I changed back to the Billion on Wednesday evening, and after some personal memory trouble with passwords got sync of 6772 kbps with 6dB SNRm. Overnight and through yesterday until about 4.30 p.m, though the noise margin was more volatile and errors greater, it seemed, than the 582N.
Around 4.30 p.m the connection dropped and was restored @ 5427 kbps. (The same sort of reduction , from memory happened with the 582N).As for some time I was away, I did not notice until late evening. From approximately 5.00 p.m. to just after 6 SNRm went beserk.
In theory I can get more by tweaking the margin, as I had done before, but am now loath to. I am using Open DNS, if relevant.
Another oddity is that although the SNR graphs have kept the same format throughout, the Y axis of the Speed graph changed. I used to be 0 -10000 kbps, but since this evening 0 – 300000 kbps. Down is almost off screen and Up has been banished to the Underworld.
Further commenti if you wish, please. Is my router probably suspect?
