BT Broadband Accelerator filters out interference from your home phone wiring to help your internet go faster. There’s one free for every BT Total Broadband customer if you order it here – and you only need to pay for the postage which is £1.20.
There is a mini test there as well to see if your socket is compatible.
“In tests the I-Plate has been shown to boost line speeds – typically by 1.5Mbps.” Each house and line is different however.
If you’re not a BT Broadband Customer you can still try your luck if you have a BT line they may give it to you.
Also for everyone else completely BT free you can get it for around £11.73 here
