Solution #2: Be mindful of other devices
As we mentioned, other electronics can interfere with the signal but so can other things you might not immediately think about – things like microwave ovens and even window air conditioners can have an adverse effect on your WiFi signal. Basically, anything with a motor or moving parts that require electricity to operate can mess with a WiFi signal.
Make sure that your router is positioned at least 3 feet from anything that could compete with or absorb the signal. Oddly enough, that’s all it really seems to take.
