SoHo AP on/off switch

On the SoHo Firmware 6.3. On the Dashboard there is a On/OFF switch for the AP

what does this do? If it Turns the AP off …how do I get back to the router from my iPad

The dashboard On/OFF switch is use to turn on or turn off the WIFI AP.

If you turn off the WIFI AP, no WIFI AP will run for the SOHO device, thus you need to connect the SOHO device using Ethernet connection via LAN interface for the device.
