## Features

- About this item
- .
- MOVE YOUR WIFI ROUTER: Connects your ADSL Modem to a Microfilter. Can be used with a plug in filter or directly into an Openreach MK2, MK3 MK4 RJ11/RJ45 combination type Phone & DATA Wall Socket. Higher Quality Round Twisted Pair cable with Gold Plated pins gives improved connection speeds when compared to the standard flat non twisted pair phone cables supplied with many routers. We supply FREE Cable clips allowing you to tack any lengths of 5 Metres or above     GOOD POSITIONING IS KEY: Most suppliers are only interested in their service being in your property even if it has to be at your front door wasting half of its useful coverage. Moving your BT Home hub 4 5 or 6 for example, to a more central location in your home will boost the Wi-Fi strength to more locations. Many customers are aware of this but most will use the wrong type of replacement cable resulting in cancelling most of the performance benefits that they could have achieved     PRESERVE YOUR CONNECTION: Adding any additional wire to your modem supply will weaken your signal very slightly with the correct cable but drastically with the incorrect type. No cable can increase your speed unless it is replacing an inferior one of similar length. However, relocating your Smart Hub for a stronger broadcast where the unit will actually be used, quickly outweighs the minimal losses of a good quality cable, resulting in much better overall wireless performance     NO RJ45 TO RJ11 CABLE NECESSARY: Please note that your BT Openreach Master with VDSL Interstitial faceplate was designed to accept both the bigger RJ45 as well as these smaller RJ11 plugs in the same DATA socket . The wall socket may appear to be too big at first but this cable will definitely click into position once offered up correctly. Many people make the mistake of assuming that they need to find a cable with both an RJ45 and RJ11 connectors but this is simply not true

### ⭐⭐⭐⭐⭐ 







  
  
    It works!
  

*by R***B on Reviewed in the United Kingdom on 19 May 2020*

We are moving from Virgin to Sky, but when the engineer came to install the new phone socket, he decided to put it in the hall. All good, but all the kit is in the living room! And of course, the cable supplied is the shortest one possible!There are plenty of these long cables available, and it was more or less a random choice as to which one I went for. I massively overestimated the length I needed and bought 50 feet when I only needed 20, but hey ho. Cable clips were supplied so it was no effort to tack it along the skirting board to a central living room position. Plugged it all in and...it worked!I have had no problems with speed loss or signal dropout, it all works perfectlyRecommended!Thank for listening.

    Excellent cable for high speed lines.
  

*by C***Y on Reviewed in the United Kingdom on 28 February 2020*

This is a really good cable and it is hard to find decent high speed cables short of crimping them yourself.I had been looking for a while for a cable so I could move my parents router to a better location for WiFi but being on 140Mbps ultra fast fibre, I wasn't trusting the usual cheap Cat5 cables which have a rated limit of 100Mbps which may be fine if you are on a slow-lane fibre service under 100Mbps.This cable is a Cat5e which is rated up to a gigabit (1000 Mbps) so no problem there.The 10 meter cable was perfect for relocating from the master socket and gave no drop in speed or performance.I didn't see any increase in performance but the internet speed was already sitting at the upper limit of the line so I was not looking for a boost but to keep the existing speed over extra distance and this cable worked perfectly.Very happy with the purchase.

    Expensive but Worth It.
  

*by N***N on Reviewed in the United Kingdom on 15 August 2018*

Every 'Tel' Company is pushing the Merit of 'Fibre' over Traditional Copper Right ?, Inside the Home if your Router is not sat on top of the Entry point, then your probably using ADSL Filters and a cable from a Traditional Phone Extension (with Traditional 'Old' Cable, Instead I previously had run a Traditional ADSL cable from the Entry Point, to my Router in an Upstairs Bedroom where I do all my computer work. But My 'Speed' from my BT Supply had kept dropping back, -  This was the 1st time I had seen 'Fibre' ADSL Cable advertised - Pleasantly Surprised my uplift in My speed at the Router was near 100%, so instead of less than a Quarter of BT's Advertised Upto speed - I'm now getting close to 1/2.and it seems more consistent.
