If someone were to ask you to name the five most important things you need in your daily life, it is easy to guess that Wi-Fi connection will be a part of the list.

While some may frown upon how there are other kinds of stuff that are more important, the fact is that the Internet has become integrated into our daily life.

Having Wi-Fi can be a joy or sorrow depending on the speed of the connection. While cruising through the web with a fast Wi-Fi can be the most satisfying thing in life, having to wait for minutes for a page to load, thanks to your slow Wi-Fi can be the most frustrating thing ever.

The reasons for slow Wi-Fi can include the position of your router, the amount of wireless interference and noise, your neighbor’s wifi as well as your household usage. In terms of the position of your router, it is generally accepted that the higher your router is placed, the better your wifi signal and speed.

Similarly, materials such as concrete and metals have been known to block WiFi waves, so make sure that objects and electric devices do not block your WiFi router. Your distance from your router also plays a huge part in determining your WiFi strength and speed.


If you have microwave ovens, Bluetooth devices or even Christmas lights around your room, then these are the culprit for your slow WiFi speed, as these create their own electromagnetic field which interferes with the Wifi signal.

For a 2.4 GHz wireless signal (most common router broadcast frequency), there is typically only 14 channels to broadcast on. More than one router broadcasting on the same channel can result in interference and cause slow WiFi strength and speed.

Lastly, your own household use can adversely affect your WiFi speed. If you have a humongous download running on your PC and expect your mobile device to experience fast WiFi speed, needless to say, you are the cause of your own slow WiFi.

Then the only way to speed up your WiFi is to stop your download. In cases where you have a ton of people using your WiFi, then the users take up all your bandwidth and as a result, if you are facing slow WiFi issues, then WiFiKill apk is the app for you.
