There is insufficient detail about your broadband problem. If you have undertaken all of the PlusNet installation checks and are sure that the problem is on the in-coming supply side of your Open Reach master socket, then Open Reach may have inadvertently changed your IP Profile speed.
To lookup your IP Profile, go to BT Wholesale Broadband Performance Test and perform a speed test. Click on the diagnostics tab at the bottom of the speed test results page, on the next page provide your line information, then click to continue. Wait until it has finished interrogating your local Open Reach exchange. The diagnostics page will then appear. Look at the bottom of the box beneath the 1. Downstream Test. In small text you will find the IP Profile speed for your line.
Your Open Reach IP Profile is automatically created in the telephone exchange. Its value fluctuates to ensure that your line speed is always stabilised. However, your IP Profile may have got stuck at a slower line speed. If the slow broadband speed persists more than five days, you could raise a PlusNet Fault. Invariably PlusNet are unable to intervene in the Open Reach automated process, but they could assign an engineer to check that there is not a serious fault with the exchange monitoring equipment.
Hope this helps. Kind regards.
