Bittorrent & Disconnections - Ambit modems
 

Hi

this past week has been hell downloading with bit torrent, as soon as the connection hits max upload, the modem reboots :O I'm on the 2MB package and set my upload to 20KB/s (max is about 25KB/s) and has been working for over a year at these settings, this week I've been getting constant modem reboots, and to top it off my bro was downloading s World of Warcraft patch (in a different area of Nottingham) and he is now having the same trouble. any idea if this is a area fault due to the 10Mb Upgrades?

Modem:NTL 100
Downstream Receive Power Level : -9.93 dBmv Downstream SNR : 34.26 dB Upstream Transmit Power Level : 51.00 dBmv
any idea how i can get the modem logs? tried using docsis but looks like snmp is disabled :(

Thanks for any/all help

Is it ok with uploading turned off?

I'm having the exact same problem:

About 2 weeks ago I upgraded to the 10mb connection from a 2Mb connection.

The connection is fine when just simply web browsing when the load is light, however, as soon as some load is put on the connection (e.g. ftp'ing or bittorrenting etc), the cable modem reboots itself approximately every 5 minutes or so. This has only started happening since I upgraded to a 10Mb connection.

I have ran a speed test at adslguide.org.uk that says I am getting near enough 10Mb.

I have read about a lot of people who are having the same problem and most of them have the older Ambit modems (100, 120, 200). Of the people that have had their modems replaced for a 250 the problem has dissapeared. Now what bothers me is I know they are all capable of more than 10Mb, but is it that the older ones are more fussy of differing signal levels etc?

Modem: NTL Home 100 (Ambit) with ntlhm100_ntl0002.cpr config
Speed: 10Mb
Location: Leicester LE3

I'm going to call CS tonight to try and get it sorted, but any help or information would be greatly appreciated.

Cheers,

Chris.

with bit torrent turning down the uploading is not an option as is cripples the download. but its the same with any upload, FTP irc dcc msn file transfer.

I reckon the firmware was responsible for borking my 120 modem.
As I already posted Here the problem was only resolved by a new 250 modem.

edit: just a FYI, I'm still om the 3Mb so it had nothing to do with a speed upgrade.

I had the same problem when I had the 3com CMX cablemodem... BitTorrent would disconnect/reboot my modem sometimes knocking me offline for 5 minutes or more before the connection came back up. Since getting the 250 modem it's been fine, no disconnects at all.

put the up load to a minmium... lol

or stop downloading private stuff.. does help...

That's a prety strong allagation you're making there............ got any proof:rolleyes:

Re: Bittorrent, disconnections NTL:100 Ambit modem Nottingham
 

Set your max upload to 10k - you'll still get max download off Bit torrent. 20k is far too high, you'll just throttle your connection, and that maybe why your modem is borking? (probably not, but try it anyway)

called common sense..

Re: Bittorrent, disconnections NTL:100 Ambit modem Nottingham
 

exactly the same problem here, it also happens if im uploading anything else too, very strange, only happened since my modem firmware upgraded

Nottingham, DE7, NTL:Home 100 *On 3MB Connection though, not been upgraded to 10MB yet*

Re: Bittorrent, disconnections NTL:100 Ambit modem Nottingham
 

oh, the old common sense type of proof, that clears things up a bit. :rolleyes:

ok everyone, stop downloading private stuff. :D:D

IT WAS A LINUX ISO *cough*

On this forum they are suggesting it is the power supplies that are failing:

Strange that they are all failing at the same time?

Had engineer out for the second time this week. Same problem here altho the reset seems to be random. Doesn't matter if BT is running or not. Still on the 3mb line. Same as the original poster, my settings haven't changed and the connection has been stable for ever. When its working I get great speeds.

Engineer who came over today changed the modem and power supply to another 120 saying they are more stable than 250's. He also said that in the Watford area they had similar problems when the line was being upgraded to 3mb.

Could be these are problems as all the lines are being upgraded to 10mb. Nothing official on that tho obviously.
