Why Is My Internet So Slow All Of A Sudden?

Internet connections slow down for a variety of reasons. Sometimes the fault belongs to your internet service provider (ISP) and sometimes its you. . It may be a little bit of both. Let’s take a look at some common causes of internet slowdown and get to the troubleshooting.

DNS Server:

In some cases, switching DNS servers can help speed up your apparent connection speed if your default Internet service provider DNS servers are slow.

When you connect to a website like google.com, your computer contacts its DNS servers and asks “What numerical IP address is associated with google.com?” It gets an answer back and connects to that IP address, which may be something like 216.58.193.78 and then connects to that address.

Typically, your DNS servers are provided by your Internet service provider. But, if they’re slow or overloaded, you may be able to get better speed by switching to another set of DNS servers. Google Public DNS and OpenDNS are both pretty popular.

Coax Splitters:

If you have cable Internet and you have coaxial cable splitters on the line going to your cable modem, these could be degrading your signal strength and leading to slower Internet connection. Splitters vary in quality, and a bad, cheap one could lower your signal strength much more than a higher quality one would. A large number of splitters could cause a problem, too.

Your Device Might Be the Problem:

If there are no problems with your router and/or modem, then the problem may lie in the device you are using…whether it be a laptop, smartphone, tablet, or even a smart TV.

· Power Saving Mode. If your device is on power saver mode, then it might mean your network adapter is not transmitting or receiving optimally.

· Update Your Network Drivers. Make sure that your network adapters are constantly updated, to avoid malfunctioning and errors.

Wi-Fi Might Be the Problem:

In some cases, it might not be your internet connection that is slow—the problem might lie with your Wi-Fi.

Let’s say that your internet service provider is offering you 100Mbps, but for some unknown reason/s, you just aren’t hitting those speeds!

The first thing to do is to pinpoint where the trouble lies.

Giving Your Router a “Breather”:

The very first thing you should do it to simply restart the router. Unplug the power cable of your router and wait around 15 seconds or so before plugging back the power cable of your router. It sounds so simple, but usually does the job and fixes a number of problems.

Upgrade Your Router?

It is possible that your Wi-Fi router might not be able to handle the given speed. If this is the case, then you might need to upgrade your Wi-Fi router to fully maximize your internet subscription.

Too Many Users Are Connected To Your Wi-Fi Router:

Another reason that might be causing your internet to slow down is that there are just too many users connected to the router. What happens is that all the different connected devices are likely pulling bandwidth to/from the internet, thus slowing down the internet speed.

Normal browsing does not really affect internet speed—unless, of course, there are two or more users hammering the connection doing things such as downloading huge files or watching high definition videos at the same time. These activities would really affect the network and bandwidth, thus slowing overall internet speed.

Location of your Wi-Fi Router:

If you are on a wireless connection and your internet is slower than usual, one of the most common problems is that the location of your router might be negatively impacting your wifi speed and coverage.

Two of the main causes of this are:

  • the distance, and
  • certain obstacles, like walls and doors

Background Programs Using Bandwidth:

Another possible reason for your slow internet is programs that are running in the background and using up your internet bandwidth. While most of these background programs probably do not take up much bandwidth on their own, together, these can really add up.

Another possible culprit of slow device (and we’re moving into the operating system of the device as a whole, rather than just looking at the internet speeds here), are programs, whether you know about them or not, hogging your system resources.

Heavy Traffic On Websites:

If a website is trending, chances are there are a lot of people trying to access that website as well. If this is the case, check your internet speed and open up a couple more websites. If the speedtest.net shows your subscribed speed and other websites are loading fast as well, then most definitely the slow website is dealing with heavy traffic at the moment.You can either wait or come back later.

Too Many Routers on One Channel:

If too many routers in one area are connected to the same channel, it is possible that these routers are conflicting with each other’s signals. However, it is possible to change the current channel that you are on and choose another one that has lesser routers connecting to it.

Wifi Interference From Other Appliances:

There may be other, non-wifi devices, that may be impacting your wireless signals. These include, but are not limited to, baby monitors, microwaves and cordless phones. They share the same frequencies as your wifi network (they use unlicensed frequency bands).

Also, furniture and the aesthetics of your home can impact signal. Don’t place your router near metal sheeting!

Have an Unsecure Connection:

If you suspect there are other people—apart from you and your household—using your internet connection through your Wi-Fi, best thing to do is change your password. In fact, you should do this regularly, regardless.

Internet Traffic “Rush Hour”:

Your internet may slow down at certain times, such as early evening or weekends when all the users in your neighbourhood is using the internet at the same time. This causes “connection congestion” and also affects websites that users are trying to connect to as well.

Call Your Internet Service Provider (if you haven’t already):

If you have tried everything to speed up the connection to no avail, then it’s time to pick up the phone and call your Internet Service Provider right now.
