The router password
Before assigning an IP address it is important to understand how IP addresses work
and the impact this can have on the performance of the system and the
ComWiFi.
IP Address Information
Each TCP/IP node on a network host has a unique IP address. This address provides
the information needed to forward packets on the local network and across multiple
networks if necessary.
IP addresses are specified as
x.x.x.x
, where each x is a number from 1 to 254; for
example, 192.168.0.200. The
ComWiFi
must be assigned a unique IP address to use
on a TCP/IP network. If the address is left blank or is programmed as 0.0.0.0 the
ComWiFi
module will try to automatically obtain an IP address from a DHCP server (if
one is running on the network).
Port Numbers
The port number used to identify the channel for remote initiated connections. The
default setting is 10001. The range for port settings is: 1-65535 except for the following
reserved ports:

Gateway
The gateway address, or router, allows communication to other LAN/WAN segments.
The gateway address should be the IP address of the router connected to the same
LAN segment as the
ComWiFi
. The gateway address must be within the local
network.
Netmask (Subnet Mask)
A netmask defines the number of bits taken from the IP address that are assigned for
the host section. The default mask is 255.255.255.0 (8 bits).
Automatically Assigned IP Address (DHCP)
DHCP (Dynamic Host Configuration Protocol) is by far the most common method for
routers to assign devices IP addresses so that they can use WiFi or hardwired
connections to access the Internet and other resources on the network.
