Is it always my internet provider's fault when evenings are slow?

Not always, but often. Peak-hour congestion is built into most home internet plans. If you can prove with speed tests that mornings are much faster than evenings, your provider may offer to upgrade you to a business-grade plan or a newer technology like fibre. It is worth asking.

Would a new router fix this?

Sometimes, especially if yours is more than five years old. A new router gives each device more headroom. It will not help if the actual internet coming into your house is slow during peak times, but it is worth checking. We can tell you honestly which is the real problem.

Do smart TVs and doorbells slow down my internet?

A little bit each, constantly. On their own they are fine. The issue is that modern homes often have 20 or 30 connected things that all chip away at bandwidth. When several big downloads happen at the same time, they compete, and the whole connection feels slow.

Why is my internet slow at certain times of day?

Internet that is fine in the morning and useless in the evening is one of the most common complaints we hear. The cause is usually one of a small number of things, and most are fixable.

Quick Answer

If your internet slows down every evening at about the same time, the cause is almost always peak-hour congestion on your street or too many devices in your home. If it is slow at unpredictable times, it is more likely a background download or an ageing router. The fixes are different for each, so work out which pattern fits.

The six most common causes

Work through these and see which one matches your pattern. The good news is most of them are fixable without calling your provider.

Peak evening hours on your street

Most home internet connections share bandwidth with your neighbours. From about 6 pm to 10 pm, everyone streams, games and scrolls at the same time. If your internet is fine in the morning and slow at 8 pm, this is almost always the reason. A mesh Wi-Fi system will not fix this, because the bottleneck is outside your home. Upgrading your plan with your provider is the only real fix.

Too many devices connected at once

Modern homes have 15 to 30 connected things: phones, laptops, TVs, game consoles, doorbells, smart speakers, thermostats. All of them use a little bit of bandwidth even when you are not actively using them. At peak times they compete. If the slow periods match when everyone in the house is home and online, this is likely part of the cause.

Neighbouring Wi-Fi on the same channel

Wi-Fi uses invisible channels like radio stations. If your router and several of your neighbours' routers are all broadcasting on the same channel, they interfere with each other. This shows up most in dense neighbourhoods and apartment buildings. Modern routers auto-switch channels when they get overwhelmed, but older routers do not. Our Wi-Fi setup service includes checking this.

Your provider is slowing you down

Some internet plans have a monthly data cap, and once you exceed it the provider throttles your speed until the next billing cycle. If slow internet seems to start a week or so before your bill and then recover, a data cap is the likely explanation. Call your provider and ask what your monthly allowance is.

Background updates downloading silently

Windows, Mac, iPhone, Android, smart TVs and even game consoles all download updates in the background, often several gigabytes at a time. If a big update is coming down, it can hog your whole internet connection for 20 or 30 minutes. Check if any device shows an Updating or Downloading message.

An old router struggling with modern speeds

Routers made more than five years ago were not built for today's speeds or today's number of connected devices. Even if your provider has upgraded your plan, an old router caps how much of that speed actually reaches your devices. This is the single most common hidden cause and the one most worth checking.

How to test when the slowdown is actually happening

Next time your internet feels slow, open a web browser on a phone connected by Wi-Fi and go to fast.com. It will show you your real download speed in a few seconds. Note the time and the number. Do the same thing the next morning when things feel fast. If the slow number is less than half the fast number, you have a real problem. If they are close, it might just feel slow because a specific website is struggling.

When to call us instead

Call us if the slow times are disrupting your work or calls, if you have been on the phone with your provider and got nowhere, or if you would rather have someone check the whole setup in one calm visit. We handle Wi-Fi and internet problems across Ajax, Pickering, Whitby and Oshawa as part of our Wi-Fi and home setup service.
