My WiFi was great for the first year after having our Lennar built. Last February it all took a dump. i have 1Gb up and down. I have at least 30 Alexa enabled and smart devices requiring the use of my 2.4 band. I try to keep everything other than that on my 5 band. Not to mention every other piece of electronics you can think of. I just left Xfinity for ATT Fiber last week. I am still having the same issues as before I am running the Att Gateway wifi and the 2 Unleashed AP's i have. I also have the Unleashed broken down into 2 separate bands. Please help.
