IOS 15.1.1 connected to Wi-Fi but “no internet connection”

Ever since the iOS 15 upgrade on my brand new iPhone 13 Pro. I have been having issues staying connected to my Wi-Fi which is a Eero Mesh Pro 6 environment. I will be connected fine for a while pushing up and down speeds of around 326mbs then it will just halt and go to around 20mbs then when I go to Wi-Fi page I see “no internet connection”. As shown in picture below. This has also given the same issue on my 2016 iPad Pro since the iOS 15 update. All my other devices in the house have no internet issues including older iPad that aren’t on iOS 15. This issue has been the biggest headache because my cell service is not that good at home and I usually make and receive calls through Wi-Fi calling. I updated iPhone to iOS 15.1.1 yesterday hoping this would resolve issue but it has not. I have also spent hours on phone with apple and eero support and have not been able to resolve this issue. Again, I never had this issue prior to installing iOS 15 on my devices…
