Possible Solution
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.
Re-check your Network Authentication, Encryption, and Security settings.
Incorrectly configured security settings such as an incorrectly typed WEP key, a mis-
configured LEAP username, or an incorrectly chosen authentication method will
cause the LAN device to associate but not authenticate to the wireless network.
This only applies to networks using static IP addresses. Please contact your network
administrator for the correct settings.
