Hi,

 

I updated to the latest Merlin firmware this morning (about 9 am) and since doing so my NE CRC count has gone up to 326598 over 5 hours.  The FE CRC/ES count has not increased at all.

NE CRC Count            :   326598     FE CRC Count         :     4011
NE ES Count             :     8819       FE  ES Count         :     2625

 

Me updating the firmware seems to be the only connection to the spike in counts.

What could I do to fix this?

Is the EC and CRC from a DrayTek modem attached to the ASUS RT-AC86U, I forget what you have

I cannot see why the Modem would be effected by the recent upgrade of your RT-AC86U, Maybe worth just switching both the modem and router  off for 15 minutes and then bringing back online and see if that settles down the modem etc.?

But this is most odd ?

Any clues from the ASUS Syslog as to problems ?

I would power everything off as mentioned above (when family permits) and see if it happens again,

If you have the same high CRC count after power reboot, try reverting back to 384.15 and see if this is still cause of high CRC’s count from DrayTeK modem ?

Ok,  Will have to be after midnight or first thing in the morning, don’t want to upset anyone in the house, and with the lock down i cant escape the carnage .  I will let you know how it goes.

That sounds like a plan

Turned off router and modem at 18.10, it has made no difference  –

stats after 40 mins

NE CRC Count            :    73740       FE CRC Count         :     4011
NE ES Count             :     2630       FE  ES Count         :     2625

Try reverting RMerlin firmware back to previous version, I am surprised the reboot did not work

Right, I reverted back to 384.15, this has made no difference after the flash and a power down for 15 mins.  It must just of been a coincidence.

My interleave depth has gone up over night –

DS Actual Rate          : 34416000 bps   US Actual Rate       : 10666000 bps
DS Attainable Rate      : 42690000 bps   US Attainable Rate   : 10841414 bps
DS Path Mode            :  Interleave    US Path Mode         :        Fast
DS Interleave Depth     :     1441       US Interleave Depth  :        1
NE Current Attenuation  :       20 dB    Cur SNR Margin       :        5  dB
DS actual PSD           :     6. 4 dB    US actual PSD        :    12. 9  dB
NE CRC Count            :    48488       FE CRC Count         :     4012
NE ES Count             :     1411       FE  ES Count         :     2626

These stats are 15 minutes after the 15 minute power down of router and modem –   NE CRC Count :  48488  FE CRC Count   :   4012 NE ES Count : 1411.  The DS Actual Rate of 34416000 bps has dropped over night from 40251000 bps.

 

Is there anything I can do to get the errors down and my interleave depth down in way of snr or speed capping or should I just leave things alone?

That does make sense that the Asuswrt-Merlin firmware had no impact on your DSL line faults.

Yes your Interleaving has kicked in, it is not a happy ECI DSLAM or DSL line.

Did you ever try your BT HG612 modem, or is my memory fading as given the long history with your line a Broadcom DSL chipset is more forgiving ;-)
