My iPhone 14 Pro Max keeps dropping and reconnecting to wifi every few seconds. This happened right after I updated to 16.1.

Since updating to iOS 16.1, neither my iPhone 11 Pro nor my iPhone SE (2) would connect to my Wi-Fi. I tried the suggestion just above. I also toggled the phones’ Wi-Fi, forgot and rejoined my network, and reset all network settings. Nothing worked, not even for a few seconds.

On a whim, I checked my TP-Link Deco mesh routers. A firmware update was available, so I downloaded and installed it. Once the routers were back online, both phones magically connected to the network.
