How to Limit Wi-Fi Speed: 5 Methods for Different Routers

In the age of unlimited data plans, throttling Wi-Fi speeds may seem like a strange solution. But in practice traffic control It becomes necessary in several situations: when children spend too much time playing online games, neighbors "borrow" your internet, or when you need to evenly distribute the bandwidth among a dozen smart devices. Without the right settings, one torrent on an old laptop can paralyze the entire home network—from Smart TV to IP cameras.

Modern routers offer flexible tools for limiting speed: from simple time limits to complex rules QoS (Quality of Service)However, the interfaces of different manufacturers differ greatly - what works on ASUS RT-AX88U, may not be available on budget TP-Link TL-WR840NIn this article, we'll explore universal methods and nuances for popular models, as well as explain how to bypass restrictions if your router doesn't support the features you need.

Before you begin setting up your settings, it's important to understand the key difference between the two types of restrictions: speed limit (for example, no more than 5 Mbps for a guest network) and traffic limit (For example, 10 GB per month for a child's smartphone). The first affects real-time speed, the second affects the total amount of downloaded data. Many routers can only handle one of these parameters, so choose the method based on your goals.

Another important point: restrictions at the router level only apply to devices connected to your networkIf someone uses mobile internet or a VPN, these rules won't apply. Full control may require a combination of router settings and specialized software on devices.

1. Preparation: What you need to know before setting up

Before limiting your Wi-Fi speed, there are a few essential steps you should take. First, check your current network load. To do this, connect your computer to the router via cable and run a speed test on websites like Speedtest.net or Yandex InternetometerWrite down the indicators—you'll need them to set the limits correctly.

Secondly, determine MAC addresses devices for which you want to impose restrictions. Find them in the router settings (section DHCP → Client List or Wireless Network → Connected Devices) or on the gadgets themselves:

• 📱 On Android: Settings → About phone → General information → Wi-Fi MAC address
• 🍎 On iPhone/iPad: Settings → General → About → Wi-Fi Address
• 💻 On Windows: run the command ipconfig /all V Command line and find the line "Physical Address"

The third step is to update your router firmware. Outdated firmware versions may not support speed limiting features or may work with errors. The update takes 5-10 minutes and is usually available in the "Updates" section. System → Software Update. After the update, all router settings will be reset to factory defaults—back up your configuration beforehand!

2. Speed ​​limiting via QoS (Quality of Service)

QoS — is a technology that allows you to prioritize network bandwidth among devices. For example, you can give them maximum speed. Smart TV for 4K streaming, while only allocating 2 Mbps to a child's smartphone. QoS settings are available on most modern routers, but the interfaces vary.

Let's look at the process using an example ASUS RT-AC68U:

1. Go to the control panel at the address 192.168.1.1 (login and password are usually admin/admin).
2. Let's go to the section Adaptive QoS → Bandwidth Configuration.
3. Let's turn it on Traditional QoS and indicate the actual speed of your Internet connection (10-15% lower than what the speed test shows).
4. In the section QoS rules we add a new rule, specify MAC address target device and limit the download/upload speed.

On routers TP-Link the path will be different: Advanced settings → QoS → Configure QoS rulesHere you can limit the speed for individual devices and for specific traffic types (for example, torrents or online games).

Find your actual internet speed|Find your devices' MAC addresses|Update your router's firmware|Back up your settings-->

An important caveat: QoS works more effectively when the overall network load is high. If the channel is only 30% loaded, the restrictions may not be effective. Also, some routers (especially budget ones) only support QoS for wired connections, not Wi-Fi.

What to do if QoS does not work?

If after configuring QoS the restrictions are not applied, check:

1) Are the MAC addresses specified correctly (they are case sensitive!)

2) Do the rules conflict with each other (for example, two rules for one device)

3) Does your router model support QoS for wireless clients?

4) Are the settings reset after reboot (a problem with some firmware versions)

3. Time limits (Parental Control)

If your goal is not so much to limit the speed, but to control the time of Internet access (for example, for children), use the function Parental control (Parental Control). It's available even on inexpensive routers and allows you to:

• 🕒 Set an access schedule (for example, the Internet is disabled from 8:00 PM to 8:00 AM)
• 📵 Block access to specific websites or types of content
• 📱 Limit your total online time per day

Setting up an example Keenetic:

1. Go to the web interface at the address my.keenetic.net.
2. Let's move on to Home Network → Parental Controls.
3. Add a new rule, select the device by MAC address or IP.
4. We specify the days of the week and time intervals when access will be blocked.
5. We apply the settings and test the operation on the target device.

On routers Xiaomi the path will be: Settings → Parental Controls → Add DeviceHere you can not only limit the time, but also set a daily traffic limit (for example, 1 GB per day).

⚠️ Note: The parental controls feature on some routers blocks access to the entire internet rather than limiting speed. If you need to throttle speed rather than completely disable access, use QoS.

4. Speed ​​limit for guest network

A separate guest network is a great way to restrict access for your devices and temporary guests. Most routers allow you to set up a guest network with a separate password and speed limits. This is especially useful for offices, cafes, or homes where visitors are often present.

Instructions for TP-Link Archer C6:

1. Let's go in Wireless Mode → Guest Access.
2. We enable the guest network, set its name (SSID) and password.
3. In the section Guest network settings we find the option Bandwidth limitation.
4. We specify the maximum download and upload speed (for example, 10 Mbps).
5. Save the settings and reboot the router.

On routers ASUS The guest network is configured in Wireless Network → Guest Access (AP Isolation)Here you can not only limit the speed, but also completely isolate guest devices from the main network (they won't see your shared folders or printers).

Please note: if you limit the guest network speed to 10 Mbps, and your main channel is 100 Mbps, then even if the guest network is fully loaded, the main devices will not experience any discomfort.

5. Alternative methods: when the router does not support restrictions

If your router doesn't have the ability to limit speed (for example, older models or devices from your ISP), there are several workarounds:

Method 1: Using a second router

Connect a second (cheaper) router to the main one and set up a separate network with restrictions on it. For example:

• 🔌 The main router distributes the Internet at maximum speed.
• 🔄 To the second router (for example, TP-Link TL-WR740N) connect the devices for which you need restrictions.
• ⚡ On the second router, configure QoS or time limits.

Method 2: Software restriction on the device

On computers with Windows 10/11 You can limit the speed through the Task Manager:

1. Open Start → Task Manager → Performance tab.
2. Right click on the network graph and select Set limit....
3. Specify a percentage of the maximum speed (e.g. 20% for 100 Mbps will give ~20 Mbps).

For Android applications like NetGuard or GlassWire, which allow you to limit the speed for individual applications. iOS There are no such opportunities without jailbreak.

Method 3: Contact your provider

Some internet service providers (eg. Rostelecom or Beeline) offer a "Home Control" service, which allows you to limit speed or access time through your personal account. Check with your carrier for available options.

⚠️ Note: Software restrictions on the device are easily circumvented—the user can simply disable the software or change the settings. For reliable control, it's best to combine several methods.

6. Checking and testing restrictions

After setting up restrictions, be sure to test them. Connect the target device to the network and follow these steps:

Step 1: Speed ​​Test

Run the test on the website Speedtest.net or via the app OoklaCompare your results with the established limits. Keep in mind that actual speed may vary by 10-15% due to protocol overhead.

Step 2: Stability Check

Leave the device connected for 10-15 minutes with an active load (for example, downloading a file). Make sure the speed doesn't drop over time or reset after rebooting the router.

Step 3: Test bypassing restrictions

Try connecting to the network from another device or changing the MAC address on the target device (for example, through an app) MAC Address Changer). If the restrictions are reset, it means the rules are tied only to the MAC and can be bypassed.

If the speed is not limited:

• 🔄 Reboot your router and check the settings again.
• 📋 Make sure the MAC address is entered correctly (no spaces and in the correct case).
• 🔧 Update your router firmware to the latest version.
• 📡 Check if QoS rules conflict with other features (e.g. IPTV or VPN).

7. Common mistakes and how to avoid them

When setting up restrictions, users often encounter common issues. Here are the most common ones and how to solve them:

Error 1: Restrictions do not apply to some devices

Reason: Many routers are unable to limit the speed of devices connected via WPS or through WDS-bridge. Solution: Disable these features or connect the problematic device via cable.

Error 2: Speed ​​"floats" or drops

Reason: QoS rules conflict with other services (eg. VoIP or UPnP). Solution: Disable unnecessary services in your router settings or move them to a separate, high-priority QoS queue.

Error 3: After updating the firmware, the settings were reset.

Cause: Some firmware versions reset custom QoS rules. Solution: Back up your configuration before updating and restore it afterward.

Error 4: Limitations only work for downloads, not uploads.

Reason: There is no limit on outgoing traffic specified in the QoS settings (Upload). Solution: Set up restrictions separately for Download And Upload.

Error 5: Devices connect, but the internet doesn't work

Cause: Overly strict restrictions (for example, a 1 Mbps limit for a device that requires 5 Mbps for stable operation). Solution: Increase the limits or check if parental controls are blocking access to DNS servers.

⚠️ Attention: On some routers (for example, Zyxel Keenetic) After changing QoS rules, a device reboot is required. Without it, the settings may not be applied.

FAQ: Answers to frequently asked questions

Is it possible to limit Wi-Fi speed without access to the router?

No, you must have access to the router's control panel to configure network-level restrictions. If you're not the network administrator (for example, in an office or dorm), contact the person who manages the router. An alternative is to use software restrictions on the device itself (see Section 5).

How to limit speed for a specific website or application?

Most home routers don't have the ability to limit speeds for specific websites. However, you can completely block access to them using parental controls or specialized solutions like Pi-hole (to block) or OpenWRT (for flexible traffic management). At the device level, this is suitable for these purposes. NetBalancer (Windows) or NetGuard (Android).

Why did my ping in games increase after I limited my speed?

Bandwidth limitation can increase latency (ping), especially if the limit is set too strict. For online gaming, connection stability is more critical than speed. We recommend:

• Set a limit of at least 10 Mbps for gaming devices.
• Use QoS with priority for gaming traffic (UDP port 3074 For PlayStation, 27000-27030 For Steam).
• Disable background downloads on other devices while playing.

Is it possible to limit the speed for devices on a neighboring router's network?

No, you can only control the traffic passing through your router. If your neighbors are using their own Wi-Fi, you won't be able to affect their speed. The exception is if you share your router with them (for example, by agreement), in which case you can restrict their devices' speeds based on MAC address.

How to reset all speed limits?

To delete all QoS or parental control rules:

1. Go to your router's control panel.
2. Go to the QoS/Parental Control settings section.
3. Delete all created rules or disable the feature completely.
4. Save the settings and reboot the router.

If you don’t remember what rules are set, you can do a full reset of the router to factory settings (button Reset on the back panel).
