You will identify reasons and solutions simultaneously.

Find out the answer to why does my Internet speed fluctuate

Internet fluctuation meaning

When it comes to Internet fluctuation, issues are disparate. 

Thus, we focus on the packet level only. In this level, there are three certain problems – lost, postponed, and jitter (especially a Voice over IP connection). 

While packets are arriving, nothing is assured that VoIP connections do not get stuck due to UDP/IP protocol. 

This point is called Internet fluctuations. 

A small issue might cause poor performance in a network and influence application delivery. 

Proper measuring and analysis equipment can quickly find out the reasons for such fluctuations. 

They also support network administrators to prevent unexpected errors. 

Walk through the problem and fix it

Can fluctuations be caused by an outage?

Outages are one of the biggest reasons for Internet fluctuation. Moreover, system services and maintenance updates could cause Internet speed changes. 

According to experts, a system outage possibly prevents Internet speed. 

This is a popular circumstance to accelerate the Internet speed problem. Of course, we should find a solution to repair it. 

Reasons my Internet speed fluctuate

Your Internet speed does not remain for a long time, it is not easy to recognize and know where to begin. 

There are various possible reasons for your concern “why does my internet speed fluctuate so much?”. 

Factors causing Internet fluctuation

Types of connection

The Internet speed in your home or office is the consequence of the type of connection. And the network has several categories making you surprised and curious. 

  • DSL (Digital Subscriber Line): the network receives a copper wire in order to link a broadband connection. The speed can work up to 3Mbps. 

  • ADSL (Asymmetrical Direct Subscriber Line): like DSL, the network also uses copper wires to start the process. Nevertheless, it refers to download speeds and less focus on upload issues. ADSL is so widespread and a lot of providers offer this service. For those who need to upload heavy and large files, they will spend much time enhancing the upload speed. Gamers also feel exhausted by the same situation. 

  • Cable connection: coaxial cables improve high-speed loading than copper wires (used in both DSL and ADSL). Thus, these cables convey data quicker and save much time when uploading or downloading big folders. The downside of this connection is that several households have similar coaxial cables, so they do not have a high-speed network in peak time. 

Cable connection

  • Satellite: a satellite does not require cables and wires to work. The database is moved freely in the air. A satellite connection will move the data to the intended destinations. Though satellites are popular these days, the connection is so low because of long distances. The network might catch broadband speeds, but the weather and other outside situations can affect the transfer.   

  • Fiber: fiber is the best connection in the modern world. Fiber-optic cables could express a big database in a short time. Additionally, the environment does not reduce the quality of these cables no matter the bad or good weather. 

Fiber is the best network

Router position

A router position might become the cause of the low speed of your Internet that you are getting stuck. 

Avoid placing all modems near kitchen electronic devices, walls, and other signal blockers. 

You should not put routers on the floor because other signals might move along the surface and prevent the signals from your gadgets. 

Router settings

Do the router settings probably improve problems in your devices? 

This is an opportunity to detect potential troubleshoots. Then, you can boost the Internet speed and get rid of the fluctuation speed completely. 

Most modems have a 2/4 GHz Wi-Fi channel. Unfortunately, this channel is quite busy. 

If other households are using extending channels, the bandwidth is also busy. 

As the result, your Internet connection is poor. 

Additionally, RTS (Request to Send) threshold settings in your routers could be too low. 

Improving them to the maximum level (2346) and changing the threshold at once, may support routers' stabilization. 

Did you upgrade your Internet bandwidth? 

Remember to check the database packet size settings in your routers because these settings might limit the amount of your data that allows you to use it. 

Make sure that your gadget does not have below the Maximum Transition Unit. 

Throttling

The Internet service company sometimes adjusts your Internet speed if you use an overloaded database limit. 

This change is one of the factors causing why does my comcast internet speed fluctuate.  

Malware

Malware is usually an unexpected guest to your devices, applications, and even routers. 

Why does my internet speed keep fluctuating? These guests may be the underlying cause.
