How to Fix Slow Internet Connection?
Let’s find out how to increase download speed and get rid of slow internet connection.
Phase 1: Quick Checks (Most Common Fixes)
1. Test Your Connection on Another Device
If only one device experiences slow internet, the problem may be with that device rather than your network. Compare speeds on a smartphone, laptop, or another computer before troubleshooting your entire internet connection.
2. Check Your Speeds and Your Plan
You’ve subscribed to a higher Internet package, but you’re still getting slow speeds. Either log on to your ISP’s website or call them to find out what plan you have. Then, go to Speedtest.net or DSLreports.com and run a speed test. Repeat several times a day to see if the speed varies. If you’re getting the speeds you’re paying for, then it is fine. Otherwise, you need an upgrade.
3. Restart Your Fiber ONT
If you use fiber internet, restart both the ONT and the router. Unplug them for 30 seconds, reconnect the ONT first, wait for it to fully reconnect, then power on the router.
The ONT (Optical Network Terminal) may also need rebooting.
4. Check Service Outages
Before troubleshooting:
- Check ISP status page
- Search outage reports
- Check local community groups
Many speed issues are ISP-side.
5. Compare Ethernet and Wi-Fi Speeds
If Ethernet is fast but Wi-Fi is slow:
- Router placement
- Interference
- Old Wi-Fi standard
are likely causing the issue.
Phase 2: Home Network Problems
6. Fix Your Wi-Fi Signal
Wi-Fi and other types of wireless connections may become slow due to signal interference. Your router and internet may be fine, but your wireless signal is weak, causing a slow internet connection.
Household appliances and even nearby Wi-Fi networks may cause interference. Password-protect, reposition, and tweak your router for better performance and change your Wi-Fi channel number. Another tip – The closer you are to the router, the better your connection.
7. Disconnect Unused Devices
Too many devices might be consuming bandwidth unnecessarily:
- Smart TVs
- Security cameras
- Gaming consoles
- Cloud backups
- Smart home devices
- can consume bandwidth.
8. Check Cloud Services
Pause the following services while testing your internet speed:
- Google Drive
- OneDrive
- Dropbox
- iCloud
9. Turn Off Bandwidth-Hogging Apps
Your hardware may work fine, but other programs could take over the connection. Check for uploads and other processes running behind other apps minimized to the system tray consuming network resources.
Videos requiring games and programs take up a lot of data, causing your connection to be sluggish. Ensure no programs run in the background when troubleshooting a slow internet connection.
You can use content-blocking extensions carefully if websites are overloaded with ads or resource-heavy scripts. Content-blocking extensions can reduce the impact of ads, autoplay videos, and heavy scripts that consume bandwidth.
Also check for operating system updates, game launchers (Steam, Epic Games, Xbox), and large file downloads running in the background. These can consume significant bandwidth without you realizing it.
10. Reduce Network Congestion During Peak Hours
Network congestion during peak hours can slow internet speeds when many users in your area are online simultaneously.
Schedule large downloads, cloud backups, and software updates during off-peak hours when fewer devices are using the network. If a task is urgent, consider using a trusted mobile hotspot or public Wi-Fi connection.
11. Optimize Router Placement
Avoid placing your router inside cabinets, behind TVs, near microwaves, cordless phones, or large metal objects. For best coverage, place it in a central, elevated location.
12. Upgrade to Wi-Fi 6 or Wi-Fi 7
Older routers using:
- Wi-Fi 4 (802.11n)
- Early Wi-Fi 5
can create bottlenecks.
Wi-Fi 6 and Wi-Fi 7 significantly improve:
- Speed
- Latency
- Device handling
Phase 3: Hardware & Configuration
13. Check Whether a VPN Is Slowing Your Connection
Temporarily disconnect your VPN and run another speed test. If speeds improve significantly, the VPN server may be causing the slowdown.
Many people now use:
- NordVPN
- ExpressVPN
- Surfshark
- Proton VPN
- Corporate VPNs
This is often overlooked.
14. Check for Malware and Unwanted Software
Malware, spyware, cryptominers, and unwanted software can consume bandwidth and system resources. Run a full system scan using a trusted antivirus solution and remove any suspicious programs that may be affecting performance.
15. Update Network Drivers
Outdated Wi-Fi and Ethernet drivers can cause connectivity issues and poor performance. Check your device manufacturer’s website or use Windows Update to install the latest network drivers.
Phase 4: Hardware & Configuration
16. Troubleshoot Your Hardware
Don’t go cursing your ISP. Check your modem and router first. If they need a reset, do so and see if that helps.
- An outdated network or faulty equipment may affect your connection.
- Rearrange and reconfigure, if need be. Bypass your router, swap cables, and test with multiple devices before upgrading, repairing, or replacing.
Work through these troubleshooting steps one by one to determine whether the issue is caused by your hardware.
If it’s not, fix or upgrade your router or modem, and you should be browsing speedily once again.
17. Try Another DNS Server
Sometimes, the DNS server you’re on can be down. Changing DNS may improve website lookup times if your ISP’s DNS servers are slow or unreliable, but it will not usually increase your raw download speed. If your default DNS server is fine, there’s no need to go on an alternative server.
Popular DNS:
- Google DNS (8.8.8.8)
- Cloudflare DNS (1.1.1.1)
Phase 5: Temporary Workarounds
18. Use Data-Saving Techniques
- Consider mobile hotspot as backup
- Use lightweight/mobile websites
- Disable unnecessary media
- Use Reader Mode when available
Phase 6: ISP Escalation
19. Call Your ISP
Speed depends on your ISP. Your ISP may be having issues. Call them and see if the problem is at their end. Your service provider could have changed their network configuration or installed filters and controls, causing a slow internet connection. Also, if you’ve been paying for slow speeds all this time, chances are you can get a better deal on your internet with your ISP.
20. Get a New Service Provider
Your ISP doesn’t provide the speeds you want? Sick of their horrible customer service? It’s time to find a new one. It can be difficult as ISPs can stifle competition and give consumers a few options. But first, understand what kind of connection you want – cable, satellite, or fiber.
You should do a little research before you pick up the phone. Choose the best provider in your area and ensure they provide the speeds you want. Stream videos and movies, listen to your favorite songs, and download photos without interruptions and data caps.
Phase 7: Device Performance
21. Delete Browsing Data and History
Clearing browser cache may fix website loading problems or outdated content, but it typically does not increase your actual internet connection speed.
22. Improve Device Performance
While SSD health does not directly affect internet speed, low storage can make downloads, browsers, and applications feel slower.
If your device uses an SSD, ensure:
- SSD firmware is updated
- At least 15–20% free storage
- TRIM is enabled
Bonus tip: When to Upgrade Your Router
Consider replacing your router if:
- It is more than 5 years old.
- It only supports Wi-Fi 4.
- It frequently disconnects.
- You recently upgraded to fiber internet.
- You have many smart home devices.
