There are several known compatibility issues and connectivity problems reported between iOS 18.3.2 and certain routers or network devices. Here are some detailed insights:
1. General Wi-Fi Connectivity Issues: Many users have reported frequent Wi-Fi disconnections and connectivity problems with iOS 18.3.2. These issues seem to be related to the operating system itself rather than specific router models, as other devices like Macs and Apple TVs do not experience the same problems[1][7].
2. Private Wi-Fi Address Feature: Disabling the Private Wi-Fi Address feature has been suggested as a potential fix for some users experiencing connectivity issues. This feature, while beneficial for privacy, can sometimes interfere with network connections, especially in environments with multiple devices or complex network setups[3][7].
3. Mesh Networks: Users with mesh networks, such as those using TP-Link Deco devices, have reported issues with maintaining stable connections and experiencing choppy audio on local network streams. This seems to be related to how iOS 18.3.1 handles network roaming and node switching[9].
4. Specific Router Models: There have been reports of issues with certain router models, such as the Netgear RAX30, where iPhones running iOS 18.1.1 would disconnect shortly after connecting. However, these issues might not be specific to iOS 18.3.2 but rather a broader compatibility problem with iOS 18[3].
5. General Troubleshooting Steps: To address these issues, users can try basic troubleshooting steps like restarting their router, updating router firmware, forgetting and reconnecting to Wi-Fi networks, and resetting network settings on their iPhone[2][7]. If problems persist, waiting for an update from Apple might be necessary.
In summary, while there are no specific router models universally identified as incompatible with iOS 18.3.2, the operating system itself appears to be the primary source of connectivity issues. Users may need to apply general troubleshooting methods or wait for future updates to resolve these problems.
