FaceTime problems on WiFi

[ejfontenot]

ok, so this one has been bugging me for a while. When we FaceTime with my in laws, if we are both on WiFi, they get a slow connections warning on their side. If I switch to cellular, no problem. They are running the most up to date iOS for their devices (I updated them when they visited last).

I have a solid WiFi connection here, speed tests are fine. I can FaceTime with my own devices on WiFi here fine. I can FaceTime fine with devices if we are both on their WiFi. I haven’t tried using another WiFi network, maybe I should. This has been going for over a year.

Anyone else have this issue? And it’s every device in our house. iPhones of varying age. iPads of varying age.

What’s your upload speed?

What’s your upload speed?

2.24 on a WiFi. 7 on cellular.
I have used FT in much more limited bandwidth settings on WiFi (hotels in Europe) with no issue.

It’s really not much but should be enough. Question is, how stable it is then. Is your internet connection cable or air based?

It’s plenty fast. Att U-verse. House is hot mapped for ideal WiFi coverage. Eero mesh network. Doesn’t matter where in the house the iPad is connected. And it only happens with my in laws while they are at their house.

It must be on their end then.

I would tend to agree, but the connection is perfectly fine when I switch to LTE.

As I said, I have been racking my brain over this one. I have worked on their network, done speed tests all over their house (they are always in the same place when we FT). Tried multiple devices. It’s the craziest thing.
