+When in Master mode, DHCP on the NPR Ethernet port is disabled. Follow these steps reconfigure NPR and require a local static IP is setup.

   - Validate connectivity by re-opening the telnet connection to **192.168.0.253**
-==== Changing the IP and Subnet ====
+==== Establishing and Validating and RF Connection ====
+  - When in RF range, NPR should connect. The CONN light will be Green on the Client and TX and RX lights flashing
+  - On the Server, see who is connected by running **who**
+  - On the Client, see connected information by running **status**
+  - Assuming the PC connected to the Master has an IP of 192.168.0.20 and PC connected to the Client has a DHCP assigned address of 192.168.0.65, both devices should be able to ping
+==== Additional Points to Note ====
+  - <color #ed1c24>Be really careful if changing the IP configuration - set the config, check it, check it again, log it, then save and reboot</color>
+  - Set your NIC MTU to 750 to achieve reliable and consistent performance
+  - You always telnet to the modem_IP, which counter-intuitively does not have to be unique on the network. In the default configuration, you would use 192.168.0.253 on all modems when connecting via telnet
