Can't connect smart TV's to wi-fi

[ltucker70]

I have 4 smart TV's and can't get any of them to connect to my wi-fi. I know the wifi works because we have a desktop, laptop, 2 ipads and 2 iphones we use daily with no problems. I also know all 4 TV's can't be wrong because they are all less than a year old and one is actually less than a month old. I have googled for three days and tried every solution out there and nothing works. I want to be able to use amazon and netflix apps but can't get TV to connect. We have Direct TV and it is connected fine to wi-fi and we can watch movies using that internet connection. Any suggestions?

Do I maybe need to change some settings on my hotspot? My husband is going to bring home a different hotspot tonight from work and we will try it so we will know if it's just our hotspot. In the meantime I'm going nuts trying to figure this out.
