Assigning an IP address
Before proceeding you should ensure you can access the wireless
router as changes will need to be made to ensure the ComWiFi will
function as expected; and so that you can configure the router to
allow access from the outside world (WAN) should you require.
You will need to know the following; the default information should be
available from the router documentation:
• The router's SSID (wireless network name)
•
The WiFi password
• The IP address of the router
•
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:
Port Numbers Reserved for
1-1024
Reserved (well known ports)
9999
Telnet setup
14000-14009
Reserved
30718
Reserved
10000 - 10999
Recommended for raw socket connections
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.
IP addresses will be assigned, from a "pool" for a "lease" time, and
can change from device day to day; for example when you leave
your home and lose WiFi connection there is no guarantee when you
return that you will be given the same address, it may be in use by
something else.
If you allow the wireless router to automatically assign an IP address
to the ComWiFi you may encounter problems with IP conflicts if:
•
Another device on the network has ever used the address
(and could do so again)
• The ComWiFi is off line and another device is given the
address by the router
To overcome these potential issues it is advised that the IP address is
either reserved for the ComWiFi, or the IP address used for the
ComWiFi is outside of the DHCP Pool.
Accessing the Router
On a PC open the web browser and type the router's IP address into
the address bar as shown and press enter. Values used are typical
only; they may or may not be the same as the router.
When prompted enter the router user name & password and press
Enter.
Once you have access to the router you are looking for DHCP
Settings. The example shown may or may not be the same as the
router. You will see a Start & End IP address, this is the DHCP pool or
the range of addresses used by the router when assigning and
address automatically.
You now know the address range being used by the router. The
Default Gateway is the actual router itself.
So you can now decide how you want to configure the ComWiFi,
either method is valid, but they both require different steps.
Dynamic IP Address (DHCP Reservation
required)
With this method you will be assigned an address from the DHCP
pool and will need to reserve the address for the ComWiFi. On the
WiFi enabled device where you accessed the ComWiFi do the
following.
•
Click on the STA tab on the left side of the screen.
• Ensure Obtain an IP Address Automatically is Enabled.
•
Under the 'Network Name' click on Scan and then select the
WiFi network. This is the name of the wireless router (SSID) that
is connected to the internet.
• Enter the router password if required.
•
Click Save.
• When prompted Restart the device, disconnect from the
ComWiFi
•
Once the device has restarted refresh the page or reconnect to
the ComWiFi and open the STA page.
• Take note of the IP address, subnet mask, Gateway & DNS
Server for the network. For Example
Installation
IP = 192.168.0.100
