I'm considering buying a bluetooth mouse for my laptop. But I've heard that this can affect the Wi-Fi. Does anyone know if that's true?
Interference can occur because they are transmitting on the same frequency.
Theoretically possible but unlikely because there should be enough channels so that the two don't get in each other's way
Bluetooth and WLAN both transmit at 2.4 GHz. In this respect, there's a possibility that both will disturb each other. However, current Bluetooth devices are capable of so-called adaptive frequency hopping. You try to avoid channels that are already in use and avoid the WLAN. However, if the frequency spectrum is used very heavily, collisions will inevitably occur.
A correct and good answer!
Personally, I would prefer a wired mouse to avoid this problem in advance.
