My broadband download speed is continuously a third of what I expected and about half of what I used to get. I reported the fault online on 5 September, but I've had nothing back besides an automated reply.
My broadband package was upgraded from Unlimited Fibre to Unlimited Fibre Extra on 4 September. My download speed increased from 37 to 51 Mbps for the first half day of the new service, but then dropped to 20 Mbps, and has stayed steady at 20 ever since. Upload speed is good at 18+ Mbps. Dialing tone sounds normal.
I have tested many times at various times of day, in many ways, including by wired connection. My equipment (and the way I use it) has remained the same throughout, apart from a brief period of trying a different router. Of course I've tried rebooting the router as well. I have professional IT experience (although I'm not a networks expert).
Plusnet, please switch me back to full beans. My Guaranteed Minimum speed is 54.6 Mbps, but I will accept 51. I know from BT Wholesale reports that my line is still capable of that.
