How to test Wi-Fi next to a baby monitor

Does Wi-Fi pause or drop when a baby monitor is running nearby? The monitor may be affecting the connection, but a weak router signal, other devices, or a temporary internet problem can cause similar symptoms.

Use the Wi-Fi Signal test to watch response time, jitter, and dropped requests. Compare readings in the same place with the monitor in its usual state, then make one change at a time.

Compare Wi-Fi with the monitor on and off

1. Open Wi-Fi Signal on the computer or device that has the problem. Keep it connected to the same Wi-Fi network throughout the test.
2. Put the device in the location where Wi-Fi trouble occurs. Leave it still, and note the response time, jitter, and any dropped requests while the baby monitor is operating normally.
3. Continue watching the readings for a few minutes. Note any pauses or repeated drops, rather than judging the connection from one brief spike.
4. If it is safe and practical, repeat the test in the same spot with the monitor's wireless transmission off. Do not interrupt monitoring when a child needs supervision. If turning it off is not appropriate, compare two safe locations or test at different times while keeping other conditions similar.
5. Repeat the comparison once more. Keep the device, Wi-Fi network, and test location the same, and change only the monitor's state or position.

If the monitor has a camera unit and a parent unit, think about which one is closest to the Wi-Fi device or router. Test the suspected source without changing the monitor setup in a way that reduces safe supervision.

What the result means

Wi-Fi is worse only when the monitor is operating

If higher response times, more jitter, or dropped requests appear repeatedly with the monitor on, the monitor may be contributing to the problem. The result is a useful comparison, not proof of radio interference. A browser test measures how the connection behaves, and other network activity can change the readings too.

Readings are poor with the monitor on and off

The monitor is less likely to be the only cause. The Wi-Fi path may be weak in that spot, the router or internet connection may be busy, or another device may be using the network. Try the same test closer to the router to see whether the connection improves.

Readings look steady, but an app still pauses

The issue may be in the app or device rather than the Wi-Fi connection. Check whether other apps pause at the same time, and try another device in the same location. A browser test cannot show every cause of a problem inside a specific app.

One or two spikes appear, but the rest is steady

A brief spike by itself does not establish a reliability problem. Repeat the test, and look for a pattern of recurring delays or dropped requests during the monitor's normal use.

How to improve reliability

1. Move the Wi-Fi device a little farther away. Try a different desk position, and keep the laptop or phone away from the monitor's camera unit, receiver, and their power supplies. Retest without changing anything else.
2. Change the router or monitor placement. Put the router in an open, central location rather than behind a TV, inside a cabinet, or on the floor. Keep it away from the monitor units when possible. Test after each move so you know which change helped.
3. Try another Wi-Fi band if your router offers one. Some routers provide both 2.4 GHz and 5 GHz Wi-Fi. The devices may behave differently on each band, and not every baby monitor uses the same wireless technology. Choose the other available network and retest. On Windows 11, open Settings › Network & internet › Wi-Fi to choose a network. On macOS, open System Settings › Wi-Fi. The router may need separate network names for each band.
4. Reduce other network activity for a comparison. Pause large downloads or video streams briefly, if convenient, and run the same test again. If the connection improves, congestion may be contributing alongside the monitor.
5. Restart and update the router. Restart it using its normal controls, then check the manufacturer's instructions for firmware updates. Avoid resetting it to factory settings unless you are prepared to set up the network again.
6. Use a wired connection where practical. If a stationary computer or access point can connect to the router by Ethernet, that removes Wi-Fi from that part of the connection. Retest the wireless device afterward to check whether the local Wi-Fi issue remains.

What this Wi-Fi test can and cannot show

Browsers cannot read the Wi-Fi signal strength in dBm, a unit used by some network tools. Wi-Fi Signal instead measures how the connection behaves through response time, jitter, and dropped requests. Those readings help you compare locations and conditions, but they do not identify the exact source of interference or separate every router, internet, and device issue.

Baby monitors also vary. Some use Wi-Fi, while others use a separate wireless system. A difference between two tests can point you toward a useful placement change, but it does not tell you which radio frequency the monitor uses. Keep the monitor in its normal, safe position while caring for the baby, and make changes only when they do not interfere with supervision.
