GeekN0m0r3:
首发入的澳大利亚版 Air, 拿到手就有 Wi-Fi 问题. 没法在两个路由器之间切换. 更新到了 iOS 26.0.1, 问题还在, 换了一台机器, 问题还在. 感觉问题是新的 N1 芯片造成的.
具体表现为可以正常连接卧室里的 AP 路由器, 但是走到客厅里, 无法自动切换到主路由器. 并且 Wi-Fi 页面会不断的自动刷新, 即使能看到想连接的 Wi-Fi, 也没法连接成功. 而且蓝牙也非常不稳定, 应该是蓝牙和 Wi-Fi 服务都在抽风, 不断的自动重启.
安装了官方的 Wi-Fi diagnostic profile, 能看到手机无法正确识别 Wi-Fi 的设置 ( https://cln.sh/3VdJmh4g). iPad 里能看到 iPad 可以正常识别 multiple AP 的设置 ( https://cln.sh/wDvBpS01). 也不知道系统是怎么识别的, 但应该能说明手机 Wi-Fi 确实不太正常.
连接到 MacBook 后记录了下 log.

希望 iOS 26.0.2 能修复这个问题吧... 不知道除了升级 beta 系统 和 给厨子发邮件之外还有没有别的办法把这个 log 传给苹果工程师.
