Why might a Mac use Wi-Fi while Ethernet is connected?

A Mac with both Wi-Fi and Ethernet available may not use the connection you expected. Network service order helps establish which ordinary service the computer tries first. This is especially useful for a desk setup where a dock provides the preferred wired connection. Check the dock's network service and its connection status before changing priorities. An attached cable is not proof that the service has a usable address or route. Inspect the far-end port and compare a known-working cable if the wired service appears disconnected.

How can the Steam Link overlay help diagnose stutter?

Increasing Steam Link's bandwidth limit can sharpen a stream when the path has spare capacity, but it can make an unstable connection work harder. First determine whether the freeze coincides with a network-timing problem or another stage of the streaming process. Choose a familiar game section with predictable movement. Keep resolution, frame rate and host graphics settings unchanged during the first comparison. Testing a quiet menu and then a complex action scene creates a misleading before-and-after result.

Is SMB Multichannel the same as link aggregation?

Two Ethernet cables connected to a NAS can mean several different configurations. Link aggregation usually helps distribute traffic across links, while SMB Multichannel lets a supported SMB session use multiple connections. They are not interchangeable buttons for doubling a laptop's file-copy speed. Do you want one laptop to copy faster, or several family members to access the NAS simultaneously? That distinction determines which feature deserves investigation. An aggregate server-capacity improvement can be useful even if one individual transfer stays near the speed of a single link.

Why does an Ethernet connection negotiate only 100 Mbps?

If Windows reports a 100 Mbps Ethernet connection when you expect gigabit or faster, inspect the local wired path first. An internet speed test cannot make that local link negotiate at a higher rate. Identify whether Ethernet comes from the computer, a USB adapter or a dock. Check its documented rate and the far-end router or switch port. Some equipment has mixed-rate interfaces, so the fastest specification on the box may not describe the socket in use.
