What is the speed of the Ethernet ports on the back on the AMP / Port devices? I know music streaming isn’t bandwidth intensive but in my older Sonos ZP100 I’ve been using these ports to power a simple IP device. The ZP100 ports are 10mbps and I was hoping the newer models were faster - but can’t find it in the documentation. I’m hoping 10/100 - and Gigabit if I’m lucky. Anyone know for sure?
