I have read a lot that manual network settings must be made. I can not confirm. After plugging the power to the vehicle is automatically "Wifi OBDII" recognized by the iPad / iPhone. The IP address, DNS server etc. will automatically switch based also after a short time and are set to go. Perhaps the manufacturer has changed to what the hardware and dongle now has its own DHCP server.
For the money a good buy, especially as you read errors on the shop floor for 1 x / delete that would pay same.
