Joining Apple devices to Wi-Fi networks
Users can configure Apple devices to join available Wi-Fi networks automatically. For Wi-Fi networks that require login credentials or other information, users can quickly access Wi-Fi settings and enter the credentials or use a configuration profile that contains the network name and login credentials. Any app on the device can access the networks seamlessly. With low power, persistent Wi-Fi connectivity, apps can use Wi-Fi networks to deliver push notifications. For example, by using configuration profiles that are pushed to a device through a mobile device management (MDM) solution, you can configure settings for wireless networks, security, proxy, Fastlane, app whitelisting and authentication.
Authentication and encryption support
Apple devices support various authentication and encryption methods, including WPA, WPA2 Enterprise and WPA3 standards for encryption, and PSK and enterprise 802.1X authentication. See how iOS decides which wireless network to auto-join. With support for 802.1X, Apple devices can be integrated into a broad range of RADIUS authentication environments. Apple devices support 802.1X wireless authentication protocols, including:
PEAPv0 (EAP-MSCHAPv2, the most common form of PEAP)
PEAPv1 (EAP-GTC, less common and created by Cisco)
You can also use WPA/WPA2 Enterprise authentication at the login window of macOS, so the user logs in to authenticate to the network and the macOS Setup Assistant supports 802.1X authentication with username and password credentials using TTLS or PEAP. See the Apple Support article: Use Login Window Mode for 802.1X authentication to a network
Important: Apple devices must have access to your wireless network and Internet services for setup and configuration. You may need to configure your web proxy or firewall ports to allow all network traffic from Apple devices to Apple’s network 18.104.22.168/8. If Apple devices are still unable to access Apple activation servers, iCloud or the App Store, see the Apple Support articles Unable to use Apple Push Notification service (APNs), macOS wireless roaming for enterprise customers and Use Apple products on enterprise networks.
