WiFi problems are frustrating—especially when your video call freezes or your internet just stops working in certain rooms. If that sounds familiar, you're not the only one dealing with it.
Experts say your WiFi signal should be at least –67 dBm to keep things like streaming and video calls running smoothly. Anything weaker than that, and you’ll start to notice slow speeds, dropped connections, and other annoying issues.
This guide breaks down the best ways to fix those problems. You’ll learn how to boost WiFi signal using simple tips that actually work—no confusing tech talk or expensive upgrades required.
Businesses can’t afford to operate on a weak WiFi signal. When your internet connection drops or slows down, everything else grinds to a halt—video calls freeze, cloud systems lag, and your team ends up wasting precious time just trying to reconnect.
Whether you're running a high-traffic online storefront or managing client emails in real time, a weak WiFi signal chips away at productivity and customer trust.
Knowing how to boost the WiFi signal directly affects how fast and stable your wireless network feels. The stronger the signal, the better the speed, coverage, and overall WiFi performance.
A strong WiFi signal lets you manage software updates without stalling, host HD video calls without interruption, and support multiple devices—especially important when you're running dozens of laptops, phones, or smart systems at once.
The physical placement of the router, the type of equipment you use, and the signal interference from thick walls or baby monitors—all of these affect the signal strength your business depends on.
Many offices or work-from-home setups rely on a single router, which can create dead zones and slow internet speeds in rooms far from the main access point.
Without range extenders, mesh Wi-Fi systems, or proper cabling like Ethernet cables, teams working in those areas often experience slower connections or dropped signals.
In short, a strong WiFi signal means:
WiFi works by using radio waves to transmit data from your router to your device and back again.
That router is connected to the internet via a modem—usually with an Ethernet cable—and it sends out a wireless signal across a certain range, creating a WiFi network.
Devices like laptops, smartphones, and smart TVs connect to this wireless signal to get online.
The signal strength you receive depends on a few key things: how far you are from the router, how many obstacles (like thick walls or metal surfaces) are in the way, and how much interference is coming from other wireless devices nearby.
This is why you might notice better internet speed when you’re close to your router and worse performance in other rooms.
When you know how to boost the WiFi signal, you would know that the WiFi network signal strength drops with distance and interference. Mesh systems and Wi-Fi extenders help extend your signal across every room by relaying and amplifying the existing signal.
Still, the router’s signal quality and firmware updates play a big role in how consistent your WiFi speed and coverage are.
Let’s break down 10 specific hacks that can help boost your WiFi signal and strengthen your internet connection around your home or office.
Where the router is placed makes a big difference. A router shoved into a corner, under a desk, or inside a closet will have its signal blocked by furniture and walls.
Keeping the router in an open space—ideally in the centre of your home or office—allows the signal to travel evenly in all directions.
If your router is too far from where you use the internet most (like a work desk or media room), the signal will be weaker.
Position it away from thick walls, appliances, or baby monitors, which can block the signal or cause interference. Placing the router high up—like on a shelf—also helps extend the signal further.
If you’ve got a larger space or multiple floors, a single router probably won’t cut it. That’s where mesh Wi-Fi systems come in.
These systems use multiple nodes placed around your house or office to create one seamless wireless network, eliminating dead zones and weak spots.
Unlike range extenders, which create a separate network, mesh networks automatically switch your device to the strongest signal without interruption. It’s a better solution for people who move around a lot or need consistent signal strength for things like gaming, video calls, or streaming.
Mesh WiFi systems also make it easier to understand how to boost the WiFi signal in hard-to-reach rooms without needing to run long cables or set up complex networks.
Old firmware can slow down your router and make it vulnerable to security threats. Most routers don’t automatically update their firmware, so you’ll need to log into your router’s settings and check for updates manually.
Firmware updates improve performance, fix bugs, and sometimes unlock features that can help you manage your wireless signal better. If your WiFi signal has been unstable or slower than usual, outdated firmware could be part of the problem.
Some newer Wi-Fi 6 or Wi-Fi 6E routers offer auto-updating features, but it’s still worth checking to ensure your device is running the latest version.
Wi-Fi 6 and Wi-Fi 6E offer faster speeds, better performance in crowded networks, and improved efficiency when multiple devices are connected.
If your current router is a few years old, it might not be capable of handling today’s demands, especially with the rise in smart devices and video conferencing.
Wi-Fi 6 routers can manage more simultaneous connections without slowing down the internet speed. They also help reduce latency—crucial for gaming or large video calls—and improve battery life on connected devices.
Switching to a Wi-Fi 6E router gives you access to even more bandwidth and less crowded channels, which can seriously boost the WiFi signal across your entire home or business.
WiFi is convenient, but it’s not always the most stable option—especially for devices that don’t need to move, like gaming consoles, printers, or desktop computers.
Connecting those directly to the router using Ethernet cables takes some of the load off your wireless network and delivers the fastest internet speeds possible.
Using an Ethernet cable also guarantees that interference won’t slow things down, which is useful in areas where your wireless signal is weak or interrupted by thick walls or electrical devices.
When fewer devices rely on WiFi, the overall performance improves, and you can boost WiFi signal strength for mobile devices that need it most.
WiFi signals operate on channels, and if you’re using the same channel as every nearby network, you’ll run into interference—especially in apartment buildings or office complexes.
Many routers default to the same channel, so switching to a less crowded one can improve signal strength and speed. You can use a WiFi analyser tool to see which channels are congested and pick a better one through your router’s admin settings.
This small tweak helps avoid overlapping signals that affect the speed and reliability of your wireless network.
Most routers come with standard antennas that offer basic coverage, but they aren’t designed to deliver a strong signal across large spaces.
A high-gain antenna can significantly increase the range and direction of your router’s signal.
Instead of spreading the signal equally in all directions, a directional antenna focuses the wireless signal toward where you actually need it—helpful if you’re trying to understand how to boost the WiFi signal in a specific area, like a home office or a gaming room.
A Wi-Fi extender (also called a range extender or signal extender) rebroadcasts the existing signal from your router to areas with weak WiFi. It’s one of the easiest ways to increase the range without upgrading your whole setup.
If your WiFi signal is weak in certain parts of your home or office, placing an extender halfway between your router and that dead zone can dramatically improve performance.
Not all interference comes from walls. Wireless signals can be disrupted by devices like microwaves, cordless phones, Bluetooth speakers, and even baby monitors.
If any of these are placed near your router, they can interfere with the signal and weaken your wireless network.
To boost the WiFi signal strength, move these devices at least a few feet away from the router. Also, avoid placing the router near large metal surfaces, which can block the signal completely.
Keeping the router in a clean, open space—not buried behind a cabinet or near a tangle of cables—can help improve your internet connection instantly.
Before making big changes, it’s smart to understand exactly where the problems are.
Running a speed test near the router and then again in other parts of the building helps you identify which rooms suffer from weak WiFi or slow internet speeds.
There are free apps and tools that can measure both internet speed and signal strength throughout your space.
Not sure if your business Wi-Fi signal is actually holding you back? These signs make it clear when your connection isn’t cutting it—and what to do about it.
One of the easiest ways to tell if your WiFi signal is weak is to run a speed test and compare the results to what your internet provider promises.
If you're paying for fast internet but constantly getting slow speeds, especially during video calls or while using WiFi to connect across different devices, there’s likely a problem with your wireless network or router placement.
Businesses with a single router setup often see a drop in internet speed the farther devices are from the router. This means your Wi-Fi coverage isn’t consistent.
Weak WiFi in certain areas or rooms is a sign that your router’s signal is either being blocked or stretched beyond its range.
Adding a mesh WiFi system or signal extenders can increase the range and stabilise performance across every room.
When devices like laptops or smartphones keep disconnecting or buffering during tasks, it's often due to weak signal strength or signal being interrupted. This can happen even if the WiFi signal shows full bars—because the signal quality, not just the strength, affects performance.
Interference from baby monitors, thick walls, or even using the same channel as nearby networks can block the signal or slow down your wireless connection.
Gaming, streaming, and file syncing should not freeze or drop out if you have a stable network.
If multiple users experience lag in different parts of the building, a mesh Wi-Fi system or Wifi extenders can fix that by knowing how to boost the WiFi signal to areas with bad signal strength.
If devices that are connected directly to the router via an Ethernet cable are still showing slow internet speed, the issue might not be your WiFi signal at all—it could be your router, outdated firmware, or the modem.
Businesses often overlook the impact that old firmware or a low-quality router can have on the entire wireless network.
Upgrading to a Wi-Fi 6 router or even Wi-Fi 6E can help improve performance not only on WiFi but also across the full internet connection.
These newer standards are designed to reduce interference and improve how the signal travels through a building. If performance issues continue on both wireless and wired connections, a router upgrade or a network overhaul may be needed.
WiFi performance is too important to leave to guesswork. Businesses need more than a decent router—they need a network that supports their growth.

Book a consultation today and see how we can extend your signal, improve your WiFi speed, and deliver better internet across every room.
To boost the WiFi signal quickly, start by placing your router in a central location with minimal interference.
Avoid hiding it behind thick walls or large furniture. Upgrading to a Wi-Fi 6 router or using a mesh Wi-Fi system can significantly improve coverage and help boost your WiFi signal in every room.
You can also try a range extender or antenna to increase your signal strength. These are simple steps for making your connection faster and more reliable.
A weak Wi-Fi signal issue can be caused by where your router is placed, interference from devices like baby monitors, or using a single router in a large area.
Slow internet speed might not be caused by your provider—it could be due to poor Wi-Fi performance inside your home.
Running a speed test near and away from your router can help you determine if your wireless signal is strong where you need it.
If you need to extend your signal, using a Wi-Fi extender or mesh system is a good place to start. A booster or signal extender can help eliminate dead zones and increase the Wi-Fi range.
The best Wi-Fi extender will match the speed of your existing setup and ensure the Wi-Fi signal travels without losing strength.
Yes, using an Ethernet cable to connect devices like a laptop or gaming console can significantly improve performance and free up bandwidth for other devices on your wireless network.
Wired connections are faster, more stable, and not affected by interference the way wireless signals are. This is one of the 10 tips experts recommend to fix bad signal strength issues.
If your Wi-Fi connection keeps dropping, or if you're experiencing slow internet, upgrading to a Wi-Fi 6 router or even Wi-Fi 6e is worth it.
These newer routers offer better Wi-Fi coverage, handle more devices, and are built for the demands of gaming, video calls, and smart homes. You should also check your router’s firmware to see if it's outdated.
A mesh WiFi system works differently than an extender by creating a single seamless Wi-Fi network across all nodes. Mesh is great for large spaces, multi-story buildings, or areas with lots of obstacles that can block the signal.
While Wi-Fi extenders work well in small areas, a mesh network gives you consistent Wi-Fi speed and eliminates the hassle of switching networks as you move around your home.
To reduce the chance of your signal being interrupted, keep the router away from your router's known interference zones, like microwaves or cordless phones. Also, switch to a less crowded WiFi channel if you're using the same channel as neighbours.
Using mesh Wi-Fi, placing your router close to your router's most-used areas, and running cable where possible are smart ways to make a big difference in your home Wi-Fi.
