Is Your Smart Doorbell Slowing Down Your Wi-Fi? (And Is It Safe?)
From smart lights and thermostats to video doorbells and security cameras, homes in Wickford and Basildon have more gadgets than they did a few years ago, and the router is being asked to look after all of them.
A handy gadget can add traffic your Wi-Fi wasn't set up for, and a poorly secured one can weaken your home network. At LaunchLayer, we help local families check over their smart home so it stays quick and sensibly secured.
1. Why Your Smart Home Might Be Slowing You Down
Every smart device uses a little of your connection. Even when it looks idle, it sends short updates back to the company that made it.
A camera takes a steady slice of upload. A security camera uploads video constantly, and several cameras running at once can make video calls laggy and films buffer.
The 2.4GHz band is already busy. Many older or budget smart devices only use the 2.4GHz frequency. That band is shared with baby monitors, microwaves and neighbours' Wi-Fi, so interference is common.
2. The "Digital Backdoor": Is Your Kettle a Security Risk?
A common weak spot is a smart plug or cheap camera that still has its default factory password.
One weak gadget can be a route further in. If someone gets into a smart bulb, they may be able to move across the network towards your laptop, where your banking and personal files are.
Newer UK rules cover what manufacturers must ship. UK rules that came in during 2024 ban easy-to-guess default passwords and require manufacturers to say how long a device will get security updates. A smart device that's several years old may no longer get updates, which is worth knowing when you decide what stays on the network.
3. Three Ways to Secure and Speed Up Your Network
Put the smart gadgets on a guest network. Move smart devices onto the router's Guest Network. Keeping them separate means a problem with a smart bulb is less likely to reach the computers and phones you actually use.
Turn on two-factor authentication where the app offers it. If your smart camera app offers 2FA, turn it on. Then a password on its own isn't enough for someone else to open the live view.
Use a cable for the heavy devices. If the smart TV or games console is near the router, connect it with an Ethernet cable. Taking those devices off the Wi-Fi leaves more room for the wireless gadgets.
