- Fixed issue on PTP with Bridging Disabled, device could not be accessed by the default IP address.
- Removed Remote Device Type option on AP/BHM as this was not functioning properly.
- Removed backup configuration file stored when a cnMaestro configuration is pushed as this was causing issues like 450 SMs losing their configuration and calibration data.
- Routers at some customers sites (behind SM’s) failed to retrieve IP from DHCP server correctly when DHCP OFFER is sent as broadcast.

- Added GUI Red warning text to SNMP.
- Occasional false positive of 450 radios was showing “Bandwidth PLL lock Lost” but operating normally.
- Encryption was reset from “AES” to “None” after upgrading to 16.1. Issue happens on PMP 450m without SFP key only.
