To put a bit of meat to this, there are many, many forum threads on 2860Vn+ consistently and randomly dropping connections. I have just had my provider, Plusnet, call Openreach out, and the most diligent engineer came out and physically replaced the entire cable from the microfilter in the house all the way to the exchange, as the line was recording near and ( mostly) far CRC errors. Then, the line was rock stable at 68Kbps until the exchange end started re-training to a higher d/l value at 4 in the morning.
I then started getting ridiculous number of dropouts, SNR values of -6 ( minus six), and the line just would not stay up. I updated firmware, regressed firmware, changed vector versions but all to no avail.
The line was then dropped overnight last night to 65Kbps, and it is rock steady again. I interrogate my 2860 with scripts from a raspberry pi, & produce rrd tables of output, and you can clearly see the correlation with reduced d/load, SNR and increased reliability, so an ability to influence this at my end would be great.
Simple internet searching shows that this is a common problem with many other people with 2860, which I wish was not the case, because as a network/unix techy I really like my 2860, however I absolutely must have reliability as I run webex/voip conf calls etcetc from home.
If there was a way in the negotiation to control the max bandwidth I am absolutely convinced it would resolve this issue, as I need reliability over max throughput.
Any advice/pointers would be much appreciated.
