Why we love it

Enhances WiFi strength significantly.
Preserves strong connection quality.
Allows optimal router positioning.

Main Highlights

NOT SUITABLE DEVICES: This cable supplies your router with the main incoming signal from your wall box and is not designed to connect devices tonthe yellow ports on your router.
MOVE YOUR WIFI ROUTER: Connects your ADSL 2+ 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 CAT5e cable with Gold Plated pins gives improved connection speeds when compared to the standard, flat, non twisted pair phone cables usually supplied with many routers. We supply FREE Cable clips with any lengths above 5 Metres
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
CAT5e FOR FASTER PERFORMANCE: These twisted pair cables offer critical shielding from the many sources of electromagnetic (EMI & RF) interference that can cause regular dropouts when the standard flat type RJ11 phone cables are used. This type of screening creates a magnetic field as the signal travels through the twist which creates up to 10 times more external signal rejection and in some cases can increase speed significantly depending on the type of cable it is replacing
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
