Do you have DSL or Cable?

Rural or Urban?

Upload - Download or both?

Sometimes WiFi signals from close proximity Wifi Routers can interfere with each other. Default channels get "congested". Try changing the channel to a higher band.


This may not necessarily fix your problem but changing bands has helped my configuration in the past in dense environments and it is a low hanging fruit item.

If you router is a few years old, you might want to explore replacement options, especially if CenturyLink allows you to bring your own router/modem device.

Check that everything is plugged in securely.

Can you log in to your modem using IP codes? I am assuming your ISP has already checked this if they say nothing is wrong with the modem/router.

What does CenturyLink say if you call them during the downtime? If you can, that's when I would call them: while the problem is occurring.

They insist that nothing is wrong, as a direct link via Ethernet to a computer shows the speed and strength to be as provided.

or your modem/router if combined.

Google your existing modem and router and see if there are known issues with CenturyLink and perhaps get a new one, as others have advised already. Just make sure that you do a bit of research.
