Vantage RADIUS 50 Quick Start Guide
Make sure that you have the correct power adaptor connected to the device and
plugged in to an appropriate power source. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you
should contact your local vendor.
Check that you are using the correct username and password and that you have a valid
account. Note that the password is case sensitive.
If your AP uses PEAP authentication, check that you have the correct CA ROOT
Certificate. Changes made to the RADIUS' Server screen require a new certificate to be
downloaded.
If your AP uses MD5 authentication, check that your wireless settings are set up to use
Static Wep Keys. Consult your Wireless AP's user's guide for more information.
The firmware may be corrupt (possible upgrade failure) and should be replaced.
