DSL not working properly since Upgrade (IOLBB+)

Ste.phen

Hey, ever since this morning my DSL has been somewhat... broken...

My current stats are as follows:
DSL Status: UP
DSL Modulation Mode: GDMT
DSL Path Mode: INTERLEAVED
Downstream Rate: 1312 Kbps
Upstream Rate: 128 Kbps
Downstream Margin: 6 db
Upstream Margin: 22 db
Downstream Line Attenuation: 63
Upstream Line Attenuation: 31
Downstream Transmit Power: 0
Upstream Transmit Power: 0


The connection is working for approx 1-2 minutes before it drops and has to be re-synched. Usually it works for no more than 30 seconds.
Repeat as required.

Basically it looks like my line cant handle the higher speeds, but it's not finding a level it's happy with, I didnt have too many problems with the 512k (it dropped sometimes but usually for no more than a few hours, and was always 512k steady).

Eh, what can I do? is anyone else experiencing this?
I'm in beaumont, 01-837XXXX, I think i'm on Coolock exchange

Thanks,
Igy

My problems are not quite as bad as yours but I also seem to have an intermittent dropping off/connection dying problem. It's not every few minutes but every half and hour or more I may be browsing or I may have some torrents going and all of a sudden I get page load errors and/or my torrents just die out
Downstream Upstream
Line Status ADSL Link Speed 2048 kbps 128 kbps
SNR 1.0 dB 0.0 dB
ATEN 52 dB 31 dB
Line Error ADSL layer FEC 0 0
CRC 2971 1
ATM layer HEC 2362 6

My SNR was 2.5dB just 10 minutes ago! I don't know what's going on but I don't think my line is up to carrying 2Mb

yea i seem to have a bb dying prob aswell when i try to load a page it gets half way then slows to a halt for 30sec.

Ive reset my router and it seems to be holding fo now.

rofl my IOL Plus connection has gone wild (56k at times speed)
and SP2 is screwed up with it now

ai ing

From Eircom: a server has died in west Dublin and has fcked up a lot of connections

Igy,

Downstream Margin: 6 db
Downstream Line Attenuation: 63
=========================================
You have a very low margin aka SNR...lots of noise for your signal...a value in the teens would help with your disconnections.
But AFAIK it is still usable

What is worrying me is your Downstream Line Attenuation at 63 db.
This is very high...actually the highest Ive seen for broadband.
At this level Broadband is very unreliable!!!

Honestly I dont think your line is stable enough to handle anything faster than 512k.
You probable just shaved the test for Broadband IMHO.

JNive

Margins/SNR less than 5dB spells syncing trouble, and attenuation greater than 50dB = dodgy, greater than 60db = f***ed :-)

diarmo

Its as simple as what JNive has said Igy.

You were damn lucky to even get approved by eircom!!!

My connection is maxing out at 50kb now, last night and this morning i had 215kb...and i'm in galway, i hope this is sorted soon

Im talking to a guy on the Tramore Exchange who is reporting "disconnects every 20mins, wild speed bursts and then sudden slow down"...

Cryos

As is said in other threads there's currently a lack of bandwidth at some major exchanges, smaller exchanges such as greystones are not effected.

Bray seems to be affected however it just seems to be pings not the acctual downloading.

Sparky

It could be due to us all testing out our speeds, we is putting a strain on the exchanges.

Actually lets blow them up with our downloading at one time thing

Lockup

I seem to get disconnected at least 2/3 times a day on IOLBB Plus. My router is showing these figures for my line quality. Are these bad?

Down Up
SNR 6.5 dB 0.0 dB
ATEN 48 dB 29 dB

Can Eircom fix this?

Lockup

Your SNR is what is more than likely causing loss of synchro with the CO.

A value of 6.5 db is the absolute minimum for synchro.
Value of above 10 db wouldbe much more acceptable.

A value of 5 db would have been an automatic failure on the eircom tests for broadband if you were interested!

AFAIK it could be faulty telco wiring in your house or possible your telephone wire length from the master socket is too long, if you are using a very long one that is.

BugBlaster

lads.
what proggie are ye using to get those dsl details?

zytel bb modem usb here.

julius

BugBlaster,

Ive typed up a good tutorial on this:

Above is from the perspective of a ZyXEL 623 user!!!

BugBlaster

finally remembered to get into the advanced settings on the Zytel modem.... dbl click the logo when holding down the shift and ctrl keys

actualBitrateFarInt= 128 kbit/s
actualBitrateFarFast= 0 kbit/s
actualBitrateNearInt= 2048 kbit/s
actualBitrateNearFast= 0 kbit/s
relCapacityOccupationUpstr= 20 %
relCapacityOccupationDnstr= 26 %
noiseMarginUpstr= 24.0 dB
noiseMarginDnstr= 26.0 dB
outputPowerDnstr= 9.0 dBm
outputPowerUpstr= 0.5 dBm
attenuationUpstr= 11.0 dB
attenuationDnstr= 17.0 dB

how do those details look??? me im no techy but i usually do not have any trouble with the connection

Hi,

BugBlaster - your numbers seem fine, you shouldn't have any problems at all.

For the people with connection problems - have any of you been on to IOL or Eircom about it? what did they say?

I'm curious to know as with most of you it's a line noise problem. This is caused by either a bad line or that you live too far away from the exchange. Eircom should fix the line, if that's possible, or you'll have your speed decreased.

RADSL - Rate Adaptive DSL. If your DSL connection was okay at 512k it should still be okay now. If not there is a problem.

julius

The Adaptive part in RADSL would be shown in your synch settings.

If your router synchs at 2048/128 then RADSL is not the cause of you only getting 1024 speeds.
