O2 Slow?

Mekrel · 7 Dec 2009 at 18:54

After reading around on here and looking at some ISP reviews, it seems O2/Be are highly regarded.

I have awful speeds during the evening, my router currently says I'm connected at the following speeds: 1,049 / 2,150

It's awful, I can't even watch Youtube without pausing every 3 seconds!

I used to be connected at ~6,000 down.

I don't download anything really, Windows Updates, application patches and that's about it. I have 1 x 150GB hard drive with a full install on and it's only half full (so I'm not one of these mass downloaders who abuse the ISPs service).

Is this usual? Obviously I know the network is busy around this time and I wouldn't care if my broad band is slower as long as it didn't affect performance this much

Most likely problems on your line.... can you post your linestats?

your figures aint good !
Have you tried using the master socket with the extensions disconnected?
At night due to noise you will not be able to connect at the same speed as during the day However you should be able to do better. I'm in Southampton and can max out my line during a download (my case 7500)
Utube can be overloaded nothing to do with your line!

Well looks like a fault has developed with my line :mad:

At the moment my internet is lucky to keep connected for a minute, O2 are going to run a LDQ (or was it LQD) test on my line which takes 24 Hours.

I've connected the router to the test socket, you had to for the test according to the engineer I spoke to.

Oh well, typical luck for me really

Without wishing to hijack, i've been having problems over the past few weeks too. Disconnects, 6mb down to 2mb, etc. BT engineer found the line temperamental when he set it up.

How do I get my line stats on the o2 wireless box? Logging in as superuser with the o2 broadband password isn't working for me.

This doesn't work?

No, that works when I telnet in but i'm not sure how to get the line stats that way?

gurusan · 8 Dec 2009 at 12:36

I don't have that router but from googling it looks like after you have telnetted in you type this: "adsl info expand=1"

Flying_V · 8 Dec 2009 at 12:36

Ah great, thanks will try that when I get home.

Locky · 8 Dec 2009 at 17:16

I think Annex M on the op's line might be the cause to be honest.

Mekrel · 8 Dec 2009 at 23:08

Looks like the Master socket has an issue!

In the living room we have this multi media point (basically a massive white panel with cable/satellite/aerial/telephone points all in one). Connected it to this and so far everything is good.

I take it Open Reach will need to come out? Not sure who pays for this seeing as it's private rented accommodation.

If you used the test socket behind the faceplate of the master socket, everything else is connected to that anyway so it's hard to see how that could have an issue without buggering the extensions.

From the earlier stats it looks like you're connection had been unstable and connected at a lower speed but your SNR margin had then gone up (i.e. if you'd reconnected it should have synched up at a higher speed, probably near what you normally get). Your OP's a little misleading too - you're connected at ~2Mbps down and 1Mbps up (so you were seeing zero benefit from using Annex M).
They've then changed you to Annex A, which gives back a small number of download bins that were being allocated (but evidently not used) for the upstream.

Well that was my understanding of the test socket too, unless my line was coincidently fixed as I switched over...

Maybe I'll have to retest.

I noticed the change in Annex - but to be honest, all that you said in your last paragraph went over my head sorry

The way you said them in the OP implied that you were getting a higher upload speed than download.

Before:

SN Margin (Up/Down) [dB]: 6.0 / 15.0

After:

Bandwidth (Up/Down) [kbps/kbps]: 1,107 / 5,261
SN Margin (Up/Down) [dB]: 6.0 / 6.0

You've gained 3Mbps up at the expense of 9dB from your downstream SNR margin. You'd probably have gained the same if you'd just restarted the BeBox.

The whole point of Annex M is to give you a higher upload speed at the expense of download by stealing from the bottom end of the downstream frequency range. As you're seeing, you have to have a fairly good line for it to be worthwhile.
