How can I fix Wi-Fi and CarPlay issues on iPhone 17 Pro Max?

Hi All, starting this thread as I purchased an iPhone 17 Pro Max today. Obviously it’s launch day so there’s not too much information on bugs as iOS 26 has recently come out in conjunction with the release of this phone. However, I’ve noticed some issues with my new phone and was wanting to see whether this is a ‘just me’ issue or it seems to be impacting other users.

Ive noticed that my wifi consistently was dropping in and out on setup and that my wireless apple carplay seems to disconnect intermittently.

I have tried a network settings reset with no resolution (twice) but would be really frustrated to have to reset my phone completely after transferring all my data across to my new phone.

I may end up returning this device and getting another one if any further issues persist whilst the return window is still an option.

People on the MacRumors forum are experiencing the same issues, and most of them are blaming the new WiFi chip. Apple really let us down this time. If they are working on a solution, why not come out and say it? There’s an article coming out in our local town newspaper warning people to hold off on upgrading to the new iPhone 17. Maybe this will catch momentum with it being discussed on X and other platforms. Perhaps Apple will take notice and create a sense of urgency.
