II. Background Information for Learners
Wireless networking is both pervasive and getting more complicated behind the
scenes. For end users, Wi-Fi is the invisible network resource that they connect
to. For wireless network administrators -- who design, deploy and support the
wireless LAN -- the Wi-Fi network is a fairly complicated beast with many
moving pieces that are part of the bigger networking environment.
Because of the use of radio waves, it is important to fully test a wireless LAN
(WLAN) before letting users start using it. Be certain to perform testing after
installing a WLAN to ensure that the WLAN system satisfies requirements. In
some cases, during operations and maintenance, it might be necessary to
perform testing when troubleshooting problems.

IV. Activity Proper
1. NETWORK CONNECTIVITY TESTING
Many scenarios require you to test things locally on your computer using the command
line. For example, if you are trying to test the connection between your computer and a
remote host, a web-based tool cannot provide this information. It only tests the
connection from its own server to the remote host.
The exact steps to use the ping tools from the command line depend on your
computer's operating system. The basic ping test is one of the easiest things you can
do to verify connectivity between your computer and a remote host. This test is easy to
run from the command line.
Using ping test on Microsoft Windows
1. On your keyboard press Windows Key + R, type CMD the Enter key
2. On command line window type ping + google.com or any domain that you want
to test. Or ping + 192.168.0.10 or any IP address of a device that you want to
test.
Example:
Interpret the output from ping:
If the remote host is active and
configured to respond to ping
requests, responses appear.
Alternatively, if the remote host is
down, or not configured to respond
to ping requests, you do not see any
response.
▪ Reply from: By default, windows will send four ping messages (one on each line)
and then shows you the outcome of each of the four messages.
▪ Bytes: Each ping message request is 32 bytes in size. This is a default setting.
▪ Time: This shows the round trip amount of time in milliseconds (8ms =
0.008seconds). Round trip is the time from when the ping message was sent and
how long it took before the reply came back.
C:>ping google.com

6. 3 | P a g e
▪ TTL (Time-to-Live): The TTL value represents the maximum number of IP routers
that the packet can go through before being thrown away. Currently each router
that the packet travels/hops through will decrement the TTL field by exactly one.
Windows default TTL is 64 therefore if you ping a device on your local home
wireless/network then the ping will not cross any routers and the TTL should remain
at the default. As you can see from the google.com ping example (above) the TTL
went down to 113 so the packet had to hop across a few routers before it got to
google.com.
▪ Request Timeout: The destination IP/hostname or website did not respond. They
could be due to a number of reasons such as; the device does not exist, is not
powered on or is configure not to reply to ping requests. You can create a rule in
windows firewall to stop you PC/Laptop from replying to Pings. Some websites or
online resources do this via a commercial firewall so that hacker cannot target their
systems. If a device does not respond to ping then a hack may pressure that the IP
address / hostname they are pinging does not exist and they may move on till they
find something that does so that they can then start targeting attacks to that IP
address.
WIRELESS LAN TESTING
It is important to conduct wireless LAN (WLAN) testing to ensure your system meets security
and performance requirements. Since there are various factors at play when it comes to
WLAN testing, careful planning and documentation of a WLAN test are as important as
the testing itself.
Wireless LAN Testing Considerations
✓ Signal coverage testing: Signal coverage testing determines where client
devices are able to satisfy coverage requirements. This testing may be part of
performing a WLAN site survey or done after the network is installed to
determine the as-installed signal coverage.
✓ Performance testing: Performance testing determines whether the WLAN can
satisfy user needs for using specific applications over the WLAN.
✓ In-motion testing: In-motion testing determines whether users can continue to
make use of applications while roaming throughout the coverage areas,
especially when the roaming requires handoffs between access points.
✓ Security vulnerability testing: Security vulnerability testing ensures that the
WLAN implements required security mechanisms and offers sufficient protection
to unauthorized access and passive monitoring.
✓ Acceptance/verification testing: After installing a WLAN, it is important to run a
series of acceptance/verification tests to ensure that the WLAN satisfies all
requirements. This is especially important if the organization is having a
contractor install the WLAN.
✓ Simulation testing: In some cases, such as when implementing a very large
WLAN, it may be beneficial to simulate the behavior of the WLAN before actually
installing it. This can provide helpful feedback when designing the system,
especially if the WLAN will have critical performance requirements.
✓ Prototype testing: Prototype testing involves implementing an individual
function of the WLAN that is not well understood before deploying the complete
system. For example, an organization may not be very familiar with 802.1X

7. 4 | P a g e
authentication systems and may benefit by implementing the 802.1X
authentication in a lab environment with a limited number of test client devices.
✓ Pilot testing: Before installing the WLAN across the entire organization, which
may include numerous buildings and different applications, it is strongly
advisable to install the system in a limited number of facilities (ideally one) and
make that one work effectively first. After you work out all the problems, you can
install the WLAN at the remaining location without the need for extensive rework
because the problems will likely have been solved during the pilot testing.
DEVICE SYSTEM SETTINGS CONFIGURATION
Important: Please note that all network devices are different and as such may require
different configuration steps. This document contains a step-by-step process for
configuring TP-Link wireless device. If you have a new, in-the-box TP-Link device, this
guide is for you.
Please connect a computer to TP-Link router by cable or through wireless network. It’s
recommended to
configure it by a wired
connection.
Log into the router’s
web-based utility

If you don't know how to choose the appropriate connection type, click the Detect button
to allow the Router to automatically search your Internet connection for servers and
protocols. The connection type will be reported when an active Internet service is
successfully detected by the Router. This report is for your reference only. To make sure
the connection type your ISP provides, please refer to the ISP. The various types of
Internet connections that the Router can detect are as follows:
o PPPoE - Connections which use PPPoE that requires a user name and password.
o Dynamic IP - Connections which use dynamic IP address assignment.
o Static IP - Connections which use static IP address assignment.
IP Address - The IP address assigned by your ISP dynamically.
Subnet Mask - The subnet mask assigned by your ISP dynamically.
Default Gateway - The default gateway assigned dynamically by your ISP.
Click the Renew button to renew the IP parameters from your ISP.

Click the Release button to release the IP parameters from your ISP.
MTU Size (in bytes) - The normal MTU (Maximum Transmission Unit) value for most Ethernet
networks is 1500 Bytes. For some ISPs you need to modify the MTU. But this is
rarely required, and should not be done unless you are sure it is necessary for your
ISP connection.
If your ISP gives you one or two DNS IP addresses, select Set DNS server manually and enter
the DNS Server and Secondary DNS Server into the correct fields. Otherwise,
the DNS servers will be assigned from ISP dynamically.
Primary DNS - Enter the DNS IP address in dotted-decimal notation provided by your ISP.
Secondary DNS - Enter another DNS IP address in dotted-decimal notation provided by your
ISP.
Note: If you get Address not found error when you access a Web site, it is likely that your DNS
servers are set up improperly. You should contact your ISP to get DNS server
addresses.
Host Name - This option specifies the Host Name of the Router.
Get IP with Unicast - A few ISPs' DHCP servers do not support the broadcast applications. If
you can't get the IP Address normally, you can choose Unicast. (You generally
need not to check this option).
Click the Save button to save your settings.

2. Reflection
Latency and ping are often used interchangeably, although they are subtly
different. While ping refers to the signal sent from the device to the server,
latency is the time it takes for the ping to return to the device. The unit used to
measure latency is milliseconds or ms.
In online gaming, lag is a noticeable delay (latency) between the action
of players (input) and the reaction of the server supporting the game( like LoL,
ML, Dota 2), which has to be sent back to the client.
In your personal use of computer or mobile phones while connecting to the
internet or playing online games, did you experience high latency or Lag? (You
may use a separate sheet of paper for your answer.
What do you think are the causes of that lag?
What did you do?
You are allowed to express your answer in English, Filipino or Mother Tongue.
