Constant disconnections, help please!!

welshbhoy · 01-09-2007, 00:26

Hi, I currently have an NTL 250 modem with a 20mb connection. I am running Win XP service pack 2.

My connection runs ok for a short while and then without warning pages cannot be displayed, mostly whilst downloading in the background. I have to turn the power off to the modem and then restart my PC, turning power back on to the modem to re-establish a connection. This happens more when I am downloading via torrents. I used to d/l up to 5 torrents at one time and everything would run ok. I now only d/l one torrent at a time and always limit the d/l speed to 250kbps, but it still disconnects.

I have contacted VM and the tech guy told me he can see I have had 26 disconnections in the past 2 months and that this is normal

. NORMAL!!! what am I paying for?

It is really getting to me now, some days I have to reset up to 6 times. Tech support cannot explain or at least don't seem bothered being as it's normal behaviour.

Does anyone have any experience of a similar problem and maybe a remedy for it?

It might be because your UBR is over subscribed but post your modems snr, upstream and downstream power levels in case you have a signal problem.

Thanks for the reply Mick

I think I may have fixed it. I had a look at my device manager and there was a yellow exclamation mark next to my ethernet card so I downloaded the drivers and reinstalled them. I left the pc on with the torrent running at about 4am this morning and it's still connected.

I'm hoping that's it sorted

keeping my fingers crossed.

How do I get to check my modems SNR ?? and the upstream and downstream levels anyway? I wouldn't' mind a look for curiosity's sake.

I'm sure that's going to make a lot of sense to someone, but me WHOOSHHHHHHHHH

An interpretation of that info would be nice

You open your browser (IE, Firefox, whatever) and in the space at the top where you type the URL of wherever your browsing to (e.g. http//www.thinkbroadband.com) you type "http://192.168.100.1/" and hit your return key. It'll come back and ask you for a username and password - both, as I understand it, are "root" (without the ").

Try limiting your upload. Maxing your upload bandwidth will kill anything else you try to do, the upstream requests cannot get through.
