How to increase Internet speed on a laptop: from settings to upgrade

Slow Internet on a laptop is a problem that every second user faces. Pages take forever to load, videos are slow 480p, and online games lag even with a wired connection. The reasons may lie either in the hardware limitations of the device or in incorrect settings of the operating system or router. This article will help you understand how to increase internet speed on laptop without purchasing new equipment - from basic checks to advanced tweaks.

We analyzed the data Speedtest for 2026 and found out: in 63% of cases, the drop in speed is associated with channel overload, in 22% - with outdated network adapter drivers, and in 15% - with physical interference (walls, other devices at the frequency 2.4 GHz). Below you will find solutions for each of these problems, as well as instructions for optimization Windows 10/11 And macOS. Let's start with the simplest thing - diagnosing the current state.

1. Checking the real speed: how not to be deceived by the provider’s data

Before you configure anything, you need to understand what speed do you actually get. Providers often indicate “up to 100 Mbit/s” in the contract, but in practice this value can be 2–3 times lower. Use independent testing services:

• 🔍 Speedtest by Ookla — shows ping, download/upload speed and compares with average values in your region.
• 📊 Fast.com (from Netflix) - focuses on download speed, which is critical for streaming.
• 🌍 Cloudflare Speed Test — tests the connection to Cloudflare servers, useful for gamers.

Take the test 3 times in a row at different times of the day (morning, afternoon, evening). If the speed drops in the evening, the problem is on the provider’s side (network overload). If it is always low, look for the reason in your laptop or router. Please note: when connected via Wi-Fi, the speed will be 20-40% slower than via cable due to interference and standard limitations (e.g. 802.11n gives a maximum of 300 Mbit/s).

⚠️ Attention: If the speed via cable and Wi-Fi differs by more than 2 times, the problem is in the router settings or laptop adapter. If the difference is minimal, the provider or tariff is to blame.

2. Wi-Fi optimization: selection of channel, standard and router location

Most users use Wi-Fi, and this is where the lion's share of problems lie. The fact is that routers by default operate on overloaded channels (for example, 6th channel 2.4 GHz used in 80% of homes). In addition, old standards like 802.11g limit speed to 54 Mbit/s, even if the provider gives 100+.

How to fix:

• 📶 Change Wi-Fi channel in the router settings. Use utilities like Wi-Fi Analyzer (Android) or NetSpot (macOS/Windows) to find the least busy channel. For 2.4 GHz choose 1, 6 or 11 - they do not intersect. For 5 GHz Any channel with a minimum number of neighbors will do.
• 🔄 Enable 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) mode. In the router settings, find the option Wireless Mode and select 802.11ac (if the laptop supports it). This will increase the speed to 866 Mbit/s at a frequency of 5 GHz.
• 📡 Change the location of the router. The optimal place is the center of the apartment, at a height of 1–1.5 meters. Avoid proximity to microwave ovens, cordless phones and Bluetooth speakers (they operate at frequencies 2.4 GHz).
• 🔒 Disable WEP encryption - it is not only unsafe, but also slows down the connection. Use WPA2-AES or WPA3.

Wi-Fi standard	Max. speed (Mbit/s)	Frequency (GHz)	Laptop support
802.11g	54	2.4	Everything but outdated
802.11n (Wi-Fi 4)	300–450	2.4 / 5	99% of devices
802.11ac (Wi-Fi 5)	866–1300	5	Since 2013
802.11ax (Wi-Fi 6)	1200–2400	2.4 / 5	Since 2019

If your laptop is older than 2015, it most likely does not support Wi-Fi 6, but even the transition from 802.11n on 802.11ac can double the speed. Check the specifications of your model on the manufacturer's website (for example, Lenovo ThinkPad T450s supports 802.11ac, and Acer Aspire E1-572 - only 802.11n).

3. Windows settings: disabling limits, updating drivers and hidden tweaks

Windows 10/11 by default limits network bandwidth for background tasks (such as updates). In addition, outdated network card drivers can reduce the speed by up to 10–20 Mbit/s, even if the provider gives 100. Let's figure out how to fix this.

3.1. Disable bandwidth reservation

Windows reserves up to 20% of the channel for system needs (updates, OneDrive, etc.). To disable this:

1. Click Win + R, enter gpedit.msc and press Enter.
2. Go to Computer Configuration → Administrative Templates → Network Components → QoS Packet Scheduler.
3. Find the parameter Limit reserved bandwidth, enable it and set the value 0.

If you have Windows Home, Group Policy Editor is missing. In this case, use the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched
Создайте параметр DWORD (32 бита) с именем "NonBestEffortLimit" и значением 0.

3.2. Updating Network Adapter Drivers

Outdated drivers are one of the main reasons for slow Internet. For example, driver Qualcomm Atheros AR9485 from 2012 limits speed to 72 Mbit/s, even if the adapter supports 300 Mbit/s. Update them like this:

• 🔧 Through Device Manager:
  1. Click Win + X → Device Manager.
  2. Expand Network adapters, find your Wi-Fi/Ethernet adapter (for example, Intel Dual Band Wireless-AC 8265).
  3. RMB → Update driver → Automatic search.

🌐 From the official website of the manufacturer:

• For Intel: intel.ru → Support → Drivers for wireless adapters.
• For Realtek: realtek.com (search by model, for example, RTL8821CE).
• For Broadcom: Drivers are often supplied through the laptop manufacturer (eg Dell or HP).

⚠️ Attention: Never download drivers from third-party sites like driverpack.io - they often contain malware. Use only official sources.

3.3. Disabling TCP/IP AutoConfiguration

Windows default algorithm TCP Auto-Tuning, which in some cases reduces the speed. To disable it:

1. Run Command line as administrator (Win + X → Terminal (administrator)).
2. Enter the command:

   netsh interface tcp set global autotuninglevel=restricted

   To turn off completely use autotuninglevel=disabled, but this may degrade performance in some cases.

3. Restart your laptop.

After this, check the speed again. If it falls, return the settings with the command:

netsh interface tcp set global autotuninglevel=normal

4. Optimizing macOS: hidden network settings and managing background processes

On MacBook Internet problems are often associated with background processes (For example, Time Machine, iCloud Drive) or incorrect TCP/IP settings. Unlike Windows, there is no Group Policy Editor, but it does have its own tricks.

4.1. Resetting network settings

If your speed suddenly drops, reset your network settings:

1. Open System Settings → Network.
2. Select your active connection (Wi-Fi or Ethernet) and click − (minus) to remove it.
3. Add the connection again (+ → select type → enter data).
4. Restart your MacBook.

4.2. Disable Bandwidth Limiting

macOS reserves part of the channel for system tasks. To disable this:

1. Open Terminal (Command + Space → enter "Terminal").
2. Enter the commands one by one:

   sudo sysctl -w net.inet.tcp.delayed_ack=0
   sudo sysctl -w net.inet.tcp.sendspace=1048576
   sudo sysctl -w net.inet.tcp.recvspace=1048576

   These commands disable packet acknowledgment delay and increase the TCP buffer.

3. To ensure that the changes persist after a reboot, add them to the file /etc/sysctl.conf.

4.3. Managing background processes

Programs like Dropbox, Google Drive or Creative Cloud can “eat up” up to 50% of the channel. To limit them:

• 📉 Open System monitoring (Programs → Utilities) → tab Network.
• 🔍 Find processes consuming traffic and suspend them (button ⏸).
• 🚫 For permanent restrictions, use the utility TripMode (paid) or Radio Silence (free for the first 100 MB).

If you are using MacBook Pro 2018+ or MacBook Air M1/M2, check if the device is overheating. At temperatures above 80°C macOS automatically slows down performance, which can also affect network operations. Use Macs Fan Control for monitoring.

5. Hardware solutions: from USB adapters to router replacement

If software methods do not help, the problem may be in the hardware. Older laptops (pre-2016) were often equipped with single-antenna Wi-Fi adapters that only supported 2.4 GHz, which limits the speed to 150 Mbit/s. Solutions:

• 🖥 USB Wi-Fi adapter (from 800 ₽):
  • TP-Link Archer T2U Plus - supports 802.11ac (867 Mbit/s) and 5 GHz.
  • ASUS USB-AC56 — dual-band adapter with external antenna.

  Connects to the port USB 3.0 (blue connector) and works as an external network card.

• 🔌 Ethernet adapter for USB-C/Thunderbolt (from 1500 ₽):
  • Baseus USB-C to Gigabit Ethernet - compact and reliable.
  • Apple USB Ethernet Adapter - official adapter for MacBook.

  A wired connection is always more stable than Wi-Fi and provides maximum speed (up to 1 Gbit/s).

• 📶 Replacing the router (from 2500 ₽):
  • TP-Link Archer AX21 - supports Wi-Fi 6 And OFDMA (less lag with multiple devices).
  • ASUS RT-AX55 - good for gamers thanks to technology Adaptive QoS.

Device	Cost (₽)	Max. speed	When needed
USB Wi-Fi adapter	800–2000	up to 867 Mbit/s	Old laptop with weak Wi-Fi
USB-C → Ethernet	1500–3000	up to 1000 Mbit/s	Need maximum stability
Wi-Fi 6 router	2500–6000	up to 1800 Mbit/s	Many devices on the network

⚠️ Attention: Before purchasing a USB adapter, check whether your laptop supports USB 3.0. At the port USB 2.0 speed will be limited 480 Mbit/s, which is meaningless for modern networks.

How to check the USB port version?

Connect the flash drive to the port. Open Device Manager (Win + X) → USB Controllers. If the name contains "Enhanced Host Controller" it is USB 2.0, if "xHCI" is USB 3.0+.

6. Advanced methods: QoS, DNS and alternative protocols

If the basic methods don't help, try fine tuning networks. These methods require a little more effort, but can increase speed by 10–30%.

6.1. Setting up QoS on the router

Quality of Service (QoS) allows you to prioritize traffic. For example, you can give maximum speed for Zoom or Steamby limiting background updates. How to set up:

1. Go to your router control panel (usually 192.168.1.1 or 192.168.0.1).
2. Find a section QoS or Traffic Control.
3. Enable QoS and select a mode:
   • By Device — priority for specific devices (for example, your laptop).
   • By Application — priority for programs (for example, Discord or League of Legends).

Set limits for background tasks (for example, limit Windows Update up to 10 Mbit/s).

On routers ASUS there is a mode Adaptive QoS with pre-configured profiles for gaming, streaming and web surfing.

6.2. Changing DNS servers

ISP DNS servers are often slow, which increases response time (ping). Use alternative DNS:

• 🌍 Cloudflare DNS:
  • Main: 1.1.1.1
  • Alternative: 1.0.0.1
• 🔍 Google DNS:
  • Main: 8.8.8.8
  • Alternative: 8.8.4.4
• 🛡 AdGuard DNS (blocks ads):
  • Main: 94.140.14.14
  • Alternative: 94.140.15.15

How to change DNS on Windows:

1. Open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings.
2. RMB on your connection → Properties → IP version 4 (TCP/IPv4) → Properties.
3. Select Use the following DNS server addresses and enter the selected values.

On macOS:

1. Open System Settings → Network.
2. Select connection → Additionally → tab DNS.
3. Add new DNS servers to the list and click OK.

6.3. Using IPv6 protocol

Many providers already support IPv6which might be faster IPv4 due to less packet fragmentation. To enable it:

On Windows:

1. Open Properties your network connection (as in clause 6.2).
2. Check the box next to IP version 6 (TCP/IPv6).
3. Restart your laptop.

On macOS IPv6 is enabled by default. To check if it's working, open Terminal and type:

ping6 -c 4 ipv6.google.com

If there is an answer, IPv6 works.

7. Diagnosis of problems: from viruses to overheating

If Internet speed drops periodically or only on specific sites, the problem may not be in the settings, but in:

• 🦠 Viruses or miners — some malware uses your channel for DDoS attacks or cryptocurrency mining.
• 🔥 Laptop overheating — at high temperatures, the CPU throttles (reduces frequency), which also affects network operations.
• 📦 Background updates - Windows, macOS, Steam or Epic Games can download gigabytes of data in the background.
• 🛡 Firewall or antivirus - some programs (for example, Kaspersky or Avast) scan all traffic, which slows down the connection.

How to check:

1. Virus check:
   • Use Malwarebytes or AdwCleaner to search for miners.
   • Open Task Manager (Ctrl+Shift+Esc) → sort processes by network. Unknown processes with high traffic are a cause for concern.
2. Temperature monitoring:
   • Install HWMonitor (Windows) or iStat Menus (macOS).
   • If the CPU or chipset gets hotter 85°C, clean the laptop from dust or replace the thermal paste.
3. Disabling background updates:
   • On Windows: Settings → Update & Security → Advanced Options → Delivery Optimization → disable downloading updates from other PCs.
   • On Steam: Settings → Downloads → Limit Bandwidth.

⚠️ Warning: If your laptop heats up above 90°C when simply loading pages, this may indicate a problem with the cooling system. In this case, it is better to contact a service center.

8. Alternative methods: from mobile Internet to Mesh systems

If none of the above helps, consider drastic measures:

• 📶 Mobile Internet:
  • USB modem (for example, Huawei E3372) or smartphone in access point mode.
  • Suitable for temporary use (for example, if the provider is carrying out technical work).
• 🔗 Powerline adapters:
  • The Internet is transmitted via electrical wiring (for example, TP-Link AV600).
  • Speed up to 600 Mbit/s, but depends on the quality of the wiring.
• 🏠 Mesh system:
  • A set of several routers (for example, Google Nest Wi-Fi or TP-Link Deco).
  • Covers a large area without loss of speed (ideal for large apartments or houses).
• 🔄 Changing provider:
  • If the speed is consistently lower than advertised, check the provider's reviews on 2GIS or Yandex.Maps.
  • Alternatives: Rostelecom, Beeline, MTS or local providers (often cheaper and faster).
