There are numerous elements that can influence the speed of your internet connection, and tackling as many of them as possible is key to achieving a faster and more stable connection. 

Once you’ve applied the tips outlined below, you’re likely to experience an improvement in speed. 

After implementing these steps, it’s also wise to use a dedicated device cleanup tool to enhance your device’s performance and resolve any issues that could be contributing to your internet slowdown.

What causes slow internet?

Sluggish internet performance can result from a variety of causes — for instance, being too far away from your Wi-Fi router, having outdated device drivers, running too many programs in the background, or even having malware installed on your system. 

It may be a single issue or a mix of several. That’s why it’s important to go through all possible solutions to identify what might be affecting your connection.

Ways to improve your internet speed

Boosting your internet speed can be accomplished in multiple ways, including updating your internet browser, running antivirus scans, restarting your gadgets, investing in a Wi-Fi range extender, or changing the Wi-Fi channel on your router.

If you suspect that your slow speeds stem more from your device than your internet connection, it may be helpful to look into specific resources tailored to speeding up your PC, enhancing your Mac’s performance, or improving how your Android or iPhone functions.

Here are 21 effective strategies to help you speed up your internet connection across phones, computers, and home networks:

1. Reduce the distance between your router and the device

One of the simplest ways to enhance your internet speed is by moving your device closer to your router or relocating the router itself.

The further your device is from the router, the weaker the connection becomes.

You don’t need to sit right next to your router, but a shorter distance often results in a stronger signal.

Ensure there are no thick or concrete walls between the router and your device, as these can greatly hinder signal strength.

Keep in mind that not all routers perform equally. Some provide robust signals, while others might be underpowered.

If your connection is weak even when you’re near the router, consider upgrading to a more powerful model.

2. Tidy up your cables

Connecting your computer directly to the router via an Ethernet cable generally delivers the fastest possible connection.

For maximum efficiency, use a cable that is short, undamaged, and of high quality.

After facing constant buffering issues and slow downloads with a 50-inch Ethernet cable, switching to a shorter, 30-inch cable from a reputable brand solved the problem instantly.

Using a good-quality cable can help you make full use of the speed offered by your internet service provider.

3. Clear cached data and browsing history

A buildup of cached data can slow down or disrupt how websites load. Removing this data can significantly improve browser performance.

Note that clearing your cache might log you out of sites you regularly visit, so be sure to have your login information on hand.

To clear your cache in Google Chrome:

• Open Chrome, click on the three dots in the top-right corner, go to More tools, then click Clear browsing data.

• Ensure that options like Browsing history, Cookies and other site data, and Cached images and files are selected.

• Click Clear data.

This can also be done on mobile browsers by navigating to the settings within the browser app.

4. Keep your browser up to date

An outdated browser can lead to performance and security issues.

Regularly updating your browser ensures smoother operation and often includes fixes for bugs and other problems.

To update Google Chrome:

• Click the three-dot menu, scroll to Settings, and go to About Chrome.

To update Mozilla Firefox:

• Click the three-line menu, go to Help, and click About Firefox.

5. Scan for malware and viruses

Viruses and other malicious software can greatly affect internet performance by consuming bandwidth and system resources.

These threats can make their way into your system through unsecured public Wi-Fi or phishing schemes.

Using security tools like Avast One can help detect and remove malware from your system.

This software not only improves security but also includes tools to enhance your computer’s performance, ensuring it runs at optimal speed.

6. Shut down bandwidth-intensive programs and applications

If your internet is sluggish on your computer but fine on other devices, there might be background programs using a lot of your bandwidth.

To identify and stop them:

• Right-click your Windows taskbar and choose Task Manager.

• Click on the Network column under the Processes tab to sort by bandwidth usage.

• If you see programs like OneDrive consuming large amounts of data, right-click and choose End task to stop them.

This provides a temporary boost. To prevent them from restarting automatically, consider using performance optimization tools such as Avast Cleanup, which can put such applications into Sleep Mode, pausing their activity until needed again.

7. Decongest your home network

When several devices are connected to your network, it can cause interference and decrease performance.

Here’s how to manage network traffic more effectively:

• Disconnect devices that aren’t in use. Some devices, like smart TVs or consoles, may download updates quietly in the background.

• Enable Quality of Service (QoS) on your router. This lets you give priority to specific activities (like streaming or gaming) over others.
  
  • Access your router settings via its IP address (typically printed on the device).
  • Log in using your admin credentials.
  • Find the section labeled QoS, Advanced Settings, or Traffic Management, and enable it.
• Stagger bandwidth-heavy activities so they don’t all happen at once. Coordinate with others in your household to avoid internet slowdowns.

• Create a guest network using the 2.4GHz band for visitors. This can help manage overall bandwidth more effectively and adds a layer of privacy and security to your home network.

8. Restart your device

Rebooting your device can resolve temporary glitches and refresh your network settings, which often leads to faster internet.

Steps for various devices:

• Windows PC: Click the Start icon, then the power icon, and select Restart.

• Mac: Click the Apple icon and choose Restart.

• iPhone: Press and hold the side button until the power slider appears, turn the device off, wait about ten seconds, then turn it back on.

• Android: Press and hold the power button, then select Restart.

9. Restart your modem or router

Sometimes, the router or modem itself is the bottleneck. Restarting it can flush out any issues caused by cached data or minor bugs.

To do this properly:

• Unplug your modem or router from the power source.

• Wait for at least 30 seconds before plugging it back in.

This often helps refresh your internet signal and can restore normal speeds.

10. Keep your operating system up to date

System updates are frequently released to fix bugs and improve overall performance. These updates can include enhancements that indirectly boost your internet speed.

Ensure your device has enough storage before updating — generally, having at least 10% of your total disk space available is a good guideline. 

Whether you’re on a PC, Mac, iPhone, or Android, freeing up space helps ensure updates install correctly and your device performs efficiently.

11. Update your network drivers

For Mac users, driver updates are generally handled automatically through macOS updates.

Windows users, however, may need to manually update drivers if the system fails to install the most recent versions.

To update your network drivers manually on Windows:

• Type Device Manager into the search bar and open it.

• Expand the Network adapters section.

• Right-click the adapter you want to update and select Update Driver.

If Windows doesn’t find an update, you can visit the manufacturer’s website to download the latest version and follow the installation instructions.

For automatic updates, a tool like Avast Driver Updater can streamline the process and ensure all your drivers — including those for networking — are current and functioning correctly.

12. Update Router Firmware 

It’s possible that your router’s firmware needs to be updated. To check, access your router’s web interface through a browser.

Refer to the router’s manual or look for the IP address on the back of the router for this. 

Once you’ve logged in to the router’s interface, look for a button or link labeled something like “Check for Updates.”

Updating your router’s firmware could enhance your internet speed. Follow the instructions to install any available updates.

If the slow connection was caused by outdated firmware, updating it may resolve the issue and improve your internet speed.

13. Switch to a Wired (Ethernet) Connection 

If Wi-Fi speeds continue to disappoint, consider switching to a wired connection. Plug an Ethernet cable into your PC or Mac and connect it directly to your router. 

A wired connection offers the fastest possible speeds, potentially reaching several gigabits per second, ensuring a more reliable and stable connection.

Ethernet connections are generally faster and more stable than wireless ones, which can significantly improve your internet experience.

14. Map Your Home’s Wi-Fi Signal Strength to Improve Your Connection

Instead of wasting time moving your router or computer around trying to find the best position, consider mapping the signal strength in your home.

Tools like Heatmapper can assist in determining which areas of your home have strong Wi-Fi coverage. 

After installing Heatmapper, you’ll need a floor plan of your home—either one you already have or one you create as you go around.

The tool will give you a map showing where the Wi-Fi signal is strongest and weakest, helping you to position your router more effectively.

Knowing where the signal is weakest will help you make adjustments to your router placement, allowing for better internet speeds in the areas where you need them the most.

15. Install a Wi-Fi Extender 

If your router’s signal can’t cover your entire home effectively, using a Wi-Fi extender or repeater might be the solution.

A Wi-Fi extender connects to your router’s signal and amplifies it to reach areas where the signal is weak. 

This can eliminate Wi-Fi dead zones and improve the internet experience across your home, especially if relocating the router is not an option.

Wi-Fi extenders are a simple and effective way to ensure that your internet connection remains stable and fast throughout your space.

16. Use an Ad Blocker 

Many websites are loaded with advertisements, especially those that play videos automatically.

This doesn’t only affect your sanity—it also impacts your internet speed, as these ads use bandwidth that could otherwise be dedicated to your tasks. 

Installing an ad blocker or using a privacy-focused browser can significantly reduce the amount of unwanted data, allowing more of your internet connection to be used for browsing.

By blocking intrusive ads, you free up bandwidth, allowing for a smoother browsing experience.

17. Consider Switching Internet Providers 

If you’re not satisfied with your current internet speed, your ISP might be the issue.

Some providers intentionally limit your connection speeds (a practice known as throttling), especially if they suspect heavy data use. 

Even if your plan includes unlimited data, ISPs can still throttle speeds under certain circumstances, such as peak usage times or high data consumption.

Before switching providers, explore options to stop throttling and check if upgrading your current plan could help.

If your current provider still doesn’t meet your needs, it may be time to consider switching. 

Be sure to understand the terms of terminating your contract with your current ISP and compare plans from other providers to find one that offers better speeds.

18. Use a High-Speed VPN

If you suspect your internet is being throttled but don’t want to change ISPs, a VPN might help.

While a VPN routes your internet traffic through secure servers, which can sometimes reduce speeds slightly, it can also prevent ISPs from throttling your connection. 

This happens because a VPN masks your IP address, making it difficult for your ISP to track how much bandwidth you’re using, which may allow for faster speeds.

With a good VPN, such as Avast SecureLine VPN, you can enjoy faster browsing while also securing your online privacy.

VPNs are easy to install on computers, phones, or tablets, and can be managed directly from the app.

19. Secure Your Wi-Fi with a Password 

If your Wi-Fi network is unsecured, outsiders may be able to connect and use your internet, which can slow it down.

Most routers come with a default password, but these aren’t always secure. To change the password:

• Enter your router’s IP address in your browser.

• Log in using the router’s admin username and password.

• Look for the Wi-Fi password settings and change it to something strong.

• Choose WPA2 or WPA3 security to encrypt your connection, as these are the strongest available.

A secured Wi-Fi network prevents unauthorized use, ensuring your connection remains fast and reliable.

20. Change Your DNS Server 

The DNS server functions like an address book for the internet, converting website names into IP addresses. 

If your DNS server is slow, it could impact your internet speed. Google’s public DNS servers are considered fast and reliable, and using them might improve your browsing speeds.

How to change DNS on Windows:

1. Open Settings > Network & Internet > Advanced network settings.
2. Under Related settings, click on “More network adapter options.”
3. Right-click your connection and select Properties.
4. Select “Internet Protocol Version 4,” then click Properties.
5. Choose “Use the following DNS server addresses” and enter the following:
   • Preferred DNS server: 8.8.8.8
   • Alternate DNS server: 8.8.4.4

How to change DNS on a Mac:

1. Open System Settings > Network.
2. Select your active connection, then click Details.
3. Click DNS and add the Google DNS addresses:
   • 8.8.8.8
   • 8.8.4.4

21. Switch Your Wi-Fi Channel 

Wi-Fi channels differ in how much data they can handle, and some channels may be overcrowded. Changing to a less crowded Wi-Fi channel could improve your internet speed.

To change your Wi-Fi channel, access your router’s settings and find the channel option. You’ll see a list of channels to choose from. 

If the channels are too close to each other, they might overlap, so select a channel that is further away from the current one for optimal performance.

Ways to Boost Download Speed 

Download speed, which determines how quickly data transfers from the internet to your device, is an important aspect of internet performance. 

Most people will be satisfied with speeds of around 20 Mbps, but if you engage in high-demand activities like gaming, 100 Mbps or more may be necessary.

To improve download speeds, try the following:

• Close unused apps and programs.

• Clear your browser’s cache and cookies.

• Disconnect devices that are using your network.

• Download one file at a time.

• Restart your device or router.

• Run antivirus scans to eliminate any malware.

Why Your Download Speed Might Be Slow Despite Fast Internet?

Your download speed may be sluggish for several reasons, even if your internet plan offers high speeds.

Common causes include throttling by your ISP, outdated routers, or faulty cables.

Even if you’re paying for a plan with 100 Mbps, you may not receive those speeds due to limitations in your equipment or connection.

Improving Upload Speed 

Upload speed refers to how quickly data can be sent from your device to the internet.

It’s important for activities like streaming, gaming, or video calls. To enhance upload speeds:

• Consider upgrading to a faster ISP plan.

• Update your router firmware.

• Close any background programs.

• Restart your router.

• Upgrade to a more advanced router.

How To Test Your Internet Speed?

To determine your current connection speeds, use an internet speed test like the one at speedtest.net.

The test will show you your download and upload speeds in megabits per second (Mbps). You can also use Google’s “internet speed test” feature for a quick check.

A good internet connection typically has a download speed of at least 100 Mbps and an upload speed of 20 Mbps.

If these speeds are lower than expected, take steps to improve them as described above.
