only want to change a few settings. Deselect all items and only check the items that you want to modify. Refresh will revert to the actual device settings of the selected device(s). To save settings to the device, you must click the Apply button. Only settings that have a checkmark next to them will be applied. The open button is used to load a previously saved conguration le. After opening a conguration le, you must click the Apply button to save the settings to the selected device(s). The save button allows you to save a conguration le of the selected device settings. Only settings that have a checkmark next to them are saved. You cannot save a conguration le if you selected more than one device in the device list. The Exit button will close the device conguration window. Any settings that havent been applied will be lost.
Device Conguration>General When selecting multiple devices for conguration, some options are unavailable for conguration as noted(*) below: Device Name(*): This allows you to change the device name for the selected access point. You must place a checkmark in the Device Name box to change the name. This option can only be congured when one access point is selected for conguration. IP address and Subnet Mask(*): If youve selected one device for conguration and you want to change the IP address of the device, check the IP Address box. You can then enter an IP address and Subnet Mask for the selected access point. This option is only congurable when one access point is selected for conguration. To congure multiple devices with an IP address at one time, please reference the previous page. Gateway: Enter the IP address of your gateway, typically your router address. DHCP client: There is a pulldown menu to select enabled or disabled. When enabled, the selected device(s) will function as a DHCP client(s). This allows them to receive IP conguration information from a DHCP server. When disabled, the access point(s) must have a static IP address assigned to them.

Assigning a Static IP Address in Windows XP/2000
Note: DHCP-capable routers will automatically assign IP addresses to the computers on the network, using DHCP (Dynamic Host Conguration Protocol) technology. If you are using a DHCP-capable router you will not need to assign static IP addresses. If you are not using a DHCP capable router, or you need to assign a static IP address, please follow these instructions:

Go to Start.

Double-click on Control Panel.
Click on Internet Protocol

(TCP/IP)

Click Properties Double-click on Network

Connections.

Select Use the following IP address in the Internet Protocol (TCP/IP) Properties window (shown below)

D-Link DWL-G650

Click Properties.

Input your IP address and
subnet mask. (The IP addresses on your network must be within the same range. For example, if one computer has an IP address of 192.168.0.2, the other computers should have IP addresses that are sequential, like 192.168.0.3 and 192.168.0.4. The subnet mask must be the same for all the computers on the network.)

Input your DNS server

addresses. (Note: If you are entering a DNS server, you must enter the IP Address of the Default Gateway.)
The DNS server information will be supplied by your ISP (Internet Service Provider.)

6. Why cant I get a wireless connection?
If you have enabled encryption on the DWL-2100AP, you must also enable encryption on all wireless clients in order to establish a wireless connection.
The encryption settings are: 64-, 128-, or 152-bit. Make sure that the encryption
bit level is the same on the access point and the wireless client.
Make sure that the SSID on the access point and the wireless client are exactly
the same. If they are not, wireless connection will not be established.
Move the DWL-2100AP and the wireless client into the same room and then
test the wireless connection.
Disable all security settings. (WEP, MAC Address Control) 82
6. Why cant I get a wireless connection? (continued) Turn off your DWL-2100AP and the client. Turn the DWL-2100AP back on again,
and then turn on the client.
Make sure that all devices are set to Infrastructure mode. Check that the LED indicators are indicating normal activity. If not, check that
the AC power and Ethernet cables are rmly connected.
Check that the IP address, subnet mask, and gateway settings are correctly

entered for the network.

If you are using 2.4GHz cordless phones, X-10 equipment or other home security systems, ceiling fans, and lights, your wireless connection will degrade dramatically or drop altogether. Try changing the channel on your DWL-2100AP, and on all the devices in your network to avoid interference. RF noise, like microwaves, monitors, electric motors, etc.
Keep your product away (at least 3-6 feet) from electrical devices that generate 7. I forgot my encryption key. Reset the DWL-2100AP to its factory default settings and restore the other
devices on your network to their default settings. You may do this by pressing the Reset button on the back of the unit. You will lose the current conguration settings.
8. Resetting the DWL-2100AP to Factory Default Settings
After you have tried other methods for troubleshooting your network, you may choose to Reset the DWL-2100AP to the factory default settings.
To hard-reset the D-Link DWL-2100AP to the Factory Default Settings, please do the following:
Locate the Reset button on the back of the

DWL-2100AP.

Use a paper clip to press the Reset button. Hold for about 5 seconds and then release. After the DWL-2100AP reboots (this may take a few 84
minutes) it will be reset to the factory Default settings.
