Mostly an aside: My brother lives in rural podunk USA and he has a fiber optic connection which his ISP says gives him 500 mbps (I live in a fairly urban location but can't get fiber)
Background: His ISP says he has a 500 mbps connection which, without having seen his setup in a number of years, I'm sure there is a modem connected to a router (or maybe a combination modem router), that, connects to a television (that is the main user of the 500 mbps, iiuc), a Mac, an ObiHai, and, via WiFi, to two security cameras. There is one free Ethernet port on the router (or router modem), and I'm sure those ports must be 10/100/1000 "autoselect" type ports. The WiFi "connection" to the security cameras is unreliable, and he would like to hardwire the security cams to the network (I don't know whether he views them with the TV or with the Mac, or both, and I'm sure it doesn't matter). I'm about to recommend that he get a 10/100 5 port Ethernet switch to connect to the two cameras and then a short cat5 (or better) Ethernet cable to connect from the switch to the router. I'm abouit 99.9% sure that using such a switch will not slow down any other parts of his network, but I don't want to mislead him. (I do recognize that a 10/100/1000 switch might give him flexibility to use more faster than 100 mbps devices in the future, but he could also connect such a new device to the router and move a slower device (e.g., the ObiHai or the Mac) to the switch.) Am I missing anything?
