Avoid placing the router on the floor, especially if you need Wi-Fi signals on a second floor.

When positioning your router, consider avoiding the baby’s room or kitchen, as appliances such as microwaves and baby monitors emit wireless frequencies that can interfere with your Wi-Fi signals.


Selecting the Right Wi-Fi Frequency

Your home’s WiFi devices typically use two frequency bands: 2.4 GHz and 5 GHz. The main difference between the two is that 2.4 GHz offers better range and penetration of physical objects, but it has slower speed capabilities compared to 5 GHz.

If you’re looking for optimal performance, consider using Dual-Band WiFi technology, which allows devices to switch between the two frequency bands depending on which one works best. 

However, the 2.4 GHz band can be affected by interference from other wireless devices such as baby monitors, microwave ovens, and Bluetooth gadgets, which can negatively impact performance.

The 5 GHz band, on the other hand, is less susceptible to interference, but older routers may not support it.

If you have a Wi-Fi 5 or 6 router, it will support the 5 GHz band, but older 802.11n routers may not.

You can check your router specifications in the box, manual, or your WiFi networks if you can see an “SSID”_5G at your home.

To improve your WiFi performance, you can switch between the 2.4 GHz and 5 GHz bands depending on your distance from the router.

When you’re closer to the router, connect to the 5 GHz frequency to get faster speeds. If you’re farther away, switch to the 2.4 GHz frequency for more stable WiFi performance.

Rebooting or updating your router

If you’re experiencing issues like weaker wireless signals and slower internet speeds with your Wi-Fi router, there are a few steps you can take to fix these problems. 

One common solution is to update your router’s firmware. 

To do this, you’ll need to first download the latest firmware for your specific router model. 

You can find this by searching for “download *insert router brand name* firmware” on your preferred search engine. 

Once you’ve found the firmware, log in to your router by entering the URL address found on the back of your router into your PC’s browser. From there, find the firmware update section in the menu and click on the update button. 

If you encounter any errors during the automatic update, you can download the firmware file manually. 

If you need to perform a hard reboot or factory reset, make sure to take note of all your ISP’s data and settings beforehand.

Create a Mesh Network

If you’re looking to boost your Wi-Fi signal throughout your home, mesh systems are a great solution.

By placing wireless access points in various locations, you can ensure reliable and strong coverage in every room.

This is particularly beneficial for large homes or duplexes with smart gadgets since seamless roaming ensures that your devices stay connected as you move around.

When selecting a mesh system, consider the number of streaming devices you have at home. Dual-band or tri-band routers can be suitable depending on your needs and budget.

Based on years of testing experience, the Netgear Orbi is the best mesh WiFi system available. However, if you’re on a budget, the TP-Link Deco offers a cost-effective option.

It’s important to note that while wireless mesh networks are convenient, they may not be optimal for competitive gaming and high-quality streaming. In such cases, connecting the nodes with Ethernet cables is the best way to maximize performance.

Use a WiFi Extender

If you’re facing weak signals in certain areas of your home, expanding your WiFi coverage without replacing or upgrading the entire setup can be done using a Wi-Fi repeater. 

A WiFi extender is particularly useful in addressing connectivity issues in specific areas like your front yard, backyard, patio, or garden. This solution eliminates the need to run ethernet cables across. 

To get started, simply locate a power outlet closer to the dead zone, determine the optimal signal strength, and configure your signal repeater. 

There are many big market players offering a wide range of devices, such as Netgear and TP-Link, so you can find the perfect fit for your needs.

Connect to a WiFi access point

If you’re worried about losing internet speeds or experiencing slow uploads due to wireless communication, you may want to consider using a WiFi access point instead of repeaters.

An access point connects to your network via a wired connection and transmits wireless signals for other devices to access the internet. 

This can be particularly useful if you have a large area outside your home covered by security cameras and require a weatherproof access point designed for such purposes.

However, before selecting an access point, make sure you have the ability to run ethernet cables within your home.

Access points are typically used in corporate offices and commercial buildings to cover extensive surface areas with internet coverage. 

For residential use, the current generation of WiFi extenders includes portable devices that function as both WiFi repeaters and access points, complete with additional ethernet ports.


Invest in a Powerline Adapter

If you’re looking for a solution that doesn’t involve running cables throughout your entire house, powerline adapters can be a great option.

These adapters use your home’s electrical wiring to extend the range of your Wi-Fi connection. You can install multiple adapters throughout your home, as long as your electrical wiring is adequate. 

By installing several high-quality powerline adapters in various rooms, including one near the router, you can use your electrical wiring to transmit the internet signal and access high-speed internet, resulting in better WiFi coverage. 

This technique avoids the speed loss that occurs with WiFi transmission.’

If you want to use them to increase your Wi-Fi range, you’ll also need to purchase another router. 

Be sure to get the correct type of adapter for your needs. Some adapters, like the one we recommended earlier, include Wi-Fi functionality. Do your research before making a purchase.

Make use of a MoCA adapter

If you’re struggling with slow Wi-Fi speeds due to thick concrete walls in your home, there are various ways to improve your signal.

One option is to use MoCA adapters, which utilize existing coaxial cables in your home to boost your Wi-Fi connection.

This method is comparable to powerline adapters, but MoCA adapters are generally quicker and can reach speeds of up to 1Gbps.

To extend your internet speeds to every room in your home, you can also utilize additional MoCA adapters.

However, it’s essential to remember that not every house has coaxial cable connections in every room, so you’ll need to examine your home’s wiring before deciding on this option.

It’s also crucial to guarantee that your MoCA adapter has a Wi-Fi connection, similar to powerline adapters, for optimum performance.

Keep in mind that while MoCA adapters can be a valuable solution for boosting your Wi-Fi signal, they may not be the best option for every home.
