line sync speed stuck

Hi...

I have a problem as where the sync speed on my new install is stuck at 128 down and 64 up..

been like this for 5 days now.. tried calling BT but the offshore call centres just say that i have broadband and they cant find a fault after line tests.. cant seem to find anyone in the uk willing to deal with it, all i get is we will transfer you to technical, but thats again overseas....

can anyone think of a way to get this resloved

Can you see if you can get the line stats from the Hub? See here for help in finding them.

They will tell us what speed your line should connect at, and possibly give a clue as to the cause of the problem.

Is this your first broadband connection in the UK, and if not, who were you with before and what did you get?

i have had broadband in the uk for quite a few years.. different isps at different addresses..

this connection was meant to be a line and adsl transfer but BT messed that up.. so its a new install at my new address, its been at the current Sync speed since it was activated last wednesday( actually activated 5 days early) i have tried 2 different home hubs(1.5 and 2) and also a belkin router, all same results, the availability checker say upto 6.6meg available...

the exchange is actually just up the road from me, about 500 yards..

line stats as follows
Downstream 128 Kbps
Upstream 64 Kbps

Noise margin (Down/Up) 30.3 dB / 31.0 dB
Line attenuation (Down/Up) 9.0 dB / 6.5 dB
Output power (Down/Up) 2.9 dBm / 2.7 dBm
Loss of Framing (Local) 0
Loss of Signal (Local) 0
Loss of Power (Local) 0
FEC Errors (Down/Up) 0 / 0
CRC Errors (Down/Up) 0 / 2147480001
HEC Errors (Down/Up) 0 / 0
Error Seconds (Local) 0

I'm no expert on BT Call Centres I'm afraid, but those stats are complete garbage.

Noise Margins over 30dB, attenuation in line with what you say the distance is (I think), very low power levels.

The thing is you should now be able to quote or send those stats to support and perhaps get up to higher levels than the phone answerer.

A BT Speed test - www.speedtester.bt.com - result could be useful to them as well.

If you have another modem/router from your earlier connections it may be worth seeing iof you can get one to work. Maybe your new Hub is duff? Have you swapped filters as well, and tried the BT test socket, on the wall at the back in this pic?

No way should you be getting more than single digit per day errors at that noise margin. Try resetting the router and see if they are building up at a constant rate or in bursts.

i have tried, the home hub 2, and a homehub 1.5 and a belkin router. all give the same up and down sync speeds, the homehub 2 was working fine 2 weeks ago at my previous address.

already tried different filters and also tried using the test socket..., No extansions at all in this house and i made sure that no phones are connected either

i have done everything i can think off.. i may just have to try calling support again and ask to speak to a manager..

i actually got thru to someone in the UK this morning and was told it wasn't her problem and she then passed me thru to india again....

reboot the router and post the figures again after 20-30 minutes or so - that CRC error reading looks like it could possibly be a firmware bug rather than a real reading.

I would also suggest replacing/swapping microfilters if you have spares to hand.

BT help desk ONLY exist to fob you off and send you around in circles until you get bored and give up. If you want to make real progress then unfortunatly you'll either need to get the attention of one of the BT web team or approach ian livingstone directly so he can get his ELC or HLC team onto it

ah hah

well i got home tonight and its now synced at 8128 and 448, done a speedtest at speedtester.bt.com and my ip profile is at 2000, so rang up again and told to wait and see what happens, somehow i dont think waiting gonna make much difference as i think its a stuck profile now..............

will update when i get more info............

Well the sync speed is great news .

What makes you think it is now a stuck profile? It looks to me like the original connection was totally screwed, (or maybe not screwed if you get my point), and you now have a proper ADSL Max link.

The profile often or always starts at 2000kbps these days then self-adjusts according to the normal rules. See this table and the explanations above and below it. So you probably have one or two days to wait, though it could be up to 5 days. Maybe just overnight.

What you do need to find out is whether the 10-day training has restarted. This is quite important as all the training period really does that is set in stone is find your Maximum Stable rate, which seems to be the lowest sync you get in the period.

From the MSR the Fault Tolerance rate is set, at 70% of MSR.

In the future if your sync falls a lot, so long as it is above the FTR then BT just say tough! Only if it is consistently below the FTR will they accept a report of that and accept it could need investigating. (Not necessarily a fault).

If those early sync's are retained on the records then in respect of the FTR you are permanently stuffed.
