Used to sync for roughly three years 8meg/448kbit... as of today it won't go any higher than what you see in the bold text.

What's happened?
 
Yup. I phoned them within half an hour of realising there was a problem. But they said the fault has to last 3 hours in order for them to "flag it".
 
While you're waiting do a BT fault check too just to be sure, you can do them via the 151 faults dept number. Also check the line history for the last few days... have there been an inordinate number of disconnections that may have caused your profile to plummet?

Which ISP are you with by the way?
 
Nildram

I phoned them again and got through to a foreign guy but he was awesome and said his line check couldn't run because the line was engaged. Odd. So I picked up the house phone and nope - no dial tone. Picked it up a few more times and then I got a SIREN type sound coming down the line.

He recommended I call BT.

Called BT and they're saying there is an exchange fault.

Estimated response time: tomorrow

LAME! :rolleyes:
 
NathanE I know this isn't related to your problem but I really suggest thinking about getting O2 broadband... £12.50 a month and it is rock stable and should be very fast on your line if you're currently synching at 8MB on MAX. ADSL2+ is just so much better, and the price is a killer. :)
 
I just picked the phone up again and there is an awful awful siren sound. It's like there is about 10 concurrent WW2 air raid sirens running at 10x the normal speed.

I don't think my exchange has ADSL2 yet so don't think O2 would be that great for me?
 
If you've got a voice fault, reporting it with BT should get you a faster fix - tomorrow sounds pretty crap if you're left without a working phone...
 
I think that when the siren thing starts on the line it knocks the ADSL out and it then resyncs at a stupidly low rate.

When the siren isn't there the ADSL seems to sync not too bad (currently 7meg but still not my usual) and is generally fairly stable.

I think what's happened is some silly BT engineer has plugged my line into someone elses house, or in some way got the wires crossed.

My house phone has an icon showing that indicates there is another phone picked up in the house. When there isn't any other phone in the house!

PS it was BT that gave me the ETA of tomorrow.
 
Well they've "fixed" the voice line now and my ADSL is stable again. But it no longer wants to sync at 8meg. Currently it's at 7616 kbit/s and 448 kbit/s.

I guess they've moved my line onto another twisted pair that isn't as good as my last one?

Here is what my router says:

Code: 
DSL Flavour = ADSL over POTS  
    Reserved Bandwidth (kbit/s) up/down = 448 / 7616  
    Uptime = 00:05:08  
    kBytes Tx/Rx = 2256 / 1212  
 
       Properties 
      Output Power (dBm) up/down = 12.0 / 19.5  
      Attenuation (dB) up/down = 15.0 / 24.0  
      Noise Margin (dB) up/down = 25.0 / 11.5  
      Vendor Id (local/remote) = ALCB / ALCB

Are those noise margins etc OK?
 
Well actually it used to sync at 86xx something. So technically about a megabit down...

Yes I guess it is splitting hairs, afterall DSL Max only guarantees 2Mbit. But still. If you had 8meg running fine for like 2 years and then all of a sudden your line gets screwed up and as part of the fix they put you on a crapper twisted pair. You'd probably feel a bit miffed as well :p

Maybe I'm being paranoid. I never used to monitor my sync rate before to be honest. So maybe it has gone to these speed a few times before without my realising. Maybe the hot weather at the moment has something to do with it.
 
It could take upto 2 weeks before your line sinks again at 8128, they have set your noise margin higher, and when the system thinks you are stable again, the margin will decrease, allowing a higher sink speed. DO NOT keep rebooting your router, because this will give Bt's system the idea that your line is unstable, and the 7616 will drop again.

OK thanks. I thought it might be something like that. I have rebooted my router about 4 times today... I better stop that compulsion now :p

O2, or bethere (they're the same) do an 8MB service though, which isn't adsl 2 :), I'd highly reccomend them myself, epecially when your exchange is upgraded to ADSL 2. I've got Be's 24MB service, I USED to get 23.5MB, but I "only" get 22.5 now (since changing routers) :D. I'm gonna be getting a better router soon, so I hope my speed goes back up :D. I live almost on top of the exchange, it's about 40-50m from my front door ;)

The 8Mb service is ADSL2+, I'm on it.
 
You can limit the maximum downstream sync rate with either ADSL or ADSL2+, and ADSL2+ is backwards compatible with ADSL.
 
ADSL2+ can run at 8Mb, and this is what Be and O2s service uses. I'm not disputing the fact that standard ADSL can also do 8Mb.
