Router hookup to modem question

The round connector on the back of her modem is for a coax cable connection for an internet source - like a cable company or the feed from her satellite box. A modem delivers an internet signal and shares it with a computer or a network connected to computers. The modem should also have a network socket (maybe more than one) that will be used to feed the signal into a router (either wired or wireless) to distribute internet to a network or just one PC through a network cable from the modem to the PC. The phone like connector she sees on her router is a network connection - larger than the plug or socket used for a telephone. There has got to be more than the "round connector" on that modem. Or she is looking at a satellite box that would only have coax connectors - in and out - and that then needs a modem to connect to via coax and then out to the pc or router via network cable. If all that is there is the coax connector(s) she does not have a modem.

It is highly unlikely anyone has a phone modem any longer - while it would still work on a phone dialup connection, it would work VERY slowly.

Just a model number of the modem will do, there has to be info online.

I know pics would help but I don't have them. She's recently had back surgery
, but got an iPad from her sister for Xmas. She wanted to use Kindle on it & nephew downloaded a book for her but when she got home couldn't read it because she didn't have wifi which I told her she needed router for. Maybe I can go look at it this week. Told her to take pic of hookups with her to store to see about correct cord for extension or replacement . Maybe I can help her get it figured out with your suggestions. All ideas are appreciated!

Cable/satellite modems have 3 types of ports. A round female F for the incoming signal from the satellite, a round male connector for the DC power, and one RJ-45 jack (looks like a telephone jack, but larger) for the outgoing signal to the router. If its a combination modem and router, there will be multiple RJ-45 jacks.

Are you sure the cable with the "phone line jack" is not an Ethernet cable...and the round cable sounds like the power cable, or maybe that could just be an coax cable.

Yep, a picture is worth a thousand words..

In my experience, and I have had satellite internet, a "round" cable (just like the old TV cable) is used to connect the dish to the satellite modem. The modem is then connected to the LAN connection on a standard router using standard RJ45 jacks and Cat 6 cable.

Make and model# goes a very long way to support.

She might be mixing up her equipment and plug types. She might be looking at the cable plug on the modem, thinking it is the router plug. If she can get access to the internet somewhere else, viewing some youtube videos on how to hookup may help her figure out which plug is which.

I looked quickly to see if I can find any Satellite receivers that have weird plugs. They all appeared to have the standard RJ45 Ethernet port. Pictures, model numbers, etc, would help.

Sounds to me like she has real old equipment......Most modern modems have built in wireless as well as ports for wired connections.
