My Carrier said that my iPhones are blocking my wifi strenght, is true?
Every night, starting at 7:30 p.m. (Central Time), my wifi speed goes down from 5Mb to 1Mb, my Carrier (CLARO), said me that my iPhones (I have 4 iPhones) are blocking/interfering with the wifi signal. They said to me that I have to reset all the iPhones to Factory Reset and that will help me.
The weirdest thing is that only happens at 7:30 p.m. to 10:00 p.m., then I get back my 5Mb in home. I used iPhones since 3 years and this is the first time it is happening. During the mornings and afternoons, I can use all my devices, including 3 laptops, 1 iPad, 1 wifi printer and everything is ok.
Can you help me guys, to confirm if someone else is having this kind of issue, please?
