First of all, it is important to measure the speed of your internet connection where you want to install your smart device. This is possible with the help of a speed test. You can learn more about this in our article about performing a speed test.
If your speed is fast enough, it is also smart to test the channel using a Wi-Fi analyser. You can download and use a Wi-Fi analyser app where you want to install your smart device.
You can use the analyser to find the best channel or place for your router / access point by simply analysing your wireless network with a mobile device. The test may show that you may have to change channels. Your internet provider can often help you with this.
