How do you fix Wi-Fi Dead Zones?

More Wi-Fi! Okay, it’s not that simple. Fixing areas of your business which are experiencing Wi-Fi dead zones actually requires more understanding of your business as a whole.  

• What do you do? 

• Where do you need connectivity? 

• Where are your current access points? 

• Is wired connectivity better for the use case? 

• What devices are you trying to connect from? 

• How old is your building? And what is the composition of your walls? 

All of these are important questions to ensure that the right solution can be provided. 

What are Wi-Fi Dead Zones? 

Wi-Fi dead zones are areas of a building or business site where wireless connectivity becomes weak, unreliable, or completely unavailable. For a business, a Wi-Fi Dead Zone can have wide ranging impacts on both your user’s ability to work, and wider impacts on your business operations. 

A dropped connection in a meeting room can interrupt a client call.  

Weak Wi-Fi in an office can slow employee access to critical systems.  

And poor coverage in a warehouse can stop handheld scanners, stock systems, and dispatch processes from working properly. 

Over the past decade, business’ reliance on cloud platforms, mobile devices, VoIP phones, video calls, connected equipment, and real-time systems has increased drastically. In 2023 Laptops accounted for 52% of the global personal computer market, a number which has only increased since that time. A 2025 report indicates that laptops are outselling desktops 3:1. Therefore, the importance of reliable Wi-Fi across your business estate has become an essential part of everyday operations for an increasingly mobile first workforce, without internet (or business network) connectivity people cannot work and a business’s ability to operate effectively decreases. When coverage is inconsistent, people are prone to work around the problem instead of fixing it properly. Over time, this can lead to slower processes, frustrated teams, and avoidable disruptions. It is important to remember that Wi-Fi technology has continued to evolve over the past 10 years. Since 2016 we have seen the introduction of Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7.  

 

Why do Wi-Fi dead zones happen? 

Wi-Fi dead zones usually happen because the wireless network has not been designed around the building and the way the business works. 

Sometimes the issue is physical. Thick walls, reinforced floors, lift shafts, glass partitions, metal racking, machinery, and older building materials can all weaken or block Wi-Fi signals. This is common in older offices, converted buildings, manufacturing sites, and warehouses where the structure itself makes coverage more difficult. 

Sometimes the issue is distance. If a wireless access point is too far away from the area where signal is required, devices may still connect and see Wi-Fi signal but either experience intermittent connection, or far slower speeds compared to other devices which can result in slow connectivity, dropped calls, or unreliable access to systems. 

Or, in areas with a large number of users the issue is usually capacity. A network that is built and configured could work well for a smaller team; however it will likely struggle once more users, laptops, phones, tablets, printers, scanners, and other connected devices are added. The Wi-Fi may technically be “available”, however but it may not be able to handle the number of people, devices and systems relaying data through it. 

 

Why should you tailor your network to your business needs? 

The right network setup must depend on your business needs, whether that be over wired or wireless infrastructure. At TwentyFour our Projects & Infrastructure Team work with businesses to assess their unique environments, how a business operates, the needs of the users and departments, and any other devices which require network connectivity. By doing so, we can ensure that your network operates, performs and meets your business needs without bottlenecks. 

Examples 

In a Legal or Accounting office, you may require Wi-Fi in areas support secure client meetings (including guest access), access to cloud-based applications, Teams calls, printers, and private offices or meeting rooms. If coverage is weak in client-facing spaces, it can impact both productivity and client experience. 

In the Manufacturing sector businesses can require a wide range of wireless uses dependant on the industry they work in. Wireless networks may need to support terminals throughout a manufacturing floor, production systems, monitoring tools, connected machinery, tablets and mobile devices (such as smart barcode scanners) across a more challenging environment. Metal surfaces, product racking, connected equipment, large machinery, production layouts, and operational changes can all impact signal quality for different access point locations. 

In Warehousing and Logistics, your Wi-Fi network often needs to cover large and varied spaces with multiple obstacles that can impact wireless connections. Continuous connectivity is likely needed across picking routes to be verified against internal systems, varied stock areas can present challenging environments with high and dense product racking, goods-in and dispatch zones will require users to verify stock in and out of the facility and much more. Some businesses may also need external-grade Wi-Fi so that users can stay connected to central infrastructure and databases while loading, unloading, scanning goods, or updating systems outside the main building. 

This is why your Wi-Fi infrastructure should be configured to your unique business needs, reducing the chance of Wi-Fi Dead Zones in areas you require connectivity. Your solution must be configured to match your building, the users, devices, use cases, and the areas where connectivity is essential. 

 

Is adding more Wi-Fi access points the answer? 

Not necessarily. The requirement for adding additional access points can heavily depend on the current infrastructure, the issues your users are experiencing and the use cases of the business. 

A common reaction to poor Wi-Fi by businesses is to just add another access point, booster, or extender. Whilst yes, additional hardware may be needed, placing equipment without proper planning and understanding of the use of the network in those areas can create new problems. 

Wi-Fi Access points that are badly positioned or configured can overlap, interfere with each other, or cause devices to stay connected to a weaker signal when a better one is available. As a result, this can leave users (and the business) frustrated, meaning devices can appear connected while still experiencing slow speeds or unreliable connectivity. Therefore, it is important that businesses work with professionals such as ourselves to ensure that any network changes benefit the business. 

In some cases, this can mean adding a new Wi-Fi Access Point and reconfiguring your network to ensure that users can easily move between access points for seamless wireless availability. In other cases, this could mean looking at replacing aging network infrastructure with newer devices or providing physical cable infrastructure for business critical devices. 

If your business has phones, tablets or laptops that are under 10 years old, likely they will be capable of WiFi 6, 6E or 7 connectivity that are capable of stronger connectivity, with faster speeds, better range and are less likely to be impacted by other environmental challenges. However, if your Access Points are more than 10 years old you will likely not be able to take advantage of this newer technology. 

A strong Wi-Fi network is not just about signal strength. It is about coverage, capacity, the ability to move around your network, enhanced security, and performance working together to provide seamless connectivity wherever you may be. 

 

How can you fix Wi-Fi Dead Zones? 

Before any work takes place, it is important that we work with businesses to understand the environment by conducting an in-depth Wi-Fi survey and understanding the use by teams across the network before choosing the solution. 

This can mean looking at the building layout, construction materials, existing access point locations, other network infrastructure (such as switches and internet connectivity), connected devices, user requirements, and the areas where Wi-Fi is most important to daily operations as beyond the technical Wi-Fi survey. By doing so, it allows us to identify where signal is weak and the cause. This can include; where interference may be occurring connectivity, where capacity is under pressure, and most importantly if the network no longer matches the way your business operates. 

In some cases, the answer may be simple. In others, we work with businesses to ensure that the solution fits their needs and can expand with their business. This can involve the addition of newer access points, replacing aging infrastructure, and in some cases replacing wireless infrastructure with wired to guarantee connectivity and performance for critical infrastructure. 

 

Do different Wi-Fi types matter? 

Different Wi-Fi standards, such as Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7, can affect speed, capacity, efficiency, and how well a network supports many connected devices. 

But it is important to understand that the newest Wi-Fi standard is not always automatically the right choice for every business. Swapping or adding a modern access point in the wrong location will not solve a poorly designed network. Any changes to network infrastructure should be carefully assessed to ensure that it works for your business. 

 

How can TwentyFour help your business to improve its Wi-Fi coverage? 

TwentyFour IT Services work with businesses throughout the UK to understand their operations. From our very first meeting we set out to “know our client”, this involves understanding;  

• Who you are.
