Wi-Fi is a great convenience but when it doesn’t work properly it can be difficult to find out what’s going wrong. You may be surprised to know that your kitchen appliances may be the culprit?
Many microwave ovens use electromagnetic waves of 2.4 GHz to heat food which is, by coincidence, the same radio wave as used by traditional internet routers.
Although minor leakages are normal and not harmful to humans, it can be enough to interfere with your WiFi signal which is of much weaker power – don’t worry, your WiFi isn’t going to slowly cook you.
Modern routers also operate at 5GHz which is less susceptible to interference though so select this band if it is an option and your devices are compatible.
The motors on the inside of a fridge can also cause disturbance with WiFi signals. The ice within can also act as a barrier. Keeping your router away from the fridge/freezer is always a good idea therefore.
Large coils within the motor can create electromagnetic interference under heavy loads (such as during the spin cycle) that will cause your WiFi to drop-out so avoid using your washing machine at times when you need an uninterrupted signal.
If you really can’t avoid any of the above scenarios then it makes sense to use a cable connection wherever possible since these are much more stable and less prone to disturbance from external factors.
