TP-Link: How to limit Wi-Fi speed for other users

Every wireless network owner is familiar with the experience of internet lag at the most inopportune moment. Often, the cause is simple channel congestion: a neighbor or family member has started downloading large files, playing online games, or watching 4K videos. In such cases, Speed ​​Limit becomes the only way to keep the network operational for important tasks.

The company's routers TP-Link Provide powerful traffic management tools that allow you to flexibly configure bandwidth for each connected device. You can completely block access to unwanted guests or simply throttle their bandwidth, preserving your own priority. This is especially relevant for small offices or apartments with numerous devices.

In this article we will discuss in detail how to set up Bandwidth Control and functions QoS in your router's interface. We'll cover both the classic green control panel and Tether's new blue interface, ensuring the instructions are useful for owners of all router models. Proper setup will help you become a fully-fledged administrator of your home network.

Preparing to set up the network and entering the interface

Before making any changes to your network configuration, you need to access your router's administrative panel. To do this, make sure your device (laptop or smartphone) is connected to the network. TP-Link Either via cable or WiFi. Open any browser and enter the gateway IP address in the address bar, which by default usually looks like this: 192.168.0.1 or 192.168.1.1.

After entering the address, the system will request authorization. If you have previously changed the default data, use your username and password. Otherwise, try the combination admin / admin, indicated on the sticker on the bottom of the device. It's important to understand that only users with administrator rights have access to these settings.

⚠️ Warning: If you change network settings while connected via WiFi, be prepared for the router to reboot or apply the rules immediately. Your device may lose connection during this time, so it's best to make critical changes from a computer connected via WiFi. LAN cable.

Interface of modern routers TP-Link may vary significantly depending on the firmware version. Devices with new firmware have a blue interface and are often controlled via a mobile app. Tether, while older models use the classic green design. The operating algorithm is similar, but the menu layout may vary.

Identifying devices on a local network

To limit the speed for a specific user, you first need to understand which device is consuming the traffic. In the router interface, go to the section Basic (Basic settings) and select the item Wireless or DHCP Server List. This displays a list of all clients currently connected to your access point.

Each device has a unique MAC address and a dynamically assigned IP address. The problem is that when reconnecting, the router may assign a new IP address to the device, and your speed limiting rules will no longer apply. To avoid this, you need to bind the IP address to the MAC address of a specific device.

• 📱 Find the unknown device in the list by name (for example, "iPhone-Ivan" or "Samsung-TV").
• 🔒 Write it down MAC address, consisting of six pairs of hexadecimal numbers.
• 📍 Reserve a permanent IP for it in the section Address Reservation or Static DHCP.

The procedure for reserving an address is as follows: in the menu Network -> DHCP Server -> Address Reservation click Add New. Enter the MAC address of the target device and the desired IP (e.g. 192.168.0.105). Save the settings. Now, even after rebooting the router, this device will always be assigned the same address, which is critical for setting up traffic rules.

Setting up Bandwidth Control on older interfaces

In classic green router interfaces TP-Link (TL-WR740N, TL-WR841N series and similar) the speed limit function is located in the section Bandwidth ControlThis is a powerful tool that allows you to set the minimum and maximum bandwidth for each IP address in both directions: Upload (recoil) and Download (loading).

The first step is to activate the control module itself by checking the box EnableNext, the system will ask you to specify your line type and overall channel speed. You should obtain this information from your provider or measure it yourself using speed testing services. Enter the maximum speed in kbps (1 Mbps = 1024 kbps).

After enabling general control, we proceed to creating rules. Click Add New and enter the IP address of the device that you reserved earlier. In the fields Max Bandwidth Specify the desired limit. For example, if you have a 100 Mbps plan and want to leave your neighbor only 2 Mbps, enter the Ingress Max field 2048.

⚠️ Important: Don't set the Min Bandwidth value to 0 if you want to guarantee at least some device performance. However, to fully prioritize your traffic, it's better to use the QoS feature rather than simply setting the minimum to zero.

Why is the speed in Kbps and not Mbps?

Router network settings often use the unit of measurement kbps (Kbps), while ISPs report speeds in Mbps (Mbps). To convert the value, multiply megabits by 1024. For example, 10 Mbps = 10240 Kbps.

Traffic management in the new interface and Tether

Owners of modern dual-band routers Archer and devices with a blue interface will find the speed limit function in the section Advanced -> QoS (Quality of Service). Here, the logic has been slightly modified: instead of a strict limit for each IP, the system allows traffic prioritization or limits for devices on the guest network.

To get started, enable the feature QoSYou'll be asked to select a priority task: gaming, video streaming, or web surfing. If you select "Gaming," the router will automatically prioritize packets with low ping, which is useful for gamers, but may not be helpful if someone is actively downloading files. A more flexible method is to use a guest network.

• 🔵 Go to the section Guest Network in the wireless network menu.
• 🚫 Activate the guest network and set a separate name and password for it.
• ⚙️ Some models have a speed limit slider in the guest network settings for all connected clients.

If your router supports the function HomeCare With Advanced Parental Controls, you can limit the speed for specific profiles. Create a "Guest" or "Kids" profile, link devices to it, and set a time or speed limit. This is the most streamlined method, requiring no complex bit-and-byte calculations.

Parental control as a tool of restriction

Function Parental Control in routers TP-Link Often underestimated, it's excellent for limiting the capabilities of connected devices. While its primary purpose is content filtering, it also allows for managing access time, which indirectly impacts network load.

In new firmware versions, parental controls are integrated with cloud services. TP-LinkYou may need to create an account. TP-Link ID and link the router to it. Then, using the smartphone app, you'll be able to see in real time how much traffic each device is consuming, and with just a swipe of a finger, you can pause it or restrict access to entertainment resources.

Parental control speed limits work on a priority basis. You can designate your device as the "Main" device and assign low priority to all other devices. During peak hours, when the channel is congested, the router will prioritize the requests of the Main device, effectively choking the speed of other users.

⚠️ Please note: Cloud parental control features depend on the manufacturer's servers. If the servers TP-Link are unavailable or there are connection issues in your region, app control may temporarily be unavailable, although the local network will continue to function.

To set up, go to Advanced -> Parental ControlsAdd a new device from the list of connected clients. Here you can set an access schedule. For example, allow internet access only from 6:00 PM to 8:00 PM. Outside these hours, the speed for this device will be virtually zero, as the connection will be disconnected.

Additional network security measures

Speed ​​limiting is a half-measure. If you notice someone using your WiFi, it's best to completely block their access. The most effective way is to change your wireless network password. Use a complex password with a combination of letters, numbers, and special characters to prevent brute-force attacks.

Enable MAC address filtering (Wireless MAC Filtering). This method allows you to create a "whitelist" of devices that are allowed to connect. All others, even with the password, will not be able to access the network. You can find this feature in the section Wireless -> Wireless MAC Filtering.

It is also worth checking if the function is enabled WPSThis is a simplified connection technology that often has vulnerabilities. Attackers can use special programs to brute-force the WPS PIN and gain access to your network. It is recommended to disable WPS in the wireless settings for increased security.

Is it possible to see what a user is doing on my network?

Using standard router tools, you'll only see the amount of traffic consumed and IP addresses. However, if the traffic is unencrypted (HTTP instead of HTTPS), it's theoretically possible to intercept the data, but this requires advanced skills and specialized software that goes beyond the router's default settings.

Frequently Asked Questions (FAQ)

Will the speed limit reset after rebooting the router?

No, all settings, including rules Bandwidth Control, QoS and IP address reservations are stored in the device's non-volatile memory. After a reboot, the router will automatically apply all previously set rules.

Why does the device still work fast after setting restrictions?

You may have specified the wrong unit of measurement (Kbps instead of Mbps), or the device may have changed its IP address, and the rule is being applied to a different device. Check whether the IP address is assigned to a MAC address and recalculate the limits by multiplying the megabits by 1024.

Is it possible to limit the speed for just one application, such as Torrent?

Using standard tools of a household router TP-Link This is difficult to do because they filter traffic by IP and port, not by program name. Deep traffic filtering (DPI) requires more complex systems or configuration on the client device itself.

Does WiFi speed limiting affect wired connection speed?

Rules Bandwidth Control Typically, these restrictions apply to all traffic passing through the specified IP address, regardless of the connection type (Wi-Fi or LAN). If you restrict a computer's IP, its speed will also drop over a cable connection.
