Why does this Samsung Galaxy S5 keep dropping wiFi?

[StrawberryGrandma]

I have taken the phone in on numerous occasions to no avail. My service us through AT&T MI. They don't know how to fix it. I even went to Samsung people, Heck they don't even know how to fix it. This is rediculous. It's worthless. I never should have changed from apple. My husband has the same phone purchased at the same time, his lucky doesn't do it. I want it fixed now!!## To top things off I receive a letter from AT&T mobile they are no longer going to honor what was suppose to be lifetime rate and unlimited service!
