Question

That didn’t work. Any other suggestions! And why doesn’t someone from PreSonus chime in on this? I already tried a different Ethernet cable.

Answer 1

1) PreSonus says this is a user forum, it's not part of PreSonus Support.

2) You are using discontinued products, but you can still get support for your hardware. Open a ticket with Support.

3) For general problems in using PreSonus equipment PreSOnus recommends to join one of the closed/private Facebook groups. This one is specialising in Classic and AI mixers:
