Will one Wi-Fi router cover your home?
Estimate whether a single router is likely to provide reliable indoor coverage based on area, floors, walls, router placement, and the Wi-Fi band you expect to use.
Describe the space you want to cover
Use the approximate indoor area where you want consistent Wi-Fi, not the total property size.

How the Wi-Fi coverage estimate works
The calculator begins with a conservative indoor reliable-coverage allowance for a well-placed router, then adjusts it for wall type, multiple floors, router placement, Wi-Fi band, and outdoor edge requirements. The result is intentionally more conservative than maximum vendor range claims.
Why placement changes coverage so much
A router in the middle of the home can distribute its useful signal in more directions. A router in a corner, cabinet, or behind large objects wastes part of its coverage outside the area you care about or forces the signal through unnecessary obstacles.
Why one router can cover the area but still feel slow
Coverage is only one part of Wi-Fi performance. A distant device may remain connected but have lower modulation rates, more retransmissions, and less stable throughput. That is why this tool estimates reliable usable coverage rather than the farthest possible connection.
When to add another access point or mesh node
If your area is larger than the estimated reliable coverage, or if you have heavy walls, multiple floors, or long layouts, an additional Wi-Fi point may be more effective than upgrading to a faster internet plan.
