Sorry for the delay in response, I thought Id give it test before coming back. @johnson I had a go with the firmware, the older one made no difference, however the newer is a bit better, it fluctuates more only by a couple 0.xdb, but I think it accurately displaying it, as supposed to the old firmware which didn't and just stuck the same. The newer firmware still drops the SNR and does not come back the next day, however it wont go below 4db so far so there is an improvement, but not ideally where I would like it. Hopefully it wont be 1db this weekend again. So I still think it could be dsl driver firmware related as this version has helped a little somewhat, hopefully Broadcom will release a better version in the future. Many thanks @Johnson for amending the firmware for us to use. It is only bothering me as I either think something is wrong, or its not reporting correctly or my line will never resync if the DLM sees the same SNR and thinks the line is struggling. Plus I like to see the correct SNR so i know what my attainable is, so know if I can resync and or if there extra speed left in my line. Plus I dont fancy the line resyncing every 10-12 days if the SNR gets too low.
@Weaver, bitswap is enabled on both upstream and downstream, I assume it will be on the eci cab im connected to. How I know when to resync the modem is when the SNR is high generally when the DLM improves my lien the SNR rises a bit I have often noticed and I am seem to get the best speed then. The ES and SES errors look like they were when I had the HG612 if not as bad, not sure the extra in built filter is helping. I am aware of the lower SNR is better, would be great to have 3db profile, but that will be forever wait with an ECI cabinet, along with G.INP and the rest.
