2 modems 1 cable line

[Pyff]

Hello,

My friend has cable internet through Brighthouse (Spectrum), and his modem/router(not sure which one) is way across the house from his PC, connected by an extremely long Ethernet cord.. I want to take my PC to his house for gaming, but I do not have an Ethernet cord that length, and I don't have a network adapter.

My question is: can I take my own modem (gateway) to his house in that room, connect to the coax from the wall, and tether his connection through this 2nd modem, while running modem 1 across the house simultaneously? It seems like I would be able to, but something is telling me cable would be set up to not allow this, extra fees, more money in the providers pocket, etc.

If not, what would be our best option to have the connection down in his room? If it's a multiport modem/gateway across, we would just plug a router to that long ethernet and 2 seperate Ethernets connecting our PCs to the router?

Thank you for any help, comments, or suggestions, I'm a total N 0 0 8.

No, you cannot connect a second modem to his cable line. How, without an ethernet adapter, do you get a connection to your modem, and to the internet? Cat 5/6 cables are cheap, pick up an appropriate length at your local computer store.

I'm pretty sure he just has a gateway and most of the gadgets connect by wifi, but he connects directly with an ethernet cord that comes from the attic, some 3-4 rooms over from the gateway.. could I just connect a router to that ethernet, and tether that connection?

A cable modems only purpose is to talk to the cable company equipment and allow you connect devices via ethernet or maybe wireless. It can not use the coax to connect to another device it will only talk to a cable company.

There is another device sold that will allow you to use coax cable called MoCA but they are kinda expensive. Why don't you use small switch to connect to his long cable and give you more ports.

By switch, do you mean a router,or is there a cheaper piece of hardware? I believe this is my only option. Please let me know what's the cheapest "switch" I can use. Alternatively, he may already be connected to a switch (router) at the other end of the house, and it may be as easy as taking and connecting the router down in his room

Edit: would a switch allow me to just split a connection that's coming from a router?

You need one of these https://www.newegg.com/Product/Product.aspx?Item=N82E16833122005&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Network+-+Switches-_-N82E16833122005&gclid=EAIaIQobChMIzqO_nKis1QIVBIGzCh30iwbSEAQYASABEgKHF_D_BwE&gclsrc=aw.ds

Take the network cable out of your friends computer and plug it into port 1 on the switch, then run a cable from port 2 to your friends computer and port 3 to yours. Now you both will have internet access and can play games together.
