Megachip

Better not Update to (ACAJ.2)C0 … had (ACAJ.1)C0 running and everything was half ok - connection is much worse then HomeAV, but at least there is an connection. With (ACAJ.2)C0 I got no connection at all at the same line. Only if I plug them into the same distribution socket, they finding each other.

I've checked. There is even no DHCP Request from that MAC. Are they preconfigured with fixed IP?

What should I do if there is even not webinterface?

Yeah, but seems it was related to preinstalled npcap

What about Windows 11?
