Step 1: Check whether you have sufficient wireless network coverage
There may be a problem with your wireless network coverage. See below for some potential causes and solutions. An app for testing your wireless network may be a useful way to identify any problems. We recommend ‘WiFi analyzer’ (the app name is the same for Android and iOS).
Potential problem: The device is too far from the router.
Test: Check the performance of your wireless network as you move further away from your router.
Solution: To solve this problem, you can either install a repeater or a new router offering enhanced performance.
Potential problem: Obstructions such as thick walls weaken the wireless network signal
Test: Test the performance of your wireless network on one side of the wall and compare it with the performance on the other side of the wall.
Solution: You can use powerline adapters, which transmit the wireless network’s signal along the building’s existing electrical wiring.
Potential problem: Multiple wireless networks are overlapping in one area. Every router automatically selects and uses a channel. The channels are numbered 1 to 11. In densely populated areas, networks that are using the same channel may overlap.
Test: The app will show you which channels are used most heavily.
Solution: Manually change the channel that your router uses. Select a channel that is not too heavily used. To make this change, read your router’s manual.
Potential problem: There are too many devices using the same wireless network. This can slow down the wireless network’s performance – particularly if users are constantly downloading or streaming videos.
Test: The app shows you how fast your wireless network is.
Solution: Install a router with a higher capacity or use a wireless network router with mesh networking.
