How to find a weak Wi-Fi corner in an open office

Does a video call freeze at one desk, or does a laptop lose its connection in a corner of an otherwise usable office? In an open-plan space, a few feet, a tall shelf, or a busy row of desks can make a noticeable difference.

Use the Wi-Fi Map to compare connection quality at different spots. A consistent walk-through can show whether one area is worse than the rest, or whether the whole office is having trouble.

Map Wi-Fi quality around the office

1. Open the Wi-Fi Map on the laptop or phone that has the problem. Keep Wi-Fi enabled and connect to the office network you normally use.
2. Sketch a simple floor plan or make a list of test spots. Include the unreliable corner, the nearest open area, the center of the office, and a spot near the access point if you know where it is. If you do not know its location, use a desk where Wi-Fi is usually reliable.
3. At each spot, measure with the tool and wait for the reading to settle. Note the location and whether the map shows good or poor quality. Also note response time, jitter, or lost requests when those readings are available.
4. Keep the device in the same position and orientation at every spot. Avoid walking around during a reading, and do not switch between the office network and a guest network halfway through the test.
5. Return to the unreliable corner and test it again. Repeat the route later if the office is much busier at another time of day.

For a useful comparison, test the same spots in the same order. People, open doors, movable partitions, and active downloads can all change the result. Write down anything that changed between rounds.

What the results mean

One corner is consistently worse

If nearby desks have steady readings but one corner repeatedly shows higher delays, more jitter, or lost requests, the problem is likely local to that area. A wall, metal cabinet, shelving, or the distance and angle to an access point may be weakening the connection. Share the map and the affected desk locations with whoever manages the office network.

Every spot has similar poor readings

If the corner is no worse than the rest of the office, the problem may not be a coverage dead spot. Network congestion, the internet connection, or a problem beyond the office Wi-Fi could affect every location. Compare your results with a wired connection or ask the network administrator to check the office connection.

The readings change a lot between rounds

Large changes can point to variable interference, network congestion, or a device moving between access points. They can also happen when other people start using the network. Repeat the same route at a quieter time and during a busy period, and note when the issue occurs.

The map looks fine, but one app still disconnects

A generally healthy connection does not rule out a problem with a particular app, VPN, or service. Check whether other websites and apps also pause at that desk. If only one service fails, report that symptom separately instead of treating it as proof of a Wi-Fi coverage problem.

How to improve the weak area

1. Repeat the comparison without changing networks. Check that the device is still connected to the same office Wi-Fi network at every spot. On Windows 11, open Settings › Network & internet › Wi-Fi. On a Mac, open System Settings › Wi-Fi.
2. Move the device into the open. Test on the desk rather than inside a cabinet, behind a monitor, or under a table. If that improves the reading, keep the device clear of the obstruction when possible.
3. Check for a nearby obstruction. Look for metal shelving, filing cabinets, thick walls, or equipment between the desk and the access point. Do not move office network equipment without permission, but report any clear obstruction to the person responsible for it.
4. Compare another device at the same desk. If another laptop or phone is steady there, the issue may be specific to the original device, its Wi-Fi adapter, or its settings. If both devices struggle in the same place, the location or office network is more likely involved.
5. Ask about access point placement or capacity. Give the administrator your location notes and readings, including the time of day. They can decide whether to adjust an access point, add coverage, or investigate congestion.

What the map can and cannot measure

A browser cannot read the Wi-Fi radio signal strength in dBm. The Wi-Fi Map measures what the connection does instead, such as response time, jitter, and lost requests, to help compare how well different spots work in practice. Those results are useful for finding a corner that behaves poorly, but they do not identify the exact cause by themselves.

For a fair test, use the same device and network, keep your route consistent, and avoid running large downloads during one round but not another. If the problem matters for calls or other live work, test at the times you actually use that desk.
