Above taken from my DG834G V1 router

Have been having trouble with router not syncing as it used to(always used to synch ds @6DB now it is @12db)
anyway i contacted Enta support and was told that before they would ask BT to lower the db on my line back to 6db the error problem would have to be sorted first.But if it was the fault of my hardware or internal wiring iwould have to pay around £160.
Too near to xmas for this so i have posponed making the decsision untill the new year
Does anything in my quote mean anything usefull to the pros here?

I have connected the router to the test soket with no additional devices and while the errors were less that above they were still there:)
 
CRC errors are never good. If it'd been FECs and your were interleaved I'd have said ignore it - my ADSL used to clock up 16k FECs a second but as it's not.....

You say you tried in the test socket - was that with or without the filter/splitter??
If so, have you tried another and/or without it in line as it MAY be one that's on it's way out.
 
Tried without any filters,direct to the socket
Socket is a nte5 type built in filter when in normal use,but i have tried with normal ordinary filters too all seem to give errors
Does it `look` like an external problem?
If it is fine tomorrow gonna get the ladders out and check the last thing i can ,where the cable enters the house gable end there is a junction box(pretty high up and steep ladder positioning too :(
 
How long has that connection been up? The CRC rate is tiny, so I don't see how they can say much about it...
 
It was up for a few hours only when i took that info.They tested the line a few days ago iirc it had been up then for around 200+ hours

here is one from today been up now for 16.5 hours
Looks like i will have to chance the extortionate engineer callout after xmas :(
Although the line speed has risen nearly back to my usual of around 2meg
 
I really wouldnt waste your cash. 840 CRCs in 16-17 hours isn't that bad at all. I've seen Leased lines doing 100 times that rate that stay syncd up.
IF you have a ring wire in the socket, remove it. That'll reduce a bit of noise but to me those error rates seem fairly normal for a standard BT phone line.
If anything the errors are a symptom of a desync/line issue not a cause.

You could try a different router/cables see if that helps.

Out of interest what service are you on? ADSL max?(8meg)
 
Am on UKFSN ADSL MAX but only scrape a profile of 2000 although last month i had a diff router and was able to tweak to a profile of 2500
Only reason i was considering an engineer call out was because Enta told me they could not get my snr lowered back to what it used to be because there are errors on the line
I just don`t see why not.for years the snr has been 6 now it has been changed to 12 and the line speed has correspondingly gone down :(
Have got another netgear router which i did try yesterday but was still getting errors too(is a small amount of errors normal?)
 
In certain scenarios yes a small amount of errors is normal.
Given you're on ADSL max and scraping 2meg it's clear your line is either long or of poor quality so i'd expect to see some errors on it.
The reason your profile was upped to 12dB is most likely due to a ver variable SNR margin or perhaps just the quality of your line. it's not uncommon for BT and other LL providers to alter a profile to "optimise" it for reliabilty over speed.
Best thing you can do is maybe invest in the Router that got you up to 2.5meg as that'll probably get you back up to 2meg.
Tbh BT are unlikely to change the profile even if you ask so you're probably better off trying to work around it.

Well actually i asked Enta to get BT to reset my SNR back to 6 after BT raised it about 6 months ago and they did
Then about a 6 weeks ago i got a secondhand DG834GT router and was using the DGTEAM firmware to give me a lower SNR(This died on me about 2 weeks ago)Am wondering if `playing` with the settings in that router made BT raise the SNR?
ADSL Connection Status

Your connection is currently on
Current Run Mode: Interleaved (FAST or INTERLEAVED)
Interleaving Opt In: Unable to determine current interleaving status (YES, NO or AUTO)
Current IP/BRAS Profile?: adsl1500-b
Click to expand...
Above is my current status
I think i may get a new GT router in the new year to try for a better connection

Just got off the ladders the connection where it enters the house looks fine :( no water or loose joints so the problem is not on the house end:)
 
Certainly the ailing router or switching the router could have caused some resyncs etc which could have caused BT to up the target margin.
If you've had it done before and they've put it back it's not that likely they'll do it again. Least not without charging you.

Surely it is only a case of click click on their computer and job done,surely in this day they don`t need to send a bloke into the exchange?
 
Yeah it is pretty much that. But they have to log everything they do, and that person costs money and it's BT. Thus if they don't have to do it, they won't.
