Lennar/AT&T configuration

[philip_ciapponi]

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.
