How To Set Bandwidth Limit in Windows 11 (5 Ways)

The frequency at which a bandwidth-intensive device (a server) receives data or the speed (in B/KBps) of each data response is limited (throttled) by bandwidth throttling. If these constraints are not in place, the device’s processing capacity may be exceeded.

When assessing the price for new consumers, services like Netflix and Hulu considers how their users utilize bandwidth. Although this is inconvenient for customers, it makes sense from a company’s standpoint since using a limitless amount of bandwidth would raise acquisition costs, infrastructure expenses, and so on. These businesses are attempting to price their services such that the number of customers does not exceed the available bandwidth, which would degrade the user experience.

It seems that you don’t want to waste your internet data by consuming excessive bandwidth on your computer. Once you set a specific bandwidth for your computer, the internet data usage measured by your device and service provider may differ.

By the end of this article, you’ll be able to set bandwidth limit for applications in Windows 11:

Many companies such as Cisco, NetGear, and TP-Link offer built-in network monitoring and throttling features that you can use to manage bandwidth on your network without configuring the Windows default settings. Depending on your needs you can limit bandwidth for all connected devices or specific devices on the network. Simply check on Google whether or not your router supports the network management and monitoring features.

Tool 1: T-Meter

T-Meter is a tool used to monitor network traffic, bandwidth, data transfer between server and client, window domain authentication, traffic shaping (speed control), traffic reports, packet filtering, DNS Server forwarding, built-in DHCP (Dynamic Host Configuration Protocol) Server, etc.
Type: Freeware

Tool 2: Net Peeker

Net Peeker is tested and compatible with Windows 11. The main features include network traffic monitoring, desktop-based firewall, network speed limitation, traffic shaping (speed control), malware protection, network traffic analysis, network traffic capture, stored logs, etc.

Next Steps

We’ve covered how to set bandwidth limit in Windows 11. Depending on your requirements, you can use any one of the methods listed above.

If you’re restricting bandwidth to improve download and upload speeds, several other aspects are taken into account, including packets received and delivered, compatibility of your computer’s hardware and router, network congestion, and your ISP’s backend infrastructure, among others. So, even after liming the bandwidth, you cannot be fully assured that your internet will work faster in terms of downloading and uploading.
