Tether APP internet speed test not accurate
The app speed test is garbage.
App shows speeds between 400-500 range.
Ookla on my Pixel 6 Pro 700+
Ookla on Apple TV hardwire to router 900+
App needs to be fixed, don't go by it and call your ISP, you might get charged for the visit.
The speeds you get on the app is way lower than actually is.
