Can my current router/modem be used as a router for my new modem?

[tallsheet673]

I have been using my current "all in one" router/modem (there's probably a term for I just don't know it) to stream internet for about 2 years now. Well I've been having trouble with my speed so I called my internet provider and they upped my speed at no cost and sent me a modem that could stream it, in case what I had wasn't sufficient. Well I got it in, expecting to see what I already had, but it was just the modem. It's saying on the instructions that I need a router to attach it to. Now I'm not the most tech savvy so all this could make me look pretty stupid so here's my question: can I use what I currently have as a router and just hook up the modem that they sent me? I should end by saying I did a speed test without doing anything and the numbers that I got match what I should be getting on my plan. Is it worth hooking up what they sent me or should I just leave in what I have? And if it's best to hook up the new one what is the best way to do it with the equipment that I currently have? Preferably without buying anything else

No you cant.You have modem/router all together in one body.You need just router and you don't need modem because ISP supplies to you new modem.

Doubtful. With a combo modem/router, there is no WAN input connector as that whole connection process is handled internally within the component. What you need to do is look at the back side of the modem/router and see how many RJ-45(Ethernet) connectors there are. NOrmally, you get 4 out and 1 in for a total of 5 connectors. or if there is one that has a different color. If this is the case, then you possibly could use it.

But odds are, you will very likely need to get a new router.

You need a router with an Ethernet WAN port that connects to your new modem with an Ethernet cord.

Most routers with an integrated modem (combined modem/routers) do not offer an Ethernet WAN port, and are not compatible with the configuration you require. A very few modem/routers, such as the BT home hub 4 in the UK, offer both Ethernet and ADSL WAN connections (only one of which can be used at a time).

You will probably have to buy a new router with an Ethernet WAN port.

I hope this helps.
