Everyone says “put your router in a central location” and leaves it there, which is true but not very useful on its own. Here’s what that actually means once you get into a real house with real furniture and real walls.
Central doesn’t mean the exact geometric middle
It means central relative to where you actually use the internet. If your bedroom and home office are both on one side of the house and nobody ever goes in the guest room on the other side, “central” for you might be a spot that’s off-center on a floor plan but perfectly placed for how the home is actually used.
Height matters more than most people realize
Signals spread outward and downward more than upward. A router on the floor is fighting gravity and furniture from the start. Getting it up to roughly shoulder height — a shelf, a mounted bracket, the top of a bookcase — genuinely changes how far the signal reaches without any other change.
The kitchen is where WiFi goes to die
Metal appliances act almost like a shield for wireless signals, and a microwave running on the same frequency as your 2.4GHz band causes real, measurable interference while it’s on. If your router has to be anywhere near a kitchen, keep as much distance from the fridge, oven, and microwave as the layout allows.
What actually blocks a signal, ranked roughly by how bad it is
Concrete and brick are the worst. Metal furniture and appliances are close behind. Standard drywall barely matters. Water — think a large fish tank — absorbs signal more than people expect. Mirrors can reflect signal in ways that create unexpectedly weak spots on the other side of a room.
Multi-floor houses need a different approach entirely
A single router, however good, struggles to push a strong signal through more than one floor’s worth of construction. If you’re in a two or three-story home, either placing the router on a middle floor (so the signal has less distance to travel in both directions) or moving to a mesh system with a node per floor solves this far more reliably than repositioning a single unit ever will.
Antenna orientation, if your router has external ones
Vertical antennas broadcast better across a single floor. If you need coverage both up and down, angling one antenna horizontally and leaving the other vertical spreads the signal across more planes — a small adjustment that’s easy to skip entirely if you don’t know it’s an option.
Actually mapping your dead zones instead of guessing
A free WiFi analyzer app on your phone will show you signal strength as you walk from room to room. It takes about ten minutes and tells you exactly where the weak spots are, rather than relying on a vague sense that “the back bedroom feels slow.”
A short checklist before you call it done
Router is roughly central to where you actually spend time, not necessarily the floor plan’s center
Elevated to about shoulder height or higher
At least a few feet from the kitchen’s metal appliances
No cabinet, no cupboard, nothing enclosing it
Firmware checked and updated while you’re already in the settings
Fixing placement costs nothing and it’s the first thing worth trying before assuming you need new hardware. It won’t solve every coverage problem in a large or oddly-shaped home, but it solves more of them than people expect.
