It will do no harm to turn off the router, just don't keep doing it. More than 10 or so re-syncs in an hour is likely to trigger a downward movement on the BRAS profile.

Will it hurt to turn off the router since i am in my 10 training period ? I thought that you had to leave the router on

Happy Xmas Bill
I know your speed is sorted today, but the usual advice in the training period is reboot your router once a day.
This sends a signal to max that you can reconnect reliably at a decent speed.
Sometimes leaving it connected all the time doesn't give Max the prod it needs to set your BRAS rate properly.

And also remember that after the training period, Max will still adjust your rate as it sees fit, so it's not set in stone.

The "training period" is normally quoted only to keep you quiet for ten days while it sorts out a proper BRAS rate for you.  In your case it's done that already by the look of it, so I'd forget about it.


Rik

It's also impossible to raise a fault with BT during the training period. :(

Hi,
  As i said in one of my previous posts my rate has been set at 5000KBPS. However my speeds are still all over the place, Is this normal ? I have not yet seen a 5 meg download speed am i likely too  get that fast ?

Nerval

With a 5meg stable rate, the best you will get in practice is about 4.5 ish.  The 5 is a theoretical maximum figure only.

Actual speed is subject to so many other factors - your exchange, the network, the sites you're downloading from, etc etc.  Though unless your exchange is at red, it doesn't normally vary all that wildly.

old Bill

That would explain a lot. My exchange is red. Faster speeds during the day, then from about 4.00 onwards it slows down. Fastest speed I have seen is about 4.7 and the slowest 41.So from what you are saying that is about right. Thanks for the help and have a great new year.

Schools out and then parents arriving home from work wont help,my exchange is also red but i don't really notice , it says most people may only notice at peak periods so it looks like your exchange may be severely lacking in capacity (for want of a better description).

Don't want to rub salt in but i have just checked and I'm now getting.


Virtual paths: Green

There are currently no known capacity problems on your exchange.

The work  was supposed to be  done on the 11th so yours may also be running late.


old Bill

The work on my exchange should have been done by now. BT are getting very good at puting it back. Now due on the 29th/12. I live in hope.

Rik

Often, they do do the work on the advertised date - they just don't put in enough capacity, so the exchange goes red almost immediately. I find their planning a little lacking. :(

Well the good news is that my exchange is green. Now for the bad news at the start of the week my sync rate was 6080 kbps and my profile was 5000 kbps. Now my sync rate is still 6080kbps but having just run the BT speed test again by profile is down to 4500 kbps and my speeds are still all over the place. I have been disconnecting my router for about 30 min once a day. But apart from that I have not seen any other problems apart from the dramatic speed drops. If things carry on like this I might as well go for a cheaper option elseware.  :(

old Bill

Hi,
   As you can tell from my last post I was a bit anoyed last night. Can anyone tell me why my profile has dropped ? Is it because i have kept on unplugging it every day or is it down to the amount of errors on my line ? Is there any way of geting my profile back up to the 5000KBPS mark ? Now that my exchange is green i really want to make the most of it. My latest router stats are as follows. Thanks for any advice.  :)

Your stats as I said earlier are virtually identical with mine.
I'm on a profile of 5000, which sometimes drops to 4500, then goes back up after 3 days.  The drop will be cos you've resynched once at 5664 or less.

the answer is to reboot once a day only, and hope it connects  at higher than 5664.
Then when Max has reset your profile to 5000, hopefully after 3 days, keep your router connected.
If you have to reboot at any time, you just need to hope it reconnects at higher than 5664 which is the top limit for a profile of 4500.

I suspect that, like me, you'll end up fluctuating between 4500 and 5000 - and it won't really make that much difference to your performance.
But it's out of your hands mainly.

old Bill

Thanks for the advice. I rebooted a couple of days ago and my snyc speed was low. It is now back up to 6080 and has been connected for 1.5 days so i should see a improvement in a couple of days with a bit of luck.

What concerns me about your stats is the high number of CRC and HEC errors.

If you can put up with an extra 20-30mS on your ping times I think having interleaving turned on would help you a lot.

One point to note is that my Speedtouch does not reset the errored seconds count on a re-connection so it can be erroneously high, this may well be so on your router.
   
As a comparison here are my stats on a line 5km (or longer) with interleaving turned on and sync kept down to just above 4000kbps using DMT.

Note the high FEC errors - I think that this is the number of errors that interleaving has corrected, leaving a low CRC and HEC errors that require re-transmission.

It would probably worth your while talking to support about these error numbers.

Thanks for the advice. I tried interleaving about a month ago and it caused all sorts of problems so i think I will have to give that a miss. Will call C/S next week and have a word. ( i am sure they will be thrilled to here from me again not) ;D Poor Simon and the others must be sick of hearing my voice by now.

TimJ

Out of curiousity - what sort of problems did interleaving give you?

It "should" give a more stable connection but with the downside of higher pings and a slightly slower connection speed.

Tim.

old Bill

My conection became unstable and lousy speeds. Spoke to C/S who turned it off and things settled down again.

Rik

The speed should have dropped a little, but stability should have improved drastically. That's a slightly weird experience you have had. Have CS got BT out to you yet?

just to make you feel better and show you how it goes, I'd been keeping my router on and running happily with a profile of 5000 for a few days.

Then last night we had a brief power dip around 10pm, and this morning I found that the router had gone off and resynched at 5400, so that's the rate buggered and back to 4500 for another three days.   :laugh:  Resync in the morning is no problem, but it's always at night that the SNR margin goes right down.
Oh well, happy new year!!  :banana2:

old Bill

I rebooted the router this morning, Sync at 6180kbps. I have just run BT speed test and my profile is now back to 5000KBPS and my speeds have gone back up to 4.7. I AM HAPPY NOW. IDNET THE PERFECT ISP  :)

Rik

They always were. The shame is that BT are perfect idiots. :)

Well I lost my connection last night. I called C/S this morning and they sent it off to BT  I also told them about the amount of errors on my line and they said they would contact BT about that as well. My BB was back up and running after a couple of min. I checked my stats about 11.30 and found my snyc speed had dropped by 500kb down to 5500KBPS. I spoke to Idnets C/S to find out what was going on and they said that BT had not got back to them, and they would contact me when they had something to tell me. I had a call from BT wholesale this afternoon wanting to know how the interleaving was working. I told the person that I had not been told that interleaving was on the line. He said that Idnet were told this morning about 11.00 that the interleaving was been put on my line and to find out after a couple of hours how things were going. It was left that the guy from BT wholesale would call me tomorrow to find how my line was going. WHAT REALLY BOTHERS ME IS THAT SOMEONE IS TELLING ME PORKIES. IDNET SAY THEY HAVE NOT HEARD A THING AND BT WHOLESALE SAY IDNET WERE CONTACTED THIS MORNING. I STILL HAVE NOT HEARD A THING FROM IDNET. I really would like to know what is going on.

Nerval

Oh dear.
Can't see why IDNet would bother lying to you though.
Isn't it just that whoever BT spoke to in IDNet didn't record it, so that the IDNet person you spoke to didn't know?
Unless of course BT didn't actually ring IDNet as they said.

I've no reason to back IDNet or anybody else, just can't see that they gain anything by lying to you.

old Bill

Hi,
    I am not trying to put the blame on Idnet or BT wholesale. When i spoke to Miriam she said she would let me know as soon as she heard anything. And BT wholesale said they had told Idnet. Perhaps a mixup someware but it still does not look very good from the customers point of view. At the end of the day all I would like is a service which is reliable and as fast as possible.

Rik

What we'd all like is BT to communicate better. Like Nerval, I can't see what IDNet would gain by lying or not contacting you. OTOH, I can quite believe BT didn't get around to phoning IDNet, or they sent an email which wasn't addressed to CS. :(
