Where Should You Put Your Router?

General Positioning Principles

Before getting into specific building types, these are the underlying ideas that apply in most situations. They build on each other, so it is worth going through them in order.

• Central Location

A router broadcasts signal outward in all directions. Placing it near the centre of the space means no single area is much further from it than any other. Place it in a corner or against an outer wall and the signal has to travel the full length of the building to reach the far end, which is always going to be the weakest point. In most homes a central hallway or the living room tends to be a good starting point, and in an office a central corridor or the middle of the main working area usually works better than a back room or a spot along the perimeter.

For technicians: it is easy to default to placing the router wherever the nearest power outlet is. That outlet is almost never in the ideal position for coverage it is just where the electrician put it. A short extension cable or a longer patch cable/fiber cable to the router can move the device to a much better spot. It is worth taking a moment to look at the layout before deciding where the router goes.

• Elevation — Off the Floor and Up High

Wi-Fi signals tend to travel outward and slightly downward from the router. A router sitting on the floor is pointing most of its signal into the ground. Raising it to roughly shoulder height (somewhere between one and one and a half metres off the floor) gives it a much better angle to cover the space around it. A high shelf, a wall bracket, or the top of a bookcase all work well. This also helps the signal travel above furniture, which absorbs and deflects wireless frequencies more than most people expect. A row of filing cabinets, a large sofa, or a bed can create weak spots if the router is at the same level as them rather than above them.

• Keep It in the Open— Not Inside Cabinets or Enclosed Spaces

It is very common to find routers tucked inside TV units, behind televisions, or inside meter boxes and electrical cupboards. It looks tidy, but wood, metal, and especially concrete absorb and reflect wireless signals, and placing a router inside a closed space can significantly reduce how far the signal travels. Metal enclosures are particularly problematic metal tends to reflect Wi-Fi signal rather than allowing it to pass through. The router generally does better sitting out in the open on a shelf or mounted on a wall with some space around it. It is also worth noting that the thick reinforced concrete walls typical in Kenyan and Ugandan construction absorb Wi-Fi signal more heavily than lighter building materials. Every concrete wall the signal has to pass through reduces its strength, which is one more reason why central placement matters particularly in this region

• Line of Sight to the Areas That Matter

Wi-Fi passes through walls, but it travels best when there are fewer obstacles between the router and the device connecting to it. When deciding where to place the router, it helps to think about where people actually spend time and use their devices (the desk someone works from, the main seating area, the kitchen) rather than just finding the nearest convenient surface. A position that gives a relatively open path to those frequently used areas will generally perform better than one that puts several walls between the router and where the signal is needed most.

Simple check:  After placing the router, walk to the furthest part of the space with a phone and check the signal strength. If it drops significantly, the router position may need adjusting or the space may need a second access point.

• Distance From Interference Sources

Several common household and office devices share the same 2.4GHz radio frequency that Wi-Fi uses, and placing the router close to them can degrade the signal. The main ones to be aware of are microwave ovens — keeping at least two metres between the router and any microwave is a reasonable precaution — cordless DECT phone base stations, and baby monitors. In dense apartment blocks it is also common for many routers to be broadcasting on the same Wi-Fi channel simultaneously, which creates congestion. A Wi-Fi analyser app can show which channels nearby networks are using, and in the 2.4GHz band, channels 1, 6, and 11 do not overlap with each other, so picking the least congested of those three tends to help. Most modern routers also broadcast on a 5GHz band, which is faster but shorter in range and less effective through thick walls. Keeping both bands active and letting devices connect to whichever suits their location gives the best overall experience.

• Antenna Orientation

For routers with external antennas, orientation does make a difference, though it matters less than the placement itself. The principle is that a Wi-Fi antenna radiates signal perpendicular to its own length a vertical antenna spreads signal horizontally across a floor, while a horizontal antenna spreads it more vertically, which is useful when trying to cover multiple floors. For a single-storey space, both antennas pointing straight up tends to give the widest horizontal spread. For a two-storey home, one antenna vertical and one at 45 degrees or fully horizontal can help signal travel between floors. If the router is wall-mounted, the antennas should be angled away from the wall rather than lying flat against it

How This Looks in Different Spaces

The principles above apply broadly, but what they look like in practice depends on the type of building. Here is how to think through the most common situations.

Apartments

Apartments are generally compact enough that a single well-placed router should be able to cover the whole unit. The challenge is that they tend to have thick concrete walls between rooms, and the available power outlets are often along outer walls rather than in central positions. Placing the router centrally in the living room or hallway, elevated on a shelf or wall bracket, and in open air rather than inside furniture gives it the best chance of reaching every room. In dense apartment blocks it is also worth checking for channel congestion on the 2.4GHz band. For larger apartments with three or more bedrooms, or irregular layouts, a single router may genuinely not reach every corner, and a second access point connected by cable tends to be a more reliable solution than a wireless range extender.

Multi-Storey Buildings

Floors are harder for Wi-Fi to cross than walls, and a concrete floor slab between levels is a significant barrier. For a two-storey home, placing the router on the upper floor rather than the ground floor tends to work better since signal travels downward through a slab more readily than upward, and positioning it near the stairwell where there is a natural opening between floors helps the signal travel without having to pass through concrete. For three or more floors, a single router is generally not enough to serve all levels reliably. One access point per floor, each connected back to the main router by cable where possible, tends to give the most consistent results. Where running cable between floors is not practical, a mesh Wi-Fi system with a node on each floor is a reasonable alternative, as the nodes work together as a single network and devices move between them automatically.

For technicians:  Walking the space before installation and counting the floors makes it easier to have an honest conversation about what one router can and cannot cover. Setting clear expectations early tends to go better for everyone than explaining coverage gaps after the job is done.

Offices and Commercial Spaces

Offices bring two things that most homes do not: more devices connecting simultaneously, and internal partitioning that breaks the space into zones. In an open-plan office, a single router placed centrally and mounted high on a wall or ceiling can typically serve a floor of around 150 to 200 square metres without too much difficulty. Partitioned offices are harder to cover from a single point, and how much harder depends on what the partitions are made of, glass passes signal well, drylining causes some reduction, and concrete block is a significant barrier. A central corridor, if there is one, is often a practical position as it gives a relatively direct path to rooms on either side. It is also worth keeping in mind that coverage is only part of the picture capacity matters too. Most consumer-grade routers handle around ten to twenty connected devices comfortably, and a busy office can easily exceed that. For offices with more than around fifteen to twenty regular users, a business-grade access point tends to be a better fit than a home router.

Final Thoughts

Router positioning is one of those things that is easy to get approximately right and very easy to get quietly wrong. The difference between a good installation and one that generates complaints is often just a matter of taking a few extra minutes to think about the space before deciding where the device goes. Central, elevated, in the open, with a clear path to where the signal is needed — those four things cover most situations. When one router is genuinely not enough for the space, it is better to acknowledge that early and plan for a second access point than to hope the single device will stretch further than it can. The buildings across Nairobi, Kampala, and most of the region are built in ways that make Wi-Fi harder to distribute than in lighter construction, and working with that reality leads to better outcomes for everyone.
