sometimes it works like this. After numerous changes, do not work. A reset can help.
But you need to know what to set up again

How is your IP01?

keep the ATCOM firmware for the time being and make sue everything work within your LAN. Your LAN setting and devices are more important than the IP01. IP01 is just a new comer to you. It needs to adapt to your environment and use.
Same for your friend.
