This is ongoing - but the YVM104 error has not reappeared.
Yesterday OR visited again and confirmed the DR was fine at 58Mpbs down - and also confirmed that he was seeing the broadband download throttled at 23Mpbs on his own device. This cleared back to 51Mpbs on a router reboot.
He removed all devices (including tv box) so his was the only one - and still fixed at 23Mpbs.
He did a 'lift and shift' and I was then getting the expected 51Mpobs downooad. He said the card I was on was reporting errors and that was possible that was dropping the download speed - but agreed that a fixed drop every night is more likely to be an automated process running somewhere but perhaps relted to the card errors..
He said there were no errors at all on the new card and all should nw be good.
At 5.30am my broadband download is back down to a constant 23Mpbs. One day last week it had dropped to 14Mpbs.
BT keep closing the fault every few days say "I have told them it is faxed".
BT close my complaints after a few days without speaking to me or doing promised callbacks.
We know it is not a rougue device unless it is a inherent fault in the Box Pro - we are on number three now.
The issue occurs with only one PC connected via Ethernet and wifi disabled. But BT will not take open a fault if wifi is disabled. It also occurs with no Ethernet devices connected and just one signle wifi device.
