so i got an echo dot a month ago, and i'm now trying to add some smart devices. i'm trying to add a smart power strip. when i try to connect to the echo, it doesn't find it. when i use the device's suggested app, i get a message saying that it only connects with 2.4ghz wifi. my wifi apparently switches between 2.4 and 5, but when i'm trying to connect my device, apparently it's the 5ghz. i've read that i could adjust my home wifi to strictly 2.4, but i'm hesitant to do this. first, how do i do it, and second, will it interfere with the video games my boyfriend plays? i can find nothing that works with 5ghz wifi.
