This is a message to the RTM/Pre-sales community out there who currently have PMP320 subscriber modules that are part of a pre-M3 shipment. These units were shipped to you in order to get trial activities started. The current 3.5 or 3.65 CPE that you have in your possession requires a minor hardware change that must be done in an engineering environment. The hardware version you have may exhibity longer DHCP times when within a  -50 to -60 RSSI range. Please respond to this post in order to start the process of replacing your CPE hardware. In addition the PMP320 AP should be upgraded to the latest 3.1 software load.   Thanks Sakid Ahmed PMP320 Engineering
