rj11 to rj45 using telephone cable lead

hi guys,

i recently bought a new router called TP-Link. However, when i looked at the back of the router - it has an rj45. The problem is that the previous tp-link router i had has an rj11 which easily fits my telephone line for my broadband. my broadband runs from an rj11 ports from both end. this router has rj45 which means i need to convert my telephone line (for broadband) one end to rj45 while the other end is rj11.

will it work like that if i convert one end of my telephone line to rj45 while the other end which connects to my telephone line remains rj11?


i need to buy a modem like this - https://drive.google.com/file/d/0B9vLczGAxxUMWmNLOXVTZVQ5Ylk/view?usp=sharing

Most assuredly not. Modern network cabling standards have iteratively improved, but the basics have been around for 30+ years, and the RJ-45 jack is the standard for Ethernet networking (even base-2 coax has fallen by the wayside many years ago.)

If your broadband is delivered via RJ-11, it is not using Ethernet as a transport, so your router wouldn't know what to do with the signal if it is "just" a router. Some routers have integrated DSL modems, while others are specially supplied equipment from the provider, but regardless, you have to take the signaling from the provider and convert it into Ethernet...even if that happens in the same box. By far the most common is DSL and the transport is PPPoE or PPPoA, but that still means a standard Ethernet router is not sufficient.

You really need to know how your broadband is provided and either lease or purchase supported equipment to make this work. The RJ-11/RJ-45 mismatch is just a symptom. The underlying issues are much bigger.

thanks cliff.

i do understand how my network works. I am using ADSL from my ISP.

The problem here as i mentioned before is trying to connect this tp-link router which has an rj45 port directly to my DSL connection which is rj11.

So i am wondering whether to have my telephone line built (one end of rj45 and the other end that connects to dsl of rj11)


buy a modem?

i know the telephone cable can be configured one end to rj45 and the other to rj11 - but will it work directly to my tp-link router? if it is and no problem then i dont need to buy a modem to avoid power consumption.

An Ethernet router doesn't "speak" DSL. Even if you built such a cables your router would not establish a broadband connection. You need a DSL modem.

If your TP-Link router supports ADSL, it will have an RJ11 marked ADSL.  Otherwise it doesn't and you will need a separate modem.  http://www.tp-link.us/products/list-15.html
