Sync Speed for Line Attenuation

GeForce · 17 Mar 2009 at 07:30

Hi all,

Just moved to Be Unlimited, it's great so far. Much faster than my previous connection. Currently using the BeBox, but have a Sky Netgear DG834GT on its way to me, which I intend to flash with DGTeam and use with this connection.

For a 30dB attenuation downsteam I should be looking at an average line speed of 13mbit. However, as you can see from above, only getting 9Meg really.

The ring wire has been removed, and the house only has one phone socket into which the ADSL line and phone are plugged in via a filter.

I realise that graph is only a rough guide and actual speed depends on loads of other things, but:

1) Should I see any sync speed increase with the DG834GT?
2) Is there anything else I can do to bump line speed up a tad?

Cheers

I should be getting 11mb but only get between 8.8 and 9.5 (ish).

You also have to look at the SN margin lower means faster, but you could end up more unstable. Higher mean slower but more stable connection. (tell me if Im wrong)

You also have to take in to account your phone line quality, noise on the line etc etc.

I should be getting 6, i sync at 4 and only get 2, LOL.

according to that graph i should be syncing at 5 and getting 5!!

Send a ticket to BE support and ask to be switched onto a 6dB fastpath profile for the time being. Should improve your sync speed nicely

Yes, it looks like OP is on the 9dB profile. I'd suggest OP asks to br switched to 6dB and monitors the connection. If it is stable, then try 3dB or adds the change to fastpath. I'd only make one slight change at a time, monitor, then change accordingly. My downstream attenuation is 30.5 and i sync at over 15,000kbps with the odd disconnect. (snr profile 6dB, no fastpath).

On the Be website, on you're profile, bottom right you can change your speed and enable fastpath.

Choose, Standard Setting and Gaming Mode On!

This will give you 6dB and Fastpath!

Done all the ring wire and test socket guides?

Thanks all the replies

As you probably know you can switch yourself over to 3/6/9dB profiles from the member center.

I was indeed on the 9dB profile and I switched over to the 6dB one this morning to see what happened. It synced at around 10000/1000 kbit for a few minutes, and then dropped to what you see in the screenie below. It's been fine since, no more reconnects, so this seems stable.

737 kbit upload is a little less that I'd like, but I'm willing to sacrifice some of my download speed. Is this what fastpath would achieve? Do I need to request that with a support ticket?

What is "gaming mode" in the member center?

Thanks again people

Read my posts mate.

Gaming mode just means Fastpath.

Sorry, when I was typing the reply your posts hadn't appeared yet!

Thanks though, going to try this now. For my own reference as much as anything, 6dB without fastpath seems stable for ~11 hours.

Just a suggestion, if your SNR is still showing 15dB or thereabouts after you've changed your profile then raise a ticket as the member portal system might not be playing properly.

tolien · 17 Mar 2009 at 18:20

It's 15dB up, though that is quite strange...

Yes, that is weird. Linked to the upstream sync which is rather low for Be too. IIRC they all have up to 1.3Mbps upload speed apart from the Pro option. I'd give them a call.

GeForce · 17 Mar 2009 at 18:47

Right, still on 6dB profile but using Gaming Mode/Fastpath. Here's what I'm seeing now:

So SNR margin appears to be ~6.0dB for up & down now. Been running for half an hour or so like this and haven't had any disconnects yet (touch wood). As you might have guessed, I don't know very much about DSL technology and it's workings/systems.

Anyway, DG834GT is arriving tomorrow, so shall wait to see how that fares. We've never had fantastic speeds on this line, the exchange is a fairly long way away.

If the up/down sync speeds stay as they are in that screenshot I'll be happy. On BT we used to get 450/3500 up/down, so this is a vast improvement.

Cheers again all, any more suggestions/thoughts/criticisms welcomed, and I'll keep this thread updated.

Hamster · 17 Mar 2009 at 19:29

Upstream sync and snr looks better now

I would monitor your connection over the period of a week or so before making more changes. No disconnects in half an hour will not tell you much unless your connection is really at the limit.

You're not on fastpath mate, you're still getting FEC errors.

Have you confirmed the profile after you selected it?

SNR is Signal to Noise Ratio and you want it as high as possible.

Ah, do the FEC errors (what are these?) represent a non-fastpath profile?

I have indeed confirmed the profile, and have just been back to the member center to check that it's still set to 6dB/fastpath - it is.

Had a couple of disconnects, current sitation is thus:

Once again, I apologise for my ignorance on this subject! And of course, thanks a lot for the help

Swifty55 · 17 Mar 2009 at 22:06

Yes, the show FEC errors means you're not on Fastpath.

Can you post a screenshot of the options you've got enabled on Be*'s profile page?

GeForce · 17 Mar 2009 at 22:08

Interesting, didn't know that
