Bluetooth speakers and other wireless gadgets placed too close to a router could interfere with Wi-Fi signals, potentially slowing connection speeds and causing interruptions. Moving the router away from such devices may help improve performance before calling a broadband provider or upgrading a package.
Why Bluetooth interferes with Wi-Fi
Bluetooth and some Wi-Fi connections use similar radio frequencies, meaning the signals can compete for space and interfere with one another. Audio-Technica explains that when too many signals operate close together, devices can struggle to find clear space to communicate.
Its support page states: "Many Wi-Fi routers transmit on multiple channels simultaneously, and if there are excessive Wi-Fi signals in close proximity taking up most of the spectrum, your Bluetooth devices may not have any open spectrum to frequency hop to. This is a common cause of Bluetooth interference. Moving your Bluetooth devices away from Wi-Fi signals will help maximise the performance."
Router placement and other interference sources
Router position around the house also matters. Keeping it in a central, open spot can help the signal reach more rooms, while thick walls and large obstacles may weaken the connection.
The kitchen can be another problem area, as microwaves can interfere with Wi-Fi signals, particularly when both operate on the 2.4GHz frequency band. If internet drops out when food is being heated, moving the router further away from the microwave and other electrical appliances may help.
