Title: Best ever sync!
Post by: jameshurrell on Oct 13, 2009, 22:37:34
My Netgear DG834 v4 is performing very well on WBC, tonight it's synced as follows:

Connection Speed    18804 kbps    1212 kbps
Line Attenuation      27.0 db            11.8 db
Noise Margin            1.5 db             6.3 db

It's been up now for over 12 hours at that rate - the noise margin is very low though, so I don't expect it to last. IP profile is currently 14000.

Just a comment really - this line seems to suit WBC, although I've never seen it synced this high before. 16000 is about normal.

I wouldn't expect it to hold sync past 2am with a noise margin that low, although you may just be lucky.

I would be thinking to myself right now whether or not to force a resync now. That would have the effect if reducing the sync, but giving a bigger margin and therefore more stability.

Great sync, but I don't think it'll last - a 1.5dB SNRM is pretty low!

Like Rik (I think) my target noise margin seems to have been set at 3db and it often creeps down to 1.5db.  Current stats since the 4th of this month are:

Connection Speed   17657 kbps    1144 kbps
Line Attenuation     28.0 db      12.5 db
Noise Margin           2.9 db         6.0 db

The previous resync lasted for over five weeks with similar stats.  My stats are almost identical to the OP's, so I'm inclined to be slightly optimistic about his line staying connected.

:fingers:

Edit: My profile is 1500kbps
