Didn’t have any devices to get the stats from HG612 - modern laptops are rubbish with no Ethernet ports! No old data as at the time of install they had a bigger problem with BT Wholesale authentication failure.
Fault has been logged with BT earlier this afternoon - the noise on line during quiet line test was worst I’ve ever heard on a line, lot of crackling but intermittent (as in 30 seconds good then noisy again, not hours at a time). Got a recording of it just in case needed. DSL connection been up for 4 hours now - a record today.
Thought it might coincide with swaying of phone line in wind, but nope. Some of the external wiring looks rather interesting from a distance so probably will need a thorough check over by engineer next week. The online fault checker came back with no faults external to property but as the only phone cabling is to master socket (no extensions), then it’s all Openreach responsibility.
