      Question Upstream Speed & snr

      Netgear DG934G stats for my heading, show 192 kbps with a noise margin at 3db, which seems very very low, compared to my previous IPS stats of 448 and 15db snr.

      Conversely downspeed (capped at 2048) has a massive 23db snr, where previously a max of 12db was unusual and normally 9db was common.

      OK, I'm on the cheap as chips freebie service ... but is 3db, Sky's benchmark downstream snr?

      I've had the misfortune to communicate twice with Support. The initial response on both occasions, really was a pretty poor show, but once the giddy heights of T3 were traversed things improved immeasurably. I think avoiding the facility, and preserving reason in the process, if at all possible will be my route - so I wondered if anyone else had knowledge of upstream stats?

      As you are on Base with 2Mb/2Gb limits, you are obviously not a serious downloader, so do you have any real need for a high upload speed? I ask, as contacting Sky about the issue could result in your download speed being further capped, which could take a long time to sort out.

      Presumably, from the thread title, you mean upstream?

      Actually, it's not clear if there is a default upstream noise margin db figure (unlike downstream which is 6.9db). That's because the way ADSL works, the upstream takes the first part of the available frequencies to fulfil the assigned upstream speed and then the router uses the remainder for the downstream. As these first frequencies are lower than for downstream the attenuation figure is higher and this together with the upstream sync being 768kbps at most, the upstream noise margin db is therefore usually pretty high.

      Yours at 3db is very unusual as is your sync of 192kbps. You have a problem and it's not that your connection is capped. If you reboot does the upstream stay the same? How about if you connect via your test socket?

      Re: Upstream Speed & snr

      Thought it probably was ( you mean 6.9db though?) but it's unusual to see an upstream margin that low for the above mentioned reasons.

      Re: Upstream Speed & snr

      Re-booted and same stats as before upstream 192, Noise margin 3db. Anyway I'm not coming to any harm and rather than commit any more novice errors on here I'll leave it alone I think - thanks for your help.
