These Android apps are a bit geeky, but they are useful for: Sometimes you need to know the IP addresses of Wi-Fi devices, like a wireless printer, and a Wi-Fi scanner can tell you in an instant. This happens more in the office than at home where employees may bring extra devices to work, but even at home you may find your neighbour is logging onto your Wi-Fi and using it for who knows what.Ī Wi-Fi scanner will look for devices connected to the network and list them so you can check that only ones you have added yourself are present. You may think you know all the devices on your wireless network, but there may be devices that you are not aware of. It may simply involve moving a wireless router a few feet to a better position. Measuring the wireless signal strength around the building can help to identify areas where the signal is poor and would benefit from a boost. Most likely though, they will just work poorly and you will not know why.

The Wi-Fi signal may not reach all parts of the home or office and there could be dead spots where devices do not work at all. Wireless networking is easy in theory, but is sometimes harder in practice. Are there dead spots on your home or work Wi-Fi network? Do you know all the devices that are connected to it? Are the unauthorised devices? These Android phone apps provide the answers.
