That’s different from the “old days” where a router often had a separate network for each of these signals.
Remember, mesh Wi-Fi networks combine both 2.4 GHz and 5 GHz frequencies into a single network. The other piece to this puzzle is the Wi-Fi chips used in many smart home devices.
This is a two-part problem directly related to the growing number of mesh Wi-Fi networks, which is what Mike is using in his home. It also turns out that this is a common problem, even though Wi-Fi smart lights, switches, doorbells and other devices are built around Wi-Fi standards, and therefore should just work on the network. It turns out that he’s having issues connecting them to his home Wi-Fi network, which is built around a Google OnHub. On last week’s IoT Podcast, our voicemail hotline got a question from Mike about his smart Christmas lights.
