Low downstream and high upstream - I guess I need to take time off work for a visit ?
Our hub 3 has been struggling even morethan usual today, with several occasions where it dropped connection and then strugggled with a cycle of green flashing lights before I power cycled it. From what I can see the downstream levels are all low (too negative) and with only one upstream channel with high power and 16 qam theres something wrong in cabling terms ? I'm not sure I can face the hassle of the telephone obstacle course, and even if I do I'm not sure I can arrange to be at home when the option comes up for an engineer visit !
