Interpet these figures for me please !

Zimmerframe

Newbie to the world of "real" broadband, so don't really know what kinda figures to expect as my local exchange was only broadband enabled last month.
Am on the eircom 7Mb package.

I'm a bit confused here my ping times are usually poor 500/600/700 ms and my speedtest.net seems poor



but straight after the above speedtest, I downloaded (without download manager) a rapidshare file of 63.5Mb in 1min and 31 seconds and my download manager normally reports a speed of >700 Kb/s.


My line stats from the router, are as follows.

Line State Up
Modulation DMT
Data Path Interleave


Downstream Upstream
Max Allowed Speed (kbps) 7168 384
SN Margin (dB) 9.40 18.00
Line Attenuation (dB) 38.00 20.00
CRC Errors 890 14

Is what I am getting normal /OK ?
Are my line stats good enough for 7Mb broadband ?

Thanks

Your attentuation is low enough that you should get the about the full 7 megs down and you're synced at that accordingly, but your line is noisy. Can you hear crackling if you listen through a handset?

Cheers m8, since you posted I gutted the house, disconnected all phone lines and wired the eircom master socket to the incoming cable direct.
Now I get these line stats.

And my speedtest.net test has got worse lol




To answer your question, I don't notice any crackling in the phone, but I almost never use it anyway, as I only have it for broadband.

Are you using wireless? No errors on that stats set though I notice. Left a torrent client or the like running?

Zimmerframe

Yes m8, using wireless at the minute, but I tried it with direct cable connection and it didn't improve my ping times.

Also any experts there, in real world terms, will the difference in my line stats in my second post vs my first post make any difference in the real world, or will I just connect everything back up again.

The no errors m8, are probably just the result of the fresh start up on the router.
Definitely no thing running like torrents etc, but like I said when I download from rapidshare etc, I seem to be getting full speed, don't I ?

The slight change in line stats won't have any bearing, you already have a low enough attenuation and are syncing at the correct speed. Try pinging boards.ie and see what the latency is there.

Success rate is 100 percent (4/4)
round-trip min/avg/max = 30/30/30 msec

It must be contention m8, because when I try speedtest now (after midnight), I'm getting a ping time of 71ms vs >700 a half an hour ago. ??

Could have been Eircom's infrastructure, there seemed to be an outage on the Eircom.net site earlier tonight.
