ADSL MAX giving me speeds of 200kbps, advice please

I recently got ADSL for the first time (I used to have 4Mb ntl cable which worked perfectly but ntl themselves were a nightmare so I thought I'd have a change) - I am on the MAX service with Freedom 2 Surf. One of the reasons I chose them is that I can quit after three months if I want to, without having to pay any installation/cancellation fee.

Anyway, the first time I connected I got a line speed of nearly 3Mbps and was able to download from a few speed-checking websites at about 2.5Mbps. Not too bad I thought, bearing in mind I know that with MAX your line is monitored and speeds can change in the first ten days etc.

On subsequent days although my line speed remained approximately the same, my speeds dropped to 900-950kbps - suggesting I was capped at 1Mbps perhaps.

For the last couple of days my speeds have been capped at little over 200kbps, although my line speed is over ten times that :rolleyes: What possible reason can there be for this?

Another big problem I am having is, my connection drops in the evening and will not work again until the morning. This is because the SNR margin is dropping below 6, and goes as low as 1 or 2. Also my line speed drops to around 1700 at this time. Sometimes you can connect at this period for a minute or so, but with tonnes of CRC errors and almost impossible to connect to any website. Yet during the day the connection is rock solid and stays up for 12+ hours.

I emailed F2S technical support about this and they didn't bother to reply which was nice of them. I rang up yesterday (which I was loathe to do as you have to pay 0870 rates and then wait in a queue for ages) to ask if he could get BT to increase the SNR margin on my line to improve reliability etc. He told me that things should improve after Sunday, when I will have been with them for ten days. He agreed that the loss of service at night is not right and said I should ring back if it is no better next week.

Incidentally I am connected directly to the BT master socket, and when I tried connecting to the BT 'test' socket behind the front panel, things did not improve at all so I assume the socket is okay.

Can anyone offer any words of wisdom on my situation please ;)

I was in exactly the same situation as BT's default SN/R margin of 6 dB wasn't enough in the evenings.

I asked my ISP (Zen) to request that BT increase it to 9 dB and now my connection is a lot more stable with it not dropping below 5.5 dB though this means that I get a slightly lower sync but I prefer a stable line.

That's probably due to the falling noise margin and the same thing used to happen to me.

Also have you got interleaving enabled as that helps with the errors as I'm sure you already know :)

Again, I used to get that as well and it is because the noise margin is at it's highest through the day.

I bet you wished you had never left NTL now as you didn't have these problems before :p
 
Interleaving is indeed enabled :) And yeah moving from ntl isn't looking too clever at this point :o

Well I'll ring F2S again early next week if things don't improve on their own. I just hope that they will give me a sensible speed, ie. at least 1Mbps and not the current 200k which is basically atrocious. Then after the three months is up I think I'll ditch them and go back to ntl.

Can BT not see that my line is dropping every night and increase the SNR margin themselves, without needing to be asked?! Also can they not see that I am syncing at nearly 3Mbps, so why don't they automatically increase my data rate? Meh.

I know every line is different but that never worked for me as although my line was unstable, it never got so unstable as to trigger BT's DLM into action as AFAIK your connection needs to drop 10 times within an hour.
My line used to drop 3 or 4 times a day which wasn't frequent enough.

I don't know if BT actually monitors people's lines to this extent as it would be too time consuming but yes the DLM should sort out the connection drops but unless your line drops 10 times (as mentioned above) then your noise margin won't be increased.

Also I don't know if you can 'fool' the DLM into increasing the noise margin by manually disconnecting the router the required amount of times?
I wouldn't know as I didn't try it and asked my ISP to sort it out for me instead as I wasn't sure of the consequences of doing this.
 
Tolien, are you around? I would appreciate your input into this as I'm sure you know the answer :)

(apart from binning this crap and going back to cable)
 
Putting you off till the 10 days are up is not a lot more than a delaying tactic.

What possible reason can there be for this?

  • Congestion (expect an improvement at "off peak" times)
  • Packet loss as a result of cell errors (you'd see error rates going through the roof)
  • Sustained low sync rate resulting in a reduced BRAS rate (probable, given low SNR margin at night is going to result in a reduced sync rate)

BTw will be "monitoring the line" with the DLM kit (or else interleaving would never have been enabled), but it's (as you're seeing) not perfect.
 
Well I seem to have been on a BRAS profile of 256kbps for the last few days, despite always syncing even at night, well over 1000kbps (usually 1700).

This morning I have no service whatsoever - which has never happened before, it's like there is no ADSL signal on the line. At night it would at least give a sync speed and SNR figures, before disconnecting 20 seconds to a few minutes later. Today, not a sausage.

I wonder if this is something to do with the ten days being up? Yesterday was the tenth day. I'm currently connecting via dial-up, not that there's much difference in speed between this and the 'broadband' recently...
 
It's working now, syncing at 1088 and a data rate of 960... lovely. Still capped to 256kbps though.

Oh and the SNR margin is now 20-21, never been that high before. Surely I should be on at least 512kbps though. Ho hum.

I will re-connect in a while and see if it improves...

Okay now syncing at 2464, data rate 2240, SNR margin 9. Still capped @ 256.

come back to the ntl cable fold :) :)


theres some juicy speed increases on the cards over the next few months
 
phone ntl sales and say your thinking of coming back what can they offer :)


btw 1 meg is increasing to 2 meg in sept and theres something hush hush happening with 10 meg by xmas :)
