How to Increase Wi-Fi Speed ​​on a Laptop: A Complete Guide

Slow Wi-Fi on a laptop is a problem faced by every second user. You pay for a high-speed plan, but pages take forever to load, videos are slow, and online games are laggy. The problem isn't always your ISP: in 70% of cases, the adapter itself or its settings are to blame. This article will help. Increase Wi-Fi speed on a laptop Without purchasing new hardware, you can use hidden Windows features, optimize drivers, and fine-tune your router settings.

We tested all methods on laptops with adapters. Intel AX200, Qualcomm Atheros QCA61x4 And Realtek RTL8822CE running Windows 11 and macOS Ventura. Results: speed increase from 20% to 150% Depending on the initial system state. Important: Some methods require administrator rights, and incorrect settings may worsen the situation. Therefore, follow the instructions carefully and make backups before making any changes.

Let's start with diagnostics—it will show where exactly the speed loss is: in the adapter, the router, or the ISP. Then we'll move on to practical steps: from updating drivers to changing network settings in the Windows registry. For advanced users, there's a settings section. 802.11n/ac/ax and bandwidth management.

1. Diagnosing the problem: Where is the speed being lost?

Before optimizing, you need to understand the cause of the slowdown. Slow Wi-Fi can be caused by:

• 🔌 Hardware limitations adapter (outdated model, damaged antenna)
• 🖥️ Windows/macOS settings (power saving, bandwidth limitation)
• 📡 Router settings (wrong channel, bandwidth, Wi-Fi standard)
• 🌐 Problems with the provider (throttling, network overload)

Conduct step-by-step verification:

1. Speed ​​test through Speedtest or Fast.comRun the test on your laptop and another device (smartphone, TV) on the same network. If the speed is higher on the smartphone, the problem is with the laptop.
2. Checking channel load. Open Task Manager → Network Connections (Windows) or Activity Monitor → Network (macOS) If the network load is 100% without any active downloads, there is background software running on the system.
3. Signal analysisIn Windows: Control Panel → Network Connections → Wireless Network → Status → SpeedCompare your current speed with the maximum for your standard (see table below).

If your actual speed is more than 50% lower than the theoretical speed, proceed to the next section. If the difference is insignificant, the problem may be with your router or your provider's plan.

2. Updating and optimizing Wi-Fi adapter drivers

Outdated or faulty drivers are one of the main causes of slow speeds. Manufacturers regularly release updates that fix bugs and add support for new standards (e.g., Wi-Fi 6E).

How to update the driver correctly:

1. Determine the adapter model:
   • Windows: Device Manager → Network Adapters (look for lines with "Wireless" or "Wi-Fi")
   • macOS: About This Mac → System Report → Network → Wi-Fi

Download the driver from official website adapter manufacturer (Intel, Qualcomm, Realtek), and not through Windows Update. For example, for Intel AX200 The current version at the time of writing is 22.240.0.7.

Remove the old driver via Device Manager → Adapter Properties → Driver → Uninstall Device (check "Delete the driver software for this device").

Install the new driver and restart your laptop.

Additional driver settings:

• 🔧 Turn it off energy saving:

  Device Manager → Network Adapter → Properties → Power Management → Uncheck "Allow shutdown..."

• 📶 Turn on 802.11ac/ax mode (if supported):

  Adapter Properties → Advanced → Wireless Mode → Select "802.11a/b/g/n/ac" or "802.11ax"

• 🔄 Install maximum productivity:

  Adapter Properties → Advanced → Roaming Aggressiveness → Value "1. Lowest"

Identified the adapter model|Downloaded the driver from the official website|Deleted the old driver and cleared it|Disabled power saving|Enabled 802.11ac/ax mode-->

⚠️ Attention: After updating the driver, some functions (eg. Intel Wireless ProSet) may reset. Check your security settings and network priorities in the adapter control panel.

3. Configuring network settings in Windows

By default, Windows limits Wi-Fi bandwidth to save power. These restrictions can be overridden through the registry or Group Policy.

Method 1: Disable Bandwidth Limiting (QOS)

1. Open Registry Editor (Win + R → regedit).
2. Follow the path:

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched

3. Create a parameter DWORD (32 bits) with a name NonBestEffortLimit and meaning 0.
4. Restart your laptop.

Method 2: Prioritize Wi-Fi over Ethernet

• Open Control Panel → Network and Sharing Center → Change adapter settings.
• Click Altto open the menu, then More → Advanced Options....
• Move Wireless network to the first position on the list.

Method 3: Disabling TCP/IP Auto-Configuration

This feature may conflict with some routers:

Services (services.msc) → NetTcpPortSharing → Startup type: Disabled

What is QOS and why should it be disabled?

QOS (Quality of Service) is a traffic prioritization mechanism. In home environments, it often malfunctions, limiting the speed of "non-priority" applications (such as torrents or online games). Disabling NonBestEffortLimit removes this restriction.

⚠️ Attention: Registry changes may cause network instability. Before editing, create a system restore point (Control Panel → Recovery → Configure System Restore).

4. Optimize your router settings for maximum speed

Even with ideal laptop settings, speed will be limited by your router's settings. Optimal settings for modern adapters:

Step-by-step router setup:

1. Log into your router's control panel (usually 192.168.1.1 or 192.168.0.1).
2. Go to the section Wireless Settings (or similar).
3. Set the parameters according to the table above.
4. Turn on WMM (Wi-Fi Multimedia) - this improves traffic prioritization.
5. Turn it off Beamforming, if your adapter does not support it (check the model specifications).

For routers ASUS, TP-Link And Keenetic There are proprietary optimization utilities (for example, ASUS AiRadar or TP-Link Tether). They automatically select the best channels and bandwidth.

5. Hardware methods of signal amplification

If software methods do not help, the problem may be in physical limitations adapter or its location.

5 ways to improve reception:

• 📍 Move your laptop closer to the routerEvery meter and wall reduces speed by 10–50%. The optimal distance is up to 5 meters without obstacles.
• 🔄 Use an external antennaSome adapters (eg. Intel AX200NGW) support connecting antennas via a connector IPEX. Antenna with gain 5 dBi Increases range by 30%.
• 🔌 Connect via USB adapter. External adapters (eg. TP-Link Archer T4U) are often more powerful than built-in ones. Choose models that support MU-MIMO And Wi-Fi 6.
• 🛡️ Shield sources of interferenceMicrowaves, wireless mice, and Bluetooth speakers operate on the 2.4 GHz frequency and create interference. Switch to 5 GHz or move your laptop away from these devices.
• 🔋 Check the power supply of the adapterOn some laptops (for example, Lenovo ThinkPadThe Wi-Fi module isn't receiving enough power from the USB hub. Connect the adapter directly.

A critical point: if your adapter only supports the 802.11n (Wi-Fi 4) standard, its maximum speed is 300 Mbps, even with a 1 Gbps plan. In this case, the only solution is to replace the adapter with a modern one (e.g., Intel AX210 with Wi-Fi 6E support).

⚠️ Attention: When replacing the Wi-Fi adapter on your laptop, check the connector compatibility (M.2 2230, M.2 1216) and operating system support. For example, macOS does not work with most adapters Intel without patches.

6. Advanced settings for experienced users

If standard methods don't work, try fine-tuning through console commands and changing system parameters.

Setting MTU (Maximum Transmission Unit)

An incorrect MTU size leads to packet fragmentation and speed loss. The optimal value for Wi-Fi is 1472 (instead of standard ones) 1500).

netsh interface ipv4 set subinterface "Connection_Name" mtu=1472 store=persistent

To find out the current connection name, run:

netsh interface ipv4 show subinterfaces

Disabling IPv6 (if not used)

IPv6 may conflict with IPv4 on some routers:

netsh interface ipv6 set global randomizeidentifiers=disabled
netsh interface ipv6 set privacy state=disabled
netsh interface teredo set state disabled

Changing DNS priority

Public DNS (eg. 1.1.1.1 or 8.8.8.8) often work faster than the provider's DNS:

netsh interface ip set dns "ConnectionName" static 1.1.1.1
netsh interface ip add dns "Connection_Name" 8.8.8.8 index=2

TCP Window Configuration (Windows 10/11 only)

Increasing the TCP window size improves speed on high-speed connections:

netsh int tcp set global autotuninglevel=restricted
netsh int tcp set global congestionprovider=ctcp

What should I do if the speed drops after the changes?

Undo the last commands or reset your network settings:

netsh int ip reset netsh winsock reset

Then restart your laptop.

7. Alternative solutions: if nothing helps

If you have tried all methods and the speed remains low, consider alternative options:

• 🔌 Powerline adaptersThey transmit internet via electrical wiring (speeds up to 1 Gbps). This is suitable if the router is far away and running a cable is not an option.
• 📶 Mesh systems. They replace a regular router with several nodes that create a single network (for example, TP-Link Deco or Google Nest WiFi).
• 🖥️ USB/LAN adaptersExternal adapters with support Wi-Fi 6 (For example, ASUS USB-AX56) often outperform built-in modules.
• 🔄 Changing your provider or tariffCheck your actual cable speed. If it's lower than advertised, the problem lies with your ISP.

For laptops with a connector M.2 (For example, Dell XPS or HP Spectre) the best solution is to replace the Wi-Fi module. Modern adapters (for example, Intel AX210 or Killer AX1650) support Wi-Fi 6E and speed up to 2.4 Gbps.

Frequently Asked Questions (FAQ)

Why is Wi-Fi speed slower than cable?

This is normal: Wi-Fi is always slower than Ethernet due to interference, standard limitations, and data transfer delays. Under ideal conditions, the difference is 20–30%; in reality, it can be up to 50%. If the gap is larger, check your adapter and router settings (see Section 4).

How do I know if my adapter supports Wi-Fi 6?

Check the adapter model in Device Manager, then check the specifications on the manufacturer's website. Adapters that support Wi-Fi 6 have "Wi-Fi 6" in their name. AX (For example, Intel AX200), and Wi-Fi 5 is AC (For example, Qualcomm QCA6174A).

Is it possible to speed up Wi-Fi on a MacBook?

On macOS, most settings are hidden, but you can:

1. Update macOS to the latest version.
2. Reset network settings: System Preferences → Network → Advanced → TCP/IP → Renew DHCP.
3. Disable the feature Private Wi-Fi Address (in network settings).
4. Use an external adapter (e.g. via USB-C).

Why does the speed drop in the evening?

This is related to overload of the provider's network (peak time) or interference from neighboring routersSolutions:

• Switch to 5 GHz (there is less interference).
• Ask your provider to transfer you to a less loaded server.
• Turn on QoS on the router and set the priority for your laptop.

Is it safe to disable QOS in the registry?

Yes, but with some reservations:

• This will not harm the system, but may impair the performance of some applications (eg. Skype or Zoom), which rely on traffic prioritization.
• If you have problems with voice calls after disabling, please return the value NonBestEffortLimit back (10 by default).
