By Rob Orr / Last updated: Feb 16, 2023


Ah yes – the dreaded WiFi interference problem. It’s an absolute nightmare when there’s a problem with your wireless signal for everyone working at home these days, and who’s not working at home?

WiFi interference is caused by many things, including cordless phones, microwaves, baby monitors, cordless doorbells, metal in your walls, concrete and brick walls, and even your own devices like laptops, tablets, smartphones, and gaming consoles.

Wireless routers are a blessing because they provide access to your internet service via radio signals all throughout your home office.

But they can also be fickle and buggy if they’re not set up right, or there’s signal interference. Having a strong wireless signal is essential for maximum productivity.

Wifi interference is a common problem that affects millions of people around the world.

If you’re experiencing wifi interference at home, there are several reasons why this might happen. In this article, I’ll explain what causes wifi interference at your home and how to fix it.

How can I reduce wifi interference at home?

If you are having issues with WiFi signal strength or speed, there are some things you can try.

First, make sure that your router is set to the correct channel.

Second, if you have multiple routers, make sure they are all on the same channel.

Third, if you have a wireless repeater, make sure it is set to the correct frequency. Fourth, if you have a range extender, make sure it is connected to the right network. Finally, if none of these work, consider upgrading your router.

What causes WiFi signal interference at home?

So many things can cause interference for your WiFi signal at home.

WiFi wireless routers operate on 2.4 GHz frequency band which means they will interfere with nearby devices using 5GHz spectrum. If you have multiple routers operating on different channels, then chances are high that one router could be causing interference for another device.

If you’re having problems with WiFi in the house or on a business trip, it’s important to know what is causing this problem so that you can take steps to fix it.

How do I find out what is causing my WiFi interference?

The first step is to identify which device or devices are interfering with your wireless network. You’ll need to determine if there is an issue with any of these:

Cordless Phones

If you have a landline phone connected to your router via RJ11 cable, then you may experience issues when using your cell phone near your router. This could cause data loss for both wired and wireless connections.

Microwave Ovens

A microwave oven will interfere with your Wi-Fi signal because they operate on 2.4 GHz frequency band. The best way to avoid this type of interference is to keep your microwave as far away from your router as possible.

Baby Monitors

Many baby monitors use frequencies between 900 MHz and 1.9GHz to transmit audio signals. These types of monitors should not affect your Wi-Fi connection unless you place them directly next to your router.

Door Bells

Believe it or not, door bells also emit radio waves that can disrupt your Wi-Fi signal. To reduce their effect, try placing your router farther than 10 feet away from where you want to install the bell.

Laptop/Tablet Computers

Laptops and other portable computers often generate electromagnetic fields that can interfere with nearby routers. Try moving your laptop closer to another wall or desk instead of sitting right next to your router. Also consider purchasing a separate Ethernet port for your computer.

Gaming Consoles

Some video game systems such as Xbox One and PlayStation 4 utilize high power RF emissions that can create interference with nearby networks. It’s recommended that you turn off all games before connecting to your internet service provider.

What else might be causing my wifi interference?

Other Devices

There are several other household items that can cause interference with your Wi-Fi network. For example, some garage doors openers use frequencies around 915MHz. Cordless telephones operating on 1900MHz can also cause interference.

Power Lines

High voltage electrical lines running through your neighborhood can cause interference with your wireless network. Make sure that none of your neighbors’ homes share the same electric company.

Radio Frequency Emissions

Your home appliances, electronics, and vehicles can produce unwanted RF radiation that can interfere with your wireless network. Turn down your television volume while watching TV, limit how much time you spend playing video games, and make sure that your mobile devices don’t stay too close to your body.

Wireless Networking Equipment

Even though most modern routers come equipped with built-in antennas, they still require external antennae to function properly. Be careful about installing additional equipment in areas where it’s likely to block access points.

What physical materials cause WiFi Interference?

There are many different kinds of material that can cause interference with WiFi signals. Here are just a few examples:

Plastic Shelf Clutter can interfere with your WiFi signal

Plastic shelves placed above your router can act like an antenna by reflecting incoming signals back towards your device. You’ll need to remove any plastic shelving units if you’re having problems accessing your Internet connection.

Metal objects can interfere with your WiFi signal

If there are any kind of metal objects such shelves, or walls near your router, they can block the wireless signals from reaching your laptop. This can cause slow internet speeds, especially when you are using a wireless network. To fix this problem, try moving your router away from these items.

Water pipes can interfere with your WiFi signal

The water pipes running through your house can cause problems too. You may notice that your wireless internet connection drops out intermittently. This is because the water pipe acts like a big antenna, picking up signals from nearby routers and amplifying them.

Electrical wires and wiring can interfere with your WiFi signal

Even the electrical wiring in your home office can cause interference with your wireless signals! That’s why finding a good place to deploy your wireless router or access point is so important.

Concrete, brick, and thick walls can interfere with your WiFi signal

If you have concrete or brick walls in your home, they may block your wireless signals. This means that you won’t be able to connect to your router through your smartphone or laptop. If you’ve got thick/dense brick or concrete walls in your home office it may be a good idea to get a wireless extender.

How do I know if there is an issue with my WiFi Router?

If you’re experiencing poor performance with your current router, here are some things to check first:

Is your router located within line of sight of your modem? If so, move it further back into a corner of your house.

Do you have any metal objects near your router ? Move these out of range of your router.

Are you using a wired ethernet cable when trying to connect to your Internet Service Provider? This may prevent your router from detecting your device.

How many people live at your residence? More users means more traffic over your Wifi network. Consider upgrading to a higher speed plan.

Does anyone else in your family use your router? You should only allow one person per IP address to log onto your router. Otherwise, everyone will experience slow speeds.

Can you get better reception by changing channels? Many routers support up to 11 different frequency bands. Changing between them could improve your connection quality.

Have you tried turning off your router completely and then restarting it? Sometimes this helps resolve issues caused by hardware problems.

How do I fix WiFi Interference?

If you’ve determined that one of the above sources is responsible for disrupting your wireless network, here are some steps you can take to resolve the problem:

Change Location – Move your router so that it isn’t located within 5 meters of any of the offending devices listed above.

If you’re unable to move your router, then at least change its location by using an extension cord. This may help prevent interference caused by things like doorbells and microwaves.

Use Antenna Placement – Place your router near a window if possible. Windows tend to have less RF noise coming into them compared to walls and floors. You could even purchase a small outdoor antenna to improve reception.

Turn Down Volume – Reduce the volume level of your speakers, TVs, radios, etc., when not actively being used. The lower the sound levels, the fewer signals will be emitted which can result in better performance.

Limit Time Spent Playing Video Games & Using Computers – Limit the amount of time spent gaming and working on your computer. These activities typically involve more powerful transmitters and therefore increase the likelihood of creating interference.

Install a Wired Connection – A wired connection provides a reliable alternative to relying solely on wireless technology. In addition, many newer laptops include Ethernet ports making this option easier than ever.

What else I should know?

Yes! Here are a few tips to keep in mind when troubleshooting issues related to your Internet Service Provider :

Make Sure That All Modems Are Connected Properly – Ensure that each modem has been connected correctly and securely. Also check that all cables are firmly attached to their respective modems.

Check To See Whether Any Of Your Modem’s Settings Have Been Changed – Some ISPs allow customers to customize certain settings such as port forwarding or DNS servers. It’s important to ensure these settings haven’t changed since installation.

Reset Your Router’s Default Password – Many ISP providers offer instructions online regarding resetting default passwords. However, doing so requires accessing the device via a web browser. Resetting the password manually allows you to bypass this step.

Contact Customer Support For Help With Troubleshooting Issues – Most internet service providers provide customer support services through phone calls, email, chat, or live assistance. Contact your provider directly to determine whether they offer technical support options.

What Is Wi-Fi And How Does It Work?

Wi-Fi is a type of networking standard developed by IEEE. It enables users to connect wirelessly with other computers, printers, smartphones, tablets, smart watches, security cameras, thermostats, garage doors, baby monitors, and much more.

Wi-Fi works over radio waves just like traditional cellular networks do. But unlike cell phones, routers use antennas instead of towers to send out data.

How Do Routers Communicate Data Over Radio Waves?

Routers communicate with each other using radio frequencies called channels. Each channel corresponds to one specific frequency range within an area known as a “bandwidth.” This bandwidth determines how fast information can travel between two devices.

The higher the number of available channels, the faster the speed at which data travels. Channels also vary based on location. So, for example, most people living in urban areas experience slower speeds because there may only be three or four usable channels in those locations.

Rural residents often have access to hundreds of channels.

Is There A Way To Reduce Home Wifi Interference At Night?

Yes! If you want to keep your home from interfering with neighbors’ signals during nighttime hours, here are some tips:

Put up a metal shield between your router and your neighbor – You’ll need to purchase a special shielding kit designed specifically for this purpose. The kits usually come with screws, nuts, bolts, washers, and spacers. Simply place them around your router and tighten down any loose items until everything fits snugly together.

Use a mesh system – Mesh systems consist of several small boxes placed throughout your house. They’re meant to create a barrier against outside noise while allowing strong signals to pass through. These types of systems typically cost less than $100.

Use An Ethernet Cable Instead Of Wireless Networking Devices – When possible, opt for wired connections whenever possible. Wired connections will not interfere with neighboring homes when used properly.

Install Antennas On The Outside Walls Or Ceiling – Installing external antennae outside walls or ceilings helps improve reception. You should place them about six feet away from any obstructions and point them towards the direction where you expect the strongest signal.

Turn Off All Unnecessary Electronics In Other Rooms – Turn off electronics in rooms adjacent to your main room. These include TVs, stereos, microwaves, etc.

How To Boost Your Home’s Wifi

If you want to improve your internet connection speed and quality, here are some tips that will help you:

1. Make sure your router is connected to a high-speed broadband modem.

If you have a wireless router, make sure it is connected to a high speed broadband modem. This will ensure that your internet connection is fast enough to stream HD videos or play online games.

2. Use a wired Ethernet cable instead of wireless.

Wired connections provide better performance than their wireless counterparts. They allow users to transfer large amounts of information quickly without sacrificing bandwidth.

3. Install an external Wi-Fi booster.

External boosters increase the amount of coverage area around your house. This means that even though your current router has weak spots, you’ll still get good service throughout your entire property.

4. Use High Gain Amplifiers.

HGAs boost weak signals so that they become strong enough to reach their destination. They usually come in pairs; one amplifies incoming signals while another degrades outgoing ones.

5. Install External Antenna.

External antennas help increase the amount of space between your device and its source.

6. Connect Multiple Access Points Together Using Repeaters.

A repeater is used to connect multiple access points together using radio frequency signals. The repeater receives a signal from one access point and retransmits it to all other access points connected to it. This allows for more wireless devices to be connected to a single access point.

What is the best WiFi router I can buy?

The best way to ensure that your home network has a strong signal is to use a high-quality router. A router is like a telephone pole for your internet connection. The higher the quality of the pole, the stronger the signal.

The best WiFi routers on the market today offer many features such as dual band support, MU MIMO technology, beamforming capabilities, smart scheduling algorithms, QoS, and much more. Some models also feature advanced security options like AES 256 encryption, VPN tunneling, MAC address filtering, parental controls, guest network creation, and others.

The most important thing to consider when buying a new WiFi router is how well it supports 802.11ac. Most modern smartphones use this standard which makes it easy to find compatible products. If you’re looking for something simple, then look no further than TP Link Archer C7 AC1200 Dual Band Gigabit Router. It offers great speeds at affordable prices.

If you want an extra layer of protection against hackers or malware attacks, then check out Netgear Orbi Outdoor Wi-Fi System. It includes four outdoor units plus one indoor unit. All of them work seamlessly together to provide fast and reliable connections.

Netgear Orbi uses mesh networking technology to create a secure environment where each node works independently without relying on central servers. In addition, it provides 24/7 monitoring services via the cloud.
