Massive WiFi problems after ios18 update.

I have an iPhone 15 pro max, and my wife has an iPhone 15 pro plus an iPad Pro 10.5”. We also have Xfinity F1 internet service with all the correct router and extender xfinity pods.

After the current update to iOS 18 all of our devices have difficulty connecting to WiFi if I move from the Gateway connection to the xfinity pods connection. Says “unable to connect to WiFi” or two many devices on WiFi check router.

I contacted Comcast Xfinity and they came and charged my gateway router and checked the two xfinity pods and said everything was working properly. The problem is with the new Apple ios18 update.

I called Apple and they advised they are still “working on it”.

Hope they can fix this soon.
