Major problems, high resistance fault??

Hi all,

Over the past couple of days I've had a very unstable connection & also crackling on the line but only when the router is connected, disconnect that & the phone line is silent during the quiet line test. I've tried 3 different routers, different filters, connected just the router to the master socket (old style one with no test socket) with no phones & still routerstats shows the upstream snr varying wildly while the downstream has just slight fluctuations, also the upstream snr shows spikes upto 100db, bogus reading or indication of a very strange fault somewhere?

Also around midday today I had a situation where picking up any of the 3 phones in the house and making a call would cause the router to drop connection, now I know that screams faulty filter but just a few minutes later I went round all the phones again dialing out & this time the router didn't lose sync at all.

The crackling on the phone with the router connected is intermittent, varying in how bad it is, having contacted my isp (be*) all they've done so far is up the target snr, not happy with that support at all as that wont help with the crackling phone line issues!

Still I'm no expert but after spending all day tyring to search online with a connection that's constantly dropping, the one phrase I keep comming across for the kind of problems I'm getting is `high resistance fault`, does it sound like I have that problem with my line.

Any help would be appreciated, right now I have a pretty useless internet connection :/

Well, what you've described is a classic HR fault, but if it only appears when the router is connected, then I'm afraid you do need to get Be* to get an ADSL engineer out to your premises. Although HR faults are caused initially by water ingress into cable joints, they actually become worse when the joint dries out again. So now that we're seeing the end of a very wet spell, we will be seeing a spate of HR problems in the coming months.

It's a common mistake to atribute that to an HR fault, but it isn't. A symptom of an HR fault is that the connection only works when a phone is off-hook.

You don't have that problem. Your fault is usually poor wiring on your side and if BT find that fault the call will be chargeable. However, given the noise on the line it may be a BT wiring problem in which case you may not have to pay.

You need to get your ISP to raise the fault with BT if you can't find a problem with your own wiring.

You are wrong there. HR faults can cause either, only working when off-hook, or going off hook causes a drop in sync, or in fact neither .......

Did you make a New Year resolution to argue with every post on here, even when proving your claim means that you are talking out of your backside ? HR joints can vary in both their seriousness and the symptoms they cause, and what the OP is seeing is a classic HR joint problem.

The bit highlighed in bold is what I'm having trouble getting Be* to realise, they've already monitored my line for 24 hours which found nothing & now they want to monitor it again for another 24 hours with me on interleaved instead of fastpath....like being on either has anything to do with crackling/scratching noises on the phone line while having an active adsl connection!

That's disappointing to hear - I'd hoped that Be* would be better than that. You may have to play things their way for a while. The problem won't get any better, and sooner or later they will have to pass it over to BT Openreach (then just hope you get a guy that's on the ball !).

That sounds quite usual, good ISP, but when faced with an issue like this they seem to faf about, smoke and mirrors, rather than do the obvious thing and stump up for an LLU SFI visit ........ the strange thing is, if you are right, then neither you nor BE would pay for the repair......

I have a similar noise on line when router connected to exchange only, have had this for around 4mths now, i recently have changed router to one that uses the same chipset as the isp's kit in the exchange, this fault noise disappeared for a while (1week) but has now returned again, and within the last 24 hrs it has lost connection twice ,re-syncing at a lower speed, but after a re-boot back to normal speed again, they too didn't want to raise it as a fault with bt for sfi visit,
but saying that i should ring bt as it is a pstn fault,lol and we know what bt would say,and do don't we ,
my isp too raised the target snrm twice and put me on interleave but it still dropped out, so i got them to put it back on fast and after i regraded to 16mb,

Its times like these i feel like selling the pc, and cancelling this don't work properly broadband and phone

I'm 99% sure it's not a pstn fault though, it's an adsl fault surely just like what I'm suffering with, it's a router obtaining a sync to the exchange that starts the crackling/scratching noise & said noise goes away a few seconds after the router sync is gone & because the noise doesn't stop the moment the router is taken out of the equation means it's not a router issue, at least not in my case as I've tried 3 different ones just to be absolutely sure anyway.
