Nine times out of ten, the Wi-Fi complaint we walk into in Dundee is not really a router problem. The router is fine. It's just been put in the worst place in the house — usually because that's the corner of the building where the phone line came in, or where a previous tenant left the cable, or where somebody didn't want to see it. Move the same router two rooms over and the same house suddenly has proper coverage.
That's the pattern that shows up on nearly every Wi-Fi callout, whether it's a West End tenement flat near the university, a Broughty Ferry villa, or a 1970s semi up near Downfield. This guide walks through why placement matters more than the model, the five worst spots we still find routers in, where a router actually wants to live, and when even perfect placement won't save you.
Why the Model Matters Less Than Where It Sits
Wi-Fi is radio. Radio signal weakens as it travels through matter, and it weakens a lot faster through some materials than others. Plasterboard and internal wooden doors are almost invisible to a 2.4 GHz signal — a modern router will punch through several of them without noticing. Solid masonry, thick sandstone, concrete, brick chimneys, cast-iron plumbing, and metal-lined kitchen units are a completely different story. Two brick walls in a Dundee tenement will absorb more signal than a whole hallway of stud partitions in a new-build.
The 5 GHz band that modern routers push most devices onto is faster but travels a shorter distance and is worse at penetrating walls than 2.4 GHz. That means the further your device sits from the router, the more the router quietly downgrades you to slower connections just to keep you online. By the time you're two rooms and one masonry wall away, you're on the slow band at a fraction of the speed the router is actually capable of.
Buying a bigger router doesn't fix any of that. It might raise the ceiling of what's possible, but the walls between the router and your devices are still the same walls. The physics doesn't care what's printed on the box.
Five Router Spots We Keep Finding on Dundee Callouts
These are the recurring five. When we walk in and see any of them, we can usually predict which rooms will have trouble before the customer tells us.
Inside a kitchen cupboard. Kitchens are full of metal — the oven, the microwave, the fridge, sometimes cast-iron pipework in older Dundee properties. A router shut inside a cupboard next to any of that is broadcasting into a metal box. Even if it works, the signal that reaches the rest of the house is a shadow of what the router is capable of.
On the floor behind the TV unit. Signal spreads outward and slightly upward from the antennae — putting the router at ankle height means the ground floor gets a decent signal and the bedroom above gets very little. The TV, sound bar, and games console also add to the interference immediately in front of it.
In a hallway press or under the stairs. A very common Broughty Ferry and West End Dundee find. The phone line comes in there, so the router lives there — surrounded by a plaster ceiling above, masonry walls either side, and coats. Every direction the signal wants to go is blocked.
Right next to a smart TV or a set-top box. Modern smart TVs and streaming boxes are strong sources of electrical noise on the 2.4 GHz band. A router sitting on top of one is fighting its own household for airtime.
Up on a top shelf against an outside wall. High up is genuinely better than low down, but pressed against a thick outside wall means half the signal is being wasted heating up the wall and leaking out into the street. Ideally the router radiates into the house, not out of it.
Where Your Router Actually Wants to Live
The rule of thumb is boringly simple: as central to the living space as possible, at about waist or chest height, out in the open, and away from other electronics. A router on a shelf in an internal hallway roughly in the middle of the flat, with clear line of sight into the main rooms, will outperform a much fancier router shut in a cupboard on the outside wall.
In a Dundee tenement with the incoming line in an awkward corner, the fix is usually a long Ethernet cable to relocate the router itself — not another mesh node, not a signal booster, just moving the router to a better spot. On a recent Broughty Ferry job the customer had bought a top-tier mesh system to solve dead spots, and the real fix was a fifteen-metre flat Ethernet cable tucked under skirting so the main router could sit in the hallway instead of the granite-walled utility cupboard it had been installed in. The mesh nodes came out of the box and stayed there.
Where a long cable isn't possible — a rented flat where you can't drill, or a Perth or St Andrews stone-walled cottage where the walls are too thick to trench — that's when a mesh system or a wired access point earns its keep. But it earns it as a second step, after the main router is in the best spot the layout allows. Our networking and Wi-Fi work almost always starts with placement before anything is bought.
When Placement Alone Isn't Enough
Some Dundee properties genuinely defeat a single router no matter where you put it. Long thin flats with masonry between every room. Semi-detached houses where the office is in a converted garage across a solid wall. Broughty Ferry villas with two internal chimneys and a stone extension on the back. In those cases, a well-designed mesh with a wired backhaul between nodes, or a couple of ceiling-mount access points, will do what one router cannot.
What we don't want to see is a stack of powerline adapters, Wi-Fi extenders and boosters bought one at a time trying to patch over the problem. Each device adds latency and each one is a new failure point. Two well-placed access points on a wired backbone will outperform five daisy-chained extenders every time.
How We Diagnose Wi-Fi Problems on a Dundee Call-out
When we come out for a Wi-Fi home or office callout, the first thing that happens is a signal survey. We walk the property with a signal-strength tool that reads dBm figures and channel usage at each spot the customer actually uses their devices — the desk, the sofa, the kitchen island, the bedroom. That gives us a map of where the coverage is genuinely weak, where it's fine, and where the router is competing with neighbouring networks on a congested channel.
From that survey we can usually recommend one of three things: move the router (often enough on its own), add a wired access point to the room that isn't reached, or set up a proper mesh with a wired backhaul. For Dundee small businesses, the same survey feeds into what we plan under business IT support — coverage in the shop floor and the office, not just the desk closest to the router.
The Short Version
If your Wi-Fi in Dundee, Broughty Ferry, Perth or St Andrews is patchy, the first question is not what router to buy. It's where the current router is sitting. Move it central, get it up off the floor, get it out of any cupboard or metal enclosure, keep it clear of the TV and set-top box, and see what the coverage looks like then. Nine times out of ten that solves it. The tenth time is when a survey and a proper mesh or access-point setup is worth the trip.
