Hi,
Looking at the stats using Roseway tool in the HG612 modem I found this:
xdslcmd info --pbParams
xdslcmd: ADSL driver and PHY status

Retrain Reason: 2
Max: Upstream rate = 9240 Kbps, Downstream rate = 62176 Kbps
Path: 0, Upstream rate = 3998 Kbps, Downstream rate = 38000 Kbps

The U1 band line and signal attenuation differs too much each other.
Can this be caused by bridged taps ?
I'm concerned because the attainable rate at upstream is too low compared to other users here.
Any advices are welcome.
