One router rarely covers a whole office. Walls, metal, and distance weaken the signal. The reliable fix is business access points connected by network cable and placed where people work. Extenders are a cheaper patch but often halve speed.
Common causes
One router for the whole space
A single router in a closet or corner can't cover multiple rooms, floors, or long buildings.
Building materials
Concrete, brick, metal studs, filing cabinets, and glass block or absorb WiFi signal.
Router placed badly
Routers inside cabinets, on the floor, or behind equipment lose much of their range.
Interference from neighbors
In office buildings, dozens of nearby networks on the same channels reduce usable signal.
How to fix it, step by step
- 1
Move the router to an open, central spot
Raise it off the floor and out of cabinets. Even small moves can improve coverage noticeably.
- 2
Map where the signal drops
Walk the office with a phone or WiFi analyzer app and note where speed and signal fall off.
- 3
Change the WiFi channel
On 2.4 GHz, use channel 1, 6, or 11 — whichever is least crowded. Let 5 GHz choose automatically or pick a clear channel.
- 4
Add a wired access point
For permanent coverage, run a network cable and install a business access point where the signal is weak.
- 5
Use mesh only where cabling isn't possible
Mesh systems work without cables, but each wireless hop reduces speed. Wired backhaul is best.
When to call a technician
If your office has more than a few rooms or multiple floors, a proper access point layout saves money compared to trial and error with extenders. We survey the space, recommend where access points should go, and handle the cabling and setup.

Frequently asked questions
Are WiFi extenders good for offices?
They can fill a small gap, but most extenders cut speed in half and cause devices to stick to the wrong signal. Wired access points perform much better.
How many access points does an office need?
It depends on size, walls, and the number of users. A typical small office may need two to four. A site survey gives the right answer.
Is mesh WiFi good for business?
Business mesh systems can work well, especially with cable connecting the units. Consumer mesh often struggles with many users.
