Wireless Security Guide
This guide will take you through the process of configuring, changing or checking the
wireless security settings on an existing wireless network.
This guide will not assist you to setup a new wireless network. Please refer to the
wireless setup document for your model available from the support section of the
NetComm*or Dynalink** website.
Any changes to your wireless security settings will
require you to reconfigure wirelessly connected
devices to use the new security settings. Please
ensure that you have your wireless setup guide handy
for this.

Step 1: Selecting a wireless security type:
There are a number of different types of wireless security to select from.
Before changing your settings, check the types of security available on your
modem/router and then consult your wireless adapter manufacturer to ensure your
wireless adapter is compatible with your chosen security type.
The most commonly used security types are:
- WEP (64bit or 128bit)
- WPA (Radius)
- WPA-PSK
- WPA2 (Radius)
- WPA2-PSK
The majority of wireless adapters should support one (or all) of the above security
types.
You will be unable to utilise Radius server
authentication without having a Radius server in place
and configured on your network.
Step 2: Selecting a wireless security key:
Once you have chosen which wireless security type you want to use on your network,
you will then need to create your wireless security key or wireless password.
Depending on the security type you choose, you will have the option of using either an
ASCII or HEX format key.
ASCII refers to any letter or number you can see on your keyboard.
HEX refers to the letters A to F and the numbers 0 to 9.
You will need to ensure that your security key is the correct length. Your
modem/router will display the required number of characters (letters and/or numbers)
you need.

Step 3: Setting up your wireless security:
Please ensure that your modem/router is connected to your computer using an
ethernet cable before continuing.
1. Navigate to http://192.168.20.1 in a web browser.
2. Enter “admin” as both the username and password before pressing the Login button.

3. Select the Wireless 2.4 GHZ Tab.
4. This is the basic wireless tab where you have the option to change the wireless
security key. After making any change to the security key select the Save and apply
the changes button.

5. If you would like to use a different wireless security type click on the Switch to
advanced view option at the bottom of the page.

6. Select the Wireless 2.4 GHZ option from the “Network Setup” menu.
7. Select the wireless security type you would prefer to use from the Authentication
field(we’re using WPA-PSK / WPA2-PSK for the example).
8. Select the Encryption type you would prefer to use from the Encryption field. We are
using TKIP / AES for the example.
9. After selecting your desired security and encryption type, enter the wireless security
key you would like to use into the “Pre-Share Key” section and click “Save”.
Any changes to your wireless security settings will require you to reconfigure any wirelessly
connected devices to use the new security settings. You will now need to re-setup any
wirelessly connected computers with the new wireless security key. Please ensure that you
have your wireless setup guide handy for this.
