If you are still unable to solve the problem by checking the LED activity, the error may be caused by a configuration
mismatch which prevents the W-LAN 11 from establishing a wireless connection with your network. You may check
the following to ensure normal operation of the W-LAN 11.
WEP keys: If data encryption is activated, always remember to set WEP keys exactly the same on
the Access Point as are on the wireless stations.
Access Control: Make sure that the MAC address of your W-LAN 11 is not included in the Access
Control table of other wireless devices.
