A typical 2,800 sq ft two-storey home with a basement needs 2 to 3 mesh units (the router plus one or two nodes) in drywall construction, and up to 5 in brick or concrete. The table below calculates units for seven home types using three planning values: about 1,500, 1,000 or 600 sq ft of coverage per unit depending on walls. These are planning estimates, so test the rooms you use after setup and move a node if a spot is weak.

- Units needed by square footage, floors and walls
- What a 2-pack, 3-pack or 4-pack covers
- Placement distances and the hop penalty
- When more nodes make WiFi worse
- Wall material changes the answer more than square footage. The same house can need 2 units in drywall and 5 in concrete.
- Plan at least one unit per floor when walls are dense, and place basement and upstairs units roughly under or over the main one.
- Each wireless hop on a shared band can cut speed by up to half, so three nodes in a chain is a poor design.
- More units are not always better. Past the number the table shows, extra nodes add interference instead of coverage.
You are about to buy a mesh kit and want to know whether a 2-pack, 3-pack or larger set matches your home.
You have one dead room. A single repositioned router or one extra unit may be enough. See mesh WiFi vs WiFi extender.
How many mesh units does each home type need?
“Units” counts the main router unit plus every node. Pick the column that matches your walls: drywall with open rooms, a home with many interior walls or plaster, or brick, concrete and insulated-concrete-form (ICF) construction.
| Home type | Size | Floors | Open drywall | Many walls or plaster | Brick or concrete |
|---|---|---|---|---|---|
| Studio or 1-bed condo | 700 sq ft (65 m²) | 1 | 1 | 1 | 2 |
| 2-bed condo | 1,100 sq ft (102 m²) | 1 | 1 | 2 | 2 |
| Townhouse | 1,600 sq ft (149 m²) | 2 | 2 | 2 | 3 |
| Bungalow with finished basement | 2,400 sq ft (223 m²) | 2 | 2 | 3 | 4 |
| Two-storey with basement | 2,800 sq ft (260 m²) | 3 | 2 | 3 | 5 |
| Large two-storey with basement | 3,500 sq ft (325 m²) | 3 | 3 | 4 | 6 |
| Very large house | 5,000 sq ft (465 m²) | 3 | 4 | 5 | 9 |
Size is total finished area including the basement. If the answer in the last column is 6 or more, a wired design with access points is usually steadier than a mesh chain. See access points vs mesh WiFi.
How is the table calculated?
The model has two rules. First, units = total area divided by coverage per unit, rounded up. Second, a floor minimum: with open drywall one unit can serve about two floors, and with denser walls each floor needs its own unit. The larger of the two numbers is shown.
| Wall type | Coverage per unit | Floor minimum |
|---|---|---|
| Open drywall, few doors closed | 1,500 sq ft (139 m²) | 1 unit per 2 floors |
| Many walls, plaster-and-lath, closed doors | 1,000 sq ft (93 m²) | 1 unit per floor |
| Brick, poured concrete or ICF | 600 sq ft (56 m²) | 1 unit per floor |
Worked example, a 2,800 sq ft two-storey with basement (3 floors): open drywall gives max(ceil(2,800 ÷ 1,500), ceil(3 ÷ 2)) = max(2, 2) = 2; many walls gives max(ceil(2,800 ÷ 1,000), 3) = 3; brick or concrete gives ceil(2,800 ÷ 600) = 5. These coverage values are planning assumptions, not product specifications. Check your product’s datasheet and test on site.
Which kit size matches?
| Units needed | Buy | Typical price | Note |
|---|---|---|---|
| 1 | Single router | $120 to $350 | A mesh kit adds cost with no benefit |
| 2 | 2-pack | $250 to $450 | Router in the middle, node at the far end or upstairs |
| 3 | 3-pack | $350 to $700 (WiFi 6 class) | The common choice for two floors plus a basement |
| 4 or more | 3-pack plus an add-on node, or wired access points | $550 and up | Plan wired links between units where cable exists |
Prices are market estimates, not a fixed Pixl price. Pixl sets up the system you buy and can tell you how many units to buy if you text the home size and floors. For the full cost picture, see WiFi installation cost in Canada.
Why do too many nodes in a chain slow WiFi down?
When a node talks to the router and to your phone on the same radio band, it cannot do both at once. Manufacturer guidance describes this as cutting throughput by up to half per hop. The table applies that rule of thumb to a connection that starts at 900 Mbps at the router. Systems with a dedicated backhaul radio or a cable between units do not lose speed this way.
| Position | Shared-band backhaul | Wired or dedicated backhaul |
|---|---|---|
| At the router | 900 Mbps | 900 Mbps |
| First node (1 hop) | 450 Mbps | Close to 900 Mbps |
| Second node (2 hops) | 225 Mbps | Close to 900 Mbps |
| Third node (3 hops) | 112 Mbps | Close to 900 Mbps |
Place nodes so each one connects straight to the main unit, like spokes, rather than daisy-chaining through a middle node.
Where should each unit go?
- Put the router unit near the middle of the home, in the open and off the floor, not in a closet or the basement corner where the modem enters.
- Place each node about halfway to the dead area, where it still gets a strong signal from the router. A node placed inside the dead zone passes on a weak link.
- Stack floors. A basement node roughly under the main unit and an upstairs node roughly over it keep the vertical path short.
- Keep units clear of metal, appliances, fish tanks and thick masonry.
- Test where you use WiFi: the home office, the TV and the bedrooms. Move one unit at a time and test again.
For doorbells and cameras at the edge of the signal, use the checklist in WiFi dead zones for doorbells and cameras.
Mesh WiFi nodes: frequently asked questions
How many mesh nodes do I need for a 2,000 sq ft house?
Two units in an open drywall home or one with many interior walls, and up to four in brick or concrete. The count depends on floors and wall material as much as on area.
Is a 3-pack enough for a three-storey home?
Usually yes in drywall, with one unit near the middle of each floor. In concrete or brick, plan on more, or use wired access points.
Do I need a node in the basement?
If you use WiFi there, yes in most homes. Floors and foundation walls absorb signal, so a node near the foot of the stairs usually helps more than a second unit upstairs.
Can I add more nodes later?
Most systems allow it within the same brand and family. Check the datasheet for the maximum number of units.
Do more nodes always improve coverage?
No. Extra nodes close together compete for the same channels and can slow the network. Add nodes only where a room tests weak.
Should I use a cable between nodes?
Where a network cable already reaches the spot, yes, a wired link is faster and steadier. Pixl does not run new network cable, so a new run goes to a cabling contractor.
Will Pixl tell me what to buy?
Text the home size, floors and wall type and we will tell you how many units to buy. Pixl sets up the system you choose and gives a fixed quote from photos before booking.
Not sure how many units to buy?
Text the size of the home, the floors and where the modem sits. You pay after the job.

Sources and method. Units = max(ceil(area ÷ coverage per unit), floor minimum), calculated in Python with coverage of 1,500, 1,000 and 600 sq ft per unit. Floor minimum = ceil(floors ÷ 2) for open drywall and the number of floors for denser walls. m² = sq ft × 0.0929. The 50 percent loss per shared-band hop is a rule of thumb from manufacturer guidance, not a measurement of your system. Prices are market estimates, not a fixed Pixl price.
