Every so often a story about smart television security ripples through the news, everyone forwards it to the group chat, and then nothing changes. The set stays online, the voice assistant stays switched on, and the router password stays whatever the installer typed in years ago. I understand why. Digital housekeeping has none of the satisfaction of a folded linen cupboard. But there is a version of it that takes one evening, costs nothing, and leaves you with the same feeling as a cleared kitchen counter: fewer things running in the background, less noise you didn't consent to.
Start with a list, not with settings menus
Before you touch a single device, do a walk-through with a notebook. Write down everything in your home that connects to the internet: television, streaming stick, speakers, doorbell, robot vacuum, printer, that old tablet propped in the kitchen, the fitness scale, the games console the children use. Most people are surprised by the length of the list. Then, next to each item, write one word: why. Why does this need to be online?
Some answers are obvious. Your streaming stick needs the internet because streaming is its entire purpose. Others are less convincing. A printer that only ever prints from a laptop in the same room does not necessarily need to sit on your network permanently. A television used exclusively as a screen for a separate streaming device does not need its own connection at all. This is the whole audit in one question, and it does more for you than any advanced setting.
The television is worth ten minutes on its own
Modern sets are not just screens; they are computers with an advertising business attached. Two things are worth finding in the menus. The first is any setting related to viewing information, content recognition or personalised recommendations, often buried under privacy, terms or additional agreements rather than picture settings. Turning it off will not break your television. The second is the microphone, if the set has one for voice search. If you have never once spoken to your television, switch it off and see whether you miss it.
While you are in there, run the software update manually rather than waiting for it to happen. Manufacturers issue fixes for exactly the kind of flaws that make headlines, but only if the set is switched on and given the chance to install them. If your television is genuinely old and no longer receives updates, the honest option is to unplug it from the network and run everything through a cheap streaming stick you can replace when it ages out. It costs less than a takeaway and it moves the risky, connected part of the system into a device you actually control.
Fix the router once, benefit for years
Your router is the front door, and most of us have never changed the lock. Log in to it — the details are usually printed on the underside — and do three things. Change the administrator password if it is still the default. Change the Wi-Fi password if it has been shared with a decade of houseguests, plumbers and teenagers. And, if your router offers a guest network, switch it on and put the chattier gadgets on it: the vacuum, the doorbell, the smart plugs. Guests get their own line too, and your laptop with your work files stops sharing a network with a bargain-bin smart bulb.
Then write the new passwords somewhere sensible. A password manager is ideal; a note in a locked drawer is better than a memory that will fail you at the worst moment.
Do the boring maintenance while you're there
Delete the apps you no longer use from the television and the tablet, because every unused app is another account, another login and another thing that never gets updated. Sign out of streaming services on devices you have given away or sold. Check which family members are still on shared accounts. If you have a smart speaker, look at whether recordings are being kept and clear the history. None of this is dramatic. It is the digital equivalent of returning the borrowed dishes and throwing out the expired spices, and it produces the same lightness.
Does unplugging the TV from the internet actually help?
It genuinely does, in a simple mechanical way: a device that is not on your network cannot be reached across your network, and it cannot send anything home either. The trade-off is that you lose the built-in apps, which is why pairing an offline set with a small, cheap, regularly updated streaming device is such a tidy solution. If you rely on the television's own apps and do not want to change that, keep it connected but keep it updated, and turn off the tracking settings.
How often should I redo this audit?
Twice a year is plenty for most households, and the easiest way to remember is to attach it to something you already do seasonally — the clock change, or the weekend you swap the wardrobe over. New devices arrive at birthdays and Christmas, so a January pass catches them. The list you wrote the first time makes every repeat visit take twenty minutes rather than an evening, which is exactly the point: the hard part is only hard once.
