Home Internet - I do not recognize a device on my network

I encountered the MAC randomization issue with my iPhone 12 pro and my iPad Pro both where I could connect to the T-Mobile Nokia router and the wireless would show full connectivity on the WLAN but no internet connectivity. This appeared to be random but upon deeper investigation I discovered articles that explain in more detail how the MAC randomization works. Apparently iOS 14 generates a new random MAC address every 24 hours. (per macaddress.io FAQs) It is a very frustrating issue. My solution, which resolved the behavior as far as I can tell now, was to disable the feature and NOT use it on my local wireless LAN. The improvement in behavior was pretty much immediate after rejoining the wireless network. I also noticed in the Nokia router it has 128 devices per radio. If there is a table that builds persistent then I was maybe hitting the ceiling and that would account for why the problem became worse over time? I cannot say for sure about that but it is clear to me when I disabled the feature in the iOS 14 device my wireless network sessions became rock solid. I also discovered Android, Linux and Microsoft each also support MAC randomization. For Apple iOS 14 that security feature to prevent tracking is enabled by default. For anyone connecting an iOS 14 device onto a LAN where the MAC authorization is used this would have repercussions especially if the MAC is randomized every 24 hours as the FAQs suggest. “However, since a specification on MAC address randomization does not yet exist, iOS, Windows, and Linux, all implemented their own variants of MAC address randomization.” (per macaddress.io) I hope this helps to explain some of the frustrating behavior with iOS 14 devices.
