Start with the simple checks. Change one thing at a time so you can tell which step helped.
A wired test can reveal whether the slowdown starts at the broadband connection or inside the home Wi-Fi network. First, note what changed recently and whether the same issue affects another device. This helps separate a device-specific fault from a wider network or service issue.
Troubleshooting steps
Check the basics
Run the same speed test on the same device near the router and in the affected room. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Review the settings
If possible, connect a computer by Ethernet and compare the result at the same time. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Test one change
Repeat tests with other household downloads paused and more than one device. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Confirm the result
Compare results with your broadband plan and provider’s guidance, allowing for normal variation. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Helpful note
Keep notes of date, time, device and connection type to make a support report useful.
When to get more help
If these checks do not resolve the issue, contact the relevant device maker, internet provider or app support team. Include the exact model, software version, any error message, what you have already tried and when the problem began. Avoid sharing passwords, verification codes or private account details in a public forum.
For equipment that is hot, damaged, wet or making unusual electrical sounds, stop using it and seek qualified support. Do not open power supplies, batteries or mains-powered equipment.
Settings and menu names vary by model and software version. Use the manufacturer's current instructions for device-specific steps, and back up important files before making changes that could remove data.
