I have a modem with only two Ethernet ports, and it's not enough for all the devices in my household. I'm considering buying an Ethernet switch, but I've heard about potentially running multiple cables from the modem to the switch for benefits like increased speed. However, I'm not sure if that's a real feature or just a misconception, and if it exists, what it's actually called. Given that we live in a rural area with poor internet service, I'd like to maximize our network speed. Any insights on this before I invest in a switch?

You only need one cable to connect to the switch. Adding more doesn't increase speed and could actually cause problems with the network.
Using multiple cables won’t boost your internet speed; it'll likely complicate things. Just one cable will do the trick, and your switch will be more than adequate for your needs.
If you're looking for a feature related to multiple cables, it's called Link Aggregation, but it requires compatible equipment on both ends. For consumer modems and switches, it's usually not applicable. Better to use just one cable!
Make sure to check if your modem is just a modem or a combo unit. If it’s a true modem, a switch needs to come after a router. Using two cables isn't standard for consumer devices and won't help if your internet speed is below a gigabit.
It's best to run just one cable from your modem to the switch. Connecting both can create a network loop, causing issues like constant power cycling. Keep it simple and stick to one connection!

Exactly, and simplifying your setup will make troubleshooting easier if anything goes wrong.
