56 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.TroubleshootingCheck that the IP Address assigned to the wireless adapter is within the same IP Address range as the access point and gateway. (Since the DI-524 has an IP Address of 192.168.0.1, 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.) 

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?6. Why can’t I get a wireless connection?If you have enabled Encryption on the DI-524, you must also enable encryption on all wireless clients in order to establish a wireless connection.Make sure that the SSID on the Router and the Wireless Client are exactly the same. If they are not, wireless connection will not be established. For 802.11b, the Encryption settings are: 64, 128, or 256 bit. Make sure that the encryption bit level is the same on the Router and the Wireless Client.  Move the DI-524 and the wireless client into the same room and then test the wireless connection.  Disable all security settings. (WEP, MAC Address Control) Antenna Orientation- Try different antenna orientations for the DI-524. 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 security systems, ceiling fans, and lights, your wireless connection will degrade dramatically or drop altogether. Try changing the Channel on your Router, 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.

60Troubleshooting6. Why can’t I get a wireless connection? (continued)Turn off your DI-524 and the client. Turn the DI-524 back on again, and then turn on the client.  Check that the LED indicators are indicating normal activity. If not, check that the AC power and Ethernet cables are ﬁrmly connected. Make sure that all devices are set to Infrastructure mode.  Check that the IP Address, subnet mask, gateway and DNS settings are cor-rectly entered for the network.  If you are using 2.4GHz cordless phones, X-10 equipment or other home se-curity systems, ceiling fans, and lights, your wireless connection will degrade dramatically or drop altogether. Try changing the Channel on your DI-524, and on all the devices in your network 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.  7. I forgot my encryption key.Reset the DI-524 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 conﬁguration settings. 

618. Resetting the DI-524 to Factory Default SettingsAfter you have tried other methods for troubleshooting your network, you may choose to Reset the DI-524 to the factory default settings. Remember that D-Link AirPro products network together, out of the box, at the factory default settings. To hard-reset the DI-524 to Factory Default Settings, please do the following:Troubleshooting    After the DI-524 reboots (this may take a few minutes) it will be reset to the factory Default settingsUse a paper clip to press the Reset buttonHold for about 10 seconds and then releaseLocate the Reset button on the back of the DI-524Reset

65Frequently Asked Questions When entering the IP Address of the DI-524 (192.168.0.1), you are not connecting to the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility. To resolve difﬁculties accessing a web utility, please follow the steps below. Step 1 Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on. The following connections require a Crossover Cable: Computer to Computer Computer to Uplink Port Computer to Access Point Computer to Print Server Computer/XBOX/PS2 to DWL-810 Computer/XBOX/PS2 to DWL-900AP+ Uplink Port to Uplink Port (hub/switch) Normal Port to Normal Port (hub/switch) The following connections require a Straight-through Cable: Computer to Residential Gateway/Router Computer to Normal Port (hub/switch) Access Point to Normal Port (hub/switch) Print Server to Normal Port (hub/switch) Uplink Port to Normal Port (hub/switch) Rule of Thumb: ”If there is a link light, the cable is right.” What type of cable should I be using?Why can´t I access the web based conﬁguration?

66Frequently Asked Questions (continued)What type of cable should I be using? (continued)What´s the difference between a crossover cable and a straight-through cable? The wiring in crossover and straight-through cables are different. The two types of cable have different purposes for different LAN conﬁgurations. EIA/TIA 568A/568B deﬁne the wiring standards and allow for two different wiring color codes as illustrated in the following diagram. *The wires with colored backgrounds may have white stripes and may be denoted that way in diagrams found elsewhere.How to tell straight-through cable from a crossover cable: The main way to tell the difference between the two cable types is to compare the wiring order on the ends of the cable. If the wiring is the same on both sides, it is straight-through cable. If one side has opposite wiring, it is a crossover cable. All you need to remember to properly conﬁgure the cables is the pinout order of the two cable ends and the following rules: A straight-through cable has identical ends A crossover cable has different ends It makes no functional difference which standard you follow for straight-through cable ends, as long as both ends are the same. You can start a crossover cable with either standard as long as the other end is the other standard. It makes no functional difference which end is which. The order in which you pin the cable is important. Using a pattern other than what is speciﬁed in the above diagram could cause connection problems. When to use a crossover cable and when to use a straight-through cable: Computer to Computer – Crossover Computer to an normal port on a Hub/Switch – Straight-through Computer to an uplink port on a Hub/Switch - Crossover Hub/Switch uplink port to another Hub/Switch uplink port – Crossover Hub/Switch uplink port to another Hub/Switch normal port - Straight-through Why can´t I access the web based conﬁguration?
