ADDENDUM 2: Surfer - PC Troubleshooting
PC Operating Systems
Prior to installing Navini Diagnostics monitoring software, please check to insure that the PC
Operating System (OS) meets the criteria given earlier in this manual (section “
Minimum Computing
Requirements
”). If these criteria are not met, unpredictable results may occur as a result of
installation. Also, check to see that you have the latest OS updates installed prior to installing
NavDiag.
Multi-PC Configurations
The Surfer Modem is connected
to a PC via an Ethernet connection. It is possible to connect multiple
PC devices to a single Modem using a hub. The multi-PC configuration is transparent to PC users
and is analogous to a multi-PC configuration on a normal Ethernet Local Area Network (LAN).
Check with your Service Provider to see if multiple IP addressing is required for your particular
configuration. IP addresses can be assigned to the devices dynamically via a DHCP server, as Fixed
or Static IP assignments, or Point-to-Point Protocol Over Ethernet (PPPoE).
When a PC that is connected to a Surfer Modem also has a wireless network card built in, it is best to
disable it when using Surfer. If the built-in wireless card is required for local networking and Surfer
is used for Internet connections, change the interface metric configuration for Surfer so that the
default gateway is used. (See your Operating System’s User Guide for instructions.)
You may not use a router with the Surfer Modem or Navini Diagnostics software. They will not work
going through a router. Please refer to the figure below for acceptable multi-PC configurations.
