Start with the basics when setting up a new Wi-Fi router, there is the easy way, which will result in poor security, and then there is the slightly more involved route. Everyone has a Wi-Fi transmitter in their home, all of your neighbours, this can lead to a lot of interference. So, a good place to start is by downloading a Wi-Fi Analyser program on to your phone or computer…Many of the functions created at the open-source level are later ‘adopted’ by industrial firmware providers, by which point opensource firmware has superseded it again.
