The Slow Deterioration Of My Broadband Speed


[link to this post]
 
I wonder if I'm the only person who hasn't moved to BT Infinity....who's been getting this :-

After years of slow speeds barely getting above 2mb, by last year my speed had increased quite nicely and was regularly running at 4.5mb.....which is fine for me. I'd regularly be able to watch BBC iPlayer documentaries in HD, which requires at least 3.5mb.

The main increase in speed came around the time BT Infinity was being offered, but I didn't go for it as it is actually more expensive. But....since sticking with the old ADSL, my speed has gradually crept down over the months. In fact it is months since I had 4.5mb. It seldom even gets above 3.5mb now.....and in the past month has fallen even further, and is right now around 2.5mb

I am suspicious about this....whether it is a deliberate ploy to force people to move to BT Infinity.

Post your router stats.

There is no policy to force you to change.

That's a fair few errors for only 25 minutes of connection. What do they look like when the router is connected to the test jack within the NTE ? Is there any noise on your line ?

yes, you should be getting about 4.5 Mag.

Have you removed ring wire?

What are stats when you plug in test socket behind master socket faceplate?

4.5meg, that's a little optimistic on a 52db line. 3.5 to 4 maybe.

Maybe! Kitz says so & OP did for some time. So something broke!

I manage a 4.5-5.5 Mb sync on a 54 db line, I'd say 4.5 is certainly possible on a 52 db line.

4.5 meg is what I got for quite some time....and long periods connected.

What's odd is that my connection is 'dissconnecting' more frequently now, yet the lights on the router still show everything as if connected. Whereas I used to go spells of 60 days without a disconect, its now more like 3 or 4 days.

And throughout all this, the average connection speed just gets lower and lower.

Kay, point taken. The OP needs to contact the CP and see if he qualifies for a fault to be raised for LTB (lower threshold breached)

If it is, then it certainly worked in my case.

I described my line-drop problems in the thread on the last page entitled:

Home Hub 2 Needs Reset Every Few Hours

After a few weeks of this I succumbed to BT's Infinity spam and signed up.

Mysteriously, the moment I did this, the problems abruptly stopped.

Coincidence? You be the judge. smile

Still, I needed a nudge because although I generally hate change and expect it to be for the worse, I have to admit that I'm much happier with Infinity.

The engineer arrived when he was supposed to and when the modem wouldn't sync he tinkered with the green box outside (cabinet?) in the pouring rain until it did.

He didn't even suggest installing the useless McAfee junk on BT's CD and generally did a fine job.

I gave him £10 for his trouble.

I have the very same problem.

How very cynical smile

Everyone can understand people being suspicous but there could be less neferious reasons why your speed as gone down.

I'm asuming from your post that Infinity is enable from your cab?

If so this means your d-side cable route may now be more heavily populated with with ADSL and VDSL frequencies. This will lead to more crosstalk due to the phenominominominon wink known as cable fill, which means lower snr (not just margin but actual snr), and therefore lower synch speed.

The problem may be two-fold:
1. Infinity may be popular in your area and so there may have been an increase in subscribers
2. The output power on the FTTC cab should be choked back and shaped but theoretically it could still be high enough to cause crosstalk problems, e.g. your attenuation is 52dB so your MSAN's output power might be 20dBm for example, whereas the FTTC might only broadcast at 5dBm, but because your siganl has come all the way from the exchange , which might be 45dB awayfrom the cab, then your heavily attenuated 20dBm has to compete with an effectively unattenuated 5dBm.

Does that make sense? I hope so because I'm going to struggle to clarify that one!

Of course you could be correct and they might be forcing you to move to Infinity but on principal I'm uncertain smile
