The document describes the steps taken to secure a wireless network using Cisco Packet Tracer: 1. The wireless PC was connected to the default wireless network and the network connection was verified. 2. The web utility of the Linksys WRT300N wireless router was accessed using the default credentials to begin securing the network. 3. The SSID was changed from the default and a WEP key was added, requiring reconnection with the new SSID and WEP key.

1. M3 – I.T Essentials Packet Tracer
Lab
Candidate Number: 61101
Centre Number: 1726

2. Step 1: Connect
 Firstly, I opened up Cisco Packet Tracer Lab 9.3.4
and connected WIRELESS PC1 to the network
via accessing the Desktop and selecting ‘PC
Wireless’.

3. Step 2: Veryfying
 Then, I checked that WIRELESS PC1 was
communicating with the network by accessing the
command prompt and typing ‘ipconfig’.

4. Step 3: Web Utility Access
 Next, I selected ‘Web Browser’ on the Desktop to
access the internet. I typed in the code for the
default gateway in the URL and after typing in the
username and password to enable access, I was
able to view the default page of the Linksys
WRT300N web utility.

5. Step 4: Configure SSID
 After this, I starting securing the network. The first
step therefore was to change the default network
name (SSID) from default to WRS1. Once
settings were saved, connection timed out and
this prompted me to reconnect to the network but
to WRS1, the new SSID.

6. Step 5: Extra Secure
 The next step to securing my network was to add a
WEP key. When asking to connect to the network, a
WEP key would now be required. By reconnecting to
the default page of the Linksys WRT300N web utility, I
would navigate to the wireless page and therefore the
wireless security tab and added a random WEP key
(1234567890).

7. Step 6: Reconnecting, again!
 After adding a WEP key and saving settings, I
was timed out again and had to reconnect via
‘Wireless PC’ but this time, the WEP key was
required.

8. Step 7: Changing password and
finishing
 My final step was to change the default password
for the Linksys WRT300N web utility . To do this I
navigated to ‘Administration’ and there I could
change the password. Finally, I connected
WIRELESS PC2 to the network via the same
method and then I was finished!
