2. 1. Position Your Modem Router
With the modem router, you can access your network from anywhere within the
wireless network coverage. However, the wireless signal strength and coverage varies
depending on the actual environment where your modem router is in. Many obstacles
may limit the range of the wireless signal, for example, concrete structures, thickness
and number of walls.
For your security and best Wi-Fi performance, please:
• Do Not locate the modem router in the place where it will be exposed to moisture or
excessive heat.
• Keep away from the strong electromagnetic radiation and the device of
electromagnetic sensitive.
• Place the modem router in a location where it can be connected to the various devices
as well as to a power source.
• Make sure the cables and power cord are safely placed out of the way so they do not
create a tripping hazard.

Bandwidth Control
The Bandwidth Control feature is used to fully utilize your limited bandwidth and
optimize the load respectively. With this feature enabled, you can assign a specific
minimum or maximum bandwidth for each computer, thus minimizing the impact
caused when the connection is under heavy load.
Chapter 5
Bandwidth Control
I want to:
Tips:
How can I
do that?
Use an independent bandwidth and enjoy a good Internet
experience without being affected by other users who are
sharing the same router.
For example, my roommate and I share 512Kbps Upstream
Bandwidth and 8Mbps Downstream Bandwidth via this router,
she likes to watch live show and play online games, which may
take up much bandwidth. I don’t want to be affected, so we
agree to equally distribute the bandwidth. Our IP addresses are
192.168.1.101 and 192.168.1.110.
To use the bandwidth control feature, you’d better set static
IP Address on each computer to be controlled or configure
Address reservation on the modem router in order to manage
easily. About how to configure address reservation, please refer
to Reserve LAN IP Addresses.
1. Visit http://tplinkmodem.net, and log in with the password
you set for the modem router.
2. Go to Advanced > Bandwidth Control page.
3. Enable Bandwidth Control, choose DSL on the line type. If
you don’t know how to choose the line type, please contact
your ISP which line type you have access.
4. Enter the Total Upstream Bandwidth and the Total Downstream
Bandwidth given by your ISP. (1Mbps=1024Kbps). Click Save
to save the settings.
5. Click Add to add controlling rules for each computer
respectively.

Chapter 5
Bandwidth Control
1 ) IP Range: Enter the IP address. The field can be single IP
address or IP address range according to your demands.
When you configure the single IP address, the computer
with this IP address will get independent given
bandwidth. When you configure the IP address range, all
computers in the range will share the given bandwidth.
2 ) Port Range: Keep the default settings. The default port
range of TCP protocol or UDP protocol is from 1 to 65535.
3 ) Protocol: Keep the default setting. Or you can choose the
TCP protocol or UDP protocol or both of them.
4 ) Priority: Keep the default setting. You can change the
value if you want to first guarantee the bandwidth for
one computer. The smaller value has the higher priority.
5 ) Upstream/Downstream: Enter the bandwidth according
to your division.
6 ) Check to enable this entry and click OK to save the
settings.
6. Follow the steps above to add a rule for the other computer.
And then you will get the following table.

Network Security
This chapter guides you on how to protect your home network from unauthorized
users by implementing these three network security functions. You can block or allow
specific client devices to access your wireless network using MAC Filtering, or using
Access Control for wired and wireless networks, or you can prevent ARP spoofing and
ARP attacks using IP & MAC Binding.
• MAC Filtering
• Access Control
• IP & MAC Binding
Chapter 6
Network Security
6. 1. MAC Filtering
This function exploits the uniqueness of the MAC (Medium Access Control) address,
a unique 12-digit hexadecimal address (for example, D8:5D:4C:B4:46:EA) of every
network device, to determine if the device can or cannot access your wireless network.
I want to:
How can I
do that?
Prevent unauthorized users from accessing my wireless network
by utilizing the network device’s MAC address and IP address.
For example, I have a computer that is connected to my wireless
network. Now, an unknown device (an intruder) is also using my
wireless network, which affects my Internet speed. I would like
to control my wireless network with the following capabilities:
• My computer is always allowed to access the wireless network.
• The unknown device is not allowed to access the wireless
network.
• I don’t have to keep changing my wireless password as often.
1. Visit http://tplinkmodem.net, and log in with the password
you set for the router.
2. Go to Advanced >Wireless>MAC Filteringand enable
Wireless MAC Filtering.
3. Select the filtering rule to either block (recommended) or
allow the device(s) in the list.
24
Chapter 6
To block specific device(s)
1 ) Select Block wireless access from the devices in the list
below and click Save.
2 ) Select the device(s) to be blocked in the Devices Online
table.
3 ) Click Block above the Devices Online table. The selected
devices will be added to Devices List automatically.
To allow specific device(s)
1 ) Select Allow wireless access only from the devices in the
list below and click Save.
2 ) Click Add.
Network Security
3 ) Enter the MAC Address (You can copy and paste the MAC
Address from Devices Online list if the device is connected
to your wireless network) and enter the Description of
the device.
4 ) Select the checkbox to enable this entry, and click OK.
Done!
Now MAC Filtering is implemented to protect your wireless
network.
6. 2. Access Control
Access Control is used to block or allow specific client devices to access your network
(via wired or wireless) based on a list of blocked devices (Blacklist) or a list of allowed
devices (Whitelist).
I want to:
Block or allow specific client devices to access my network (via
wired or wireless).

How can I
do that?
1. Visit http://tplinkmodem.net, and log in with the password
you set for the router.
2. Go to Advanced >Security>Access Control and enable
Access Control.
3. Select the access mode to either block (recommended) or
allow the device(s) in the list.
To block specific device(s)
1 ) Select Blacklist and click Save.
2 ) Select the device(s) to be blocked in the Devices Online
table.
3 ) Click Block above the Devices Online table. The selected
devices will be added to Devices in Blacklist automatically.
