It seems that BT Wholesale have been trailing a new device called the iPlate and surprisingly it has nothing to do with Apple either. This device could speed up internet connection by just adding it to your home network.
It works by reducing the electrical interference from other household devices like the set top boxes, television, and of course the famous interferers Christmas fairy lights. These things can slow down the internet connection speed considerably according to BT.
This device is called the Interstitial Plate (iPlate) it plugs into the main phone socket and its job would be to reduce noise and therefore increase the speed, but this sounds like something that would not do anything really, but should the speed be ok, then it would take all of the credit. For anyone who suffers from this problem, the £10 cost is not much to splash out if there is even the remotest chance of it working.
