Two iPhone 12's, one connects to wifi, another does not.

I have a lot of knowledge in networking. My wife and I just got 2 brand new iPhone 12s. Our internet at the house is rock solid, no issues. My phone connects to the wireless router with no issues and I can do all things wifi. My wife connects to the same router, and she will get frequent messages that she is connected, but has no internet access. This is very strange to me. I tried forgetting the network, but same issue. I verified that we are getting different IP addresses and that our host names are not similar. This definitely seems to be an issue with 2 of these iPhones connecting to the same network. Her wifi works great in other areas, and so does mine.

Has anyone heard of this issue where 2 iPhones on the same network having a similar type of problem?
