RF interference from 
Access Points or other 
wireless networks

The use of identical or overlapping RF channels can cause 
interference with the operation of the WLAN device. Change 
the channel of your Access Point to a channel that does not 
overlap with the interfering device.

Wireless network 
authentication has 
failed

Re-check your Network Authentication, Encryption, and 
Security settings. Incorrectly configured security settings such 
as an incorrectly typed WEP key, a misconfigured LEAP 
username, or an incorrectly chosen authentication method will 
cause the LAN device to associate but not authenticate to the 
wireless network.

Incorrectly configured 
network settings

Recheck the configuration of your network settings.

Incorrect IP address 
configuration

This only applies to networks using static IP addresses. Please 
contact your network administrator for the correct settings.
