Hi Sam, This is not a bug. 450i is not FCC approved for DFS bands, yet. It has been submitted to the FCC with full test results. We expect approval in early Q1 at which point we will unlock 5.4 band in the software.

This is a US radio running 14.1.1 and I just tried 14.1.2 as well. This is a deal breaker if we can't use the 5.4 band. I am hoping it's a bug...... And if it is, squash it quick Cambium. -- -- Sam Lambie Taosnet Wireless Tech. 575-758-7598 Office www.Taosnet.com<http://www.newmex.com>
