26 Troubleshooting The Link LED is blinking slowly and you cannot connect to a wireless network or the Internet If your card appears to be functioning correctly, but you cannot connect to a network or you have a red wireless icon at the bottom of your screen, the problem may be that there is a mismatch between the network name (SSID) settings in your wireless network properties. Check the SSID settings to see if they match. The SSID is case-sensitive and the spelling on each computer must be exactly the same in order for the card to connect to the wireless router. Note: To check the SSID settings or look for an available network, double-click the Signal Indicator icon to bring up the Wireless Networks screen. Click Add if you do not see the network you are trying to connect to and type in the SSID. For more information about setting up an SSID, refer to your router manufacturer's user guide. The Link LED is solid, but you cannot connect to the Internet If you have a signal but cannot get online or obtain an IP address, the problem may be that there is a mismatch between the encryption key settings in your computer and wireless router. Check the WEP key settings to see if they match. The key is case-sensitive and the spelling on each computer and wireless router must be exactly the same in order for the card to connect to the router. For more information about encryption, see "Securing your Wi-Fi® Network" on page 15. The data transfer is sometimes slow or signal strength is poor Wireless technology is radio-based, which means connectivity and the throughput performance between devices decreases when the distance between devices increases. Other factors that cause signal degradation are obstructions such as walls and metal appliances. As a result, the typical indoor range of your wireless devices will be between 100 to 200 feet. Note also that connection speed may decrease as you move farther from the wireless router. In order to determine if wireless issues are related to range, we suggest temporarily moving the computer, if possible, to five to 10 feet away from the wireless router. See "Placement of your wireless networking hardware for optimal performance" on page 23. Changing the wireless channel - Depending on local wireless traffic and interference, switching the wireless channel of your network can improve performance and reliability. The default channel the router is shipped with is channel 11. You may choose from several other channels depending on your region; see your router's (or access point's) user manual for instructions on how to choose other channels.
