iPhone Xs has troubles showing "No Internet Connection", and there isn't.
My wife has an iPhone Xs and I have an X. She often has problems with her phone telling her it has no internet connection and in fact it does not. Pages will load, but the images and details will not. At the same time in the same location my X works fine as does our iPad 6 running 18.3.1. My phone is running 16.7.10 and her phone is running 18.3, both the newest each model allows. She can clear the problem with a reboot, but it occurs again, sometimes in a few days, sometimes more and occasionally immediately after the reboot. Our current router is an TP Link 5260, recently installed but her problem existed prior to the replacement. Our ISP is our cable company, Spectrum.
