What to check before adding an access point upstairs

Wi-Fi works downstairs, but upstairs calls pause, pages take too long to load, or a bedroom barely connects. Before buying an access point, check which rooms actually have a problem and where a new device could get a reliable connection.

The Wi-Fi Map lets you measure connection quality in different rooms. Use it to make a baseline with your current router, then choose a location based on how you plan to connect the access point.

Map your current upstairs Wi-Fi

Open the Wi-Fi Map on the laptop or phone you normally use upstairs. Keep it connected to your home Wi-Fi, not cellular data or a different network.
Start with a spot near the router, then measure at the top of the stairs, in the hallway, and in the rooms where you notice trouble. Write down each location and the result you see.
Measure in the place where you use the device, such as beside your desk or bed. Keep the device in roughly the same position and orientation for each reading.
Repeat the readings that look unexpectedly poor. Check once with doors open and once with them in their usual position, especially if a closed door is part of the problem.
Mark one or two possible access point locations on your notes. Measure there too, rather than assuming the best spot is the room with the weakest Wi-Fi.
After installing an access point, repeat the same route with the same device. Compare the rooms that matter, not just the reading next to the new unit.

A simple list of rooms and results is enough. The goal is to see where the connection gets worse and whether a proposed access point location still has a dependable link to the existing network.

What the results mean

The connection is good near the stairs but poor in a bedroom

The signal reaches upstairs, but walls, distance, or the room layout may be weakening it before it reaches the place you need. An access point placed in the hallway or near the bedroom may help. If it uses a wireless connection to the router, test that proposed spot carefully: the access point needs a usable connection there too.

The connection is already poor at the top of the stairs

A wireless access point placed upstairs may also struggle to communicate with the router. A wired Ethernet connection from the router to the upstairs access point is usually a more dependable option because it does not rely on that weak wireless link. If running cable is not practical, look for a spot between the router and the problem rooms where the existing connection is still usable.

Every upstairs room is slow or unreliable

Do not assume coverage is the only cause. If the connection is also poor near the router, the issue could be the internet service, router, or an interruption affecting the whole network. Test again near the router and compare at another time before buying new hardware.

The results change from one reading to the next

Small changes in position, nearby devices, and other people using the network can affect a measurement. Repeat the same location a few times under normal household conditions. Look for a consistent difference between rooms, not a single unusually good or bad result.

What to adjust before buying an access point

Confirm the device is on your home Wi-Fi. A guest network or an old saved network can behave differently. On Windows 11, check Settings › Network & internet › Wi-Fi. On a Mac, check System Settings › Wi-Fi. Make sure you compare readings on the same network.
Move the router to a more open spot. If it is inside a cabinet, on the floor, or behind a television, move it higher and clear of large obstructions if you can. Rerun the map before deciding you need another device.
Test the route between floors. Measure in the stairwell and at the landing, not only in the rooms at either end. A wireless access point needs a good location between the router and the weak rooms, rather than being hidden in the weakest corner.
Choose wired or wireless backhaul. Backhaul is the connection from the access point to the router. If you can run Ethernet upstairs, place the access point where it can cover the rooms you use. If it must connect wirelessly, place it where your map still shows a usable connection to the router.
Check whether one room or the whole floor needs help. For one isolated room, a carefully placed access point may be enough. If several rooms and the landing are poor, plan for the route the new device needs to cover, and confirm the equipment can connect to your existing router.

Why the map is not a signal-strength meter

A browser cannot read the Wi-Fi radio signal level in dBm, the unit often shown in router or network diagnostic apps. Wi-Fi Map measures what the connection does, including response time, jitter, and dropped requests. These results help you compare locations, but they do not identify the exact wall, interference source, or router setting causing a weak result.

That is why the same device, same network, and repeated locations matter. A map can show that a bedroom is less reliable than the landing. It cannot guarantee that a particular access point model will fix the room, so use the baseline to choose a sensible placement and verify the change afterward.

Keep your before-and-after notes, and check the rooms where you work, stream, or take calls after the access point is installed.
