Joined to find help for my dad. I can only help him with basic tech stuff! He is switching from AT&T to Xfinity cable and Internet. His Internet speed is very very slow, I feel like it is dial up again LOL !!
Instead of renting their gateway he wants to buy a router modem combo. There is no coax connection in the wall. Currently there is a cable coming from the wall to the ethernet port and another cable from the wall in a port labeled “broadband“ to the AT&T box.
Are there any router/modem combo that does not require a coax cable or does he just need to have one installed.

Generally the cable company knows if they every installed service to some house. There system should not allow a self install unless they know there is a cable to hook it to.

You should be able to find a coax cable on the outside of the house. Generally they put them near the power meter. The building code in most locations require the install a grounding block/splice and the simplest way to ground it is to connect to ground bar near the meter.

The cable may or may not still extend into the house if someone removed it. This is why when you have a self install you better have a basic understanding.

The ATT system is likely DSL and not cable. It is delivered over phone wires rather than a coax cable.

You need to find out which devices are compatible with the Xfinity Internet service you are getting.

I suggest you allow Xfinity to install their device and setup the internet service... then you could get your own device and return their device.

he ordered their gateway for self install. I went to do it for him and theirs had a coax cable. I heard about saving money on getting your own instead of renting so tried to find a combo That would match the set up installed end of the wall,but so far they all have coax cable.
Yes, the modem/router needs a coax connection. This is how it comes from the street to and into the wall of the house.

You can purchase your own device.
But for at least the modem half, it really needs to be on their approved list of devices.


"Self install" is great if and only if you KNOW the wiring is correct.

Every ISP I've ever had, cable or fiber, will run whatever cables are needed, from the street to the router. Free, as part of the install.
Mine too. I don’t know who installed it.

He gets manipulated by sales or technicians OFTEN. He’s too trusting when it is something he doesn’t know about. I think I will have them come out and reinstall/correct when I can be there and know what’s going on

He’s had Comcast, Dish satellite, and now the latest ATT. Don’t know who did what and when. Was bundled TV,internet, phone line, but finally ditched the phone . So computer and TV streaming is ridiculously slow.
He just told me ATT cut the coax connecter off when they installed it and he has a coax by the tv for cable. So I’m just have them come out when I can be there. Thanks so much.!!
