Have you noticed that your internet is slowing down because one device is hogging all your bandwidth? Or do you want to evenly distribute the speed among family members so that video calls aren't interrupted by movie downloads? Speed limiting by Wi-Fi solves these problems, but many users do not know how to set it up correctly.
In this article you will find step-by-step instructions for popular brands of routers (TP-Link, ASUS, Keenetic, MikroTik), as well as universal methods that work on most models. We'll look at how to limit the speed for both all devices, and for individual gadgets — whether it's a smartphone, smart TV, or gaming console. You'll also learn which Hidden settings may reset your restrictions after rebooting your router. and how to avoid it.
Why should you limit your Wi-Fi speed?
Without traffic control, one device can clog up the channel, leaving other network users with only a fraction of the advertised speed. For example:
- 🎮 Game consoles (PlayStation 5, Xbox Series X) when downloading updates, they can take up to 90% of the channel.
- 📱 Smartphones with background synchronization of cloud services (Google Photos, iCloud) quietly “eat up” traffic.
- 🖥️ Computers with torrent clients or streaming in
4Kcreate peak loads.
Speed limits help:
- 📶 Distribute the Internet evenly among all devices.
- 🛡️ Protect yourself from "traffic attacks" from your neighbors (if you have a weak password).
- 💰 Save on mobile internet if your router is distributing
4G/5G.
⚠️ Attention: On some routers (Zyxel Keenetic, Tenda) speed limitation only works for devices connected via Wi-Fi. Devices with cable connection (LAN) can bypass these limits.
Method 1: Restriction via the router's web interface (universal method)
Most modern routers allow you to configure speed limits through the admin panel. The general algorithm is:
- Connect to the router via
Wi-Fior cable. - Open your browser and enter the router's IP address (usually
192.168.0.1or192.168.1.1). - Enter your login and password (by default it is often
admin/admin). - Find the section
QoS(Quality of Service),Bandwidth ControlorBandwidth management.
Further steps depend on your router model. Below are details for popular brands.
☑️ Preparing to configure QoS
Method 2: Configuring QoS on TP-Link routers
On routers TP-Link (For example, Archer C6, TL-WR841N) the speed limit is configured through the section QoS. Follow the instructions:
- Go to
Advanced Settings → QoS → QoS Settings. - Turn on
QoSand select the typeBy IP/MAC. - Please specify maximum outgoing (
Upload) And incoming (Download) speed for the device. - Add a rule for a specific
IPorMAC addresses(you can find it in the sectionDHCP).
An example of a limitation for a smartphone with MAC address 00:1A:2B:3C:4D:5E:
Rule name: Limit_PhoneMAC address: 00:1A:2B:3C:4D:5E
Max. incoming: 10 Mbps
Max. outgoing: 5 Mbps
| Router model | QoS section | Does it support MAC restriction? |
|---|---|---|
| TP-Link Archer C6 | Additional settings → QoS |
Yes |
| TP-Link TL-WR841N | QoS → Rules List |
No (IP only) |
| TP-Link Deco M5 | More → QoS |
Yes (via app) |
⚠️ Attention: On some firmware versions TP-Link After the update the rules are resetQoSBefore updating, export the settings to a file (System Tools → Backup).
Method 3: Speed limiting on ASUS routers
Routers ASUS (For example, RT-AX88U, RT-AC68U) offer flexible settings QoS through the section Adaptive QoSHere's how it works:
- Go to
Adaptive QoS → Bandwidth. - Select type
Traditional QoS(for manual tuning). - Please specify the overall speed of your internet (For example,
100 Mbpsincoming and50 Mbpsoutgoing). - In the section
QoS rulesadd a new rule for the device byIPorMAC.
Peculiarity ASUS: you can ask here traffic prioritiesFor example, give maximum speed to video calls (Zoom, Skype) and limit torrents.
How to check your real internet speed?
To properly configure QoS, first measure your actual connection speed without restrictions. To do this:
1. Connect your computer to the router with a cable.
2. Open Speedtest.net (or similar service).
3. Run the test and record the values Download And Upload.
4. In the QoS settings, specify 10-15% less than these values (for example, if the test showed 90 Mbps, set 80 Mbps).
Method 4: Keenetic – limitation via “Bandwidth Control”
Routers Zyxel Keenetic (For example, Keenetic Giga, Keenetic Extra) use a different approach. Here, the speed limit is configured in the section Bandwidth control:
- Open the web interface and go to
Internet → Bandwidth Control. - Enable the option
Limit download/upload speed. - Add a rule for the device by specifying it
IPorMAC. - Set limits in the fields
Max download speedAndMax upload speed.
An important nuance: On Keenetic You can limit the speed for individual devices as well as for entire groups (for example, all smartphones or all TVs). To do this:
- Create a group in the section
Home Network → Devices. - Apply the rule
QoSto the whole group.
⚠️ Attention: On routers Keenetic with firmware below3.6There may be no support for the limitationMAC addressUpdate the firmware viaSystem → Update.
Method 5: MikroTik – Advanced Settings via Winbox
Routers MikroTik (For example, hAP ac², RB4011) require more in-depth knowledge but offer maximum flexibility. To limit speed:
- Connect to the router via Winbox (you can download it at official website).
- Go to
IP → Firewalland create a new rule. - On the tab
Advancedplease indicateDst. Address(IP devices) and limit the speed throughLimit.
Example command to restrict a device with IP 192.168.88.100 to 5 Mbps:
/ip firewall mangle add chain=forward dst-address=192.168.88.100 action=limit-dst-limit limit-dst=5M/5M
For MikroTik Also available:
- 📊 Traffic usage charts in real time (
Tools → Graphing). - 🔄 Dynamic speed distribution depending on network load.
Common mistakes and how to avoid them
Even experienced users sometimes encounter problems when setting speed limits. Here are the most common errors:
- 🔌 The overall internet speed is incorrect. - if in
QoSIf you set more than the provider allows, the rules will not work. - 🔄 Resetting settings after reboot - on some routers (Tenda, old D-Link) rules
QoSare not saved. Solution: update the firmware. - 📱 IP restriction instead of MAC - if the device receives
IPByDHCP, it may change and the rule will stop working.
How to check if the restriction is working?
- Connect the device for which the limit is configured.
- Run a speed test on Speedtest.net.
- Compare the result with the values specified in the settings.
⚠️ Attention: On some routers (Mercusys, Totolink) the speed limit only works forWi-Fi, but not forLANIf the device is connected via a cable, the limits will be bypassed.
FAQ: Answers to frequently asked questions
Is it possible to limit the speed only on a laptop, but not on a phone?
Yes, you can do that in the settings. QoS add a rule only for MAC addresses or IP laptop. Make sure the devices are different MAC (You can see them in the list of connected router clients).
Why is the speed not limited after setting up QoS?
Possible reasons:
- The overall internet speed is incorrectly specified in the settings.
QoS. - The rule is applied to the wrong one
IP/MAC. - The device is connected via cable (
LAN), and the restriction only works forWi-Fi. - It's enabled on the router.
Turbo ModeorGame Mode, which cancelsQoS.
Check each item and reboot the router.
How to limit speed for a guest network?
On most routers (ASUS, TP-Link, Keenetic) The guest network is configured separately. Its settings usually include a field Maximum speed or Bandwidth LimitFor example, on Keenetic:
- Go to
Home Network → Guest Network. - Enable guest network and set speed limit.
- Save the settings.
Is it possible to limit the speed on routers from a provider (Rostelecom, Beeline, MTS)?
Yes, but with some reservations:
- 🔹 Routers Rostelecom (Sagemcom, Sercomm) usually have limited functionality. Try the section
QoSorTraffic management. - 🔹 U Beeline And MTS routers are often installed Huawei or ZTE - in them the speed limit is hidden in
Advanced → Traffic Control. - 🔹 If the interface is blocked, contact your provider's support team and ask them to unblock the settings.
How to completely disable speed limiting?
To remove all limits:
- Go to the section
QoS(or similar). - Disable the option
Enable QoS(orEnable Bandwidth Control). - Delete all created rules.
- Save the settings and reboot the router.
If the speed is not restored after this, check whether the Parental Control or other traffic control functions.
