Сonnect Coax out to RJ45 in

[jurciksss]

Hi guy's,I have a cable internet with coaxial output and ISP provided modem router with coax input.
Now I want to replace that router with my own but the problem is - my router doe's not have coax input,RJ45 only.
My question is : what should I use to connect Coax out to RJ45 in ?

If your personal modem don't have a coax in port, then it's not a cable modem. Coax to ethernet adapters are expensive and not worth the price. If you don't want to use the ISP's supplied modem, then you are better off buying a new modem like the Motorola Surfboard.

If you are just trying to use a personal router, then that's easy. Use the supplied modem from your ISP and connect your router with a ethernet cable from the modem. If your ISP gave you a modem/router combo and you don't want to use the router part, you don't have to. Or you can just bring it back and tell them you want a modem instead of the combo. They will replace it for you.

This is Technicolor TC7200U router. This router has ISP customised OS on board , I can't even set static IP on this device or change username which is the same for all my ISP customers that using this router , that's the reason I want to replace it.

thank's for your answer , this is modem/router and it's almost useless in terms of changing some settings , set download/upload limits , set static IP e.t.c.
I have one old Scientific Atlanta EPC2203 cable modem , probably have to use this . Just not sure about the speed , I have 240mb/sec Internet, if this modem are capable to work with this speed.

the old router is set to have a max speed of 10/100 so to slow for your need the thing i could suggest it to get a router plug in one of the isp lan output and then to yor new router input you will be able to set your own router for static in it but not the isp one or contact them to have a static ip wthat will cost more or ask them to have a modem only and from that modem go to your new router so the only mac address modem will see is your router one.

If the TC7200U has a single RJ45 on the back then this is a plain modem and you can just plug your favorite router downstream from it, like so:

TC7200U ---> Router ---> Clients.

The TC7200U does no processing, no NAT. There is nothing for you to configure here.

HOWEVER, if the TC7200U has 4 RJ45 on the back, this means it's a GATEWAY and it does lots of stuff, sounds like what you may not like. Your options are: Replace this with your own CABLE MODEM/ROUTER as suggested, or if you already have a favorite non-cable router in mind, ask the ISP to give you a plain modem instead of a gateway.

It is a modem/router , here is a manual for it: http://setuprouter.com/router/technicolor/tc7200-u/manual-1685.pdf , however some of settings are not available for me(it's locked or removed by ISP), for example I don't have USB configuration.

contact them and see what they could do to help you on this .since the modem belong to them and the have a encrypted password .

Easiest thing to do is return it to your ISP and tell them you want a regular modem and not the gateway or get your own. This one is on sale and it will lower your bill since they can't charge you rental fees every month. http://www.newegg.com/Product/Product.aspx?Item=N82E16825390001
