Often, it’s not the line itself but the home Wi-Fi network that’s to blame for internet issues. Numerous factors can affect performance: distance, obstacles, and interference. Many other devices operate on the same frequency band as Wi-Fi. One device, commonly found in many households, can significantly impact transmission: the baby monitor.
Why a Baby Monitor Slows Down Wi-Fi
Modern internet routers with Wi-Fi 6E now support three frequency bands: 2.4 GHz, 5 GHz, and 6 GHz. The latter is considered less crowded, potentially offering more stable and efficient web access. However, routers must still transmit on the 2.4-GHz band, where many older devices and IoT systems—such as smart home outlets and lamps—are located.

But the 2.4-GHz band is also used for countless other applications. Devices with Bluetooth, cordless phones, and even microwaves use these frequency waves. According to “Chip.de,” the baby monitor, in particular, can disrupt the Wi-Fi connection. This can lead to streaming interruptions, slow downloads, and generally make the connection seem less stable. Why baby monitors specifically? According to “Chip.de,” the receivers are often placed close to routers or within their signal range, amplifying the effect.
Improving Wi-Fi Connection–Here’s How
As a first step, increasing the distance between the router and the baby monitor can help reduce interference. Additionally, the router should be placed as centrally as possible to cover all rooms. Covers like metal doors significantly limit signal performance—a freestanding router performs best.
Almost all routers now support the 5-GHz band in addition to the 2.4-GHz band. Fewer devices operate on this frequency, providing more bandwidth for individual users. However, even here, bottlenecks can occur. That’s why modern routers with Wi-Fi 6E or Wi-Fi 7 can also transmit on the 6-GHz band.
Routers often come with different SSIDs (network names) for each frequency band by default. If not, this can usually be changed with a few adjustments in the router settings. Devices that require more bandwidth and a stable connection should be connected to the 5-GHz or 6-GHz band.
