Bandwidth Control

Just quoting the comment of a reader on a previous post

Hi Sir,
I have BSNL Broadband connection and a Fujian starnet S4U+ V.1 modem,i share my connection with my room mate,he is connected on Lan4 port mine is Lan1,he is taking a lot of bandwidth,so how can I set QOS? traffic limitation for Lan4 (him)
please help.

You might have also faced the similar problem. Unfortunately normal routers don’t facilitate flexible bandwidth control. Here TP Link TD –W8968 is the winner. Through the Bandwidth control option, you can very easily and flexibly allocate bandwidth for each client machines. Two settings are available under Bandwidth Control Menu- Control Settings and Rules Lists. See the screenshots

bandwidth control

Enable the Bandwidth Control option under Control settings menu to turn ON this feature. Set the Line type to ADSL  and enter the total upstream and downstream bandwidth in kbps. This settings will limit the overall upstream and downstream bandwidth from/to your modem. For example if your maximum downstream speed is  8 Mbs multiply this with 1024 to get the bandwidth in Kbps which will be  8192 Kbps.

Select the Rules List menu to view and configure the bandwidth control (See the above image). Click the Add New button for making a new rule. In the page You can enter the IP range and minimum/maximum upstream/downstream bandwidth. For example if you want to restrict the bandwidth of a particular machine. Get the IP of that machine and enter the IP address in both the fields of IP Range.

Remember: If you enable DHCP , this setting won’t be effective because under DHCP, the clients will be allotted IP addresses dynamically. Hence for effective bandwidth control Disable DHCP .  You can change the DHCP settings through DHCP Server Menu options. Under DHCP settings – Select the option “Disable DHCP Server”. Now you have to configure the network adaptors of client machines. Router will not provide IP to client machines automatically.

You can also use MAC binding option to reserve an IP address exclusively for a particular machine . For that Select the IP and MAC Binding Menu. A page displays the IP and MAC binding table. You can delete, add and edit the entries. See the screenshot .

Get the mac address of your PC/Laptop and map with the desired IP Address.
