Mac Studio Ethernet issue with native port

I have been connecting my M1 MacBook Pro to an Ethernet cable using one of the Apple/Belkin USB-C to Gigabit Ethernet Adapters. It works great.

My Mac Ultra Studio showed up yesterday. I unplug the cable from the adapter and into my Studio's native ethernet port: disaster. Fully 50% of a ping's packets are being dropped.

I unplug the ethernet cable from the native port, plug it back into the USB-C adapter I have been using with my MacBook Pro, only this time I plug the USB-C end into one of the Studio's USB-C ports. It works great and no ping packets are being dropped.

What is going on with the native Ethernet port on my Studio? I tried setting the speed manually to 1G but have the same results. Thanks for your help!

It can be related to the speed negotiation. Mac Studio's Ethernet is a 10Gb port. Your router might have a 1Gb one.

In System Preferences, head to Network and select Ethernet. Go to Hardware tab and set the "configure" to manual and selects 1000baset option under speed.
