Speedtouch 585 and line stats

[Veggie]

Hi, I brought a 585v6 few months ago which give me a slightly better sync speed...

Netgear DG834G v2
Day / Night
Attenuation 55/31 Attenuation 55/31

SNR 6/16 / SNR 6/18<---Upload SNR better at night?

45**/488 36**/488

Speedtouch 585
Day / Night
Attenuation 57/31.5 Attenuation 57/31.5

SNR 6/14 / SNR 1/14

48**/488 4000/488(To many errors to be usable)

3-4 months ago my SNR target was uped to 15 thanks to my first netgear router falling 1 night(Fell on floor then tryed to reconnect every 30 or so seconds due to power loss for about 8 hours atleast)

Yea so I brought the speedtouch since you can manually set your own SNR target but my problem was the speedtouch seems alot less responsive when loading pages and the upload speed was abit lower even though it was still synced at 488Kbps and pings are generally a few ms higher.I thought it might be because I'm pushing it to hard with low target SNR resulting in more errors so I tryed it at default SNR target(15) and it was still the same.

Since I'm just about to migrate I thought I'd ask to see if anyone has any ideas why the speedtouch is less responsive than my netgear.

I can't say i've noticed a difference. I've used about 10 different routers to test out various things and in terms of general browsing and download speed i've found the speedtouch to be much more impressive and repsonsive. Have you checked that both routers have the same MTU value?

As your attenuation is 55ish that indicates quite a long line. Anything above 3Meg on that sort of distance is very good to be honest. Your pings are higher as BT have put you on Interleaved mode, probably at the same time as upping your SNR to 15. We can turn Interleaving off once you have migrated and that will see your ping times almost halve.

On that speedtouch screenshot above, you still have 13dB SNR so you should be able to wind the SNR slider right down to get more speed out of it, as when you are on a 15dB SNR profile this still leaves around 8dB SNR onces that slider is at the bottom. As long as it's over 6 you should be ok.

Looks a good speed. I have a long line and my att is 63db and I get about 960kbps/380kbps.

Yes that screenshot is old and I was to lazy to set the 585 up again:p but if i set the SNR to 6 it would sync around 4800 - 5200.I can't find the MTU value on my speedtouch but on my netgear it is 1458.

The DMT screenie says the router is a 576, not a 585....and that version of DMT isn't exactly recent. :confused:

Sorry that was with the router AOL gave me when I first join;) Will upload a picture with my 585 connected in a few mins:p

There you go:o

[James]

Very, very decent line there mate!

[Ircsum]

I think I read somewhere that AOL recommend a MTU of 1400....wonder if that's an issue here? Default MTU of a 585 is 1500, I understand.

Ircsum.

[James]

Correct. Although I think AOL support 1450 now too.

You can only change the MTU through the CLI on a Speedtouch I think :S

My activation with Adsl24 is on the 21st, Will have a mess around with speedtouch then:cool:

I got an error message saying that my 585 v.6 has a new firmware that's not supported!

[James]

Yes, Speddtouch have blocked the use of the DMT tool in firmware 6.2 - they don't want people messing about with it.
