A slow internet connection is one of those problems that seems to strike at the worst possible moment.
Nine times out of 10, it happens right in the middle of a video call or just as your favourite show starts buffering. Before blaming your broadband provider entirely, you should know that your router itself could be playing a bigger role than you’d think. There’s even a viral tip doing the rounds suggesting tin foil can boost your signal, which actually tends to make things worse rather than better. Here’s what helps, straight from the experts who test routers for a living.
Start by checking whether your speed actually matches what you’re paying for.
Before assuming your router is the problem, run a quick speed test to see exactly what you’re currently getting. For an accurate result, connect your laptop or computer directly to the router using an ethernet cable, rather than relying on Wi-Fi for the test itself.
If your results come back noticeably lower than what your provider promised, contact them directly and asking them to help sort it out. No matter how good your router is, your overall speed will always be capped by whatever contract you’ve signed up to.
Work out what speed you actually need.
Speed is measured in megabits per second, and how much you actually need depends entirely on what you’re doing online. Around five megabits per second covers basic browsing and emails, while sixteen megabits per second is enough to stream HD content reliably on a single device.
Sixty megabits per second comfortably handles streaming across a couple of devices along with online gaming and a handful of smart devices around the house. Anything above a hundred megabits per second is ideal if you’re streaming 4K content across multiple devices, while also running plenty of smart tech throughout your home.
Place your router in an area that suits better connection.
Devices connecting over Wi-Fi tend to run noticeably slower the further they sit from your router, so its physical location plays a big role in overall performance. If your router sits in the living room, but you work from an upstairs office, the distance and everything in between could easily be too much for the signal to properly reach.
Walls, furniture, ceilings, and materials like concrete, metal and plaster can all weaken your signal considerably. Everyday appliances like microwaves and cordless phones can interfere too, and tucking your router away in a tight hallway or staircase tends to give noticeably weaker coverage compared to placing it somewhere more open.
Too many devices can slow everything down.
Every phone, laptop, smart speaker and app controlled gadget connected to your Wi-Fi is competing for the same bandwidth, and the more devices you have, the more strain your router faces. Think honestly about which connected devices you actually use regularly, and how many are streaming at the same time throughout the day.
One simple fix is switching your phone over to mobile data instead of Wi-Fi when you don’t specifically need it, freeing up bandwidth for everything else in your home. If you regularly have leftover mobile data each month anyway, this is an easy way to ease the pressure on your router while making better use of what you’re already paying for.
An outdated router could be holding your whole home back.
If you’re still using the exact router your provider sent out years ago, you should probably consider an upgrade. Older routers, particularly ones only supporting outdated wireless standards, can noticeably limit your speed regardless of how good your actual broadband package is.
Third-party routers can often considerably outperform the standard one supplied by your provider, too. If you’re shopping around, you should compare models properly, rather than simply assuming your provider’s router is automatically your best option.
Understanding dual-band and tri-band routers is important.
Basic single band routers only operate on one frequency, which works fine for simple browsing but tends to struggle with gaming or streaming 4K video. Dual-band routers add a second, faster frequency better suited to more demanding tasks, though it doesn’t reach quite as far throughout your home.
Increasingly, newer routers come with a third band as well, splitting devices across multiple frequencies far more efficiently. If your household has a lot of connected devices, this kind of router tends to deliver noticeably smoother overall performance throughout the day.
There are some handy features worth looking for when upgrading.
Some newer routers include gigabit ethernet ports, which are particularly useful for online gaming, since they let your router send and receive data from servers considerably faster. Just remember that you’re still ultimately limited by whatever speed your broadband package actually provides.
Many routers also come with a companion app, letting you manage parental controls, block specific websites, or check exactly which devices are currently connected. This can be a useful tool for spotting exactly what’s eating up your bandwidth at any given moment.
Newer Wi-Fi standards can make a real difference.
Wi-Fi 6 has become the most common standard for newer routers, specifically designed to handle heavy usage and multiple devices connecting simultaneously without everything slowing to a crawl. For busy households with plenty of connected tech, this makes a noticeable difference to everyday performance.
Even newer standards like Wi-Fi 6E and Wi-Fi 7 are gradually becoming more common, too, offering additional frequency bands specifically aimed at improving performance in particularly tech-heavy homes. If you’re upgrading anyway, check which standard a new router actually supports.
It may be time to consider an extender or mesh system.
If you’ve tried everything else and still have patchy coverage, particularly in a large home or awkward layout, a Wi-Fi extender or mesh system could actually help. Extenders are the cheaper option, rebroadcasting your router’s signal into areas where coverage is currently weak or missing entirely, though speed can sometimes drop slightly through this rebroadcast.
Mesh systems work a bit differently, using multiple matching devices positioned around your home to extend your router’s signal seamlessly rather than creating a separate network. A well-positioned mesh setup can extend solid coverage right out into a garden, driveway, or garage. Before buying either option, check whether your provider offers one for free as a straightforward fix for weak coverage.
