got my profile unbanded today (and yes I did send a big thanks to support). My one question is does the line go back into learning mode.
I ask as I noticed the snr was fairly stable at 6db but is now flirting between 0 and 2, with the occasional nonsense 10 digit minus figure?
No re-syncs for 11 and a half hours tho
Connection Speed 9908 kbps 1072 kbps
Line Attenuation 37 db 9.5 db
Noise Margin 6 db 5 db
There's no way it'll stay at near 10mb not at that attenuation, it's more normally around 5.5 -6mb currently bt speedtester showing thruput at 7.5mb on an ip profile at 8mb
The term learning is a misnomer as the MSAN or DLM is always managing the connections properties. I am not sure however if there is any mechanism to prevent the re banding which may occur in the presence of instability and noise
Thanks for that steve, hope I dont end up back where I've been at 135k profile.
So do we. That large number, btw, is the router showing a negative noise margin, something which technically can't happen, but which Netgears seem to do.
looking healthier after a manual re-sync this morning, as i had "internet explorer cannot find the web page"

better snr anyhoo. :red:

it's died again
Connection Speed 285 kbps 1023 kbps
Line Attenuation 36 db 9.5 db
Noise Margin 31 db 6 db
I just dont understand, It was stable at 4mb, I aked for interleaving to be switched off, it goes unstable, why can it not be reset to where it was?
I certainly cant live with this.
Is interleaving on or off now?

See my thread on 'No Broadband Internet'. Seems you are suffering the same as me - high sync = unstable then low sync = unusable. I'm trying to get back to 6meg at around 9db and stable (interleave on).
Unfortunately I am not surprised as the root cause ie your line has not changed
I understand that steve, but where does it leave me permanently slow? I've completely re-cabled with cat 6 from router to pc and xbox, new filters.
I've no idea Rik, I suspect it's still off. seems a few on here are having the same issues though. Personally I suspect it;s something to do with my initial setup, when I moved from sky. if you remember the bt engineers completely screwed up my connection. I suspect they've patched up a poor job. I'm thinking another fun mail to dan moss see if that produces the goods ::) unless he's away spending his million pound bonus
Ever wish you'd not done something! :slap:
All the time. ;)
Check with support whether it's on or off (it's too late for me to get hold of them now). Get it back on, I really don't think your line can remain stable with it off. I'm afraid you'll have to accept higher pings to get stability back.
I'll take them rik (even with it off they're still 38ms :shake: ) I'll take 'em
Repeat after me:
I must leave things alone. ;D
I've mailled support, twice, as I sent one when I 1st saw this, and another specifically asking about interleavig.
I must leave things alone,
I must leave things a......... oops :angel:
;D
very quick response fron Brian
Saying it was left on fast path so he's requested it be interleaved and unbanded should be ok in next 24 hours. :fingers:

Glad to know things are looking up Core'. I agree with the ping times. And as said, the human cannot notice such time-scales, but the programs do! Thus they stutter or crash. It may be you will have to look at different games. :dunno:
From what I've heard, MW2 is quite annoying at times, so it could save you some stress not playing on the servers. :rant2:
But on a more serious note, it may just be little more time, and tweaking to get the games and programs working. Things like port forwarding, turning off the skybox or whatever might help. I've met some little spikes in my connection recently, and it might be down to road works. Nothing IDNet can do for me in that case. :( .You've probably tried all the options, but I can only hope there is a way yet.
thanks ben. just tried re dead redemption it seems to play fine, but as said in another post it looks like BT have unbanded me again, but not switched interleaving back on
Connection Speed 9286 kbps 883 kbps
Line Attenuation 37 db 9.5 db

So Ill be back at a crawl again tomorrow
OTOH, they seem to be using noise margin to manage the line, which may give you a better result, ie speed and low pings.
hmmmm. a small wager maybe. :whistle: .
Hope so, but a 9mb profile on a 37db attenuation aint gonna hold up
I don't know, I get 4M on 57db...
ah well it's on the way out

snr falling lke a stone,
Thanks BT ! :shake:
A sync of ~9200kbps isn't bad for your attenuation.
trouble is adam, the sync wont stay, brian asked bt today to unband and switch interleaving back on, clearly they've unbanded it, but just not bothered with the interleaving.
I'm now getting the negative numbers on snr. So expect a resync very soon, and rebanding by mornnig.
BT simply cannot organise the preverbial in a brewery
Ah, indeed. I had a negative sync on the Netgear a few times and it could sometimes hold a sync. I was interleaved though. Hopefully it will get sorted soon!
well to my surprise it held up overnight but the snr is changing from 9 to 6 and back. no re-syncs tho

I wonder where that noise is coming from?
I'm going to scan all my cabling a little later on
held up for 19 hours,
settled at 9db constant now
bt speedtester, not sure of throughput tho, seems a wee bit high
Download speed achieved during the test was - 8508 Kbps
For your connection, the acceptable range of speeds is 600-8000 Kbps.
Additional Information:
Assured Rate IP profile on your line is - 8000 Kbps
:fingers:
The variations you're seeing are probably just the coming and going of noise.
Thanks Rik, after all the issues just a bit paranoid. had to down the router though as we had a big thuderstorm moving through, that droped 1mb off the speed
Runrouterstats all the time, and keep an eye on the NM. As a storm gets close, that will start to show spikes of noise. As a secondary check, visit:
http://www.isleofwightweather.co.uk/live_storm_data.htm
for a real-time picture of where storms are. If you do power down, and it is an excellent practice if the storm is close, wait at least half an hour before powering up again - the storm can continue to impact your line noise for a while.
I turned off last night. But left it on this morning. Not affecting me yet, but then I am close to the exchange, and not many posts for the bolts to hit...
More important, Ben, is the difference in earth potential at each end of the line - it's that variation on cloud to ground lightning which does all the damage. Cloud to cloud can upset the signal, but is relatively safe electrically. Get a strike at one end or other of the line and the difference in potential provides a nice big surge of current through the router and, in the worst cases, though the PC.
I had a dial-up modem taken out by a lightning strike over the house.
If you really want to live dangerously get yourself a surge protector with telecom protection.
Chocolate teapots, Mitch? :)
The one I use (A Belkin) has an unlimited connected equipment warranty so they'll replace anything thats damaged provided it was connected.
And the SP was connected directly to the mains.
Yes
