Why we need Bandwidth Command?
Within a normal home network, the bandwidth is shared past all computers. This means any computer using high-bandwidth applications, for instance torrent programs or other P2P software, will touch on the other computers. This may besides include negative influence on the performance of the entire network. How can we avoid this?
The answer isBandwidth Control, which is designed to minimize the affect acquired 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 take less interference on each other. Please follow the steps below to configure this feature.
How to configure Bandwidth Control?
The scenario below will accept 3 computers sharing 512KbpsEgress Bandwidth and 4MbpsIngress Bandwidth as an example, and explicate how to use Bandwidth Control to optimize the load respectively.
Scenario:
Example: ① PC1 often plays online game and downloads files which uses the virtually function of bandwidth.
② PC2 is used for watching movies on the Internet which as well needs much bandwidth.
③ PC3 is used for browsing websites usually, and then it simply needs a few bandwidth.
Delight log in to the spider web direction interface to setup bandwidth control.
Footstep ane
Open the web browser and in the address bar type in the default access like : :http://tplinkwifi.internet 
Note:
Please observe the default access on the lesser characterization of the production.
Step 2
Type the username and password in the login page. The default username and password are bothadminin lower case.

Note:
For example, if you accept a ADSL Modem, please cull "ADSL" on the line type. If you don't know how to choose theLine Blazon, please contact your Isp which line type you have access.
TheEgress BandwidthandIngress Bandwidth should be the existent bandwidth given by your ISP . ( 1Mbps=1024Kbps )
Step 4
ClickSaveto salvage the Settings .
Footstep v
ClickBandwidth Control -> Rules Listingon the left page, y'all tin can view and configure the rules .
Step 6
Click Add New to add together a new rule. 
IP Range- Single IP address or IP address Range. When you configure the single IP accost, the computer with this IP address will get contained given bandwidth. When you configure the IP address range, all computers in the range willshare the given bandwidth.
Port Range- The port arrange of TCP protocol or UDP protocol.
Protocol- You tin 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.
Annotation:
Yous'd better set static IP Address on your local computers or configure Accost reservation on the wireless router in order to manage easily.
About how to configure TCP/IP backdrop on your computer, delight refer to FAQ fourteen
Almost how to configure Accost Reservation, delight refer to FAQ 182
Step 7
Co-ordinate 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 upwards all bandwidth when information technology'southward alone to access the Cyberspace and the min Bandwidth can ensure that they take the necessary bandwidth when more than one PC piece of work at the aforementioned time.
Note: The amount ofMin Egress Bandwidth and Min Ingress Bandwidth you configure should exist less than Egress Bandwidth andIngress Bandwidth you configure onBandwidth Control settings page previously.
Step 8
Enable the Bandwidth Control and click the Salve button onBandwidth Control Settings to have effect.
