Understanding WiFi and how to improve your home connection
WiFi and internet usage are essential parts of life in today’s digital age. According to Statista, there were 6 billion internet users worldwide as of 2025, which is up from 5.5 billion in 2024. It’s hard to remember a time before the internet, and now roughly 74% of the global population is online, with that number continuing to rise each year.
As our reliance on connected devices grows, understanding how that WiFi and internet connections actually work becomes more important. Whether you’re streaming movies, working from home, or just using your smartphone, WiFi plays a major role in keeping you connected. And yet, many people aren’t sure what WiFi really is and how it differs from their internet service. Learning the basics can make a big difference in knowing how to troubleshoot issues with your connectivity.
How does WiFi work?
WiFi is a wireless technology that connects your devices to the internet without needing a physical cable. Instead of using something like an Ethernet cord, WiFi uses radio waves to transmit data through the air.
Does WiFi automatically come with internet?
Not necessarily. WiFi is not required to access the internet, but it is one of the most common ways to get online wirelessly at home. Devices like smartphones, tablets, and laptops typically use WiFi to connect to the internet.
WiFi is created by a router which connects to your modem, or for fiber connections, your optical network terminal (ONT). Once connected, routers broadcast a signal throughout your home that your devices can join.
Pulse’s Fiber Internet packages include WiFi, so when you sign up for Pulse, you’ll get a router as part of your setup. You can choose to use your own router, or we might provide you with a combined device that includes both a fiber ONT and a router in one unit.
Tips to improve your WiFi connection
There are several simple steps you can take at home to understand your speeds and improve your WiFi performance.
Check out another one of our blog posts here that includes step-by-step instructions on how to diagnose issues with your at home WiFi. Knowing whether you have a connection problem, a router problem, or a coverage problem before adjusting equipment or settings can help determine your next steps.
Move your router for better results
WiFi signals travel best through open spaces. If your router is tucked into a cabinet, closet, or hidden corner, your performance may suffer.
For the best results:
- Place your router in an elevated, open, and central location
- Keep it near the center of your home
- Avoid placing it behind walls or large appliances
A router placed at one end of the home may provide weaker coverage in areas farther away.
Use a WiFi extender
If you have a large home, one router may struggle to cover the entire area. Pulse provides WiFi extenders with our 1 Gig and higher plans to help ensure stronger coverage throughout your home.
Understand the difference between networks
Most routers broadcast two WiFi networks: 2.4 GHz and 5 GHz. These bands serve different purposes and may affect the performance of different devices.
The 2.4 GHz network travels farther but has a slower speed. It is best for connecting smart home devices throughout the home and rooms located farther away.
The 5 GHz network has a faster speed, but a shorter range. It is ideal for streaming, video calls, and gaming when you are close to your router.
Choosing the right network for each device will help you get the strongest and most consistent WiFi performance.
Now that you have a better understanding of WiFi and how it works, you can feel more confident troubleshooting issues on your own, or reaching out to Pulse for support. As your local provider, we’re here to make sure your internet and WiFi perform the way they should.
