Don’t suffer with a poor internet connection. Find the root cause of your on-line issues.

How to Test WiFi Signal Strength in your Home

Welcome to our blog post on how to test WiFi signal strength in your home. In this post, we will be looking at the free online tests that you can run.  As well as taking a closer look at the most meaningful measures of WiFi, signal strength, consistency, and throughput. And how that translates to dropouts, lag, and buffering on your network.

The fastest and simplest way of checking the quality of your wireless network is the WiFi signal indicator icon. The more bars you have the stronger the WiFi signal is being received by the device. However, signal strength alone is not an indication of quality, a user can still experience a frustrating time while trying to get things done online.

What to Test on your Network

When deciding how to test WiFi signal strength in your home lets concider the common issues. These can be characterised by high network latency (lag), weak signal (Poor reach), and or low throughput (speed). For example, when you are gaming online with high latency. You tell your character to walk, there is a delay before they move. Or you’re connected to video calls and suffering poor video and audio quality. This is lag and is the symptom of high latency. Latency is how fast data travels to a destination (server) and back again. i.e. the total round trip of a packet of data.

A weak signal is normally easily identified by the signal strength bar indicator. Problems can be intermittent depending on the distance from the nearest WiFi point or router. Other environmental conditions can affect this also. This is discussed in more detail in another post 4 Causes of poor WiFi in your Home.

If your network isn’t fast enough to meet the demands of its users at any given time then you will experience buffering. This is the reason you are waiting for Netflix to download enough of the stream before it can start or resume the program. The network speed test measures the time it takes for a certain amount of data to travel from a destination i.e. a server to your device this is the download speed. The upload speed checks how quickly your device sends data back to a server. 

How to check the Broadband Service to your Property

The first step in this how to test WiFi signal strength guide, is to establish a base line. This is done by checking the throughput and jitter you are receiving into your property. There are many free browser based online, speed tests you can use. Look out for one that measures the download/upload speeds and jitter. Cloud Flare is an example of a site that measures jitter, there are many others out there to choose from.

Many factors may affect the results of your speed tests. For example the device, time of day, and the speed test tool can all add variables. That’s why it’s best to keep these things consistent if possible. Use a laptop if that’s possible as you will be able to test your router directly to get a baseline as to what speed and pings you are receiving straight to your property from your ISP (internet service provider).

First of all plug an Ethernet cable from your laptop directly into your router and run the online speed test. 

Check that the download speed is reasonable for the broadband package that you have. For smooth gaming and video calls, a jitter of no more than 30ms is adequate. The results will vary depending on the time of day so it’s best to take an average over a few days. If you’re consistently not getting the required results then contact your ISP for a diagnostics session.

How well is your Internet Distributed around your Property?

Now you have a baseline to compare your results to. You will need to know how to test WiFi signal strength in and around your property. The next step is to unplug your laptop from the router and connect to your WiFi network. Move around your house making a note of the upload, download, and jitter readings in various locations. If you suspect you have WiFi black spots then run the test from these locations. Where the download and upload are much less in certain areas then you know that you have problems with the quality of the signal or signal reach. A high jitter in the area means you have a problem with network interference, blocked signal, or packet loss flooding the network.

If you are experiencing a big loss in speed or the jitter is higher than desirable. Check which access point you are linked to. Your network might not have the roaming feature or it isn’t handing off correctly. Or you might not be connected to the closest access point.

How to Test WiFi Signal Strength – Pinpointing the Bottlenecks

A slow or jittery network can still show full bars on the signal indicator, this isn’t always the full picture. If you’re experiencing issues with your internet connectivity, it’s worth spending the time to find out where your bottleneck is.  

If the problem is within your home, its time to review and possibly upgrade or expand your existing network infrastructure. Mesh systems typically do a good job of boosting the signal strength but not necessarily the signal quality. Expanding your WiFi reach using boosters increases latency and reduces throughput at each node. Distributing a more and more distorted signal at each node.

Just because you are located further away from the router doesn’t mean that you should suffer from poor service. 

Hardwired access points will distribute internet more effectively. Meaning you can expect to see throughput and latency at speeds much closer to what is received to your property.

In this Post we will be looking at the most Common Reasons for Poor WiFi Signal Coverage in your Home

If you’re experiencing poor WiFi signal coverage in your home. It can cause a lot of anxiety when faced with that important video meeting, home-schooling lesson or settling down to stream your favourite TV series. In this blog post we will discuss some of the reasons behind why your WiFi is not up to the job.

Poor Wi-Fi in your home
Learn the possible reasons why your internet connection isn’t up to speed.

ISP issue

ISP (Internet Service Provider) This is a problem with the service to the door. Typically when the problem occurs, it affects every device on your network at the same time. Check the router to see if the service light is solid green when your network is faulting. Another way to diagnose a service fault is to sit next to the router with an Ethernet cable. Plug your laptop directly into the LAN port to see if you get the same problem on a direct connection to your router. Contacting your ISP for a diagnostic call should sort the issue, otherwise consider a 4 or 5G backup router and sim card.

Building Materials & Obstacles

If you are experiencing intermittent low WiFi signal, dropouts, and disconnects. The issue could be the construction of the building. Some properties soak up WiFi this is due to the construction materials. Masonry, timber, and concrete walls are more problematic for WiFi signals. Water and metal are also notorious for interfering with WiFi. Aquariums and under-floor heating can affect how far your WiFi signal will travel. It is possible that moving your router to another location may improve the performance of your network.

Interference from other Wireless Networks or Devices

WiFi poor network speeds and lag can be caused by signal interference from other WiFi networks.  These can be other networks in your home, such as your home entertainment media system or externally if a neighbours wireless network is configured to the same frequency.  Sources of signal interference in you home can be incorrectly set up SKY Q systems or Mesh networks that are oversaturating the signal in your home.

Devices that use blue tooth, baby monitors, remote alarms, microwaves and TV’s can cause intermittent disturbance in the frequency range of most WiFi networks.

Large or Irregular Shaped Homes 

Where WiFi signal is none existent or very weak with distance from the router, especially upstairs. The issue is likely to be that the signal cannot extend as far as you need it to. Similarly, if your home is an irregular shape with lots of external walls. Your WiFi signal may not be able to penetrate the thicker walls.

Do you need a Home Network to Resolve a Poor WiFi Signal Coverage at Home?

There are some straight forward solutions you can implement to remedy your poor WiFi signal coverage in your home. However, if your home is constructed with WiFi impermeable materials, contains signal soaking obstacles or is large or an irregular shape. You may have tried the WiFi extending products such as powerline adapters (home plugs), WiFi boosters and extenders without success. Then the gold standard solution is a home data network installation.

A correctly planned and configured home network will extend wireless signal and work around the obstacles. It will provide internet connectivity at the range, reliability, security and speed to support all your on-line devices. There are two main home network topologies to consider; either a mesh network or a star wired ethernet backbone with wireless access points. We will discuss the relative merits of each of these types of networks in more depth on a future post.

Fantastic job overhauling the home network. Having tried multiple solutions to conquer WiFi over the years, Chris and Jamie were able to come in, do the analysis and recommend a real world solution. Using trusted branded equipment, the end result has been fantastic with end to end coverage. If you need a network solution that 'just works' rather than the sales hype you get from the usual providers, then I can't recommend highly enough. Give them a call, you won't be disappointed!

Netlinx installed network cabling and WiFi access point installation throughout our home. From the first point of contact, they were extremely helpful, efficient and informative. On the day the work was completed, they undertook a number of additional tasks which had not previously agreed without so much as raising an eyebrow, and their aftercare has also been excellent. An issue subsequently arose with our network provider, and not only did they take the time to guide me through a number of tests to try and identify the issue, but also spoke with the engineer that subsequently attended at my property to remedy the problem. I would not hesitate to recommend Netlinx: they are extremely professional and thoroughly deserve a 5 star rating!
