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 by 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 4Mbps 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. The IP addresses of our computers 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 it 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.
4. Choose your Line Type.
5. Enter the Total Upstream Bandwidth and Total Downstream
Bandwidth given by your ISP (1Mbps=1024kbps). Click Save
to save the settings.
6. Click Add to add a controlling rule.

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.

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 by using IP & MAC Binding.

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.
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 Filtering and enable
Wireless MAC Filtering.

3. Select the filtering rule to either block (recommended) or allow the device(s) in the list.
To block/allow specific device(s)
1 ) Select Block wireless access from the devices in the list
below or Allow wireless access only from the devices in the list below and click Save.
2 ) Click Add.

3 ) Enter the MAC Address manually. (You can copy and
paste the information from Devices Online table if the device is connected to your network).
4 ) Enter the Description of the device.
5 ) Select the check box 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:
How can I do that?
Block or allow specific client devices to access my network (via wired or wireless).
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.

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.
To allow specific device(s)
1 ) Select Whitelist and click Save.
2 ) Click Add.

3 ) Enter the Device Name and MAC Address (You can copy
and paste the information from Devices Online table if the device is connected to your network).
4 ) Click OK.
Network Security
Done!
Now you can block or allow specific client devices to access your network (via wired or wireless) using the Blacklist or Whitelist.

6. 3. IP & MAC Binding

IP & MAC Binding, namely, ARP (Address Resolution Protocol) Binding, is used to bind network device’s IP address to its MAC address. This will prevent ARP spoofing and other ARP attacks by denying network access to a device with matching IP address in the Binding list, but unrecognized MAC address.
I want to:
How can I do that?
Prevent ARP spoofing and ARP attacks.
1. Visit http://tplinkmodem.net, and log in with the password you set for the router.
2. Go to Advanced > Security > IP & MAC Binding and enable IP
& MAC Binding.
3. Bind your device(s) according to your needs.
To bind the connected device(s)
1 ) Select the device(s) to be bound in the ARP List.
25

Network Security
2 ) Click Bind to add to the Binding List.
To bind the unconnected device
1 ) Click Add.
2 ) Enter the MAC address and IP address that you want to
bind.
Done!
3 ) Select the check box to enable the entry and click OK.
Now you don’t need to worry about ARP spoofing and ARP attacks.
