Where a router sits is the first thing worth checking when coverage is uneven, and it is the change that costs nothing. Wi-Fi signal weakens as it passes through material, and it spreads outward from the router rather than being aimed. A device tucked behind a TV in one corner of the house is asking to leave the opposite corner with little to work with.
Why the install location is rarely the best location
Internet service in many Canadian homes terminates wherever the cable, fibre, or DSL line enters the building. That is often a basement utility area, a cold room, or a closet near an exterior wall. Those spots are convenient for the technician and poor for coverage: signal heading upward must cross a floor, and signal heading inward is partly blocked by the surrounding structure.
Older houses and many condo buildings use concrete, brick, or plaster with metal lath. These dense materials absorb and reflect Wi-Fi far more than interior drywall. A router two rooms away through standard walls may perform well, while the same distance through a concrete core or a brick chimney can drop the signal sharply.
Materials that tend to weaken the signal
- Concrete and cinder block, common in basements and condo cores
- Brick and stone, including fireplaces and chimneys
- Plaster walls reinforced with metal lath in older homes
- Large mirrors, metal appliances, and metal ductwork
- Water, which means full bathtubs, aquariums, and even densely occupied rooms
A practical placement checklist
- Move toward the centre. A central location shortens the worst-case distance to any room.
- Raise it. A shelf or wall mount usually beats the floor, since the signal then travels across rooms rather than through furniture.
- Keep it in the open. Avoid cabinets, media consoles, and the space directly beside metal appliances.
- Favour the living space, not the storage space. If the line enters a basement, a length of cable to a main-floor spot is often worth it.
- Mind the antennas. If the router has external antennas, a mix of vertical and angled positions can help cover multiple floors.
For a multi-storey detached home, a router on the main floor in a central hallway frequently covers both the basement and the upper floor better than a basement install ever could.
Apartments and condos
In a smaller unit the distances are short, so the bigger issue is usually neighbouring networks rather than your own walls. Even so, keeping the router away from the suite's structural core and out of a closet still helps. Placement and channel choice work together here; the companion note on channels covers the interference side.
When placement is not enough
If the home is large, long, or split across several floors with dense materials, a single well-placed router may still leave gaps. At that point adding coverage with a mesh set or a wired access point is the logical next step rather than continuing to move one unit around.
