Hi,

Upload speed can drop as low as 1.5Mbps during the day. Engineer visit was booked for 5/1/21, engineer called and said they could see issues but issue was not at my end so site visit not necessary, issue should be fixed in a couple of weeks.

Still have the issue, status on by postcode has no issues, any assistance much appreciated modem status below:
