help with modem router cable


hello, i just bought a netgear dg834 modem router so that i can (finally) connect to the internet through linux, but one of the cables (RJ?) isnt long enough to reach the filter in the phone socket.

i was wondering if i could make a straight swap of this short cable, for a longer cable i had with my old usb modem? is there a risk that the cables could be different spec and so damage the router?

Ok not familiar with Telephone systems over seas but I assume it is a 4 conductor cable used by other phones in the house. If so then a longer one of the same type would be fine. In the US most home phones use the RJ-12 cables. Then on Network side one uses RJ-45s. Now one thing confuses me. I am guessing this is a DSL type connection. Usually the modem is directly connected to the wall outlet. Any other device like a phone, fax, answering machine, and other use the filter between the wall connection and device. Just wondering since this is the way it is done here.

brian, yes the new cable has 4 copper/metal connections on the connector, which is identical in size/shape to the old cable.

i think we've got an ADSL connection.

the modem connects to a telephone filter via the RJ cable, then the filter is plugged into the telephone socket in the wall.

there is a 'female' connector (think thats the right terminology) on the filter to plug other devices into.

I see no problem getting a longer cable with the same ends. Its just the filter on the modem is throwing me. Here we plug the modem directly in and use the filters on other devices.

No. There is no "risk".
Your telephone / DSL socket is too far away to connect to your modem/router. So you can easily add an extension cord that has compatible connectors ("If it fits, it's probably OK"). If the extension is "too long" it will just not work, or be slower than it could be. Nothing will be damaged. How do you think the wires from BT (or your other provider) get to your house? There are a load of "extensions", over and under the streets between your house and the telephone exchange / ISP.

So, add the extension / use a longer cable, and see if it works.

"My light is too far away from the mains socket. Is it safe to use an extension cord, or will my light be damaged?". You can possibly answer this yourself, but maybe not

Get a grip on life, and please learn to use your keyboard: "i was wondering if i" => "I was wondering if I". Spot the difference?

Sheesh. What is the world coming to? People are too fearful to plug one extension cord into the next?

tredegar, there is no need to be rude, however i seem to remember you having answered questions patiently in the past, so i will put this down to you having a bad day.

the reason i asked for help was because im not familiar with the cabling and wanted to ask the LQ community first just incase there was a risk of damage to the new hardware.

Brian, i did swap the cable and the router is working fine, thanks.
