Interleaving or not? and hec and fec?

Just teased this out of my netgear router, anyone any idea what this means and should my downstream RX have that many FEC's ??

[Upstream (TX) Interleave path]
CRC: 17 FEC: 4624 NCD: 0
LCD: 0 HEC: 544

[Downstream (RX) Interleave path]
CRC: 1552 FEC: 102443367 NCD: 0
LCD: 0 HEC: 0

[Upstream (TX) Fast path]
CRC: 0 FEC: 0 NCD: 1
LCD: 0 HEC: 0

[Downstream (RX) Fast path]
CRC: 0 FEC: 0 NCD: 0
LCD: 0 HEC: 0

Interleaving is enabled on your line.

No, it shouldn't. These are errors that the modem has corrected so it doesn't matter too much as long as the CRC error rate remains low. However it indicates that the modem isn't managing the line properly to avoid the errors occurring in the first place.

I thought my RWIN might be too high, but according to DSLreports its within range and i'm getting a 98% score, so its not that. My sync has lowered to 6550kbps now mind.

RWIN is unrelated to your modem stats. Often a resync will solve this problem.

I get millions of FECs and they cause me no problems at all. I have a Speedtouch and I'm not sure exactly what gets counted as a FEC error. My own counter actually wraps every few days and it is huge.
