Networking Basics (continued) Checking the IP Address in Windows XP This window will appear.  Click the Support tab.  Click Close. Assigning a Static IP Address in Windows XP/2000 Note: DHCP-capable routers will automatically assign IP addresses to the comput- ers on the network, using DHCP (Dynamic Host Configuration Protocol) technol- ogy. 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. 34

Networking Basics (continued) Assigning a Static IP Address in Windows XP/2000  Double-click on Network Connections.  Right-click on Local Area Connections.  Double-click on Properties. 35

Networking Basics (continued) Assigning a Static IP Address in Windows XP/2000  Click on Internet Protocol (TCP/IP)  Click Properties  In the window below, select Use the following IP address. 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). IP Address: e.g., 192.168.0.2 Subnet Mask: 255.255.255.0 Default Gateway: Enter the LAN IP address of the wireless router. (D-Link wireless routers have a LAN IP address of 192.168.0.1)  Select Use the following DNS server addresses. Enter the LAN IP address of the wireless router. (D-Link wireless routers have a LAN IP address of 192.168.0.1)  Click OK You have completed the assignment of a static IP address. (You do not need to assign a static IP address if you have a DHCP-capable router). 36

Networking Basics (continued) Checking the Wireless Connection by Pinging in Windows XP and 2000  Go to Start > Run > type cmd. A window similar to this one will appear. Type ping xxx.xxx.xxx.xxx, where xxx is the IP Address of the Wireless Router or Access Point. A good wireless connection will show four replies from the Wireless Router or Access Point, as shown. Checking the Wireless Connection by Pinging in Windows Me and 98  Go to Start > Run > type command. A window similar to this will appear. Type ping xxx.xxx.xxx.xxx where xxx is the IP Address of the Wireless Router or Access Point. A good wireless connection will show four replies from the wireless router or access point, as shown. 37

Troubleshooting This Chapter provides solutions to problems that can occur during the installation and operation of the DWL-7200AP Wireless Access Point. We cover various aspects of the network setup, including the network adapters. Please read the following if you are having problems. Note: It is recommended that you use an Ethernet connection to configure the DWL-7200AP. 1. The computer used to configure the DWL-7200AP cannot access the Configuration menu.  Check that the Ethernet LED on the DWL-7200AP is ON. If the LED is not ON, check that the cable for the Ethernet connection is securely inserted.  Check that the Ethernet adapter is working properly. Please see item 3 in this section: Check that the drivers for the network adapters are installed properly.  Check that the IP address is in the same range and subnet as the DWL-7200AP. Please see Checking the IP Address in Windows XP in the Networking Basics section of this manual. Note: The IP address of the DWL-7200AP is 192.168.0.50. All the computers on the network must have a unique IP address in the same range, e.g., 192.168.0.x. Any computers that have identical IP addresses will not be visible on the network. They must all have the same subnet mask, e.g., 255.255.255.0  Do a Ping test to make sure that the DWL-7200AP is responding. Go to Start>Run>Type Command>Type ping 192.168.0.50. A successful ping will show four replies. Note: If you have changed the default IP address, make sure to ping the cor- rect IP address assigned to the DWL-7200AP. 38

Troubleshooting (continued) 2. The wireless client cannot access the Internet in the Infrastructure mode. Make sure the wireless client is associated and joined with the correct access point. To check this connection: Right-click on the Local Area Connection icon in the taskbar> select View Available Wireless Networks. The Connect to Wireless Network screen will appear. Please make sure you have selected the correct available network, as shown in the illustrations below. default  Check that the IP address assigned to the wireless adapter is within the same IP address range as the access point and gateway. (Since the DWL-7200AP has an IP address of 192.168.0.50, wireless adapters must have an IP address in the same range, e.g., 192.168.0.x. Each device must have a unique IP address; no two devices may have the same IP address. The subnet mask must be the same for all the computers on the network.) To check the IP address assigned to the wireless adapter, double-click on the local area connection icon in the taskbar > select the support tab and the IP address will be displayed. (Please refer to Checking the IP Address in the Networking Basics section of this manual.)  If it is necessary to assign a static IP address to the wireless adapter, please refer to the appropriate section in Networking Basics. If you are entering a DNS server address you must also enter the default gateway address. (Remember that if you have a DHCP-capable router, you will not need to assign a static IP address. See Networking Basics: Assigning a Static IP Address.) 39

Troubleshooting (continued) 3. Check that the drivers for the network adapters are installed properly. You may be using different network adapters than those illustrated here, but this procedure will remain the same, regardless of the type of network adapters you are using.  Go to Start  Right-click on My Computer  Click Properties  Select the Hardware tab  Click Device Manager 40

Troubleshooting (continued)  Double-click on Network adapters  Right-click on D-Link DWL-AG660 Wireless Cardbus Adapter  Select Properties to check that the drivers are in- stalled properly  Look under Device status D-Link DWL-AG660 to check that the device is working properly D-Link DWL-AG660  Click OK 41

Troubleshooting (continued) 4. What variables may cause my wireless products to lose recep- tion? D-Link products let you access your network from virtually anywhere you want. However, the positioning of the products within your environment will affect the wireless range. Please refer to Installation Considerations in the Wireless Basics section of this manual for further information about the most advantageous placement of your D-Link wireless products. 5. Why does my wireless connection keep dropping?  Antenna orientation- Try different antenna orientations for the DWL-7200AP. Try to keep the antenna at least 6 inches away from the wall or other objects.  If you are using 2.4GHz cordless phones, X-10 equipment or other home secu- rity systems, ceiling fans, and lights, your wireless connection will degrade dra- matically or drop altogether. Try changing the channel on your access point and wireless adapter to a different channel to avoid interference.  Keep your product away (at least 3-6 feet) from electrical devices that generate RF noise, like microwaves, monitors, electric motors, etc. 6. Why can’t I get a wireless connection? To establish a wireless connection, while enabling Encryption on the DWL-7200AP, you must also enable encryption on the wireless client.  For 802.11a, 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.  For 802.11b, the Encryption settings are: 64-, 128-, or 256-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. Please note that there are two separate SSIDs for 802.11a and 802.11b. The default SSID for both 802.11a and 802.11b is default. 42

Troubleshooting (continued) 7. Resetting the DWL-7200AP to Factory Default Settings After you have tried other methods for troubleshooting your network, you may choose to Reset the DWL-7200AP to the factory default settings. To hard-reset the D-Link DWL-7200AP to factory default settings, please do the following:  Locate the Reset button on the back of the DWL-7200AP  Use a paper clip to press the Reset button  Hold for about 10 seconds and then release  After the DWL-7200AP reboots (this may take a few minutes) it will be reset to the factory default settings 43
