Understanding Your Baseline: Running a Speed Test

The first step in troubleshooting slow internet is to establish a baseline. You need to know what speeds you’re actually getting compared to what you’re paying for. This is where a speed test comes in handy.

There are numerous free online speed tests available, such as Speedtest by Ookla, Fast.com (powered by Netflix), and Google’s Speed Test. These tests measure your download speed, upload speed, and ping (latency).

To get the most accurate results, follow these tips:

Close all other applications and browser tabs that might be using the internet.
Connect directly to your router with an Ethernet cable. This eliminates potential Wi-Fi interference.
Run the test multiple times at different times of the day. Internet speeds can fluctuate based on network congestion.

Once you have your results, compare them to the speeds listed in your internet plan. If your speeds are consistently significantly lower than what you’re paying for, there may be a problem with your ISP.

Is it Your Wi-Fi? Investigating Your Wireless Network

Wi-Fi is a common source of internet speed issues. Many things can interfere with a Wi-Fi signal, leading to slow speeds and dropped connections.

Wi-Fi Interference

Wi-Fi signals operate on specific channels, and if too many devices are using the same channel, it can cause interference. Microwaves, cordless phones, and even Bluetooth devices can also interfere with Wi-Fi signals.

You can use a Wi-Fi analyzer app (available for smartphones and computers) to see which channels are the most congested in your area. Then, access your router’s settings and switch to a less crowded channel. This can often improve your Wi-Fi performance significantly. Experiment with different channels to find the one that provides the best speeds.

Router Placement

The location of your router can also impact your Wi-Fi signal. Walls, furniture, and other obstacles can weaken the signal.

Try placing your router in a central, open location, away from walls and obstructions. Elevating the router can also improve its range. Avoid placing it near metal objects or appliances that emit electromagnetic radiation.

Router Age and Capabilities

Older routers may not be able to handle the demands of modern internet usage. If your router is several years old, it might be time for an upgrade. Newer routers support faster Wi-Fi standards (like Wi-Fi 6 or Wi-Fi 6E) and can handle more devices simultaneously.

Consider upgrading to a mesh Wi-Fi system, especially if you have a large home. Mesh systems use multiple nodes to create a seamless Wi-Fi network, eliminating dead spots and providing consistent coverage throughout your home.

Securing Your Wi-Fi Network

Make sure your Wi-Fi network is password-protected and using a strong password. Unsecured Wi-Fi networks can be easily accessed by neighbors, who may be using your bandwidth without your knowledge. This can significantly slow down your internet speeds. Enable WPA3 encryption for the best security.

Checking Your Devices: Are They the Problem?

Sometimes, the problem isn’t your internet connection, but the device you’re using to access it.

Too Many Devices

Each device connected to your Wi-Fi network consumes bandwidth. If you have too many devices streaming video, downloading files, or playing online games simultaneously, it can strain your internet connection and slow down speeds for everyone.

Try disconnecting some devices from your Wi-Fi network to see if that improves the speed on the device you’re using. Prioritize bandwidth for the devices that need it most. Many routers offer Quality of Service (QoS) settings that allow you to prioritize bandwidth for specific devices or applications.

Malware and Viruses

Malware and viruses can consume bandwidth and slow down your internet connection. Run a full system scan with a reputable antivirus program to check for any infections. Keep your antivirus software up to date for the best protection.

Background Processes

Many applications run in the background, even when you’re not actively using them. These applications can consume bandwidth and slow down your internet speed.

Close any unnecessary applications and disable any background processes that you don’t need. Use the Task Manager (Windows) or Activity Monitor (macOS) to see which processes are using the most bandwidth.

Outdated Software and Drivers

Outdated software and drivers can sometimes cause compatibility issues that lead to slow internet speeds. Make sure your operating system, web browser, and network drivers are all up to date. Regularly check for updates to ensure optimal performance.

Your Internet Plan: Is It Enough?

The speed of your internet plan can also be a limiting factor. If you’re regularly experiencing slow internet speeds, even after troubleshooting the other potential causes, it might be time to upgrade to a faster plan.

Assessing Your Needs

Consider how you use the internet and how many people are using it in your household. If you’re streaming video in 4K, playing online games, or working from home, you’ll need a faster internet plan than someone who only uses the internet for basic browsing and email.

Talk to your ISP about upgrading to a plan that better meets your needs. They can help you determine the appropriate speed for your usage.

Understanding Bandwidth Caps

Some ISPs have bandwidth caps, which limit the amount of data you can use each month. If you exceed your bandwidth cap, your speeds may be throttled, resulting in slower internet performance.

Check your internet plan to see if there is a bandwidth cap. If so, monitor your data usage to avoid exceeding the limit. Many ISPs offer tools to track your data usage online.

Taking Action: Steps to Improve Your Internet Speed

Once you’ve identified the cause of your slow internet, you can take steps to improve your speeds.
