How does the Optimum speed test work?

This Optimum speed test starts by identifying your Optimum connection and then selecting the speedtest server nearest to your location.

When you click the GO button it’ll send packets of information from the speed test server to your device.

The Optimum speed test is by powered by Ookla and measures the ping (latency), download speed and upload speed from your device and the test server.

The time that it takes this packet to go to and return from the server establishes your Optimum internet connection speed.

How accurate is the Optimum internet speed test?

This Optimum Speedtest is powered by Ookla which one the most popular broadband connection speed test and provides accurate and consistent testing experience and results.

By automatically selecting a speed test server closest to your location, this eliminates latency and bottlenecks that may skew performance metrics.

Ookla has a global network of over 10,000 speedtest servers in over 190 countries.

To improve the accuracy, it is recommended to run the Optimum speed tester from a device connected directly to the Optimum gateway modem or router.

This will help provide an accurate reflection on the performance of the Optimum internet connection and help rule out the wireless network.

If you are unable to connect your device directly to the Optimum modem or router, make sure that the device you are running the test is as physically close the modem or router as possible. Also run the speed test at least twice and from two different devices to make sure that the problem is not on the device.

What do the results from my Optimum speedtest mean?

Whats is Ping?

Ping is sometimes referred to as latency which in internet connectivity terms means the time (or delay) it takes for data to travel from one device to another. In this instance, from your device using the Optimum broadband connection to the nearby server.

Ping sends information to another computer (in this case, the speedtest server) and measures in milliseconds (ms) how long it takes to get a reply back.

If the other computer is far or the network is busy it will take more time to receive a response and therefore the ping value will be high.

This Optimum speed tester will automatically choose a speedtest server nearest to your location which will eliminate latency and bottlenecks which can skew performance metrics.

A fast ping (low ms value) means a more responsive Optimum internet connection.

What is a good ping rate?

A typical ping rate to a device across the same city should be lower than 20ms. A good ping rate between cities you would expect to see ping values between 30-60ms, and between continents that figure can be over 200ms.

The speed test above  will show you the location of the test server so that you can determine whether your ping result is good.

What is Jitter?

All data (e.g. an email, image, video, voice call, etc) is transmitted across the internet as a series of packets. These packets typically move at a constant rate and are rebuilt back together at the destination device.

Jitter is the rate of delay during the transmission of the packets.

Try to think of it like running a tap and then increasing or decreasing the flow rate of the water coming out. When the flow rate becomes irregular (because of the increasing and decreasing), the Jitter value increases – which is not good.

You don’t ordinarily notice jitter because networking devices can smooth it out but you will notice  jitter whilst on internet video and voice calls because the connection will momentarily disconnect or break up.

Likely causes of Optimum slow internet speed

Optimum Internet Speedchecker - Slow Internet speedThe are a number of reasons why the Optimum internet connection is not performing. While we cannot address each and every possible cause, we have listed a number of likely causes.

Depending on your Optimum internet setup, some of the suggestions may not be applicable in your case. Hopefully they may trigger food for thought or get you heading in the right direction to resolve your fault.

Is it the Optimum broadband internet that is slow or could it be your device (PC/laptop/phone)?

You may need to check how many apps are simultaneously running on your device that could be using your system resources (mainly RAM memory and CPU) and your Optimum internet bandwidth.

If you are on a computer, you can use the task manager to see your processor and memory usage.

On any other device you could try restarting the device which should hopefully kill all apps that may have been running in the background.

Re-run the Optimum speed test on your PC and your phone to see how the speedtest results compare between the 2 devices.

Hopefully the will give you some info to work with in terms of whether the problem lies with your device or the Optimum internet connection.

Is the Wifi connection the problem?

The cause of the issue may be your Wifi network connection and not the Optimum internet connection.

You can rule out the wireless network being the cause of the issue by connecting your PC directly to the Optimum internet modem or router using a network cable and run the Optimum speedtest again.

If performance is better when you are connected using a cable then this proves that the fault may be with the wireless network.

Possible things to check are:

  • Are the WiFi channels you are using for your wireless network network (SSID) overlapping with your neighbors?
  • Is your Wireless frequency congested. Maybe you should consider switching to 5Ghz?
  • Could the Wi-Fi network signal from the modem or router obstructed?
  • Does your performance get better when you’re standing directly infront of the Optimum Wifi network modem/router?

Number of devices connected to your internal network

Every device that is connected to your internal network is sharing the same Optimum internet connection.

If you have multiple devices browsing the internet, streaming movies, streaming music, downloading or uploading files, video conferencing, etc, this will have an impact on the performance on your Optimum internet connection because the bandwidth has to be shared.

Are you aware of how many devices are connected to the Optimum internet connection? Do not forget about all the smart home devices, CCTV cameras, doorbell cameras, alexa/google home bub or other similar devices that are continually connected.

Who is connected to my Wi-Fi network?

Have you checked that your Wi-Fi network password has not been compromised? Do you have an open Guest wireless network?

Nearby Neighbors could be on your Wi-Fii network and using up all the Optimum internet bandwidth downloading, uploading, streaming or running peer-to-peer file sharing over your Optimum internet connection. Worse still, they could be carrying out unlawful activities.

There are two apps that you can use to scan your Wi-Fi network to check who’s connected:

Both applications will scan your wireless network and display a list of the devices connected.

Alternatively, you can log into the Optimum wireless router to see who is logged in.

Check out this guide on how to use these applications

Wi-Fi signal strength

If the PC,laptop is not picking up a strong signal it will affect on the throughput, speed and internet performance regardless of how fast your Optimum internet connection is.

Situations that can affect the wireless signal are;

  • Walls, doors or floors between your device and the Optimum internet modem or router
  • Household appliances like baby monitors and microwaves
  • Overlapping Wifi network signal from your neighbours
  • Long distance between the device and the Optimum internet modem or router.

Do I need a wireless signal booster for my Optimum broadband internet?

If you discover that you have wireless blackhole at your property, a wireless signal extender also know as a Wi-Fi booster is the solution to boost your signal strength across the house.

The wireless booster simply picks up your existing wireless signal as it is starting to become weak and then re-transmits the Wi-Fi network signal at a stronger rate to extend its reach.

Locate the wireless network booster/extender where the Wi-Fi network signal from the Optimum broadband internet router or model is beginning to become weak. Roughly where your Wifi signal drops down to two bars. You can use your phone to determine where this is.

End device health

Viruses or malware can slow your device and consequently your performance on your device. Viruses and malware could be working quietly and concealed in the background download and uploading data and thus slowing the performance of the whole internal network down.

When is the last time you ran a full Virus and Malware check on the device?

Run a virus/malware checker on your devices to rule this out.

When was the last time your Optimum broadband internet modem or router was restarted?

Just like other Internet Service Providers, Optimum’s broadband infrastructure is frequently being updated to support new features and changes in technology. Likewise, the internet routers or modem at your home will also occasionally need an update to support changes in the Optimum broadband internet network.

The update could be in the form of a software update or an upgrade of the physical Optimum modem/router hardware to a newer version.

You may be able to perform the software upgrade by logging into the Optimum modem/router. If you cannot do this or are not confident doing this, contact Optimum and they will be able to either {do it for you or talk you through it.

The type and age of device

The latest PCs, phones and other internet enabled devices will be generally faster than old devices due to advancements in networking technology and protocols.

Do you experience the same problems or newer devices?

Is the issue external to your home?

This is probably the most likely reason for Optimum internet issues. The are miles of cables involved to deliver the Optimum broadband internet connection to your property.

The issue may be with the physical connection that comes into your property and goes into the modem or router in your house.

You should contact Optimum who should be able to carry out the relevant line tests to see if there’s a issue on the Optimum internet connection.
