Common causes of slow internet

Have you ever wondered why your internet is slow? Understanding the factors that lead to slow internet connections can help resolve speed issues. Here are some of the common reasons why your internet might be slow.

Network congestion

Network congestion occurs when many users try to access the internet simultaneously, straining the shared bandwidth. Network congestion is more likely during peak hours, such as in the evenings or high-traffic events.

During these periods, some Internet Service Providers (ISPs) may employ network traffic control measures such as throttling, which can decrease the speed of your connection.

Additionally, emerging technologies like 5G home internet experience slow speeds due to network congestion. The slow speeds are apparent in densely populated areas where cellular and home internet users compete for 5G signals, reducing internet performance.

Outdated hardware

Outdated modems, routers or network adapters can cause drastically reduced internet speeds. Old devices often cannot support recent internet upgrades like WiFi 6, which has significantly improved internet speeds and bandwidth capacity.

That’s why it’s important to regularly update the firmware on your devices and consider replacing them if they are too old to support the latest WiFi standards.

Interference from other devices

Many electrical devices can also disrupt wireless signals. Common household appliances like microwaves, Bluetooth devices and speakers operating on the same 2.4 GHz frequency band as the routers can interfere with wireless signals, weakening the connection and leading to slower internet speeds.

Distance from the router

The further you move away from the router, the weaker the WiFi signal becomes. Thick walls and multiple floors obstruct the WiFi signals, leading to signal degradation. Signal degradation results in slower speeds and frequent dropped connections.

To maintain the strength of the signals as you move away from the router, consider using a mesh WiFi system to extend the WiFi coverage and maintain signal strength throughout your home.

Too many connected devices

As you increase the number of devices connected to your router, the available bandwidth for each device decreases. Having too many devices running at the same time can slow your speeds significantly, especially if the devices are simultaneously performing data-intensive tasks such as online gaming and streaming 4K quality content.

Background applications and updates

Idle applications and operating systems that perform updates or background operations consume a lot of bandwidth without your knowledge. For instance, downloading large files, installing online updates and synchronizing with a cloud service in the background can slow down your internet speed, particularly if these processes are running simultaneously.

Diagnosing your slow internet

Now that you know what can cause a slow internet connection, it’s time to diagnose where the problem is in your network.

Running speed tests

Start with a speed check test to measure your current internet speed. Speed tests will help you determine whether your current download and upload speeds match what your ISP provides. Run the speed tests at different times of the day on various devices to gain insight into the consistency of your connection.

Be sure to run your tests with your VPN on and then again when it’s off. The VPN encrypts your internet traffic, making it difficult for ISPs to identify and potentially throttle the connection. If the speeds are better when the VPN is active, your ISP might be throttling your connection.

If your speeds frequently fall below what your plan promises, you should contact your ISP. Keep track of your speed test findings and share them if necessary.

Checking for device issues

Sometimes, a slow internet speed experience stems from a device rather than a network issue. Test your internet connection on multiple devices to determine if the problem comes from a specific device. Also, update your devices’ software and install antivirus software to search for and eliminate any malware that might consume bandwidth or slow down the device.

If you notice an increase in speed on one device compared to another, the problem is probably with the latter. Focus on troubleshooting the faulty device.

Analyzing network traffic

You can use your router’s admin interface to monitor connected devices and their bandwidth usage. Some routers have features such as traffic monitoring and Quality of Service (QoS) functions that can help you monitor and dedicate traffic and bandwidth to specific devices or applications.

Pay attention to background processes and programs on your devices that might consume bandwidth without you noticing. Such insights can help you adjust network and bandwidth usage settings accordingly.

Solutions to improve internet speed

Once you’ve diagnosed the reason for your slow internet speed, you can follow the below solutions to improve it.

Upgrading your hardware

Replace older devices with newer ones, such as routers and modems compatible with WiFi 6 or higher. Modern routers and modems support faster internet speeds, lower latency, higher bandwidth and device capacity and broader network coverage.

Upgrade your primary devices to enhance your internet experience. Newer device models provide better hardware capabilities and support the latest WiFi technologies and faster internet speeds.

Optimizing router settings

Modern routers provide several features you can tweak to increase WiFi speeds. Some measures include changing the WiFi channels to avoid interference from surrounding networks or modifying QoS settings to allocate bandwidth for essential applications like video calls or gaming.

If you are a competitive gamer and experience slow internet speeds with your current router, consider using a gaming router to optimize your internet connection and enhance your gaming experience.

Reducing interference

Move the router to the center of the house, away from electronic devices that might interfere with the WiFi signals. Place the router in a raised position, such as on top of furniture or shelves, to provide unobstructed coverage.

In addition, use a wired Ethernet connection for devices that require high speed and consistent performance. Wired connections are less prone to electromagnetic interference and offer more stable, reliable and faster internet speeds than wireless connections.

Managing connected devices

By minimizing the number of connected devices within a network and ensuring that idle devices are disconnected, you reduce the strain on your connection. You can use parental controls to manage devices or set up guest networks to separate traffic from your primary network.

Astound’s Whole Home WiFi with eero subscription comes with eero Secure, which has parental controls, the ability to set up guest networks and more, at no additional cost.

Contacting your internet service provider (ISP)

If the above troubleshooting attempts fail, contact your ISP for assistance with possible network problems or to help find the best internet speed for your needs. Remember to document your troubleshooting measures and speed test results before contacting your ISP, as this information will help them resolve your issues quickly.
