Hi

My  last posted    :Your last synch rate Downstream 3,424 Kbps will get you a profile of 3000Kbps . 


your quote today :  IP profile pans out at 2500, in line with everything else.

Have you rebooted or had a resynch since your  last posted set of stats ? if not then you should see your profile go up to 3000Kbps .
That of course will only improve your throughput during  "Good" periods ,that is if you have any .
Regards Jeff :)

It'll ping at anything between 41 and 60 ms

That ping's ok

consistantly over 80ms is a bit tetchy, >130ms could be a problem although on a typical test the odd line at this speed is typical and isn't a problem

Sorry Jeff missed your post, yea I reset hub couple of days back, as apparently I'm told my line is "retraining".....hmmm

stats as follows:

Connection information
Line state Connected
Connection time 2 days, 23:09:55
Downstream 3,584 Kbps
Upstream 448 Kbps


ADSL settings
VPI/VCI 0/38
Type PPPoA
Modulation ITU-T G.992.1
Latency type Interleaved
Noise margin (Down/Up) 6.3 dB / 18.0 dB
Line attenuation (Down/Up) 56.0 dB / 31.5 dB
Output power (Down/Up) 18.2 dBm / 11.9 dBm

BT tester is seeing IP 2500 for these stats, but dont know whether they've fixed my SNR? ::)
I get good speed sometimes, but then it chokes down to 200k or less very quickly, as if someone pulls a switch???? :o

Have you noticed any correlation between the time of day and the throughput speeds that you are achieving?

Hi

 
Quote : BT tester is seeing IP 2500 for these stats, but dont know whether they've fixed my SNR?

your  SNR margin : Noise margin (Down/Up) 6.3 dB / 18.0 dB   .

That seems absolutely normal .What do you think needs fixing ?


Your profile should go to 3000Kbps shortly (give it a couple of days )  . IF you do not resynch at a lower rate .

As for the throughput that is another matter .

Regards Jeff

Hi Jeff

When I say fixed my SNR. I mean fix as in they've locked it, as I believe they can?
But tonight SNR had dropped to 4.1, and yes IP profile has increased to 3000; so perhaps they didn't lock it.
But tonight during peak time download/ throughput (really) was well down to below 200kbps.
In fact at one point fell to 13kbps, at which time I used the BT tester, because I'm told they can trace the tests from the BT tester.(by support)
During the day I was getting well over 2000kbps.
And also made a point of reminding them that 13kbps fell way below the levels to meet terms and conditions.(600kbps min)   >:D
Allegedly this latest "training period" ends on the 18thDec.
I've towed the line and just them get on and fix it up till now, after the 18th if it aint fixed, they'll know more about me!

Hi

Quote : Allegedly this latest "training period" ends on the 18thDec.

The training period should not affect your throughput . It basically establishes the LINE  condition and tries to find the opotimum conditons for your line  see link below for a fuller description.

why the latest training period .(did I miss something)

Hi Jeff
Well since the start of my problems, "some work", whatever that is, was done on my connection, and apparently it was put into training for a second time, that's all I know apart from it changing from fast to interleaved...but I've been constantly in touch with support and another Openreach engineer visited on Friday to perform a pairs test on my line, and found absolutely nothing wrong with it. He also checked the card at the exchange and found nowt also, he then rang me to say he was contacting BTw to get a lift and shift carried out, as clearly my line has trained, synched and settled but throughput is chronic in the afternoons particularly.
He also stated that my exchange was "well known" for throughput issues... :( not a good sign, I was hopeful when I heard about having a lift and shift...but now?
Lift it from a bad card to another bad one?  I can feel another disappointment coming on..

Hi
Have tried to log your slow throughput as suggested by Orainsear?

No Jeff I didn't (appologies to orainsear , for missing your post) :-[
However for the past two days my bandwidth throughput has improved dramatically, getting a good 2 megs connection at most times. :)
Whether it's because there's more bandwidth available owing to people being at home and businesses are not using bandwidth, dunno.
But during my last comms with support they inferred an engineer who visited me (openreach) had allegedly found an alarm at the exchange, apparently on a fibre connecting our exchange to a bigger one in Scunny.  8)
Things did seem to get better from 11 a.m Crimbo morning onwards, although find it hard to believe Wholesale bods worked Xmas morning!!!
Fingers crossed things are better atm.

Got a few errors on stats, but hey.....opinions welcome,,

>>> Got a few errors on stats, but hey.....opinions welcome,,


Its normal to see FEC errors if interleaving is switched on..  its just a sign that interleaving (and error correction) is doing what its supposed to - so I wouldnt be concerned about thost.

The strange figure on the CRCs is a known reporting issue on some routers so should be ignored.
Aside from that.. the rest are minimal and perfectly normal.

Thx Kitz...and thx to all those with advice.
Well it's day 5 of a good connection atm, so not tempting providence with any synical remarks!
We;re pretty good, perhaps they fixed said fibre after all.   ;D

Nope!! :no:

Back to square one, but apparently BTw have concluded that there are 18 people in my area with a bandwidth throughput problem, and the Proactive Care Team are on the case, Doh!
Well I've connected my Netgear DG834GT thinking perhaps it'll give the line some stability, coz it reset back to interleaved from fast connection, and my IP profile did go up to 4000!!!..but it's back down to 3500 with so:

ADSL Firmware Version A2pB022c.d20e
Modem Status Connected
DownStream Connection Speed 3648 kbps
UpStream Connection Speed 448 kbps
VPI 0
VCI 38

I telnetted the router to check the stats, follows:
