Don’t worry, we’ve all been there. These trips can help you solve the most frustrating annoyance of the modern era.


Why Is My Internet Slow?

At least everybody has dealt with slow internet. Back in the early days, circa 2000 to 2010, things were just slower, so we were all used to sluggish download speeds. But today, if your internet is slow, and you’re paying for fast internet, it is usually down to one or more fixable errors.

The most common reason for a slow internet connection, however, is that you went with a poor internet provider or a low bandwidth package. In order to have fast internet, you need lots of bandwidth. If you lack bandwidth, you’ll struggle with streaming and connecting multiple devices to your home WiFi network.

The easiest way to fix this, if you live in an area that supports it, is to switch to gigabit internet – this is fiber-powered internet and it will let you download up to 1GB of data per second. This means it has A LOT of bandwidth – 10X that of 100Mbps internet – and this makes it perfect for future-proofing your home.

And the best thing about gigabit internet? It isn’t even that expensive, as you can see inside our guide to the Best Gigabit Internet Plans – you can be up and running for as little as $49 per month.


And gigabit internet will let you seamlessly stream 4K UHD content and run a million and one devices on your home network without it ever down. This is the power of having MASSES of bandwidth. You will never have to deal with slow internet again. Ever.

And while this is very much a first-world problem, it’s annoying nevertheless – especially if you rely on the internet to keep in touch with vulnerable friends or family in this COVID world we live in or need it to work and thus maintain your livelihood.

But what if you cannot switch ISPs? What if you’re stuck with your current plan? No worries, we got you covered here too. The good news is, if you have slow internet it’s relatively easy to track down the problem. Below, we’ve laid out five ways to do just that.

Reboot Your Modem/Router

The first thing you should do is check your modem/wireless router. Note that your modem is probably built into your wireless router, so they are one and the same. The only exception to this is if you have had the same internet hardware for close to a decade. In that case, you might have a separate modem and wireless router, though it’s unlikely nowadays.

Ninety percent of all internet problems can be solved by tinkering with your wireless router. Wireless routers are often the source of slow internet speeds because they can sometimes get overloaded with data.

The good news is, if this is the problem, it’s easy to fix. Try doing one or both of these:

Chances are this will have fixed most internet connection problems.

Check For Coaxial Splitters

Speaking of roueters…if you get your internet via a cable connection, the router will be connected to a coaxial cable coming from your wall. However, sometimes when a technician installs your router, they’ll use a coaxial cable splitter.

This cable splitter ensures data can run to two different sources: your TV and other devices like a router. However, the cable splitter can act as a bottleneck, slowing your data transmission.

To check if the cable splitter is the source of your trouble, unplug the cable splitter and connect your router right to the coaxial cable coming from your wall. If your internet speeds up after this, the cable splitter was likely the source of the problem.

Don’t Overwhelm Your Network

Another big reason for slow internet speeds? More than one device is downloading a MASSIVe amount of data at the same time. This will definitely slow down all devices on your network.

Check if this is the case is easy. Just ask everyone else in the household if they are streaming or downloading large amounts of data. If one person is streaming Netflix 4K video and another is downloading a 100GB game installer, it’s no wonder your browsing speeds are slowing.

Switch DNS Providers

A DNS, or domain name server, is a fundamental part of the internet. When you type in a URL, such as www.knowyourmobile.com, your computer sends this to your router, which sends it to your ISP which sends it to a DNS server. This DNS server converts the worded URL address into the numeric IP address of the site you are trying to access. This all happens in a split second.

But because DNS’s are constantly doing this for billions of web addresses, they can become overloaded, which can slow down connection speeds. If the DNS is the source of your problem, switching to a new DNS could help.

There are tons of DNS’s you can tell your router to send URLs to. The most popular include 1.1.1.1 and OpenDNS.

Get a Mesh Wi-Fi System

Finally, it’s worth noting that your internet speed could be slow because of your location relative to your wireless router. The farther away you are from it, the weaker your signal will be, and thus the speeds will be slower.

If your house is very very large, this could be the main problem. So, how to get around it? Invest in a mesh Wi-Fi system. This is a system that puts multiple wireless base stations around your house boosting your internet signal – and thus speed – all over it.


Or, if none of these worked, just switch to a faster internet provider.
