Ethernet dilemma

Hello,

My internet service was setup in a room upstairs with a phone jack. I currently have my computer downstairs and I have a phone jack down here.

Does service work if I move my modem downstairs as internet is connected to the whole home? Another thing bugging me is the space I have downstairs is limited and to bring my modem along with my ata phone adapter and primary phone is bothersome.

As I am limited to wifi only at the moment, is there any other possible solution? I really don't want to use wifi anymore. Is it possible to utilize my downstairs jack without having to move my modem?

Thank you.

Is your Internet running off the phone jack making it DSL? If so, then yes, you can move the DSL modem. If it's cable/fiber and provides the phone service to your home, then you'll need to move that COAX to that room if it's a cable modem. If it's fiber, that's more complicated.

Forgot to mention I'm using DSL. The thing is I have tons of stuff to move along with my router, ata, primary phone..

The phone jack uses an rj-11 so I can't connect the rj-45 ethernet cable, is there a rj-11 to rj-45 cable?

Wait, what?

Why do you need to move your phone if you move the DSL modem? You simply keep the phone connected to the phone jack in the wall where it was originally (or in the odd case that your DSL modem had an internal splitter which gave a phone-in, and phone-out where-in you have a phone wire connecting the phone jack in the wall to the DSL modem, and then another phone wire connecting from the DSL modem to your phone, you would now simply just connect the primary phone to the phone jack in the wall (and take the DSL modem downstairs)).

There is no such thing as a RJ11 to RJ45, as there are not enough wires in a RJ11. There are some specialized cables which use the 4 twisted pairs in a CAT5/CAT6 cable potentially having one or more ends using a RJ45 connector and 1-4 RJ11 connections at the other side, but you can't use these for connecting computer/data networks (you see these used a lot of times in older non-IP based phones which had multiple phone lines (i.e. what businesses typically used at main call points, and the mechanism of many a joke where-in the person using the phone switches to the wrong line and tells their boss they love them or something when they thought they were talking to their significant other on the other line).

Given how confused you seem to be, I suggest watching this quick youtube video explaining phone wiring in homes:

Isn't there some DSL filter for analog phones? If the mode has a connector for a phone, then it probably acts as such filter. When you move the telephone to different phone jack, a discrete filter might be necessary. They were small, cheap, and passive.

Using voip.... thought the ATA would give it away. I know there are rj-45 outlets on the wall (would need rewiring), but anything along the adapter or hub from wall to computer?

Used to get a 4 pack of them from AT&T with the DSL modem kit

Very interesting setup you have. You have RJ-45 outlets on the wall? You sure those aren't regular phone jacks? Does a regular network cable plug into that wall jack? It is entirely possible that it's RJ45 but its only wired for phone. Regular phone jack will fit fine into an RJ-45 at least the ones I've used past decade. Either way, I'd get a networking friend on site. Your house could very well be Ethernet wired up. Only way to find out is get someone on site to find out and move the equipment for you.

No RJ-45 on walls :) I'd be in bliss if that were the case lol.

I think he means look behind the wall plate. It is possible installer used ethernet cable instead of phone cable and just used a pair of the four pairs for the phone jack.
