Didn’t know where else to ask this so figured this would be the best place. What exactly is Coax used for? I ask because i’m self installing new Xfinity internet and the instructions say to plug in the Coax and what not. What exactly does that do? It that how the gateway actually gets internet or does it simply “distribute” the internet to other parts of the house?
Truly could not find a good answer on google so just wondering if it’s truly necessary or does simply plugging the gateway in work?
Mind you im not getting cable or anything like that. It’s simply wifi and that’s it. Thanks in advance.
Edit (Solved): To make things short, I plugged my Xfi gateway into these coax outlets in my house but they weren’t working. So, I tried plugging my Gateway directly into the main line outside and it works just fine meaning either the two ports I tried both happen to not work or the wires that take the connection to the rest of the house don’t work. So i’m gonna attempt to connect it in a port upstairs and see if it works just to confirm either possibility. But the problem is largely resolved. Thanks to the legends in the replies for the help!

Former Xfinity employee here: you have one main coax line that goes into your home and it normally ends in your utility room. Also in the room will be other coax lines. These are connected to the coax outlets inside your house. Assuming you have just the gateway, you need to connect the line coming from outside to the line that does to the outlet you want to use. Then you connect another coax from the outlet to the back of the gateway.
If you are going to use multiple coax outlets throughout your house (i.e. you have the gateway and then maybe a cable box in another room) you would take the line from outside and connect into the “input” port of a 2-way splitter, then connect the lines going to the two outlets you want to use to the two “output” ports on the splitter.
