Can WiFi Shield go into adhoc (infrastructure) mode?

I've done this with an ESP8266 using the Captive Portal example. It starts as an adhoc network, once you join it lists the available SSID's on it's web page. Then you type in the SSID and Password. It keeps the ad-hoc network up at 10.0.0.1 but redirects all calls to your infrastructure network over the IP it obtains when it joins that network. Black magic - and well worth time to look at:

github.com

esp8266/Arduino/blob/master/libraries/DNSServer/examples/CaptivePortalAdvanced/CaptivePortalAdvanced.ino

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <DNSServer.h>
#include <ESP8266mDNS.h>
#include <EEPROM.h>

/*
   This example serves a "hello world" on a WLAN and a SoftAP at the same time.
   The SoftAP allow you to configure WLAN parameters at run time. They are not setup in the sketch but saved on EEPROM.

   Connect your computer or cell phone to wifi network ESP_ap with password 12345678. A popup may appear and it allow you to go to WLAN config. If it does not then navigate to http://192.168.4.1/wifi and config it there.
   Then wait for the module to connect to your wifi and take note of the WLAN IP it got. Then you can disconnect from ESP_ap and return to your regular WLAN.

   Now the ESP8266 is in your network. You can reach it through http://192.168.x.x/ (the IP you took note of) or maybe at http://esp8266.local too.

   This is a captive portal because through the softAP it will redirect any http request to http://192.168.4.1/

/* Set these to your desired softAP credentials. They are not configurable at runtime */
