Wireless Connection Problems

Check the following items before you contact local Technical Support.
1. If wireless clients cannot access the network, check the following:
• Be sure the access point and the wireless clients are configured with the same
Service Set ID (SSID).
• If authentication or encryption are enabled, ensure that the wireless clients are
properly configured with the appropriate authentication or encryption keys.
2. If the access point cannot be configured using a web browser:
• Be sure to have configured the access point with a valid IP address, subnet
mask and default gateway.
• If you are connecting to the access point through the wired Ethernet interface,
check the network cabling between the management station and the access
point. If you are connecting to access point from a wireless client, ensure that
you have a valid connection to the access point.
3. If you forgot or lost the password:
• Set the access point to its default configuration by pressing the reset button
on the back panel for 5 seconds or more. Connect to the web management
interface using the default IP address 192.168.1.1. Then use the default user
name and password "smcadmin" to access the management interface.

corresponding device.
