If you would like to change from the access point that the Scanner is set to connect to through wireless LAN to a new access point, please check the "Please read this first" manual included in the ScanSnap iX500 Sansan Edition, and then redo the settings for connecting through wireless LAN.
If the access point that the Scanner is set to connect to through wireless LAN is temporarily unavailable, the Scanner will automatically switch to Direct connection mode.
If that happens, the network written on the (a) area of the sticker on the Scanner will come up on the Wi-Fi connection screen of the procedure for connecting the Sansan Application and the Scanner, so you will still be able to use the scanning function.
