(How to Check VXDIAG device IP address?)
If IP is not correct, need to reset firmware. You can follow this instruction to do.
If still no device after firmware reset, need to connect device to the car or power supply, after the wifi light flashes, and hear a beep, use phone to search wifi if can find device wifi name like “DOIP-VCI***”. If yes, open local internet connection, find the device wifi, click it to connect, wifi password is 12345678. Check vx manager again if can find device information.
If no wifi light flashes, no beep, cannot find wifi name of device, probably damaged, need to repair.
If all the above not working, contact vxdiagshop.com customer service for technical help.
