Over the last month, my fast fibre has dropped from a constant 72meg (for the last 2 years) to today 12 meg tested on the talktalk speed test. Speedtest.net, thinkbroadband and my SamKnows box also show a very large drop. Router Sync speed has only dropped from 80meg to 69 meg. I have changed the router from HG635 to the HG633 and that made no difference also connected to the BT test socket with appropriate filer. I connect via wired 1Gb network normally, but also 5ghz wireless show slow speed -that’s normally 70meg. All the speed tests show a download looking like a cross section of mountain range—normall it’s a flat download.
It maybe coincidence but this all started when I signed up for the new all inclusive package—up to the beginning of October my speed has been a constant 72Meg for several years-
