Your internet connection may be interfered with if it keeps cutting out. Problems like a router glitch, damaged cables, or too many devices on your network can slow down your speed.

These issues are often easy to fix with basic troubleshooting.

Common Reasons Your Internet Disconnects

Below are the leading causes of internet disconnections and how to solve them. Click on a problem to jump to its solution.

Restart Your Modem and Router

Modems and routers work like small computers with specific tasks. Sometimes, their memory gets cluttered, causing errors. Restarting both devices helps clear those errors.

Weak or Unstable Wi-Fi Signal

Obstructions, limited range, or interference from other networks and devices can weaken Wi-Fi signals.

Too Many Devices on Your Network

When too many devices use the internet simultaneously, your network slows down. Reducing usage, upgrading your router, or switching to a better plan can help.

Internet Outages

Outages happen due to issues with your provider’s infrastructure. You cannot prevent them, but changing providers may be necessary if they occur often.

Faulty Network Cables

Broken cables are difficult to find because the damage is not always visible. A technician might need to check and fix them.

Reason #1 – Restart Your Modem or Router

If your internet has problems, restart the modem or router first. It connects to your provider’s network and may be causing the issue.

Next, restart your router. It controls your home network and links to your provider’s modem.

Restarting both devices helps fix connection issues. Follow these steps:

• Step 1: Unplug the power cable from the device.

• Step 2: Wait 60 seconds.

• Step 3: Plug the power cable back in.

• Step 4: Wait for the device to restart.

Reason #2 – Weak Wi-Fi Signal

Wi-Fi signals weaken over distance. If you are far from the router, your internet may drop as the signal struggles to reach your device.

Objects between the router and your device can also cause disconnections.

Check your device’s Wi-Fi signal strength. Notice where the signal drops while moving around. Look at what is blocking the signal in those areas.

Certain materials like metal, stone, tile, and water weaken Wi-Fi. Avoid placing your router where the signal must pass through these materials.

For example, do not put the router behind metal furniture, near a tiled bathroom, or close to a fish tank.

Some electronics, like microwaves, baby monitors, and garage door openers, can also interfere with Wi-Fi and cause connection issues.

Improving Wi-Fi can be tricky, but simple changes help. Place your router in the best spot and adjust settings to extend the Wi-Fi range.

Reason #3 – Too Many Devices on Your Network

Network congestion happens for two reasons or both at the same time:

• Your router cannot support all your devices.

• Your internet plan does not have enough bandwidth.

Cheaper routers often have limited capacity. A basic router that connects only two devices will be much slower than one that supports 12.

Similarly, a router with a Gigabit Ethernet port will slow down a 2Gbps internet plan.

A slow internet plan can also cause problems. No matter what router you use, a weak plan may not support all the devices in your home.

A 500Mbps plan usually works for five adults in one household.

Look at your provider’s advertised speed to check if you need a better plan.

Set aside 100Mbps per person, total the amount, and compare it to your current plan. If your speed is too low, upgrading to a faster plan may help.

Reason #4 – Internet Outages

If your internet disconnects randomly, your provider might have network issues. Outages can last for hours or happen on and off.

To check outages, use your provider’s app, log in to your account, or call customer service.

Call and ask about previous outages to check if they caused your frequent disconnections. Most providers track service interruptions.

A support agent can share how many outages happened at your address and their dates. They might also provide an estimated time for the fix.

Reason #5 – Problems with Network Cables

Faulty network cables in your home can cause internet disconnections. Damage, loose connections, or poor setup may be the issue.

What to Check:

• Damaged Cables
  Check all network cables for any damage. Look for bends, chew marks, or cuts. Make sure coaxial wires are secure on both the modem and the wall. Also, inspect the Ethernet cable that connects the modem to the router or computer.
  
• Loose Cables
  Tightly screw in coaxial cables. Ethernet cables click when connected and stay secure unless pressing the clip. Loose cables send a weak signal but fail with movement. A damaged or loose Ethernet clip causes connection problems.
  
• Unused but Active Coaxial Lines
  An active but unused coaxial line can cause interference. If a technician installs your internet, request they close any open coaxial outlets. Finding these open lines is hard without special tools.

Ethernet cables are usually simple to fix. However, coaxial and fiber cables need special tools. Contact your internet provider for repairs.

Your internet keeps disconnecting for other reasons

If you’re still unsure, don’t worry. There are more solutions to try.

Modem problems

Your modem must communicate properly with your internet provider. If it doesn’t, you may face connection issues.

A registration problem in the modem makes it keep verifying with the provider, which blocks internet access.

Using a personal modem or getting a new one from the provider causes the issue more often.

If the modem isn’t working right, contact your internet provider. It can check whether the modem is updated, compatible, and properly registered.

Some customer service agents may not have access to specific tests, so you might need to ask for a technician visit or escalate the issue.

You need clear answers to these questions:

• Is my modem registered?

• Is my modem still compatible?

• Is my modem connecting to the network?

Restart your device

Restarting can remove system glitches, including network problems.

Update your device

Devices need software updates for security fixes, bug removal, and better performance.

Updates usually happen automatically, but check to ensure your device is up to date before troubleshooting further.

Wi-Fi network switching

Your device may switch between known Wi-Fi networks, causing brief disconnections. If the Wi-Fi signal is weak, it may automatically search for a stronger one.

Disable auto-join or auto-switching settings on your device and manually connect to your preferred Wi-Fi network.

Your device uses a busy Wi-Fi channel

Your router broadcasts Wi-Fi signals on specific radio frequency channels. It combines several channels to increase speed.

When many networks use the same channels, they overload. Overloading happens in apartments or areas with multiple routers nearby.

Routers and mesh systems usually choose the best channels automatically. A Wi-Fi analyzer app shows available channels and their usage.

You can manually switch channels on your router or mesh system if available. Changing the channel may or may not improve the connection, depending on your location.

Pro Tip:

To switch your Wi-Fi channel, log in to your router and go to the settings. The option is usually under the “Wi-Fi” or “wireless” tab.

Your network adapter requires a driver update

Your operating system updates network adapter drivers automatically unless you turn off auto-updates. Still, checking for updates can help fix issues.

Follow these steps to update network adapter drivers in Windows:

1. Right-click the Start button and choose Device Manager.
2. Expand Network Adapters.
3. Right-click your network adapter (Wi-Fi or Ethernet) and click Update Driver.
4. In the dialog box, select Search automatically for drivers.
5. Follow the on-screen steps to finish updating.
6. Restart your computer.

If you get a message that says, “The best drivers for your device exist,” it might be wrong.

Go to the network adapter maker’s website and get the newest drivers. You don’t always need Device Manager to install them.

Your computer needs a network reset

Resetting network settings can fix connection problems. It removes all network details from your computer.

You must reinstall networking software like VPNs and antivirus programs. Your home network will also need reconnection. Keep your login details ready before starting.

Steps to reset network settings on Windows:

1. Click the Start button.
2. Open Settings.
3. Go to Network & Internet.
4. Select Advanced network settings.
5. Click Network reset.
6. Follow the on-screen steps.
7. Restart your computer.

Your antivirus software needs updates

Your antivirus protects your device. It blocks harmful internet traffic but must recognize safe and unsafe data.

That requires frequent updates. Most antivirus programs have an auto-update option. Keep it on.

Turn off your antivirus for a short time

Staying online without protection is risky, but you should turn off your antivirus briefly to check if it causes the issue. It may block a program and cut off your internet.

If turning off the antivirus restores your connection, turn it back on and contact tech support. You should stop the conflicting program or switch to another antivirus quickly.

Programs that update often or connect to servers in the background can disrupt your internet. Watch for cloud services and software with licensing checks, like Adobe.

Your modem or router needs a firmware update

Your modem and router must have the latest firmware to work well. If the firmware is old, your internet may disconnect due to errors or registration problems.

Your internet provider usually updates your modem, but you should check if it has the newest firmware.

If you use a separate router, especially one not from your provider, ensure it is updated. Follow a guide to update your router’s firmware if needed.

You can check for modem updates by accessing its web settings. Follow these steps:

• Step 1: Open a web browser.

• Step 2: Type your modem’s IP address or login URL. You can find it on a sticker on the back or bottom of the modem.

• Step 3: Enter the username and password from the sticker.

• Step 4: Locate the firmware version, usually shown in the top-right corner of the settings page.

• Step 5: Search online or visit the manufacturer’s website to compare your firmware version with the latest one. You can search for the manufacturer’s name, model number, and “latest update.”

More Ways to Fix the Issue

Try these steps to solve internet connection problems.

Check Your Router Log

Your router records key events on your network. Checking these logs may help you find the cause of connection issues.

To access the router log, log into the router’s settings using a web browser. The location of the log varies by router brand:

1. Open a web browser and enter your router’s IP address or login URL. You can find this on a label on the back or bottom of the router.
   
2. Sign in using the administrator username and password you set up.
   
3. Locate the log section. Here’s where it might be for different brands:
   
   • ASUS: Advanced Settings > System Log
   • Linksys: Router Settings > Troubleshooting > Logs
   • NETGEAR: Advanced > Administration > Logs
   • TP-Link: Advanced > System > System Log

Router logs can be hard to read, but look for terms like “failed,” “malicious,” or “attack.” If you notice repeated entries, search online to understand their meaning.

Use the Windows Network Troubleshooter

Windows includes tools that can help diagnose and fix internet issues.

1. Click the Start button.
2. Open Settings.
3. Click Troubleshoot.
4. Select Other troubleshooters.
5. Click Run next to Network and Internet.
6. Follow the on-screen instructions to detect and fix problems.

Check Background Processes on Windows

Background programs slow down or interrupt your internet. Programs that use too much bandwidth or conflict with the firewall cause the issue.

Auto updates, cloud backups, and third-party apps often contribute.

To view background programs:

1. Click the up arrow in the taskbar to see some active programs.
2. Open Task Manager:
   • Press Ctrl + Alt + Delete.
   • Select Task Manager.
3. Go to the Processes tab.
4. Click the Network column to sort by network usage.
5. Right-click any suspicious process and select Properties to learn more.

If you suspect a program is causing issues, close it. If the internet stabilizes, that program is likely the problem.

Nothing helped. What’s next?

Contact your internet provider. They can find and fix broadband problems.

A technician may need to visit your home to check the tap on the utility pole, measure signal strength, run advanced tests, and handle other tasks you can’t do yourself.

Waiting for an appointment is frustrating, but it’s the best way to fix the problem for good.
