Configure Router QoS

Configure D-Link Router QoS

You can easily configure your D-Link router to give priority to certain packets over others. This is called “traffic shaping,” meaning you are determining which packets have the right-of-way on your network. This is also know as Quality of Service (or QoS). Not all routers have this ability, but if your model does, you can configure D-Link QoSquickly if you know specifics about your computer’s settings. If your router doesn’t appear to have this ability, try downloading the latest firmware and try again, as this feature might have been added later.

How To Configure D-Link Quality of Service

You will need to know the IP addresses for each computer you want to assign QoS rules for. The easiest way to do this is to assign a range of IP addresses you know your router will use first. For example, if your D-Link router has an IP address of 192.168.0.1, then you know it will begin assigning IP addresses to computers beginning with 192.168.0.2. If you have game consoles, printers and other specialty devices, you may want to assign them static IP addresses above a specific range to make QoS easier to configure.
To enable QoS in your router, go to your web browser and type in http://192.168.0.1 and login with your username and password. You will find the QOS Engine under the advanced tab.
In the image below, we have configured a number 1 priority for a range of computers in our office. We have then given second priority to an Xbox game console. We gave the Xbox a static IP address so it would remain well above the number of PCs we had in the office. Since Internet and VoIP access are important to the PCs in the office, we gave them priority over the game console to preserve bandwidth and improve reliability.

It doesn’t matter how fast your Internet connection is. You should still consider setting up QoS on your router to give priority to some machines over others. While the above example is for a D-Link DIR-825 router, setting up Quality of Service on Linksys and other routers is a very similar process. It’s also important to write down all of your settings and any changes you make. If something goes wrong, you can always either revert the router back to factory defaults or use your notes to step the settings back.






How do I configure Bandwidth Control / IP-QoS on TP-LINK wireless router

Suitable for: 300Mbps Wireless N Routers, 150Mbps Wireless N Routers, 54Mbps Wireless G Routers
Why we need IP QoS (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 affects on the performance of the entire network. How can we avoid this?
The answer is IP QoS, which is designed to minimize the impact caused when the connection is under heavy load.  Using IP QoS, we can assign a specific minimum or maximum bandwidth for each computer, which means they have less impact on each other. Please follow the steps below to configure IP QoS.
How to configure IP QoS?
NOTE:
        You’d better set static IP Address on your local computers in order to manage easily. For how to configure TCP/IP properties on your computer,  please refer to this FAQ.
Step 1 Open the web browser and type the LAN address of the router in the address bar and then press Enter. The default IP address of TP-LINK router is 192.168.1.1. 
Step 2 Type the username and password in the login page, the default username and password of TP-LINK router are both admin in lowercase.
Step 3 Click QoS->QoS Settings on the left page and tick Enable QoS.  The Egress Bandwidth and Ingress Bandwidth should be the real bandwidth your ISP provides to you.
Egress Bandwidth-The upload stream through the WAN port.
Ingress Bandwidth-The download stream through the WAN port.
Step 4 Click Save to save the QoS Settings.
Step 5 Click QoS->QoS Rules List on the left page, you can view and configure the QoS rules.
Description-This is the information to describe the QoS rule.
Egress Bandwidth-This field displays the max and min upload stream through the WAN port.
Ingress Bandwidth-This field displays the max and min download stream through the WAN port.
Enable-This displays the status of the rules.
Modify-Click “Modify” to edit the rule.
Click “Delete” to delete the rule.
Step 6 Click Add New to add a new QoS 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 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.
Min Bandwidth-Assurable bandwidth,whenever,even though the traffic is very large in your network, as long as you have demand, it will support you assurable bandwidth at least.
Max Bandwidth-Limited bandwidth, when the network is idle, you can use idle bandwidth adequately, but it should be less than Max Bandwidth.
Step 7 Configure the QoS settings as per your real demand.
Note:
The amount of Min Egress Bandwidth and the amount of Min Ingress Bandwidth you configure should be less than Egress Bandwidth and Ingress Bandwidth you configure on QoS settingspage previously.
Example
If your connection is based on ADSL and your ISP provides 2Mbps downstream and 512K upstream, and you have 2 computers in network, you want each computer to have independent bandwidth for use, please configure IP QoS as the diagram below.
Egress Bandwidth and Ingress Bandwidth are real bandwidth upstream and downstream provided by your ISP.
Please configure the QoS Rule Settings for each computer as below:
Step 8 Click “Save” to save the settings you have configured.
