Hello,
I am using an M1 iMac that is connected to a TP Link switch (wired). Whenever the iMac is in standby the network port on the switch starts toggling between 100mbps and 1gbps. Whenever the iMac is in use it is working fine with 1gbps. Is there any reason the network speed changes while in standby? I am receiving mails from my monitoring software that the switch port seems to be faulty, because it falls back to lower speeds.
Thank you!
What model TPLink switch? Are you using a USB-C ethernet adapter or the built-in ethernet adapter in the iMac power brick? If USB-C, what make/model USB-C adapter?
Hello Bigwaff,
the switch is a TP-Link SG3452P managed switch. The iMac is connected using the build-in ethernet adapter. There is no other device on this port.
i am using 10 wired devices, none of them is showing this behaviour.
I guess a faulty network cable is not the issue when the connection is stable at 1gbps when the iMac is in use.
