Time to SORT the network ntl

Well tonight NTL are crap

I am dropping the internet for a few secs sometimes mins but to drop the internet 11 times since 19.30...

I would like an internet connection that is reliable not one thats on the verge of falling apart.

Today my son said he was getting pings of 700+ to the server he uses all the time with his clan. This server was always 50 or below unless I was downloading or listening to a radio stream when his max was 200.

I can't see NTL surviving any upgrades like BT and Telewest with the network in such a neglected state.

Today he has pings of 700+ but normally it's "ALWAYS" 50 or below. How does this equate to the network in a neglected state?? To me (and it's what you said) it's normally fine..........

Sounds like there may be a few problems today......... I'm sure they will sort it.

Personally since getting NTL BB I have never had such a rock steady reliable internet connection.

I find it hard to believe things are as bad as you make them out to be if everybody I know that uses NTL BB have no issues with it......... and I know quite a few.....

I have been with NTL since july 2000 normally the service was rock solid recently as in the last few months its been like this then fine for a while than back to yoyoing on and off the net again dsisconnected while tyoing this reply.

I have spoken to Igni and Profpete will say what my connection is like tonight as he has been in the chatroom that I am moderating. When I am online.

I don't lie !!!!!

ProfPete · 22-02-2005, 23:32

Certainly has been timing out something croning tonight. Igni did mention something to do with fluctuating power levels.

If you think I did then sorry!

I was simply saying that you having problems tonite (and tonite is all you mention in your thread) does not mean the whole network is ******

hairy_mick · 23-02-2005, 06:22

that power level seams very high i take it they're positive and not negative kits

positive.

and before you ask no I am not calling India I did last time this happened and they just said the modem had died with no tests what so ever.

You're only seeing one end of the connection remember. I can see both. NTL techs can only see one end, too, unless they use my software

I've not got your current MAC, incidentally - the last modem I have for you hasn't been since since October!

*passes Kits an 8dB forward path attenuator.

Same suggestion as when you asked me about it a few weeks ago and for the same reasons, network adjustments, more likely actually network being fixed has pushed your power a bit high.

I'm wondering if you've had a power problem in the past on the low side and been moved to a lower attenuation tap to cure this, then the whole thing has been resolved by an amp replacement or tuning.

Anyway that aside the easiest way to resolve this is to just stick an attenuator on your modem. Interesting to note no DTV issues at all (assuming you have DTV?) I'd expect to see pixellation and other issues on the DTV well before power level on the cable modem causes disconnection.

Behave

And how does one person having a power issue make the whole network at fault - poor title which I may adjust.

Power fluctuation is bad, only problem is I don't see any fluctuation to speak of in the readings above, nor can I understand why drops of a 'few seconds' would be happening if it were that bad.

If the network were 'falling apart' I'd expect to see slow performance as well as drops, and those drops to last longer as modem loses synch outright rather than a brief connection stall.

Although no mention has been made of modem losing synch it's just been 'assumed' to be the case.

1.5 - 2dB difference between night and day is perfectly normal and miles within variation, the DOCIS specs allow for a much greater variation than this due to thermal effects on coax and amps.

DOCSIS specs allow for power level reaching modems to vary between + and - 15dB.

Disconnections aren't necessarily the fault of poor network maintenance. Someone stealing cable in your area and doing it badly will break your service quicker and more effectively.

Can anyone tell me why I cant access my NTL ftp? I need to upload some web pages asap. Worked fine yesterday but it isnt working now. My connection keeps getting timed out. I am using smart ftp. Is this something to do with the dodgy ntl network?

Any help greatfuly appreciated. Sorry if its a little off topic.

-EDIT-
I cant even access the NTL world homepage > 404 error
