Learning how to check your internet speed can come in handy if you want to make sure you’re getting your money’s worth after splurging on a fiber connection. Knowing your true download and upload speeds can also be useful if your favorite streaming platform is lagging and you need to make your case to a representative of your internet service provider (ISP).

Luckily, doing an internet speed check is easy. There are many apps and websites you can use for free, and some even let you schedule network speed tests so you can identify patterns and know if you’re actually getting what you’ve paid for.

Why does internet speed fluctuate?

Before running an internet speed test, you should know that there’s a variety of factors that can impact your WiFi speed.

Time of day

The internet experiences the most traffic between the hours of 7 p.m. and 11 p.m. when a lot of people are back home after work, probably gaming, streaming their favorite shows, and browsing the web. ISPs have a limited amount of bandwidth so they struggle to meet customer demand during these peak hours, causing a log jam that results in slower speeds. This means that to get a true picture of your max bandwidth, you should check your internet speed during off peak hours.


While virtual private networks are great for making you anonymous on the web, the trade-off is a slower connection. To get an accurate reading, don’t forget to disable your VPN before running an internet speed test.

Network use

If you share your WiFi with a lot of people and a bunch of them are streaming movies, on video calls, or gaming, an internet speed test won’t produce accurate results. Wait until your network is seeing minimal use before you check it.

Q: Why don’t I get the connection speed my ISP advertises?

While most internet service providers attach data speeds to their tiered high speed subscription plans, it’s likely that you’ll rarely achieve that speed. In fact, most customers only receive a fraction of that advertised speed mainly due to the fact that internet companies are constantly trying to serve a lot of customers, resulting in significant network congestion. There’s also a host of factors in your home that can slow that speed down, including your router, modem, and VPNs. There’s a lot you can do to boost your WiFi speed, but if that doesn’t work, then it’s time to call your ISP.

Q: What is a good internet speed?

According to the Federal Trade Commission, anything above 25 Mbps is considered a good internet speed, as it’ll be able to support online gaming, TV and music streaming, and web browsing for a single device. However, if you have multiple people living in your household and simultaneously performing the tasks above, you’ll need a faster speed of around 100 Mbps to avoid issues.
