What are Wi-Fi boosters and how do they work?

Introduction to Wi-Fi Boosters

In the age of streaming, gaming, and the ever-growing number of connected devices in our homes, a strong and reliable Wi-Fi connection is more important than ever. Wi-Fi boosters are the unsung heroes in the quest for uninterrupted internet connectivity. These handy devices are especially useful in homes with thick walls, multiple floors, or distant rooms where the Wi-Fi signal from the main router struggles to reach.

How Wi-Fi boosters work

Wi-Fi boosters are like digital bridges that extend the reach of your internet connection. They capture the signal from your router and rebroadcast it to other parts of your house that were previously Wi-Fi dead zones.

There are a few types of boosters, including powerline adapters, which use your home's electrical circuitry to transmit data, requiring two power adapters and an Ethernet cable. Alternatively, repeaters and mesh Wi-Fi systems act as secondary routers, picking up the Wi-Fi signal and spreading it further.

Functionality of Wi-Fi boosters

The primary function of Wi-Fi boosters is to ensure that every corner of your home has access to a stable internet connection. Whether you're trying to stream a movie in the attic or work from your garden shed, a Wi-Fi booster can help maintain a strong signal so you can enjoy a seamless online experience.

Wi-Fi extenders vs. boosters

While the terms extenders, repeaters, and boosters are often used interchangeably, they all serve the same purpose: to improve your internet connectivity in areas with poor coverage. Depending on your needs and budget, you might opt for:

• Powerline adapters that use your home's electrical wiring

• Repeaters that function as secondary routers

• Mesh Wi-Fi systems for a more comprehensive and seamless coverage, though these are a more expensive option

Wi-Fi booster providers

Many broadband providers offer their own Wi-Fi booster solutions, often for an additional monthly fee. However, you're not limited to these options; you can also purchase third-party devices to extend your network. Here's what some of the providers offer:

• Sky offers a Broadband Boost service for £5 a month that guarantees a solid connection in every room.

• Virgin Media offers Wi-Fi Pods

• BT offers a Complete Wi-Fi deal with a Smart Hub 2 and a Wi-Fi Disc

• Vodafone Pro Broadband customers can get a Super Wi-Fi Plus booster with an Alexa-equipped speaker and 4G backup

• TalkTalk offers a Wi-Fi extender kit that uses powerline technology

Effect on Broadband Speed

Wi-Fi boosters can be a game-changer for broadband speed in areas with a previously weak signal. However, it's worth noting that as you move further from the booster, the connection may weaken, and speeds may decrease. This is a common trade-off with Wi-Fi extenders, as they often prioritize range over speed.

Improving broadband speed

Before you invest in a Wi-Fi booster, consider whether you can enhance your broadband speed by simply upgrading or repositioning your router. An up-to-date router in the right location can significantly improve your connection. If you're not sure how to proceed, read our guide on how to diagnose and improve your internet speed.
