What to Do If Your Internet Is Suddenly Slow? 9 Ways to Find the Problem

Is your internet suddenly crawling? Before you panic, work through these nine steps to identify and often fix the problem yourself.

1. Run a Speed Test

Use a reputable speed test service to measure your current download and upload speeds. Compare the results to the speed you pay for. If the numbers are far lower, you have a problem.

2. Restart Your Router and Modem

Unplug both devices, wait 30 seconds, then plug them back in. This clears temporary glitches and is the most common fix.

3. Check Cables and Connections

Inspect all cables for damage or loose connections. A frayed Ethernet cable or a coax cable that is not tight can degrade signal quality.

4. Test on Multiple Devices

If only one device is slow, the issue is likely with that device, not your internet. Try another phone, laptop, or tablet to see if the slowdown is widespread.

5. Reduce Interference

For Wi-Fi, move your router away from microwaves, cordless phones, and thick walls. Switch to a less crowded channel in your router settings if possible.

6. Check for Bandwidth Hogs

Other devices on your network might be streaming, gaming, or downloading large files. Pause those activities and retest.

7. Scan for Malware

Malware can consume your bandwidth. Run a full antivirus scan on all devices.

8. Update Firmware

Outdated router firmware can cause performance issues. Check the manufacturer's website for updates and install them.

9. Contact Your ISP

If none of the above works, your internet service provider may be experiencing an outage or a line issue. Call them with your speed test results and the steps you have taken.

When to Call a Professional

If you have tried all these steps and still have slow internet, it is time to call your ISP. They can run remote diagnostics and send a technician if needed.

Remember, a slow connection is rarely permanent. With these steps, you can often restore your speed without outside help.
