How to fix Xfinity Wi-Fi issues with iPhone 16 Pro Max?

l have received no resolution and useless responses from Xfinity on WiFi connectivity problems after my modem was replaced. Apple went as far as replacing my iPhone 16 pro max even after firmly believing it was an Xfinity issue. I have tried every form suggestion both on Xfinity and Apple.

Is the only solution to add a mesh router, and if I do, will it support the Xfinity camera and security system?

And no issues on WiFi with my phone outside of my home when connected to Xfinity.

Unfortunately, the router reverts settings like every day and re-enables wifi6 every time. Sigh. If I can’t find a way to permanently disable it, I may have to get a separate mesh router

Pieterw - yes, my router reverted back and automatically re-enabled the 6Ghz after a few hours. Frustrating!! Please report back if you find a way to permanently disable it.

Try downloading the Xfinity app and restart your gateway modem
