How Apple devices decide which known wireless networks to auto-join

Known wireless networks are networks that your device has joined before or that are installed on your device as managed networks, such as through a device-management service. To determine which known wireless networks to automatically join, your device prioritises connections in this order: from highest priority to lowest priority.

1. Most preferred network

Known wireless networks are scored based on your actions. When you manually connect to a network, its score increases. When you manually disconnect from a network, its score decreases. The network with the highest score is the most preferred.

2. Private network

Private wireless networks are those set up in homes and offices, and they can include a Personal Hotspot. The most recently joined network has highest priority.

3. Public network

Public wireless networks are designed for general access in public places such as hotels, airports and coffee shops, and they can include Passpoint (Hotspot 2.0) and EAP-SIM networks. Known public networks can also include managed networks set up by your wireless network provider and its partners.

4. Configuration method

Private wireless networks configured using a device-management service are preferred over manually joined networks.

5. Highest supported Wi-Fi standard

Highest to lowest priority:

• Wi-Fi 7 networks

• Wi-Fi 6E and Wi-Fi 6 networks

• Wi-Fi 5 networks

• and so on

6. Frequency band

Highest to lowest priority:

• 6 GHz

• 5 GHz

• 5 GHz (DFS)

• 2.4 GHz

7. Security

Highest to lowest priority:

• WPA Enterprise (any version)

• WPA Personal (any version)

• WEP (any version)

• An open (unsecured) wireless network that wasn't manually joined in the last two weeks isn't auto-joined, unless it was installed on the device as a managed network within the last 24 hours.

8. Signal strength

The wireless network with the strongest signal has highest priority. Find out about signal strength and RSSI.
