While i establish connection to my BMW m4 f83 with ista-d 3.51.31 & istap 3.56.4, the clone icoma2 some how just dis-connected the Ethernet ip and then after a few seconds it connect again, it happens while i'm diagnosing the f83. All this time the car engine was running. with voltage kl15 at 13.21 & terminal30 at 13.21 volts

all my firewalls are off, no antivirus is installed. the BMW m4 f83 has a flexray bus on it, could it be too fast for the clone icoma2 to handle?
my icoma2 has the latest firmware update on it. ICOM-BootImage-01-24-00.bin /ICOM-ApplicationImage-01-38-01.bin

The present i-level of the f83 is F020-14-07-505 is the factory & actual i-level of the f83.

I intent to program a new ACSM Module bought from the dealership but my icoma2 clone is dropping off ethernet connection then it connects, then off again and on,

May icom clone is overheating and reboots because of that?

Try connecting to your ICOM and do SOFT RESET
Try flushing it with other firmware
Check Inside of an icom see if cooling pad is installed
Check your car voltage
