When you swapped your ISP cable, was you previously getting CRC errors,? I have always thought that some ISP cables are better than others?

I was getting some CRC and ES errors but not enough to cause DLM to react.  The CAT6 is much thicker cable and is twisted to reduce interference.  It can only be better than the ISP provided ADSL cable.

As an example, my RAM usage stats look like this with AiProtection off.

I always flash firmware twice with a factory reset each time.  I do get spikes in CPU usage.

Today swapped the ISP provided ADSL cable to a CAT6 one.  After over 6 hours connection no CRC or ES errors downstream.  Hoping it stays like this.

How is everyone’s memory usage? I’m on the stock 585 and not using AI. It seems like RAM usage is increasing 1-2% each day. Currently on day 12, and 260MB used (57%). At this rate, will I be out of memory in 43 days time?

I am on beta585 and don’t have any RAM usage problem.  I do no use AI as everyone seems to find it buggy.  Sitting on 180MB used for 3 days now.

@UK Sentinel, I have not heard anything back from Asus regarding possible upstream SNR bug.  Seems like they have so many other more important bugs to deal with.

It is the CRC that you need to keep an eye on, just incase there is to much noise on the line, yours stats are fine at moment, but keep an eye on CRC/s and if the rate per day increases etc.

Thanks, I will keep an eye on the CRC and ES errors.  What level is considered normal?

I am back on beta585.  DLM has now given me full sync speed with a bit of room to Max rate.  Surprising as it’s been freezing cold for the past 2-3 days.

Are these error counts acceptable for VDSL2?

I will give it another day or so, then chase them if they do not get in contact with you. I can only push my luck so far with them?

Thanks, hope they haven’t introduced new bugs.

@UK Sentinel, are you able to chase Asus on my feedback?  Haven’t heard anything back from them.

I would have thought so, as SNR value that high, the DSLAM/Exchange may think it will would require at BT OPENREACH visit, so goes into default mode, or stays the same etc. Best to SEND ASUS a Feedback form if you are running Official Firmware, let them know about latest bug, mention UK Sentinel at beginning and I will drop them an email also asking them to keep an eye out for your feedback

I have sent feedback and mentioned your name.  Will revert back to beta585 which has been most stable for me so far.

This is interesting as I also noticed my SNR value was higher than norm, around 10, but I assumed it was due to a lot of testing I was doing at the time, ASUS DSL-AC88U Firmware version 1.10.06-Build585 did have a driver update ad whether the value are being reported incorrectly is another option? Hopefully others can say also if they have noticed similar reading

I thought the upstream SNR had gone from 15dB to 7dB due to the cold weather.  But it was actually due to firmware change.  With beta585 (and the HG633) the upstream SNR is 15dB but with official 585 and beta586 it is reported as 7dB.

Could that have stopped DLM from reducing downstream SNR target?  All other line stats were virtually identical with the different firmware.

There is something wrong with the official build585 and beta build586.  I had a full DLM reset on 07/11/18.  With those 2 builds DLM refused to reduce my SNR from 6dB to 5dB.

I then decided to revert to beta build585 late last night on 17/11/2018 (just to experiment).  Within 6 hours DLM kicked in and reduced SNR to 5dB.  Stats attached.

The only difference I noticed was upstream SNR is higher on beta585 than the other 2 firmware.

Ping seems good, I assume you are happier ?

The connection is a lot more stable now with new wiring and port change from Openreach.  The pings are really good so far.  In total it took 4 visits from Openreach with the final one a full DLM reset.  3 of the 4 engineers were amazingly helpful.  Hopefully the AC88U doesn’t start to play up.

Now that the firmware has stabilised, hopefully Asus can iron out the last few bugs and start adding the missing features.

Thanks darkblak and UK Sentinel.

You wait ages for a bus and then 2 come along at once……

I have flashed the new beta build586 twice, once with UI factory reset after flashing and once with manual factory reset after flashing.

Looks like firmware version 1.10.06-Build585 not available yet or removed from the server for the Annex A model

edit:  It’s there now

@UK Sentinel, any further news on the new stable firmware release?

I had another Openreach engineer visit today, wasn’t actually told about this.  He checked the line and did a full DLM reset.  Connection seems to be back to normal.  In a couple of days should get full 80/20 MB again.  Apparently the last guy didn’t actually do a reset.

Looks like you are back on Interleave (Downstream) so hopefully G.INP should come back in around 3-4 days if nothing else has issues. BT must love you

Luckily I knew the guys, the last one used to live a few streets away from me.  I have basically had everything changed that could be changed.

Am I right in thinking that G.INP reduces the errors and increases sync and maximum attainable?  I was previously told by TalkTalk to wait up to 48 hours for DLM to do it’s thing.
