Sets IP address for Soft AP in captive portal. When AutoConnect fails the initial WiFi.begin, it starts the captive portal with the IP address specified this.
Automatically will try to reconnect with the past established access point (BSSID) when the current configured SSID in ESP8266/ESP32 could not be connected.

Sets the offset address of the credential storage area for EEPROM. This value must be between greater than 4 and less than flash sector size. (4096 by SDK)
If the sketch leaves this offset at zero, it will conflict the storage area of credentials with the user sketch owned data. It needs to use the behind of credential area.

Sets gateway address for Soft AP in captive portal. When AutoConnect fails the initial WiFi.begin, it starts the captive portal with the IP address specified this.
Disable the first WiFi.begin() and start the captive portal. If this option is enabled, the module will be in AP_STA mode and the captive portal will be activated regardless of [**AutoConnectConfig::autoRise**](apiconfig.md#autorise) specification.

!!! info "How to specify the value of the menu items"
An menuItems accepts the logical OR of AC_MENUITEM_t type value. For example, to enable only Open SSIDs and HOME items, specify:
However, even if you specify like the above, the AutoConnectAux page items still display on the menu. To remove the AutoConnectAux items, use the [AutoConnectAux::menu](apiaux.md#menu) function.
Sets subnet mask for Soft AP in captive portal. When AutoConnect fails the initial WiFi.begin, it starts the captive portal with the IP address specified this.
Specifies to import the built-in OTA update class into the sketch. When this option is enabled, an **Update** item will appear in the AutoConnect menu, and the OTA update via Web browser will be automatically embedded to the Sketch.

Specify the timeout value of the captive portal in [ms] units. It is valid when the station is not connected and does not time out if the station is connected to the ESP module in SoftAP mode (i.e. Attempting WiFi connection with the portal function). If 0, the captive portal will not be timed-out.
Specify whether to continue the portal function even if the captive portal timed out. If the true, when a timeout occurs, the [**AutoConnect::begin**](api.md#begin) function is exited with returns false, but the portal facility remains alive. So SoftAP remains alive and you can invoke AutoConnect while continuing sketch execution. The default is false.

With the **retainPortal**, even if AutoConnect::begin in the setup() is timed out, you can execute the sketch and the portal function as a WiFi connection attempt by calling AutoConnect::handleClient in the loop().
!!! info "All unresolved addresses redirects to /_ac"
If you enable the **retainPortal** option, **all unresolved URIs will be redirected to `SoftAPIP/_ac`**. It happens frequently as client devices repeat captive portal probes in particular. To avoid this, you need to exit from the WiFi connection Apps on your device once.
