    * Your STA can connect to the SoftAP as a client, get the DHCP IP, run ping, and run web browser to connect to Web Server
    * of SoftAP. It will allow you to re-connect / redirect to another AP in infrastructure mode.
    * The reason this demo sits here is simply A) borrow DHCP server; B) borrow HTTP server.
    *
    * Before starting up as SoftAP, prescan (MY_DEFAULT_CHANNEL_LIST_PRESCAN) will be executed.
    * For SoftAP, default channel is assigned as MY_DEFAULT_CHANNEL_LIST i.e single channel 6. This means SoftAP
    * will start up in channel 6.
    * When scan option is selected in EZConfig web browser in SoftAP mode, the prescan results will be displayed.
    * Repeated selection of this scan option will always display the prescan results. From this prescan list, the user can select
    * an AP to be redirected to.
    * When redirected to another AP, the channel list will change to allow more channel listings in infrastructure mode,
    * i.e all channels MY_DEFAULT_CHANNEL_LIST_POSTSCAN. This means AP will scan MY_DEFAULT_CHANNEL_LIST_POSTSCAN
    * channel list.
    *
    * Also note that this is a very simplified SoftAP. So its function is limited as , A) no routing supported; B) only 1 client allowed
    * at a time.  And security wise currently it supports both open mode and WEP security.
    *
    * SoftAP's default IP is 192.168.1.3 and its Network Mask is 255.255.0.0
    * SoftAP on certain setups with IP adress 192.168.1.1 has problem with DHCP client assigning new IP address on redirection.
    * 192.168.1.1 is a common IP address with most APs. This is still under investigation.
    * For now, assign this as 192.168.1.3
