Is Your Wi-Fi Slow — Or Is Someone Else Using It?

I grew up with dial-up internet. If you know, you know — the screeching sound of the modem connecting, the agonising wait for a single image to load from top to bottom, the absolute devastation of someone picking up the phone and killing your connection mid-download. I lived through all of that, and I have zero nostalgia for it. Which is exactly why slow internet in 2026 makes me unreasonably irritable. We have come too far for this.

So when my connection started crawling recently, I did what most of us do — I mentally drafted a strongly worded message to my internet provider. But before I sent it, I did a little investigating. And what I found was that the problem was not my provider at all. It was my own network, quietly overwhelmed and, frankly, a little too generous with access.

If your Wi-Fi has been sluggish, here is what might actually be going on — and what you can do about it.

More Devices Than You Realise Are Sharing Your Connection

Every device connected to your Wi-Fi is taking a slice of your bandwidth. Your phone, your laptop, the smart TV in the living room, the tablet the kids use, the wireless speaker you forgot was connected, the smart bulbs someone convinced you to buy. It adds up quickly. And the more devices sharing the connection, the slower it gets for everyone.

You can actually see everything connected to your network by logging into your router. Most routers have a companion app, or you can type an address directly into your browser — usually something like 192.168.1.1 or 192.168.0.1. From there you will find a list of every connected device. If something appears on that list that you do not recognise, that is worth your attention.

Change Your Wi-Fi Password — And Enjoy the Power

Here is something I discovered that I genuinely enjoy. When you change your Wi-Fi password, it disconnects everyone. No favourites, no exceptions. Every single device gets kicked off the network simultaneously, and you get to decide what comes back on, and when.

This is an underrated parenting tool. If the children are supposed to be studying and you suspect streaming is happening instead, a password change is swift, silent, and devastatingly effective. It is also the polite but firm solution for the neighbour you gave your password to once — out of hospitality — who never quite stopped using it. You offered a cup of water; they moved in. A new password fixes that.

There Are Actually Two Passwords on Your Router

Most people know their Wi-Fi password — the one you type in when connecting a new device. Far fewer people know that their router has a second, separate password that protects the device itself and all its settings. This is your router admin password, and it is arguably more important than your Wi-Fi password.

If someone gains access to your router settings, they can change your Wi-Fi password, monitor everything passing through your network, or lock you out of your own connection entirely. Most routers ship with a default admin password — something embarrassingly simple like "admin" or "password" — and those defaults are widely known. Log into your router and change it.

I will be transparent with you here. I have changed my router admin password, promptly forgotten it, and locked myself out. It was not my finest moment. So when I tell you to change it, I am also telling you from hard experience — write it down somewhere safe the moment you change it. A note in your phone, a piece of paper in a drawer, a password manager. Somewhere. Do not rely on memory.

Where You Put Your Router Matters More Than You Think

Here in Jamaica, we build solidly. Concrete block and steel are the standard, and our buildings are sturdy and strong. That is wonderful for withstanding storms. It is considerably less wonderful for Wi-Fi signals, which do not pass through dense concrete and steel the way they do through timber-framed walls.

This is why router placement is not a trivial thing. A router sitting on the floor in a corner, tucked inside a cabinet, or pushed against an exterior wall is fighting against the very structure of your home. Mount it high, position it as centrally as possible, and keep it out in the open. Think of the signal radiating outward in all directions — you want as few walls and obstacles as possible between the router and the rooms where you actually use the internet.

If you consistently get poor signal in certain rooms despite good placement, a Wi-Fi extender or a mesh network system can fill in the gaps without requiring you to upgrade your internet plan.

Restart Your Router — Regularly

This sounds too simple to be real advice, but it works. Routers accumulate connections, clear temporary memory issues, and generally perform better after a restart. Once a week is not excessive. If you have not restarted yours in months, do it today and notice the difference.

A Quick Checklist Before You Call Your Provider

• Log into your router and check what devices are connected

• Change your Wi-Fi password if it has not been changed recently — or ever

• Change your router admin password if it is still set to the factory default, and record it somewhere safe

• Move your router to a higher, more central position if possible

• Restart your router

A Note for the More Adventurous

If you are comfortable poking around in your router settings beyond the basics, there are two more things worth doing. First, check whether your router firmware is up to date. Firmware is the software that runs your router, and manufacturers release updates periodically to fix security vulnerabilities and improve performance. Most modern routers have a firmware update option sitting right inside the admin settings — it is worth checking and running updates regularly. Think of it the same way you think about updating your phone. Outdated software is an open door.

Second, consider setting up a guest network. Most modern routers support this, and it is one of the smarter things you can do for your home network. A guest network runs separately from your main network, which means visitors, the neighbour you occasionally trust, and yes — smart home devices like bulbs and speakers — can connect to the internet without having any access to your main network and the devices on it. It compartmentalises your traffic and keeps your primary devices cleaner and more secure. Your laptop and your smart TV do not need to be on the same network. Separating them is a small step with a meaningful security payoff.

Slow internet is frustrating. But a surprising number of speed and security problems are fixable at home, without a service call, without a technician, and without spending any money. Start with these steps before you reach for the phone to call your provider. You might be pleasantly surprised.
