Why we need Bandwidth Control?

Within a normal home network, the bandwidth is shared by all computers. This means any computer using high-bandwidth applications, for example torrent programs or other P2P software, will affect the other computers. This may also include negative influence on the performance of the entire network. How can we avoid this?

The answer is Bandwidth Control, which is designed to minimize the impact caused when the connection is under heavy load. Using Bandwidth Control, we can assign a specific minimum or maximum bandwidth for each computer, which means they have less interference on each other. Please follow the steps below to configure this feature.

How to configure Bandwidth Control?

The scenario below will take 3 computers sharing 512Kbps Egress Bandwidth and 4Mbps Ingress Bandwidth as an example, and explain how to use Bandwidth Control to optimize the load respectively.

Scenario:

Example:①PC1 often plays online game and downloads files which uses the most part of bandwidth.

②PC2 is used for watching movies on the Internet which also needs much bandwidth.

③PC3 is used for browsing websites usually, so it only needs a few bandwidth.

Please log in to the web management interface to setup bandwidth control.

Step 1

Open the web browser and in the address bar type in the default access like:: http://tplinkwifi.net

Note:

Please find the default access on the bottom label of the product.

Step 2

Type the username and password in the login page. The default username and password are both admin in lower case.

Step 3

Click on Bandwidth Control-Control Settings on the left menu.

Note:

For example, if you have a ADSL Modem, please choose “ADSL” 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.

The Egress Bandwidth and Ingress Bandwidth should be the real bandwidth given by your ISP. (1Mbps=1024Kbps)

Step 4

Click Save to save the Settings.

Step 5

Click Bandwidth Control -> Rules List on the left page, you can view and configure the rules.

Step 6

Click Add New to add a new rule.

IP Range-Single IP address or IP address Range. 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.

Port Range-The port arrange of TCP protocol or UDP protocol.

Protocol-You can choose the TCP protocol or UDP protocol or both of them.

Egress Bandwidth - The max and the min upload speed which through the WAN port, default number is 0.

Ingress Bandwidth - The max and the min download speed through the WAN port, default number is 0.

NOTE:

You’d better set static IP Address on your local computers or configure Address reservation on the wireless router in order to manage easily.

Step 7

According to the demand of clients, the bandwidth could be allocated as following.

From the rules, the max Bandwidth can ensure that PC1 and PC2 can take up all bandwidth when it’s alone to access the Internet and the min Bandwidth can ensure that they have the necessary bandwidth when more than one PC work at the same time.

Note: The amount of Min Egress Bandwidth and Min Ingress Bandwidth you configure should be less than Egress Bandwidth and Ingress Bandwidth you configure on Bandwidth Control settings page previously.

Step 8

Enable the Bandwidth Control and click the Save button on Bandwidth Control Settings to take effect.
