I switched from Plusnet standard broadband to Talktalk faster broadband on 1 October for the extra line speed. I thought the small additional cost would be worth it.
Prior to the switch I was consistently getting just over 34 Mbps with Plusnet.
Last Friday 9 Oct, I contact Talktalk via online chat because the line speed had dropped to 20.32 Mbps. Person I chatted with said their was a "lock" on our line and I should switch the router off for 30 minutes.
After switching the router back on, the speed had increased to 29.21 Mbps and has stayed at around that level ever since. The person I chatted with gave me the impression that Talktalk would monitor our line and the speed should increase within two days.
So currently Talktalk faster fibre is 15% slower than Plusnet standard fibre and cost slightly more per month.
