How to remove Wi-Fi speed limits: from your provider, router, and system

Have you noticed that your internet speed via cable is much faster than via Wi-Fi? Or has the usual boost disappeared after connecting a new device to the network? The reasons may lie beyond a weak signal or channel congestion. Speed ​​is often artificially limited. providers, router firmware or even operating systems — and this can be fixed without purchasing new equipment.

In this article we will analyze all possible “brakes”: from hidden tariff limits to incorrect QoS settings in your router. You'll learn how to check for restrictions, bypass them legally, and restore maximum speed without risking your equipment. And if the problem lies in hardware limitations, we'll advise you when it's time to consider replacing your router or switching to a different Wi-Fi standard (for example, from 802.11n on 802.11ac/ax).

Spoiler: in 60% of cases, changing just one or two settings in the router's admin panel or network card drivers is enough. Let's start with the simplest thing—diagnostics.

1. How to understand that Wi-Fi speed is really limited

Before changing anything, make sure the problem isn't due to objective factors such as distance from the router, interference from neighboring networks, or outdated equipment. three tests:

• 📊 Compare cable and Wi-Fi speeds on one device. Connect your laptop or PC directly to the router via Ethernet and measure the speed on Speedtest or FAST.comIf the difference exceeds 30%, there is definitely a limit.
• 🔄 Check the speed on different devicesIf on a smartphone iPhone 13 speed 50 Mbps, and on the old one Samsung Galaxy A5 2017 — 10 Mbps, the problem is in the phone hardware, not the network.
• 🕒 Measure your speed at different times of the dayProviders sometimes throttle (slow down) traffic during peak hours (in the evening). If the speed is higher during the day, it's an artificial limitation.

If all three tests show anomalies, proceed to the next section. If the speed via cable and Wi-Fi is equally low, the problem is with your provider (contact support) or your plan (perhaps you have "night unlimited" with daily restrictions).

2. ISP restrictions: how to check and bypass them

Some internet providers artificially limit Wi-Fi speed for tariffs marked "up to X Mbps", where "up to" refers to the theoretical maximum, not the guaranteed speed. This most often applies to mobile operators (for example, MTS, Beeline, Tele2) and small local providers.

How to find out if your ISP is at fault:

1. Check your contract or personal account on the provider's website. Look for phrases like "maximum wireless speed" or Wi-Fi traffic limitation.
2. Call support and ask directly: "Do I have a speed limit on 802.11 (Wi-Fi)?"Sometimes operators honestly admit, "Yes, you have a tariff with a 50 Mbps over-the-air limit."
3. Use a VPN. If you connect to a VPN (for example, ProtonVPN or Windscribe) the speed increases - the provider slows down certain types of traffic (for example, torrents or videos).

If the restriction is confirmed, the options are as follows:

• 💰 Change your tariff for a more expensive one without Wi-Fi restrictions (check with your provider).
• 🔌 Connect via cable - Some providers do not limit wired connections.
• 🌐 Use a VPN (but this may reduce speed due to encryption).
• 📡 Buy a 4G/5G router with an unlimited tariff from another operator (relevant for regions with poor wired internet).

3. Router settings: where to look for hidden speed limits

Even if the ISP isn't at fault, the limitation may be embedded in the router's settings. Most often, this is:

• QoS (Quality of Service) — traffic prioritization, which can “choke” the speed for some devices.
• Bandwidth Control — manual speed limitation by MAC addresses or IP.
• Wi-Fi operating mode - if the router is configured to 802.11b/g instead of 802.11n/ac/ax, the speed will be below maximum.

Instructions for popular router models:

If your router doesn't have QoS, check Bandwidth Control or Traffic ControlFor example, in TP-Link it could be in Advanced → Network → Bandwidth ControlMake sure there are no rules with your IP or MAC address.

How to find the MAC address of a device?

On Windows: Open a command prompt (Win + R → cmd) and enter ipconfig /all. Look for the line Physical Address next to your Wi-Fi adapter.

On Android: Settings → About phone → General information → Wi-Fi MAC address.

On iPhone: Settings → Wi-Fi → (i) next to the network → MAC address.

4. Updating the firmware and resetting the router settings

Outdated router firmware can not only limit speed but also create security vulnerabilities. Updating often resolves these issues. Wi-Fi drivers, routing algorithms And compatibility with new devices.

How to update firmware:

1. Find out the router model (written on the sticker at the bottom).
2. Download the latest firmware from the manufacturer's official website (for example, for TP-Link — tp-link.com, For ASUS — asus.com).
3. Log into your router's admin panel (usually at 192.168.0.1 or 192.168.1.1).
4. Find the section Administration, System Tools or Software update.
5. Upload the downloaded file and wait until it is completed (do not turn off the router!).

If the speed has not increased after the update, do the following: reset to factory settings:

• 🔧 Click the button Reset on the back panel of the router (hold for 10-15 seconds).
• 🖥️ Or find it in your admin panel System Tools → Factory Defaults.

After resetting, configure the router again (create a new password for Wi-Fi and check if QoS is enabled by default!).

5. Wi-Fi settings on devices: Windows, Android, macOS

Sometimes the speed limit isn't inherent in the router, but in the device itself—due to outdated drivers, incorrect adapter settings, or power-saving features. Let's look at this step-by-step for each operating system.

Windows 10/11

Open device Manager (Win + X → Device Manager) and find the section Network adapters. Right-click on your Wi-Fi adapter (for example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA61x4) and select Properties → AdvancedCheck the following parameters:

• 🔄 Roaming Aggressiveness — put it Lowest or Medium (a high value results in frequent reconnections and a drop in speed).
• 📶 Wireless Mode — choose 802.11ac or 802.11ax (if the adapter supports it).
• 🔋 Transmit Power — install Highest (if the parameter is available).
• 🚫 802.11n/ac Wireless Mode — it should be Enabled.

If the adapter driver is older than 2020, update it through the manufacturer's official website (not through Windows Update!). For example, for adapters Intel download the driver from intel.com, For Realtek - With realtek.com.

Android

On smartphones, Wi-Fi speed may be limited due to:

• 🔋 Power saving mode - turn it off in Settings → Battery → Power saving mode.
• 📱 Developer settings — turn it on Do not turn off data transfer And Aggressive Wi-Fi switching (path: Settings → About phone → Build number (tap 7 times) → Developer options).
• 🗑️ Wi-Fi cache - delete the network and reconnect (Settings → Wi-Fi → (tap on the network) → Delete).

macOS

On Mac, check:

• 🔍 System Preferences → Network → Wi-Fi → Advanced → TCP/IP Settings - make sure that Configure IPv6 is in mode Automatically.
• 🔄 System Preferences → Energy Saver - uncheck Enable power saving mode when running on battery power.

6. Hardware limitations: when it's time to change your router or adapter

If you have tried all the methods, but the Wi-Fi speed still has not increased to the level of a wired connection, the problem may be in hardware limitations:

• 📡 Wi-Fi standard: the router or adapter only works 802.11n (maximum 300-450 Mbps), not 802.11ac (up to 1.3 Gbps) or 802.11ax (up to 10 Gbit/s).
• 📶 Frequency 2.4 GHz: if the router does not support 5 GHz, the speed will be limited by interference from neighboring networks.
• 🔌 WAN/LAN port 100 Mbps: Older routers have ports limited to 100 Mbps, even if Wi-Fi is theoretically faster.
• 🔋 Chip overheating: If the router is hot, it may automatically reduce the transmission power.

How to check:

1. Check the router's specifications on the sticker or in the instructions. Look for supported standards (802.11ac/ax) and frequencies (2.4 GHz / 5 GHz).
2. Check the ports: if next to the Ethernet connector it says 10/100, and not 10/100/1000 — the port is limited to 100 Mbit/s.
3. Connect the router to a different internet connection (for example, via a 4G modem). If the Wi-Fi speed is still low, the problem is with the router.

If your router is outdated, consider models that support:

• 🚀 Wi-Fi 6 (802.11ax) — for speeds above 1 Gbps.
• 📶 Dual-band mode (2.4 + 5 GHz) - to reduce interference.
• 🔌 Gigabit Ethernet ports (10/100/1000).
• 🛡️ MU-MIMO support — for stable operation of several devices.

7. Alternative methods: Mesh systems, repeaters, and Powerline

If replacing your router isn't an option and your Wi-Fi speed is critically low, consider alternative solutions:

• 📶 Mesh system (For example, Google Nest Wi-Fi or TP-Link Deco) - covers a large area without loss of speed.
• 🔄 Wi-Fi repeater — enhances the signal, but can reduce the speed by 30–50%.
• ⚡ Powerline adapters (For example, TP-Link AV1000) — transmit the Internet via electrical wiring (speed up to 1 Gbit/s).
• 📡 4G/5G router — If your wired internet is slow, connect via a mobile network (relevant for country houses).

Mesh systems are the best option for large apartments or houses. They automatically switch devices between access points, avoiding connection drops. Repeaters are cheaper but create a separate network, which can cause latency.

Powerline adapters are suitable if you have thick walls that interfere with the Wi-Fi signal. They work through a wall outlet and provide a stable connection, but are sensitive to the quality of the electrical wiring.

FAQ: Frequently asked questions about Wi-Fi speed limiting

Can a provider limit the speed only on Wi-Fi, but not on cable?

Yes, some providers (especially mobile operators) list speeds of "up to X Mbps" in their plans, but stipulate that Wi-Fi speeds may be lower. This is specified in the contract under "Access Technology Restrictions." To find out for sure, call support or check your personal account.

Why did my speed become even slower after updating my router firmware?

Possible reasons:

1. The new firmware has reset your QoS or Bandwidth Control settings - please check them again.
2. The firmware contains bugs (especially if it is a beta version) - roll back to the previous version.
3. Wireless network settings have changed (e.g. channel width) - please reset 40 MHz for 2.4 GHz or 80 MHz for 5 GHz.

How do I know if my router supports Wi-Fi 6 (802.11ax)?

Look at the sticker on the back of your router or in the instructions. Look for the following:

• Wi-Fi 6, 802.11ax, AX1800/AX3000 etc.
• Dual-Band or Tri-Band (support 2.4 + 5 GHz).
• MU-MIMO, OFDMA — technologies characteristic of Wi-Fi 6.

If there is nothing like this, your router is operating according to the old standard (802.11n or 802.11ac).

Is it true that a VPN can increase Wi-Fi speed?

Yes, but only in one case: if your ISP is artificially throttling certain types of traffic (for example, torrents or 4K video). A VPN encrypts your traffic, so your ISP can't detect what you're downloading—so no restrictions apply. However:

• ⚠️ Speed ​​can fell, if the VPN server is far away or overloaded.
• ⚠️ Not all VPNs offer high speeds - choose services that support WireGuard or OpenVPN UDP.
• ⚠️ The provider may block popular VPNs (for example, many servers are blocked in Russia) NordVPN And ExpressVPN).

Is it worth buying a router with Wi-Fi 6E support?

Wi-Fi 6E supports additional range 6 GHz, which is less busy than 2.4 GHz And 5 GHzThis is relevant if:

• Do you have many devices (10+) simultaneously connected to the network.
• You are using VR/AR helmets, 4K video streaming or online games with low ping.
• Your The provider provides speeds above 1 Gbps.

For a typical apartment with 3-5 devices and speeds up to 300 Mbps, Wi-Fi 6 is enough (802.11ax) without 6 GHz support.

If none of the methods helped, the problem may be physical interference (walls, furniture, neighboring networks) or equipment malfunctionsIn this case, contact a specialist to diagnose the line or replace the cables (especially if they are damaged or older than 10 years).
