Still getting the odd re-sync

PuncH · Jan 15, 2010, 14:47:35

Hi

Things seem to be settling down now in PuncH towers, however I'm still getting the occassional re-sync and my line is sync'd at around 3000kbps less than it used to be.

Had a re-sync this morning after the connection had been up for over 36 hours, and then line came back up at the same speed and margin.

Is this something I should keep an eye on bearing in mind my connection used to stay up for months at a time without any problems, up until about 3 weeks ago (start of the P'boro BRAS debacle).

I have a new filter and twisted pair phone cable from ADSLNation so pretty sure I can rule that out. Also, there are no extensions hard wired off my master socket so only other culprit indoors would be my router.

Rik · Jan 15, 2010, 14:48:39

Could you try a different router, Jonathan?

PuncH · Jan 15, 2010, 14:55:41

Hi Rik,

Sadly I can't. Don't have a spare and I'm not really in a position to buy a new one at the moment. Especially when there may be nothing wrong with my current one.

Rik · Jan 15, 2010, 14:56:52

In that case, talk to support and they can test your line for you.

PuncH · Jan 15, 2010, 14:57:42

They did run a test yesterday and found no faults

Rik · Jan 15, 2010, 15:05:01

The line may have degraded then, it happens all the time, especially when there's been cold or wet weather about. You may have to wait for spring to see an upturn, or it could be permanent. Unfortunately, BT will do nothing about such degradation.

Have you tried a quiet line test, 17070 option 2?

My 'loaner' router is out at present, but I can let you know when it's back if you want to try it.

PuncH · Jan 15, 2010, 18:45:55

Thanks Rik, will bear that in mind.

The fact that some damp may have got in somewhere along the line had crossed my mind, so I'll see how it goes as things (hopefully) dry out.

I've also exchanged a couple of emails with support and they are happy my connection is behaving normally. In fact they said that ADSL2+ lines rarely go all that long without a re-sync as the DLM gets info about the connection every day and even the smallest adjustment will prompt a re-sync.

I did find this a little odd bearing in mind up until 3 weeks ago my connection would stay up for several weeks at a time.

Anyway, support reckon it's fine so I'll go with it and see how it goes.

Rik · Jan 15, 2010, 18:48:32

Your experience and mine are the same, Jonathan. I went six weeks without a re-sync, then over a couple of days DLM raised my NM by 6db and triggered 5 resyncs.

PuncH · Jan 16, 2010, 11:36:35

Had another re-sync this morning

Margin up by 6db and sync speed down by 4000kbps in one go!

I wonder if BT's green box has got a bit damp inside? Or even where my line enters my house? There doesn't appear to be a protective box over the point it enters the house.

adamr8965 · Jan 16, 2010, 11:47:42

punch i got a netgear router from idnet that i didnt need as i have a range max router u could borrow or purchase if u like? Might help your problem

Rik · Jan 16, 2010, 11:50:15

Talk to support on Monday, Jonathan, ideally email them a photo of that box.

PuncH · Jan 17, 2010, 09:22:18

Hi guys,

Adam...thanks for the offer, will bear that in mind.

Rik...I popped an email off to support yesterday so will see what they say. With all the snow and rain we've had lately, I wouldn't be surprised if the damp is affecting my connection either at the point of entry to my house (although I've checked the neighbours and theirs are the same) or the street box across the road.

Do you think it's worth me raising a voice fault with BT and get them to swap me onto another pair to the exchange?

Rik · Jan 17, 2010, 09:42:17

Only if you can demonstrate a voice fault, Jonathan.

PuncH · Jan 17, 2010, 09:50:12

Hmmm...short of rustling a crisp packet while I'm on the phone to BT I can't really

Rik · Jan 17, 2010, 09:52:04

You could try suggesting that you can hear other people's conversations faintly. That's reputed to work.

PuncH · Jan 17, 2010, 09:54:36

What are the errors that DLM would look out for? Is it sever errored seconds or similar?

My line just dropped again but I've only seen a slight decrease in speed this time. These are the stats from Routerstats:-

Rik · Jan 17, 2010, 10:00:56

Afaik, it looks at errored seconds and CRCs, Jonathan. You have quite a few for 30 minutes of uptime.

PuncH · Jan 17, 2010, 10:08:55

Bum

Cheers Rik. I wonder if a high error count could be caused by damp? Might just have to ride it out and see if things improve as things dry out!

I just find the whole episode incredibly frustrating as my line was so stable only 3 weeks ago.

Rik · Jan 17, 2010, 10:09:39

You should have seen my line last summer - 1.5M more than now.

PuncH · Jan 18, 2010, 21:49:03

Spoke to support today.

Need to do a speed test from the test socket and send them result. They also suggested moving all electrical equipment away from the router. The only thing nearby is the base unit for my DEC phone which I'll move tomorrow once I have a long enough telephone cable!

Sync did drop this morning, but downstream wasn't affected. It was the upstream that decreased (seen this once before).

PuncH · Jan 19, 2010, 12:46:28

Spoke to Brian at length this morning.

Looks like I've got a long drawn out period of testing in front of me.

I plugged into the test socket last night and will leave the router plugged in there for a few days and see if things stabalise. I also removed my Sky+ box from the phone line. If things settle down then it's either the Sky+ box or I have a faulty faceplate on the mastersocket. If they don't settle down then it could be my Dec phone which is using the electrical socket next to my routers, or I have a duff router.

If it's none of them then I'm stuffed and stuck with a line that can't seem to make it's mind up about what speed to sync at!

My line re-sync'd again this morning, but of course I doubt the fact that I'm on the test socket will be seen by the DLM will be seen until tomorrow morning. So fingers crossed it won't drop tomorrow.

One thing I did see this morning after being on the test socket for approx 9 hours, was a very very low error count. There was just 1 CRC and 1 errored second which is much much better than the stats posted earlier in this thread!

Keeping my fingers crossed!

Simon · Jan 19, 2010, 13:18:35

As are we.

Steve · Jan 19, 2010, 14:05:13

Sounds encouraging if you've managed to reduce the error count

Glenn · Jan 19, 2010, 14:17:33

If the error count has reduced when fitted to the test socket, is the problem in the house?

PuncH · Jan 19, 2010, 14:33:52

I think it could be in the house. I have no extensions hardwired off the master socket so that's out of the equation.

At the moment it's either the Sky+ box I unplugged from the phoneline last night, or the faceplate itself. If it's neither of those I will then look at my nearby DEC basestation or the router itself!
