# init(ssidPrefix:passphrase:isWEP:)

Creates a new hotspot configuration, identified by an SSID prefix string, for a protected WEP or WPA/WPA2 personal Wi-Fi network.

## Declaration

```swift
init(ssidPrefix SSIDPrefix: String, passphrase: String, isWEP: Bool)
```

## Parameters

- `SSIDPrefix`: A prefix string to match the SSID of a WPA/WPA2 enterprise Wi-Fi network. This value must be between 3 and 32 characters.
- `passphrase`: The network’s passphrase credential: for WPA or WPA2 personal networks, 8-63 characters; for static 64-bit WEP, 10 hexadecimal digits; for static 128-bit WEP, 26 hexadecimal digits.
- `isWEP`: If doc://com.apple.documentation/documentation/Swift/true, the network is WEP Wi-Fi; otherwise it is a WPA or WPA2 personal Wi-Fi network.

## Discussion

Discussion Use this initializer when you want to match a known SSID prefix, but don’t have a full SSID. If the system finds multiple Wi-Fi networks whose SSID string matches the given prefix, it selects the network with the greatest signal strength.
