How to reduce Wi-Fi speed for others on a router

Many people are familiar with the situation when the internet becomes unstable just when you urgently need to download an important file or conduct a video conference. Often, the cause is a family member playing a demanding game or 4K video on the TV while you're trying to work. In such cases, it becomes urgent to adjust your network settings to prioritize your traffic or even limit the capabilities of other devices.

Fortunately, modern routers Provides extensive tools for managing bandwidth. You don't need to be a system administrator or have in-depth knowledge of network protocols to configure basic speed limiting settings. Simply access your device's web interface and find the relevant sections, which may have different names depending on the hardware model.

In this article, we'll take a detailed look at the main methods for artificially throttling speeds for unwanted traffic consumers or simply distributing resources fairly. We'll cover both standard parental control and QoS features, as well as more advanced filtering techniques. MAC addresses and manual setting of limits.

Enter the router settings and find the required sections

The first step to any network manipulation is logging into the device's administrative panel. To do this, open any browser on a computer or smartphone connected to the router and enter the gateway IP address in the address bar. These are typically standard values, such as 192.168.0.1 or 192.168.1.1, which are often indicated on a sticker on the bottom of the case.

After entering your login and password (which are often the default ones) admin (or also indicated on the sticker) you will be taken to the main menu. Interfaces from different manufacturers, such as TP-Link, Keenetic, ASUS or MikroTik, may differ dramatically visually, but the menu structure remains similar. You need to find sections related to the wireless network, traffic, or clients.

⚠️ Attention: If you have changed the password for the admin panel earlier and have forgotten it, you will have to reset the router to factory settings using the button ResetThis will result in the loss of all current provider and Wi-Fi settings.

Look for tabs labeled "Bandwidth Control," "Traffic Manager," "QoS" (Quality of Service), or "Parental Control." These sections contain speed management tools. Some budget models may have limited functionality, requiring you to use workarounds, which we'll discuss below.

Using QoS to prioritize traffic

Technology QoS (Quality of Service) is the most civilized and effective way to manage traffic. Instead of completely blocking someone, this feature allows the router to automatically prioritize. You can configure the system so that your computer always receives the maximum speed, while other devices make do with the remaining bandwidth.

To activate this feature, go to the corresponding section of the menu. Here, you'll need to enable the QoS mechanism and enter your actual internet speed, as provided by your provider. This is a critical parameter: if you enter a speed lower than your actual speed, the router will artificially limit everyone's bandwidth, and if you enter a speed higher than your actual speed, the algorithms won't work correctly.

Next, you need to configure priority rules. The following levels are typically available:

• 🥇 Highest — for your work PC or laptop.
• 🥈 High — for set-top boxes or Smart TV.
• 🥉 Normal — for ordinary users.
• 📉 Lowest — for background downloads or guest devices.

Once the settings are applied, the router will begin analyzing data packets and redistributing them according to the specified rules. This prevents a situation where one user completely hogs the channel, leaving others without network access.

Speed ​​limiting via Bandwidth Control

A more strict method that allows you to set specific limits in kilobits or megabits per second is the function Bandwidth ControlUnlike QoS, which works with priorities, here you set strict limits for each connected device. This is ideal if you want to ensure that neighbors or children don't download more than a certain amount of data.

In the Bandwidth Management menu, you'll need to create new rules. For each rule, you'll need to specify an IP address range (or a specific address) and incoming speed limits (Ingress) and to the exit (Egress). It's important to understand the difference: incoming speed is the speed at which a device downloads data from the internet, while outgoing speed is the speed at which it sends data.

Let's look at an approximate table of settings for a typical home network:

After filling in the fields, be sure to check the "Enable" box and save the settings by clicking the "Save" button. Changes take effect immediately, but some devices may require a reconnection to the Wi-Fi network for the new limits to apply.

MAC address filtering and device blocking

If soft speed limiting methods don't produce the desired result or the router interface doesn't support flexible limit settings, you can resort to more drastic measures. Filtering by MAC addresses Allows you to completely block network access for certain devices or, conversely, allow access only to selected ones.

Each network device has a unique identifier - a MAC address. Finding it in the client list (Client List or Wireless Statistics) the device that's consuming too much traffic, you can copy its address. Next, in the "Wireless MAC Filtering" section, create a blocking rule.

There are two filtration modes:

• 🚫 Deny (Prohibit) — devices from the list will not be able to connect to Wi-Fi, all others work freely.
• ✅ Allow — only devices from the white list will be able to connect to the network; the rest will be rejected by the router.

⚠️ Caution: Be careful when using "Allow" mode. If you add only one device to the list and then lose access to the router, you won't be able to connect to it from other devices to change settings.

This method is effective if you want to completely disable the "disturber." However, it doesn't solve the speed distribution problem if the goal is to keep the device running, albeit slowly.

How to find out the MAC address of someone else's device?

The router's client list often displays not only IP addresses but also device names (e.g., iPhone-Ivan). If the name isn't clear, you can look up the MAC address in the device's settings (in the "About Phone" or "Status" section) and compare it with the router's data.

Setting up a guest network as an alternative

Modern routers such as Keenetic or ASUS, often have a guest network feature. This is a separate access point with its own username and password. The idea is to transfer all "problem" users to the guest profile, which has strict restrictions by default.

In the guest network settings you can:

• 📶 Limit the maximum speed for the entire guest area.
• 🕒 Set time limits for access (for example, only during the day).
• 🔒 Isolate clients from each other so they can't see your shared folders.

This is the most elegant solution for an apartment with neighbors or frequent guests. You give them the password for the guest Wi-Fi, which is limited to 1-2 Mbps—sufficient for messaging apps, but not enough for watching high-quality video. Your main connection remains free.

To set it up, find the "Guest Network" section, enable it, set a name (SSID), and find the speed limit slider in the advanced settings. This will allow you to control the situation without interfering with other users.

Frequently asked questions and issues when setting up restrictions

During setup, users often encounter nuances that can be confusing. For example, after applying the settings, the speed doesn't change. This may be because the device received a new IP address via DHCP, and the rule is bound to the old address. In such cases, it is recommended to configure static IP binding (Address Reservation) for each device.

Another common issue is the impact of encryption. Some older traffic throttling methods don't work well with modern WPA3 encryption protocols. If you're using the latest security standards, try temporarily switching to WPA2 to test the throttling rules.

Is it possible to limit the speed without logging into the router?

Without access to the router's admin panel, it's impossible to limit the speed of other users. However, you can use firewall software on your computer to prioritize your traffic, but this won't affect the speed of other devices on the network.

Will the router reset its settings after turning it off?

No, all settings saved via the "Save" or "Apply" buttons are saved to the device's non-volatile memory. They will remain intact even after a complete power outage or router reboot.

Why is the speed of a limited device still high?

Check whether the device is using a proxy server or VPN. Also, make sure the restriction rule is applied to the correct interface (Wi-Fi, not LAN) and traffic direction (Upstream/Downstream).

Does speed limiting affect ping in games?

Yes, proper use of QoS significantly reduces ping (latency) because game packets are prioritized over file download or video streaming packets, even if the channel is fully loaded.

Do I need to reboot my router after setup?

In most cases, changes are applied immediately. However, if you've changed wireless or security settings, the router may require a reboot for the new configuration to take effect.

What should I do if my router freezes after setup?

If your router stops responding after making QoS changes, perform a hard reset by holding the Reset button for 10-15 seconds. This will restore factory settings and restore access.
