Er.. it's fixed! For me, at least. Although I have no idea why. I don't know if NTL did something, or if slapping the modem and router about a bit did it. I doubt what I did below did something, but I thought I'd mention it anyway..

I unplugged the CM from the router and turned it (CM) off for a minute while I got the USB drivers ready for installation. I also turned the router off. I plugged the CM back into the PC again but via a USB cable this time. Installed the drivers, and restarted as the connection seemed dead. PC rebooted, but connection was still dead. I decided to leave IE to do its crappy Detecting Proxy thing which never seems to work and bugger off for about ten minutes.

I came back and finally I had internet access again. I jumped onto a Ventrillo voice chat server and stayed for a while. No disconnections! My IP address had changed, but not by much: very last digit went up by 2. Uh.

Then I ripped out the yucky USB connection, turned CM off, plugged the CM into the PC directly, turned CM on again, and made Windows hand out a dynamic IP (I normally use static IPs on the LAN). Connected again to Ventrilo and it didn't disconnect at all. Things are looking good.. except for the router. I need to buy a wireless router anyway, so it wasn't so bad after all.

I then added the router back into the setup and it's been working fine ever since!

It can't be a lose connection because either the connection would be On or it would be Off. Anyway, Windows didn't complain about an unplugged network cable. The router could've been b0rked somehow and the power down fixed it. Hell, even turning the CM off for a while may have sorted it out. I had a Motorola SurfBoard 4100 at my old place, and so don't really have any experience with the Ambit.

But one thing: how come other people are getting the same problem? I can only really put it down to NTL having done something about it.

Hey Nostra - thanks for your help on the phone! Did that other person that called you have the exact same problem as me? If so, then thanks to you and whoever else sorted the problem out.. for me, anyway.

Wow... glad I'm not the only one, actually.

I'm having exactly the symptoms JANoob described on page 3...

Quote:

1) slow / intermittent browsing
2) packet loss while gaming / high pings
3) slow internet generally, timeouts on websites, email accounts
4) sub-standard speed uploads and downloads.

In fact...they are so exact it's almost scary. Woo. Hm.

However, I am not in scunthorpe! *shock*

I'm in Oxford, and I've been having these problems for a few months now (I've been so damn busy, I havn't had chance to do anything about it).

I'm using an old Terayon TJ210, which my friend reckoned might be causing the problem (he was switched to an Ambit and stopped having similar problems, but I'm not sure whether it's the amazing fix he thinks it is)

Once again, the connection drops but all the normal lights stay on.

Here's some exciting DocsDiag information, just in case someone is interested...

it was EXACTLY the same issue as you even down to there being no packet loss to the Cable modem.

apologies for the small reply but on holiday from ntl for a couple of weeks and away from home having to make do with 9.6k internet via mobile

there was a raised fault reported on your ubr as a result and to be honest i left before a resolution was found... so im not sure if was has even been found... but it sounds like it has

So is it over subscribed or has the "free upgrade" lol been a total waste of time?
I,m really getting to the point of junking the lot.
What is really annoying is, i have given up gaming , ntl is useless for online gaming, but now browsing is almost totally useless, the e-mail is the joke of the inet.

Mauldor · 15-08-2004, 19:33

Well for me, it seems to have solved itself as others have posted here, MSn Stayed online, Gaming was fine last night, downloads making it all the way to the end and all web pages coming up straight away.

All I have done myself is change channel to 6 on SB4100 and forced a IP change by changing my MAC Slightly on my CM (only Way i know how to get a different IP)..

Not tested extensibly in any shape or form but seems ok at the moment..

Rone · 16-08-2004, 06:40

Well my problem is going to be "escalated" and someone is going to ring me today.
At least when it was tested last night, the guy was pretty dismayed at my connection.
So thats 2 of us now.

to Cable Forum, Eggo.

If your internet connection is fine while using a proxy, but dire otherwise, then I'd guess the problem is with the local transparent proxy NTL forces you to use. Renewing your IP lease would have no effect if this is the problem, I'm afraid, and nor would reinstalling your drivers etc. Manually specifying a proxy server is the only way to get past a b0rked transparent proxy, AFAIK. If you were finding your service was useless no matter what you did, there could be all manner of things wrong which people more technically minded than me would have to advise you about.

Have you contacted NTL at all?

Eggo60 · 16-08-2004, 11:54

thanks for the fast reply and for the welcome,

no i havnt contacted ntl yet, as i thought problem might had been something small that i had overlooked, but it sounds pretty bad so i will have to get me step dad to give them a ring once he arrives home.

Personally I wouldn't worry about it too much - call them of course, as it might just bring the problem to their attention more quickly than if you leave them to spot it themselves. But if you hang round here any length of time you'll learn that many of us make a hobby out of mucking about with our proxy settings. I normally find I can get pages more quickly if I choose my own proxy, instead of relying on my local transparent one.

Everything you need to know about proxy settings is to be found here:

Rone · 16-08-2004, 12:29

Well its now 1:30 pm and still no phone call from NTL.
I live in hope.

Rone · 16-08-2004, 14:21

Wooot just had a call from a nice chap from NTL, who lives in "our area" as it were, and he had a similar problem last night.
Looks like its been sorted, so lets hope it stays steady.
Its easy to complain, and it really annoys me when something IS done and nothings said.

SO THANKS TO ALL THOSE INVOLVED

TheAdmiral · 16-08-2004, 16:03

Glad to hear it!

Is Scunthorpe still being flakey? I know Oxford is.

Rone · 16-08-2004, 16:52

Spoke too soon, i,m doing a test d\load [the 3rd one] and i,m getting from 170 - 25 kbps on 1.5 meg.
Just like last night.
And if that stupid tart who says this "all at no extra cost" [cos its NOT] one more time...................
