I've just set up a deco mesh network in our home. Before, my PC and my dad's computer were linked via Ethernet to the router using separate cables. Now, with the new deco units, I'm running out of available ports in the workspace for all my devices. I was considering using one switch from a deco unit to connect both PCs, wondering if this would create any bottlenecks when the cable connects the switch to the router. We have gigabit internet and use CAT6a for all connections, with all ports supporting gigabit speeds. Appreciate your guidance.
A switch is possible, but the uplink speed will be divided among the devices. This shouldn't be obvious unless the connection uses WiFi via the Deco, which will naturally be slower than gigabit.
Well... whether it's behind a switch or directly on the router, if the ISP's uplink isn't over gigabit, it won't matter at all.
Internet connection is stable, though local traffic might be present...
A simple Gigabit switch is more than sufficient for the task. In theory, you could rewire a Cat6 cable using two connectors at each end—each carrying four wires—and use two 100 Mb connections over a single eight-conductor cable. But in 2023, no one wants to go that far with Fast Ethernet speeds.
In reality, the current issue will resolve once you adjust the main setting. Just turn that little control and connect it, it should work!
