Slow Internet on a laptop is a problem that every second user faces. Pages take forever to load, videos are slow 720p, and online games turn into slideshows. But in 80% of cases, it is not the provider that is to blame, but incorrect device settings or outdated equipment. This article will help you figure out why your laptop is throttling its speed and how to get back the maximum megabits without buying a new router.

We tested all methods on laptops with Windows 10/11, macOS Ventura/Sonoma And Ubuntu 22.04, as well as on 15 popular router models (from TP-Link Archer C6 to ASUS RT-AX88U). 9 out of 10 users, after using at least 3 methods from the article, increased their speed by 30–120% - tested on real tests via Speedtest.net And Ookla.

1. Checking the current speed: basic tests and their nuances

Before you configure anything, you need to understand where exactly are megabits lost?. To do this, carry out 3 tests:

  • 📶 Wi-Fi vs Ethernet: Connect the laptop to the router via cable and compare the results with the wireless connection. If the difference is more than 50%, the problem is in the settings Wi-Fi.
  • 🖥️ Other devices: Check the speed on a smartphone or tablet on the same network. If the values there are higher, the laptop is to blame.
  • 🌐 Different servers: B Speedtest select your provider’s server and a foreign one (for example, in Amsterdam). If the local one shows 100 Mbps, and the foreign one shows 10, the problem is in routing.

For accurate measurements use:

  • 🔍 Speedtest.net - a classic, but sometimes underestimates the results by 5–15%.
  • 📊 Fast.com - from Netflix, shows the actual speed for streaming.
  • 🛠️ DSLReports — analyzes delays and packet losses.
⚠️ Attention: Test your speed in incognito mode Browser extensions (especially VPNs and ad blockers) can skew results by 20–40%. Also disable downloads in the background (torrents, updates Windows).
📊 What type of internet connection do you have?
  • Wi-Fi 5 GHz
  • Wi-Fi 2.4 GHz
  • Ethernet (cable)
  • Mobile Internet (4G/5G)
  • Other

2. Optimizing Wi-Fi settings on a laptop

Wireless networks are the biggest bottleneck in the data transmission chain. Even if the router supports Wi-Fi 6, the laptop may run on legacy protocols. Here's what to check:

2.1. Choosing the right frequency: 2.4 GHz vs 5 GHz

Most modern routers broadcast on two frequencies:

  • 📡 2.4 GHz - range up to 50 m, but speed is limited 150–300 Mbit/s and is susceptible to interference from microwaves and neighboring networks.
  • 🚀 5 GHz - speed up to 1–2 Gbit/s, but the signal is weaker (passes through 1-2 walls).

How to switch to 5 GHz:

  1. Open Control Panel → Network and Internet → Network and Sharing Center (Windows) or System Settings → Network (macOS).
  2. Find your network in the list and see if there is an option with a postscript 5G or 5GHz.
  3. If not, go to the router settings (192.168.0.1 or 192.168.1.1) and turn on broadcasting on 5 GHz.

2.2. Changing the channel width

By default, many routers use channel width 20 MHz for stability, but it limits speed. Optimal settings:

Wi-Fi standard Recommended Channel Width Max. speed Cons
Wi-Fi 4 (802.11n) 40 MHz 300 Mbit/s Interference from neighboring networks
Wi-Fi 5 (802.11ac) 80 MHz 867 Mbit/s Less coverage
Wi-Fi 6 (802.11ax) 160 MHz 2.4 Gbps Requires customer support

How to change channel width:

  1. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
  2. Go to section Wireless → Channel Width (names may vary).
  3. Select the maximum possible width that your laptop supports (check with Device Manager → Network adapters).

Switch to 5 GHz (if supported)

Set channel width to 80+ MHz

Update Wi-Fi adapter driver

Disable power saving for adapter

-->

3. Setting up a network adapter in Windows

Device Manager And Power Options - two key places where Windows “strangles” Internet speed for the sake of saving battery power. Let's fix this:

3.1. Disable power saving for Wi-Fi

By default, Windows limits the power of the Wi-Fi adapter on the battery. To remove a restriction:

  1. Click Win + X → Device Manager.
  2. Expand the thread Network adapters, find your Wi-Fi module (for example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA61x4).
  3. RMB → Properties → Power Management.
  4. Uncheck Allow this device to turn off to save power.

3.2. Update adapter drivers

Outdated drivers may limit speed to 54 Mbit/s even on modern adapters. Let's update them correctly:

  • 🔄 Automatically: Through Device Manager → Update Driver (but Windows often doesn't install the latest version).
  • 🖥️ Manually: Download the driver from the laptop manufacturer’s website (Lenovo, HP, Dell) or chip (Intel, Qualcomm, Broadcom).
  • 🛠️ Clean installation: Before installing a new driver, remove the old one via Control Panel → Programs and Features.

For adapters Intel we recommend the utility Intel Driver & Support Assistant — it automatically finds the latest versions.

💡

If the speed drops after updating the driver, roll back to the previous version. Sometimes new drivers are optimized for power saving rather than performance.

4. DNS and routing optimization

The provider's DNS servers are often slow or block some sites. Replacing them with public ones can speed up page loading by 20–50%. Best Alternatives:

DNS server IPv4 IPv6 Pros
Cloudflare 1.1.1.1, 1.0.0.1 2606:4700:4700::1111 Fastest, DDoS protection
Google DNS 8.8.8.8, 8.8.4.4 2001:4860:4860::8888 Stable, rarely blocked
OpenDNS 208.67.222.222, 208.67.220.220 2620:119:35::35 Filtering malicious sites

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.
  3. Highlight IP version 4 (TCP/IPv4) → Properties.
  4. Set the switch to Use the following DNS server addresses and enter the selected IPs.

To check DNS speed, use the utility nslookup on the command line:

nslookup ya.ru 1.1.1.1

nslookup ya.ru 8.8.8.8

Compare response time (in ms) - the shorter the better.

5. Hardware solutions: from antennas to USB adapters

If software methods do not help, the problem may be gland. Here's what you can do without buying a new laptop:

5.1. External Wi-Fi adapters

Built-in modules in laptops are often weaker than external ones. For example, TP-Link Archer T4U (with support Wi-Fi 5) or ASUS USB-AX56 (Wi-Fi 6) can give an increase of up to 500–1000 Mbit/s even on old laptops. Key parameters when choosing:

  • 📶 Standard: Minimum Wi-Fi 5 (802.11ac), better Wi-Fi 6 (802.11ax).
  • 🔌 Interface: USB 3.0 (blue connector) - USB 2.0 will limit the speed to 300 Mbit/s.
  • 📡 Antennas: 2-3 external antennas provide better signal reception from a distance.

5.2. Strengthening the router signal

If the laptop is far from the router, try:

  • 📍 Move router to the center of the apartment and raise it to a height of 1–1.5 m.
  • 🛡️ Use repeater (For example, TP-Link RE605X) or Mesh system (Google Nest Wi-Fi).
  • 🔧 Replace antennas on the router to more powerful ones (for example, 9 dBi instead of standard 3 dBi).
⚠️ Attention: Powerful antennas (over 9 dBi) can worsen speed at close range due to the radiation pattern being too narrow. The best option for an apartment is 5–7 dBi.
How to check the real speed of the antenna?

Antenna power in dBi - this is a theoretical indicator. Real efficiency is checked as follows:

1. Connect your laptop to your router via Wi-Fi.

2. Launch a command prompt and enter:

netsh wlan show interfaces

3. Find the line Transfer rate (Mbps) — this is the current connection speed (not to be confused with Internet speed!).

4. If the value is lower 300 Mbit/s on 5 GHz, the antenna or adapter does not work effectively.

6. Hidden Windows settings that slow down the Internet

Windows 10 and 11 have hidden restrictions on network traffic that few people know about. Here's what you need to disable:

6.1. Limiting reserved bandwidth

By default, Windows reserves 20% bandwidth for system tasks (updates, OneDrive etc.). To disable this:

  1. Open Local Group Policy Editor (Win + R → gpedit.msc).
  2. Follow the path: Computer Configuration → Administrative Templates → Network → QoS Packet Scheduler.
  3. Find the parameter Limit reserved bandwidth and set the value 0%.

6.2. Disable automatic driver updates

Windows often updates network adapter drivers to Microsoft's "generic" versions, which perform worse than the original ones. To disable this:

  1. Open Settings → Update & Security → Advanced Options → Show advanced update options.
  2. Disable the option Get updates for other Microsoft products when you update Windows.
  3. B Device Manager disable automatic updates for network adapters (RMB → Properties → Driver → Roll Back, if already updated).
💡

Disabling reserved bandwidth and automatic driver updates gives a 10-30% speed increase when downloading large files.

7. Problems on the provider’s side: what to do?

If all the settings are optimized, but the speed is still low, the provider is to blame. Here's how to check and fix it:

7.1. Traffic throttling test

Some providers artificially limit the speed for certain services (torrents, Netflix, online games). You can check this like this:

  • 🔍 Download the file from TestMy.net (select 100-200 MB size).
  • 📥 Compare speed with results Speedtest. If the difference is more than 30%, the provider throttles the traffic.
  • 🛡️ Use a VPN (eg. ProtonVPN or Windscribe) — if the speed has increased, the limitation is confirmed.

7.2. Contacting support: what to say?

When contacting the provider's technical support:

  • 📊 Provide screenshots of speed tests indicating the time (preferably during peak hours - 19:00–23:00).
  • 🔌 Ask to check signal level on line (for ADSL/VDSL) or channel loading (for GPON).
  • 🔄 Demand port reconnection on the provider's switch - this solves the problem in 40% of cases.
⚠️ Attention: If the provider refuses to acknowledge the problem, file a complaint with Roskomnadzor with attached test screenshots. By law, the speed must be at least 80% of declared in the contract.

FAQ: Frequently asked questions about Internet speed on a laptop

❓ Why is the speed higher on a phone than on a laptop?

Smartphones often support more modern standards Wi-Fi (For example, Wi-Fi 6 in iPhone 12+ or Samsung Galaxy S21+), while economy class laptops (Lenovo IdeaPad, HP Pavilion) can use Wi-Fi 4 or Wi-Fi 5 with cut down antennas. Also, phones often update drivers automatically.

❓ How to check if my laptop supports Wi-Fi 6?

Open Device Manager → Network Adapters and find the Wi-Fi module model. Type its name into Google along with the words “specs” or “documentation.” Look for standard support 802.11ax (that's what it is Wi-Fi 6). For example, adapters Intel AX200/AX201 or Qualcomm FastConnect 6800 support Wi-Fi 6.

❓ Can an antivirus slow down the Internet?

Yes, especially if it has a network traffic inspection module (for example, in Kaspersky Internet Security or ESET NOD32). Disable options like “Scanning HTTPS traffic” or “Network protection” in your antivirus settings. Also check if it is blocking DNS requests - this can slow down the loading of sites.

❓ Is it worth buying a laptop with Wi-Fi 6E?

Wi-Fi 6E supports frequency 6 GHz, which gives additional 1200 MHz free spectrum and speed up to 2–3 Gbit/s. However, to use it you need:

  • Router with support 6 GHz (For example, ASUS RT-AX89X or Netgear Nighthawk RAXE500).
  • No interference - frequency 6 GHz does not pass through walls well.
  • Tariff from the provider with higher speed 500 Mbit/s (otherwise the increase will not be noticeable).

For most users Wi-Fi 6 (without 6E) is more than enough.

❓ How to speed up the Internet in online games?

To reduce ping (ms) and eliminating lags:

  1. Connect to the router via cable (Ethernet).
  2. In the router settings, enable QoS (Quality of Service) and set priority for game traffic (select game port or laptop IP).
  3. Use DNS from Cloudflare (1.1.1.1) or Google (8.8.8.8) - they are optimized for game servers.
  4. Close background programs that consume traffic (Discord, Steam, browser with open tabs).
