Troubleshooting 1. All the settings are correct, but I can not make a wireless connection to the Access Point. 1. Double check that the wireless LED on the Access Point is lit. 2. Power cycle the Access Point. Unplug the power to the Access Point. Wait 15 seconds, then plug the power back in. 3. Contact the manufacturer of your wireless network adapter. Make sure the wireless network adapter is configured with the proper SSID. The default SSID of the Access Point is TRENDnet637. If you have enabled any encryption on the Access Point, make sure to configure the wireless network adapter with the same Pre-shared key. 2. I have a wireless adapter that supports WiFi Protected Setup (WPS) push button setup. How do I setup WPS between the TEW-637AP and my wireless adapter? 1. Press on the WPS button on the front of the TEW-637AP for 10 seconds. 2. Refer to your wireless adapters for instructions on setting up WPS. 3. I inserted the Utility CD-ROM into my computer's CD-ROM Drive but the installation menu does not appear automatically. What should I do 1. For Windows 7, if the installation menu does not appear automatically, click on the Windows Icon on the bottom left hand corner of the screen, click the “Search programs and files” box, and type D:\autorun.exe, where “D” in “D:\autorun.exe” is the letter assigned to your CD-ROM Drive, and then press the ENTER key on your keyboard 2. For Windows Vista, if the installation menu does not appear automatically, click on the Windows Icon on the bottom left hand corner of the screen, click on the “Start Searc”h box, and type D:\autorun.exe, where “D” in “D:\autorun.exe” is the letter assigned to your CD-ROM Drive, and then press the ENTER key on your keyboard. 3. For Windows XP/2000 if the window does not appear automatically, click Start, click Run and type D:\autorun.exe where “D” in “D:\autorun.exe” is the letter assigned to your CD-ROM Drive, and then press the ENTER key on your keyboard. 4. I do not have a DHCP server or DHCP is disabled on my network and I am unable to configure the TEW-637AP. What should I do? 1. Go to the TCP/IP settings on your computer and assign a static IP address on your computer's network adapter in the subnet of 192.168.10.x. Since the default IP address of the TEW-637AP is 192.168.10.100, do not assign a static IP address of 192.168.10.100 on your computer's network adapter. 2. Open Internet Explorer and enter http://192.168.10.100 into the address bar. 7 5. I followed the Quick Installation Guide and setup a new password. When I log in to the browser configuration an access error message appears. What should I do? If the password was changed and you don't remember it, you need to reset the TEW-637AP. To reset the TEW-637AP, power up the unit and wait 30 seconds for the unit to boot up. Then take a pin or paper clip and press the reset button for 15 seconds, then let go. The reset button is located on the bottom of the TEW-637AP. Please note that performing a reset on the TEW-637AP will erase all settings applied and will revert back to default settings. The default user name is admin and the default password is admin. When you log in to the browser configuration for the first time, make sure to enter admin for user name. Do not leave the user name field blank LED/Button Color Sequence Definition PWR (Power) LED Green N/A Solid Off Device is on Device is off LAN port connected at 10/20 Mbps or 100/200Mbps (Half/Full Duplex) Solid Network Port Link/Act LEDs Wireless LED WPS LED Green Blinking LAN port data transmitting/receiving 10/20Mbps or 100/200Mbps (Half/Full Duplex) N/A Green Off Blinking Wireless LAN is on or enabled/Wireless data transmission Wireless LAN is on or enabled/Wireless data transmission N/A Off Wireless LAN is off or disabled Solid WPS authentication process complete Green Blinking WPS authentication in process N/A Off WPS is not activated or disabled Power Switch (EU Version only) N/A N/A Turns on/off power to the TEW-637AP Reset Button WPS Button N/A N/A N/A N/A Hold 15 seconds to reset device to factory defaults.

Assign your network a unique SSID Do not use anything that would be identifying like “Smith Family Network”. Choose something that you would easily identify when searching for available wireless networks. Do not turn off the SSID broadcast The SSID broadcast is intended to be on and turning it off can cause connectivity issues. The preferred method of securing a wireless network is to choose a strong form of encryption with a strong and varied encryption key. Note: after setting up the SSID, encryption type and encryption key/passphrase, please make a note of them for future reference. You will need this information to connect your wireless computers to the wireless router/access point. Change the channel Most wireless access points and routers are defaulted to channel 6. If you have a site survey tool that will display the channels you can plan your channel selection around neighboring access points to minimize interference from them. If your site survey tool does not display the channel try using channels 1 or 11. If you are using 802.11n you should be securing the network with WPA2 security. Note: Due to Wi-Fi certification considerations if you choose WEP, WPA or WPA2-TKIP encryption this device may operate in legacy wireless mode (802.11b/g). You may not get 802.11n performance as these forms of encryption are not supported by the 802.11n specification. Please also make sure that the wireless hardware is not placed in any type of shelving or enclosures. Avoid stacking hardware on top of each other to prevent overheating issues Maintain enough free space around the hardware for good ventilation and airflow. There should also be plenty of free space around the antennas to allow the wireless signal to propagate. There are a number of other environmental factors that can impact the range of wireless devices. 1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at an angle. The more material the signal has to pass through the more signal you will lose. 2. Keep the number of obstructions to a minimum. Each obstruction can reduce the range of a wireless device. Position the wireless devices in a manner that will minimize the amount of obstructions between them. 9 3. Building materials can have a large impact on your wireless signal. In an indoor environment, try to position the wireless devices so that the signal passes through less dense material such as dry wall. Dense materials like metal, solid wood, glass or even furniture may block or degrade the signal. 4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless adapter's site survey tool to determine the best antenna orientation for your wireless devices. 5. Interference from devices that produce RF (radio frequency) noise can also impact your signal. Position your wireless devices away from anything that generates RF noise, such as microwaves, HAM radios, Walkie-Talkies and baby monitors. 6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as 2.4GHz cordless phones or other wireless remotes operating on the 2.4GHz frequency can potentially drop the wireless signal. Although the phone may not be in use, the base can still transmit wireless signals. Move the phone's base station as far away as possible from your wireless devices. If you are still experiencing low or no signal consider repositioning the wireless devices or installing additional access points. The use of higher gain antennas may also provide the necessary coverage depending on the environment. 10 Copyright © 2011. All Rights Reserved. TRENDnet.
