Jammy.

bobleslie · Jun 02, 2009, 11:35:02

Thought you might say that.

Rik · Jun 02, 2009, 11:35:56

You were right. I expect to see little change downstream, more upstream.

Are you able to telnet from the Windows machine to itself in a cmd window ? (Presumably Vista run as administrator)

telnet open localhost

If not, you need to a) ensure the telnet service is installed and started, and b) Windows firewall (or other) allows the connection.

I think I am as it allowed me to enter debug mode but after that it's a page not found when I try further commands.

I appear however to be hovering between this thread and the unsuccessful thread at the moment. After a successful migration I keep losing connection to the Internet although my connection as far as IDnet and my router are concerned is reporting as being connected.

I've factory reset the router to see if that helps sort the issue out which appears to be router based.

Rik · Jun 02, 2009, 15:38:35

You this week, me next.

Steve · Jun 02, 2009, 16:03:05

Is this a wireless based connection or ethernet connection? Are your DNS servers set manually or automatically I ask as there seems to be an issue with the latest GT firmware with manually set router DNS servers . If it picks them up autmatically the problem of apparently being connected without an internt connection seems to dissappear.

zappaDPJ · Jun 02, 2009, 16:22:49

Interesting. It's Ethernet for me although there are users that use the wireless facility. DNS servers are set manually so the next time I lose connection I'll try switching to automatic.

[EDIT] I've also got another modem (thanks to IDNet) on its way to try.

zappaDPJ · Jun 02, 2009, 18:25:30

Tried using an automatic setting but still getting disconnects I'm afraid.

Sebby · Jun 02, 2009, 20:16:53

Does anyone have a ST585v7? I've read that it has the same chipset as the Netgear DG834Gv4. I'm not sure the ST585v6 has the same, though; if it does, it means it's a firmware issue rather than chipset.

willgoat · Jun 02, 2009, 20:34:39

I am on the Plexus WBR-T2 V 0.2 (Tenda TWL548D) but only connected at this... hmm...

Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 15320 kbps(DOWN-STREAM), 852 kbps(UP-STREAM)
IP profile for your line is - 13000 kbps
Actual IP throughput achieved during the test was - 11807 kbps

Will it likely improve?

rireed3 · Jun 02, 2009, 20:36:18

ST585v6 is definitely Broadcom, but the CLI is different between DG834v4 and ST585v6. I'm still working this out on ST585v6.
I don't have any information on TG585v7.

The profile is correct for that sync, and throughput is about 90% of the profile, so it's unlikely.

willgoat · Jun 02, 2009, 20:41:53

Ah, kinda disappointed then... I am kinda 215m from my exchange after all.... so it won't try to sync at higher speed in the next few days?

Sebby · Jun 02, 2009, 20:44:21

Ah, okay. In that case, we need to look at ways to improve sync, if possible. Could you post the line stats from your router?

willgoat · Jun 02, 2009, 20:50:01

Thanks.. but i can't seem to find any line stat on this cheap modem on the web interface, that's what kitz say as well, need to hook up my other modem and see.

I finally managed to connect to the router Telnet server only the ChipSet Vendor Id (I assume this is what I'm looking for?) is not returning any information. All I'm getting is the Channel info

Steve · Jun 02, 2009, 22:42:12

I wonder if that's because the router cannot display a vendor ID that is unknown to itself.(database)

You connected to 192.168.1.1? My 100 doesn't have a set username or password, and if you get into it type show adsl hopefully that should show you your stats.

Hi Willgoat

The main hindrance on such a short line appears to be the high SNR margin at 21db. It may be that BT have set a high target for some reason like lots of re-syncs. As far as I can tell you don't have a lot of errors on it. I have read that people are finding the Dynamic Line Management to be very sensitive on ADSL2+. I lost some connection speed faffing around with routers, but after I was connected for a few days, I had a re-sync overnight and got a very fast connection, almost too low on SNR margin. On 8M Max, after the 10-day training period, it apparently took a fortnight connection to get SNR target margin reduced.

Your line may be somewhat longer than 215m, but your attenuation is still low at 20db. Mine is 24-26 at about a kilometer distance and I get 18.5-19.5M depending on routers.

Richard

Rik · Jun 03, 2009, 09:14:58

I'm with Richard, the sync should be higher, so it suggests noise on the line which DLM is managing by upping the target noise margin.

Steve · Jun 03, 2009, 10:56:08

I looked at those figures for the SNR and margin for the 2 different modems on the same connection, one gives a figure of 21 the other 13. Is this misquote from router stats or is the actually figures being quoted different i.e actual figure 21 and the other the margin of 13 . Any ideas.
