Gigabit port switch details
Yes, you can connect a gigabit port switch directly to the modem without a router.
Yes, but it wouldn't really work because you'd only be able to link one device to the internet at once if I'm understanding it correctly: https://www.quora.com/Can-I-connect-the-...the-router
If it's just a modem and not a gateway (modem/router package), the first device to request an IP address will receive the public IP assigned by the modem, and the remaining devices won't gain internet access.
It depends on how the switch is configured. If it supports multiple ports, you can still connect just one port even if there are five available.
Yes, you're correct. If you ever switch off the modem, detach the switch from the power adapter, then restart the modem and connect it to the internet, reconnect the switch afterward. Some switches may panic when the modem is turned off and then turned back on. To avoid this, connect the switch to the modem via the Ethernet port 1 on both devices. If you later add a router, set port 1 from the modem to WLAN on the router and port 1 on the router to port 1 on the switch.
No, you cannot as you will only be able to use a single device at a time on a pure modem. The first device to ask for an IP will get the 1 available public IP and that's it. A switch doesn't have specific uplink ports either and there is no need to connect to the first port on any device. There also isn't anything that will "panic" a switch when things are turned off and on, that's nonsense.
If you agree, it seems likely true. I’ve been doing this for ten years, but probably you were just imagining things. Ten years of imagining on an old modem with just one Ethernet port—definitely not possible. Your modem won’t get a static IP unless you originally purchased it, so it will use a dynamic one. Also, you seem to be mixing up concepts; the local network and the internet are different things. Remember, a pure modem hasn’t been around for many years—actually, all modern modems are routers. That’s probably the right answer, and thanks for the helpful comment!
Modem devices remain clearly distinct and still widely used. Companies like Motorola continue producing them, along with many others. For instance, the SB6183 modem is a common example. I didn’t mention static IP settings; what I meant was that the first modem to request an IP would receive a public address, while others would overlook it. Modems don’t function as routers—they’re separate units. A gateway combines a modem, router, switch, and wireless AP into one device.
