I have been having the same problem too! Recently after updating my XR to iOS 14.2, I’ve been having wifi connection issues on my phone. I never had this type of problem for almost a year. I had to literally restart my phone at least 5 times so that my phone would be able to connect with the internet. When it doesn’t connect to the wifi, my data on LTE stops working too. I believe this is an issue with the new update on the phone because like I said, I never had this problem before. Please fix this ASAP as it’s getting very frustrating!!!!
