Back to IDNET, but something's gone wrong...?

I would agree Paul that big upward differences between IP profile and sync occur relatively quickly and then slow as the sync is approached.

I'm only 3 days in, and I appreciate its late but this is starting to bug me. Here I am logged in via my phone because the ADSL link has been down for about an hour and a half now. I re-started the router a few times, nothing. Tried another router and also nothing. Then thought to check the dial tone on the landline. Can you guess what the result of that was too :-/

Line faults, pffffft what a joke - it appears dead :-(

Router logs filling up with loads of error lines:
User - Critical - Kernel: xDSL G994 Training
User - Critical - Kernel: ADSL link down
(repeat)

I will check again in the morning, but anyone had this happpen before??? :-/

Phone support first thing in the morning, they will get it sorted.

Apparently not. I don't thnk im getting any broadband over this weekend (Line's still down, support are "investigating")... :-/

Which most likely means its in the hands of BT.. hopefully something comes back as faulty or you will be going around in circles

I know what's it like to be without a connection over the weekend, when I got upgraded to the 80/20 FTTC trials, my modem failed to reconnect when BT pushed the button on a friday morning. Took over 4 days to get an engineer here to replace the faulty modem they supplied

pctech · May 18, 2012, 20:50:30

You maybe lucky, if multiple people from different ISPs report a problem on your exchange they may send an engineer to have a look over the weekend but if its just you it won't be fixed till next week.

RCS2K4 · May 24, 2012, 11:12:11

It's been nearly a week since I last posted, and after a period of stability from late Saturday to Tuesday, the speed has fallen significantly from Tuesday onwards.

Over the weekend, a downstream sync of 23MB was held, upstream was approx 0.7MB – The SNR was 2.5. I had good throughput of approx 21MB on speed test sites.

Today, it's back to a downstream sync of just 13MB (and has been since Tuesday), upstream is 2.4MB (AnnexM FTW) – The SNR is 14.3. The current throughput is 10.5-11MB.

Why is my sync speed up and down like a yoyo, and seemingly stuck at 13MB now? Also, is turning on AnnexM one of the main causes - I know you loose a little download speed by using it, but it's nearly cut it in half?

psp83 · May 24, 2012, 11:20:26

You may had alot of noise on the line and the equipment at the exchange put your SNR at 15..

Mine kept being put to 15 when I was on ADSL2, it's a pain in the arse.

Find out if you got anything that create noise on the line, sockets, extensions, sky, running phone cables parallel with power cables (they should cross)

Another way around it is, upgrade to FTTC if its in your area

Interesting, and based on your speed test footer you clearly don't have a bad line and must be pretty close to the exchange. (Like I am, attenuation roughly equates to line length right? That's currently 11.5Db for me, and always has been.)

Meh, I've checked that to death. I don't have any extension sockets or trailing phone cables. I've disconnected the SkyHD box from the line a week ago just to remove any possible issues with that. Everything is set-up the same as it was when I was on Sky's Broadband equipment wise, and in the same places. It held a steady 24MB sync for a year without faltering...

See, it's been installed. I've got fibre cabinets at each end of the street that they installed about 6 months ago, and they also dug up the road to lay new fibre down. I actually asked some Openreach people what they were doing at the time. Their answer was installing fibre broadband to George St. (sweet!).

However, even 6 months later BT's website says my address is not in a fibre covered area, but my neighbours house a few doors down does have it, as they took that service out some 2 months ago and it's fast (They were getting 36-37MB off it, god knows how fast it is now the speeds got a free upgrade)... :-/

I had a bad line when I was on ADSL2, 36 attenuation & 15 SNR, I could only get 6mb down and 1mb up. My line went through 2 PCP's then to the exchange.

I'm now on FTTC and had issues with the order at first because of my line going through 2 PCP's, they kept putting the order on the last PCP and took 3 attempts to get FTTC installed as they had to re-route my line.

The FTTC cab is about 500m away from the house.

Is your line underground or above? mine goes near a street light and this can cause noise issues.

It depends what PCP you are connected to and if its been FTTC enabled yet. The phone pole outside my house is fed by 2 PCP's, BTO told me I was lucky as my line goes to the one that is FTTC enabled as the other one is not going to be enabled for a while.

RCS2K4 · May 24, 2012, 20:00:36

My phoneline is underground. However I've now royally had enough and am going back to Sly's LLU

I get home from work after leaving the router another day and speeds have fallen even lower - again. Furthermore, the AnnexM I that costs extra, for whatever reason the router's no longer picking it up now (based on that upload speed - it's pathetic). The current state of play is irritating on a line so close to the bloody exchange:

IDNET's reply to my email has also given me the distinct impression that they won't be looking at it:
"BT's set the SNR at the exchange to 3. If your router is increasing this value, then it indicates a high level of noise on the line. That sync speed is the best your line will hold."

Support can't really do much about noise, Sky equipment is different to BT's, that's the issue here.

Why did you move if you had good speed on Sky?

lozcart · May 24, 2012, 22:25:28

You are losing sync speed due to your SNR magin been set higher by BT line management, you are now at 18. This can be due to noise on the line as previously mentioned or it can be raised if your line is seen as unstable due to it resyncing. This could be the router playing up, manual resets of the router or a line fault. You recently lost broadband and the phone line completely what was found to be the cause of this? If it was a line fault this could be the cause of the raised SNR.

Steve · May 24, 2012, 22:29:19

I agree. At the moment you've got a shitty line, not sure why especially since you had good performance from sky LLU . It is after all the same connection to your local exchange that you've had all along. Your downstream sync is down and your margin is high. The differences between Sky LLU and BT adsl2+ relate to IP profiles and the imposition of banded profiles which limit the max sync. You may have become banded but the sync doesn't correlate with previously published band limits, ok they may have changed the banding limits and I'm not aware.

If we can't explain the high margin by the imposition of a banded profile then it has to be down to noise. I don't necessarily buy the support kop out of the max your line can support either has you have a short line and previously demonstrated it's quality on LLU.

With regard Annex M that may pinch something from the downstream I guess.

Has anything changed in your equipment since you moved to IDNet i.e. router , cables ,filters , sockets etc?

pctech · May 25, 2012, 18:42:19

Different DLM and DSLAM kit?

Steve · May 25, 2012, 20:57:09

True or something wrong with it? Trying to look for free and easy hits first.

RCS2K4 · Jun 06, 2012, 23:39:44

To follow this up, and to demonstrate I wasn't just - ya know - moaning for the sake of moaning. I've migrated to Be and will you look at the speed test I get with them on the same line and router:

It's held that steady for 2 days, no line error's etc. Thats what I hoped IDNET would deliver, and while I don't blame IDNET for the complete speed fail I had, it does indicate something's a little off with BT's 21CN round here...?

I miss IDNET's snappyness and support guys, and consistent speeds (well, I used to get them). I may come back one day, maybe when IDNET get their own LLU. They would be the perfect ISP if BT never had to be dealt with...

Lance · Jun 07, 2012, 00:12:59

Idnet can use Be if it is installed at the exchange so it seems like you didn't need to migrate to get away from BT.

Looking at a quoted email response from IDNet it's perhaps understandable that the customer thought he had to try somewhere else especially with knowledge that the line had previous good quality on Sky LLU.
