Re: Bittorrent & Disconnections - Ambit modems
 

Just giving my new 250 a heavy load, and no reboots so far... :D

Re: Bittorrent & Disconnections - Ambit modems
 

i've had a bad day, i've been waiting since 12pm today and the engineer who was supposed to come to my house to sort my 120 modem out hasn't turned up
I am very annoyed and just want this sorted, i fear i'll have to be on the phone to CS tomorrow to explain why he didn't turn up
I am still waiting as the callout is between 12 and 6 but i don't live in hope

Re: Bittorrent & Disconnections - Ambit modems
 

Ring them up now mate... and tell them you dont want to have to call retentions for loss of earnings... ring 0800 0522000 (option 5) and confirm they know of your booking.

[edit] - i couldnt help notice your a Cov lad yaself... the guy that saw me might be on his way to yours now ?...

Good to hear Jamb... ;)

Re: Bittorrent & Disconnections - Ambit modems
 

Slyder i tried but couldn't get through. As i type i'm still waiting for this bloody engineer to turn up
I am very angry and if NTL can't sort this out within a few days i'm thinking of changing to BT
I've had disconnections since Last Saturday FFS

Re: Bittorrent & Disconnections - Ambit modems
 

I do know the CV2 area are having problems at the moment, according some recordings while on hold to cs earlier. (Im also CV2 so I know there are engineers in the area today) Bloody disgraceful mate tbh, I dont know what to advise accept ring them again and keep it ringing. Someone will pick up.

Re: Bittorrent & Disconnections - Ambit modems
 

ok then, i wonder if this fault is releated to me having the disconnections on Saturday,if it is NTL are bloody slow at fixing stuff

---------- Post added at 17:21 ---------- Previous post was at 17:20 ----------

can anyone confirm from NTL about the CV2 area problem and a fix time if necessary?

Re: Bittorrent & Disconnections - Ambit modems
 

I tested again today and I am still seeing the problem. What do I need to do to escalate this ?
I'm on 10MB, in Reading, and the modem dies after a few minutes of downloading.

Re: Bittorrent & Disconnections - Ambit modems
 

Cough... turn modem off...cough...phone ntl...cough...say modem is an ambit and it was having trouble downloading and now is dead... cough...Man comes out with brand new modem...cough...get something for this damn cough ;)

Re: Bittorrent & Disconnections - Ambit modems
 

If your lucky. My engineer insisted on testing the modem. :mad: This is how I done it thou. Engineer showed up

"Oh Ive done what the guy at CS told me to do"
"Which was ?"
"Box it all up as they said a new modem exchange was agreed"
"ok he shouldnt of said that, im gonna have to unpack it all and test it im afraid" :mad:

After repeating 100 times the older Ambits were (and still are) having trouble the with the 10meg - he finally agreed to changed it.

You could say it likes to die and stay dead for a certain amount of time plus rebooting does not fix it. Thats a good one. :cool:

Re: Bittorrent & Disconnections - Ambit modems
 

A few days ago i was having problems with Morpheus and my Ambit 120 modem disconnecting.

This morning, and RIGHT NOW all im doing is browsing this website www.cableforum.co.uk and im getting disconnected every 30 seconds.

I'm on the 1MB service, if i call CS will they replace my 120 for a 250 even if im not on the 10MB service, because this really isn't fair when trying to do something here that i get disconnected!

- Cheers

Re: Bittorrent & Disconnections - Ambit modems
 

If you word it correctly they may do. As I said earlier, if you disconnect it then ring them up telling them it likes to die whenever it feels like it, they cant run any tests on it meaning they have to send an engineer out. He will probably test the modem but all you say is the problem is not with the line but the modem itself and reproducing the problem is hard as it is random.

Re: Bittorrent & Disconnections - Ambit modems
 

could i get this thread sticky? thanks.

Re: Bittorrent & Disconnections - Ambit modems
 

Thank God for this thread...I've been having these problems since about November 17th and have been completely stumped as to what was wrong. Since it only ever seemed to happen when using Azureus, I thought that was the problem. Like others, I was getting reboots every few minutes, so I tweaked some Azureus settings (max connections, limited upload rate) which has definitely helped - now I get maybe half a dozen reboots a day, which I can live with for now.

I never twigged that it could be a problem with the modem itself. :doh:

Re: Bittorrent & Disconnections - Ambit modems
 

I thought I'd provide some final info because this hasn't gone anywhere from my point of view.
People internally had seen the thread and escalated it to me because I am working in several areas at the moment.

The end result of asking here and elsewhere for information was:

13 responses
8 had nothing to do with firmware upgrades.
I asked for MAC addresses for the remaining 5
I got 1.

As you were one of the 8 I'd have to say "probably".

Without more data there isn't anything anyone can do.

Re: Bittorrent & Disconnections - Ambit modems
 

Over the last 2 weeks, I have had many issues with line speed and dropped connections when using BT.

In the last week, my modem has rebooted 15 times, and is now up to 817.
The opening comment from the CSR I spoke to this morning, was 'Do you have an old or new modem, sir ?'

The plan is to replace the modem tomorrow morning, and I'll test the connection as soon as this happens. I was planning to work from home tomorrow anyway, and NTL's proposed visit fits in perfectly with my plans.

I'll post feedback when this service visit is completed and my testing is complete.

I can normally tell within 20 minutes as this is the mean time between BT failing.

Mark

Re: Bittorrent & Disconnections - Ambit modems
 

Just to update followers of the thread. Had my 100 MODEM swapped out last week for a new 250. The 100 MODEM rebooted constantly when used "under load".

The replacement has not rebooted once. Good luck everyone.

Re: Bittorrent & Disconnections - Ambit modems
 

After talking to some colleagues at work, I'd like to have one last go at getting some information on this.


If your recent experiences meet the following criteria

ntl: 100 or 120 modem (only these models at the moment)
+
3Mbps or 10Mbps Tier of service
+
Heavily loaded upstreams eg significant ftp:, P2P or BitTorrent.
+
frequent disconnections

Please provide the following information to Russ who is providing it on to me.

Thanks
Peter
ntl: Internet Product Team
-----------------
Location?

What apps are in use at the time of failure - specifically Bit Torrent as per the thread, or also P2P/ftp?

Also is it only under heavy upstream?

How frequent are the disconnections?

What are the LEDS doing at the time of failure? Specifically I am interested in the Sync and Rdy Leds †“ the two on the right hand side


Power levels

Downstream, Signal to Noise, Upstream

You can check these through the modem diagnostic pages. See the Article How do I check my power levels + what should they be? at this link

MAC Address of the modem.

Re: Bittorrent & Disconnections - Ambit modems
 

OK, my Modem has been replaced with a 250, and now my router is n't working, but that's my problem, as the modem works fine connected to the PC.

The BT disconnections continue, even after the 250 installation. I'm not even able to get into the modem configuration page, i.e 192.168.100.1

My upstream frequency is quite low according to the engineer who visited, although the modem read out's for some of the readings were not the same when he checked them with his handheld diagnostic unit.

For my problem, I don't think it's NTL related anymore, rather than Windows / Networking / BT Client issues

The reason why i believe this :

My Mac can stay connected to the BT client for 3+days
Modem lights look normal
Windows needs to be rebooted in order to get Web / BT access working again.

I'll just have to switch to using ht mac for any BT files I need.

Re: Bittorrent & Disconnections - Ambit modems
 

Mark / ukcobra

Did you provide details to Russ to pass on to me? I'm wondering "which one" you were.

Peter

Re: Bittorrent & Disconnections - Ambit modems
 

Err, originally yes, but not the recent call.

I can still reproduce the problem, but I'm fairly sure it's a client/windows issue, as my MAC Mini does not have the problem.

Mark

P.S If you want my new Mac Address and details I can post them , however, when I see the problem I cannot go into the modem config to pull any technical details from the config.

Re: Bittorrent & Disconnections - Ambit modems
 

Hey guys - my modem tends to die when im using BitLord or Azures also. Never at maximum upload either. I have the Ambit 100 modem

Re: Bittorrent & Disconnections - Ambit modems
 

i too also have the same problem with my ntl connection which has been upgraded to 10mb modem keeps rebooting itself every other minute and have called ntl cs they said everything was fine over at ther end when my modem wasnt rebooting i have rebooted my pc to correct this and when i read the forums in here i now understand what the problem is and will be ringing ntl tomorrow

Re: Bittorrent & Disconnections - Ambit modems
 

Davemck,

What model of cable modem do you have, it should say on the sticker underneath.

Re: Bittorrent & Disconnections - Ambit modems
 

the modem is an home 100

Re: Bittorrent & Disconnections - Ambit modems
 

I thought it would probably be a 100 or 120 as these seem to be the ones prone to the rebooting problem.

Re: Bittorrent & Disconnections - Ambit modems
 

My disconnections occur with my 120 and my 250 modem.

Re: Bittorrent & Disconnections - Ambit modems
 

Hey guys - after switching my car insurance to Ethernet... I mean modem... the issues stopped happening, maybe this will be of some help to some of you guys! ;)

Re: Bittorrent & Disconnections - Ambit modems
 

Mine has always been on Ethernet. I suspect there are many problems here, we appear to have similar symptoms, but the root causes are clearly all different.
I've giben up with BT on the PC, as my MAC can do it without the modem crapping out.

Re: Bittorrent & Disconnections - Ambit modems
 

Hi, I've been in contact with a chap that works for NTL. I provided him with my MAC address and cable modem stats and he said the following:


ADMIN EDIT (Russ) - Please do not publish the contents of Private Messages without the sender's permission.

I have sent an apology to the person concerned, it was stupid of me to post comments from my PM with him and I'll make sure in the future I always get permission first.

Sorry!

Re: Bittorrent & Disconnections - Ambit modems
 

Same problem here :( its really annoyin ****ing me off! To get this new modem wat do i have to do? and does it cost? Atm i have the First version of the Cable Modem, little grey box lol!

Re: Bittorrent & Disconnections - Ambit modems
 

I've had the exact same problems during the last week and a bit. Last night I tried leaving my modem completely disconnected, and this morning everything seems to be working OK like it should be. No idea if it'll last, but you lot might want to try this if you're desperate enough like me.

Re: Bittorrent & Disconnections - Ambit modems
 

My connection's been fine all day since I left my modem entirely disconnected over night. I've been able to reliably browse etc whilst uploading and downloading via FTP, Bit Torrent and WASTE.

Re: Bittorrent & Disconnections - Ambit modems
 

My silver 100 replaced with new blue 250 today - cured my reboot/disconnect/hangup/lockup problems. Today's engineer said that the 100's are just not up to the 10mbit service - might support the speed, but they are not happy with ntl's current firmware image.

Re: Bittorrent & Disconnections - Ambit modems
 

Another case of how a new Ammy 250 corrects problems shown by an Ammy 100.

Re: Bittorrent & Disconnections - Ambit modems
 

It's nothing to do with the modems not supporting 10MB.

The connection problems are also happening to me and others on 1MB & 2MB that have older modems.

Re: Bittorrent & Disconnections - Ambit modems
 

I've got a 250 modem. About 3 months ago I had a 1Mb line installed and in the last 2-3 weeks I've been trying to use bit torrent downloads to download the (legal) archives of a radio show I like, but my modem keeps rebooting. I've now upgraded to 10Mb and I get exactly the same problem. Everything is fine in speed tests and when just surfing the web but as soon as I try to use bit torrent, the modem reboots after about 5 mins. Really annoying. Will phone NTL tomorrow but not sure what they will bea ble to do as it seems like they don't know what is going on.

I'm happy for those people who have changed to the 250 modem have got rid of the problem, but I've had a 250 modem since the start and it's no good for me.

If they don't get it fixed I'll just change to a different company, I don't care if it costs a bit more, as long as the torrents work.

Re: Bittorrent & Disconnections - Ambit modems
 

I have the same symptoms - connection repeatedly dropping under heavy download (downloading simultaneously from news groups and BitTorrents).

I live in Leicester (LE3) and have a silver ntl:home 100 modem. I recently upgraded from 3mb to 10mb and the problem has been occuring since then. I get around 1100k/s flat out.

I've sent a PM to Russ D answering his questions.

Cheers,
BD

PS. This is my first post :)

Re: Bittorrent & Disconnections - Ambit modems
 

I still have the problem, with just 1 torrent and a 250 modem. I was on 3MB and now on 10MB.

My MAC works fine, so I think this is more of a client issue than a BB supplier issue. If it was an NTL fault how does it explain I can use the Mac version of Azureus fine ?

Re: Bittorrent & Disconnections - Ambit modems
 

hi brickdog welcome to the forums, russ will make every effort to help you I am sure of it, the cableforum team have helped solve numerous issues for people who visit this site.

Re: Bittorrent & Disconnections - Ambit modems
 

Same here Guys, I've always had a Blue 250 modem, I moved up to 10mb and now the router keeps hanging.
Here is a message I posted elsewhere:

Has anyone seen/heard of this before, it is driving me mad?

I have NTL 10Mb via an NTL 250 modem.

If I plug my either of my wireless routers (Netgear WGT624 & Buffalo tech WZR-G108) into the cable modem they will hang every 10 minutes or so and I then have to repower the router.

If I plug my PC straight into the Cable modem it works fine and dandy, not one crash or hang of the PC.

I'm wondering if it is the router(s) or is the cable modem sending iffy signals or something.
Note. the logs on the routers state no errors recieved.

Please help someone

thanks

Re: Bittorrent & Disconnections - Ambit modems
 

NTL 120, 10 meg leicester LE3

Constant reboots when connection under load. "Obtained" a 250 but NTL would not add it to the network. The annoying thing is they happily swapped my SB 3100 the week before for the 120 by me just calling up following advice the 3100 wasnt up to the job. What a mistake that was as the 3100 seems a much more solid modem.

Engineer booked for tommorow who i will lock in the house until he replaces the ****e modem with a 250.

Re: Bittorrent & Disconnections - Ambit modems
 

NTL 120 here, fine on everything, newsgroups, ftp, torrents, full speed up and down with no problems


merry xmas

Re: Bittorrent & Disconnections - Ambit modems
 

Have the prolems been resolved with regard to BT clients or have we all just given up ?

Re: Bittorrent & Disconnections - Ambit modems
 

I'm still getting problems - I've not been in touch with NTL yet though. I'll do that when I'll be around for an engineer if I need one as it seems quite likely that a change of cable modem will be the first suggestion.

Re: Bittorrent & Disconnections - Ambit modems
 

All seems fine here with new 250 modem

Re: Bittorrent & Disconnections - Ambit modems
 

I upgraded on xmas day from 2mb to 10mb. Speed wasn't great until I changed to an ethernet cable (on the advice of one of the CF Team) and then it shot right up. Max before was about 4-5 meg, after 7-8 meg.

I also lose connectivity with heavy BT use, torrents with many seeds/peers. Was mainly when using Azureus. Changed to Utorrent which seems to have helped so far.

Ambit 120, Glasgow.

On another note, can anyone tell me why AFTER uninstalling Zonealarm firewall I seem to be getting full use of my 10mb service. Here are my results before and after uninstalling Zonealarm...

This is my speeds with ZA running...

Fri, 6 Jan 2006 20:37:57 UTC

1st 512K took 563 ms = 909.4 KB/sec, approx 7493 Kbps, 7.32 Mbps
2nd 512K took 546 ms = 937.7 KB/sec, approx 7727 Kbps, 7.55 Mbps
3rd 512K took 563 ms = 909.4 KB/sec, approx 7493 Kbps, 7.32 Mbps
4th 512K took 578 ms = 885.8 KB/sec, approx 7299 Kbps, 7.13 Mbps

Overall Average Speed = approx 7503 Kbps, 7.33 Mbps

and with ZA completely uninstalled...

1st 512K took 438 ms = 1169 KB/sec, approx 9633 Kbps, 9.41 Mbps
2nd 512K took 422 ms = 1213.3 KB/sec, approx 9998 Kbps, 9.76 Mbps
3rd 512K took 437 ms = 1171.6 KB/sec, approx 9654 Kbps, 9.43 Mbps
4th 512K took 438 ms = 1169 KB/sec, approx 9633 Kbps, 9.41 Mbps

Overall Average Speed = approx 9730 Kbps, 9.5 Mbps

Is this normal or will another firewall help?

I will get back to you if I have anymore disconnections with BT.

Re: Bittorrent & Disconnections - Ambit modems
 

Im On 2mb 120 modem , this week i have only started getting problems Bitorrent or direct downloads was very slow and have not notice any reboots atm.

Re: Bittorrent & Disconnections - Ambit modems
 

Na... lost connection a few times last night while using 4 big torrents. Gonna try CS

Re: Bittorrent & Disconnections - Ambit modems
 

*bump*

Any one still got the same problems? I Still get them (When using Azureus mainly) And the upload stream reports @ Approx 50~5kB/s (Via a connection monitor) (Azureus is capped @ 40K Inside the settings)

Ambit 100, 10Mb
Software Upgrade File Name : ntlhm100_ntl0002.cpr
Activity on lights: (Sync/Ready stay on, D/S Constantly flashes, Eth Flashes, U/S Stays off) Then about 5 or so seconds later, The modem will "Restart/Reset".

Back when I was on 3Mb, it was fine, Then after the firmware update (I was still on 3Mb back then) But I started to get disconnected... Then I got upgraded to 10Mb, And still getting the disconnections.

Re: Bittorrent & Disconnections - Ambit modems
 

I found out that when my laptop is connected to the modem diretly via ethernet, I get no disconnections, but if I am using my wireless router, I get disconnections. So if I want to use torrents I plug it in directly.

Seems in my case that my problem is with my wireless router and not with NTL. I think it can only handle a certain number of simultaneous connections. After a random amount of time, my router reboots itself, and I dont get any connectivity again until I pull the plug on both my modem and router and switch them on again.

Is anyone having the disconnection problems without using a router?

Also, I didn't know that you get much less bandwidth over a wireless internet so it was good for me to plug it in with a cable anyway.

Good luck,

Stoo

Re: Bittorrent & Disconnections - Ambit modems
 

Yep, I'm still getting the disconnections and I don't have a router. My modem is connected directly to the PC via ethernet.

I've also noticed over the last couple of weeks that my speeds have dropped drastically. About a week after signing up for 10Mb I could get 9Mbps, now I only manage around 4Mbps.

Re: Bittorrent & Disconnections - Ambit modems
 

I've noticed it only tends to happen when i'm uploading (I've had about 10 restarts of the modem today - if not more) and it's kinda annoying.

Re: Bittorrent & Disconnections - Ambit modems
 

Ah I have this problem with my 'ntl home 100' modem. Does a 250 modem fix this issue then? It's very annoying. I've got an engineer coming tomorrow so i'm gonna have to convince him that it's broke.

Re: Bittorrent & Disconnections - Ambit modems
 

The restarts seem to be more aof a modem specific problem, as in not ALL the one type of modem resets. But if yours does contact NTL reporting the problem, if they dont fix it (they sometimes say its a blah blah problem, should be fixed in a hour turn off ya modem) phone up again and blame the modem saying you want the new 250, worked for me, no resets at all :D

Re: Bittorrent & Disconnections - Ambit modems
 

Well it seems like I'm an unlucky one. I just hope I can convince Mr Engineer that I need a new modem

Re: Bittorrent & Disconnections - Ambit modems
 

I had a 120 and after reading various threads i locked the engineer in my house until he gave me a 250.

I have not had a single reset since..........

You do the maths :)

Re: Bittorrent & Disconnections - Ambit modems
 

It did not solve the problem for me.

Re: Bittorrent & Disconnections - Ambit modems
 

kg501 - firewalls require processing time, so yes it will slow down. You might get latency problems too = longer ping time. A fast computer will help. So not all problems are caused by Ntl!

2nd - cheap SOHO routers have limited NAT entries. BT consumes lots of entries, a poorly programmed BT client may not close clompleted entries and so use up the allocation. CM and Routers will auto close unused entries after a time out, this might be too long a wait before the table is exhausted. The software then has a tendancy to reboot in order to clear out. Not necessarily a bug but a design feature in case entry clearing isn't happening properly - remember these devices were never designed to support more than a few computers, under normal use 10 pcs might open 200 - 1000 ports tops.... P2P can open 1000+ on 1 machine. FYI my cheap router has 4096 entries in its NAT.

---------- Post added at 10:56 ---------- Previous post was at 10:52 ----------

For someone with this reboot problem: If u use newsgroup downloader like GrabIt, then use only this and download at maximum some binaries and see if a reboot occurs.... This will help analysis of the problem. - I currently dont have reboots, on 2Mb and only use newsgroups.

---------- Post added at 11:00 ---------- Previous post was at 10:56 ----------

The new 250 modem could simply have more memory, thus a bigger NAT capacity. Perhaps by listing bad BT clients? it might be possible for someone to find a good client

I can crash/reboot (all the lights turn off, and come back in 30 seconds) the connection in other ways too, just by doing too many things at once - but still using my connection in a normal way that many people do.

Re: Bittorrent & Disconnections - Ambit modems
 

too many things? so maxin your connection with 1 http download wont crash it.... but 2 will?

this doesnt make much sence.

Re: Bittorrent & Disconnections - Ambit modems
 

I agree.

It mainly happens when doing anything else when some p2p program is running.

---------- Post added at 14:18 ---------- Previous post was at 13:30 ----------

I've just had an engineer at my house. He found the my signal level was too low, and this was definitely the cause of the problem. He fixed the signal level and rushed off.

Needless to say, it died again when testing it under 'load'.

Re: Bittorrent & Disconnections - Ambit modems
 

i have this problem

when using bittorrent i get a local networked unplugged and my speed drops but im using a 265 from virgin media...i phoned CS and they said sounds like the wire is broke

but i changed my settings in my BT client(utorrent) to 20 max connections and 20 global connections and it has stopped with my upload speed at 2---still get max DL speed at 2 for my UL
