RT-AC86U 384.16 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. ...

Downstream rate = 39709 Kbps =

“your downstream SNR reduced from 8 to 6” which is good

No i have not rebooted since i plugged it in.

That strange, it looks like DLM did resync during the day which is not common. However it’s looking good as your line is nod banded so far, so things moving right direction 👍

@Bully

After I look closer I see that your card (in DLM) is on different fw than mime, that’s explain sync during the daytime. To see better differences I put zyxel on my line, and the thing which I realised straight away is bitswap, on yours is in thousands on downstream where mine looks like that

Bitswap      18/18      1/1

Don’t want to predict evil but I think there maybe some issues on your line, could be noise on some tones, that’s why bitswap working so hard, because some tones are unusable bits are swapped that is probably why you had so high amount of errors with draytek, hg612 seems to use different tones or either manage to bitswap better.

Could you please post pictures of snr graph and hlog from dsl stats program. (when you got time of course)

@Mrk26 – can you show your CAB card FW details for comparison – makes for good future reference and for others following this thread currently

@Mrk26 – thanks, with all this talk of Broadcom Modems, I am tempted to put back in my HG612 (3B) just to see how well it works for my line (I must be bored)

I put mine back in the name of science , so far no issues with it, slightly slower on sync speed but I knew the price. I think my cabinet going to blow up anyway, as attainable speed keep dropping pretty much every  week, what didn’t happened in the past.  No issues with vigor as you know so I may put him back next weekend ( I must be bored too ).

Below my recent stats, snr on downstream 5.8db was 6.2db when I connected but obviously attainable speed drop so snr follow. Also bitswap bit higher since connected but not much.

I think it may be interesting to see @Bully bitswap per minute graph as well.

@Bully bitswap Graph will be an interesting comparison

Right, I have to rebooted zyxel modem as I have bunch of CRC error, looks like it can cope properly with snr below 6db (on 6db profile). Will keep an eye on it till rest of the day, draytek may be back on duty sooner

So your science experiment has finished ;-)

Well still running and keep an eye on it from time to time. In the mean time I was browsing internet about g.inp on eci, and found something interesting… This wonderful future enable FEC on downstream for broadcom modem on eci cabinet 😂😂 what convenience me even more to go back to draytek. Therefore not sure how it’s working on Huawei cabinet @Uk Sentinel?
