View Full Version : Paaaainfullll Boadband speed.
Hi - My first post, so here goes! ;)
2MB BB, 3 TV STBs.
Have recently had 3rd STB installed, which has been faulty (choppy picture), so had NTL come out to replace it today. Thats all fine now. Yesterday, internet started going at about 10KbitSec, fluctuating between that and full speed (would stick at 10 KBPS for about half an hour, then go to full speed for 10 mins roughly). Asked NTL engineer blokey about it today, and he said it would etiher work, or not. And it might as well not be. All in all, he couldnt be bothered to look at it for me.
Any ideas what it could be? All connections ok, tried through router on several PCs, and direct PC <-ethernet->modem.

Does your internet come through one of the STBs or through a Stand-Alone Cable Modem (SACM)?

Thanks!
I've been trying to get to the web interface on the NTL branded Standalone modem, yet with no luck. When connected straight in with the ethernet cable, and ip set to 192.168.100.2 on the PC. Cant even ping 192.168.100.1
any ideas?

Check Connection settings in IE and make sure you arent using a proxy this will stop you accessing the CM configuration.
Which firewall software do you use also if any?

You will have problems connecting to the CM if you are specifying an IP on the PC when it is connected directly to it.
Make sure you haven't got your firewall set to stop you accessing the CM.
Set your connection to get an IP address automatically.
Reboot the CM and then the PC.
Now try again.
Your PC should pick up the IP address assigned to it by the CM.
Right. Connected, straight ethernet cable. No firewall or other internet impairing stuff. Is the address i need the one that appears as "Default Gateway" in the windows Lan status thingy?
Right.
I worked out the whole web interface thing :p:

roughly how far are you from the cab/dp, the small green box somewhere on the street that connects you to NTL's network?
are you having any problems with any of the STB's? ie, loss if pictures intermitent freezing of channels that kind of thing?
Had a problem with 1 STB - replaced STB and fine now.
If the thingy your talking about is the greenish box on the side of the house, its just the other side of the wall. If not, what am i looking for?

is should be a small metal cabinet in the street somewhere, it might be by the side of your house, although it is normally at the end of the road or near a junction on the road.
Theres a thing under the ground about 25m away (with CATV printed on top). Does that make any difference?

That's the one, sounds like you're good and close.
What other issues could there be? I believe that i have accertained that it is not the PC Side of things (have tried router + several Pcs, or pc straight into SACM). Anything else?
OK, this isnt funny now! 0.6KBytes/Sec DL rate. Whats the best way to deal with this RE: NTL? What (if any) speed tests do they trust?
Thanks for the help.

best thing to do is what i am going to do turn off ntl go with a better one some other ISP one that know what they are doing
bulldog or uk online are ok which i will be going with one of them very very very soon my ntl speed are crap 56k is faster then my 3mb wate of time ringing them i did and got told loads of bull:mad: :mad:

bet to leave ntl go else were i am i get slow speed i should be on 3mb getting speeds like err 56k they routers need balacning
Why have they upped all the speeds when they obv. cant handle it? A 5 yr old could explain the concept of the traffic jam to you, so what gives?

What could be the scenarios that are causing problems? Most customers will be doing nothing different to what they were doing before the speed increases and by that I don't mean trying to max out their connection 24/7. If you have a faster connection and want to download say a 10Mb file you will only be in a position to cause problems for half the time. I know that you could get a file of that size with a dialup speed but you would then be using bandwidth for a very much longer period of time with more chance of contention coming into affect. Faster speeds only reduce your capabilities to below what they were before their introduction if some users try to max them out for extensive periods of time.

No capacity issues would cause that sort of performance, you've a fault somewhere.
Presume that you've done the usual BS to check for virusez trojanz spywarez and all that claptrap?
Have you tested for packet loss at all?
With your permission I'll ask one of the lovely moderators to give me the IP address you are posting from.
Thanks.

*Removes the gun from Chris T's temple.
I am in the Bishops Stortford,Harlow area. I note that the service status page on NTL 's home page has shown a "degraded service" since Dec 22nd 04!!!
Works fine a.m. slows down around 4 p.m. stops dead after 7 p.m.
I am on cable moden Img and it seems (to me anyway) that there is a contention ratio problem. From December last year though,how long does it take to restore a useable service? Another week of no evening service and I fear its ADSL for me.

Nope!
Would tell you if I knew when it's going to be sorted.

Yes, if you could pass on the IP that would be great.

I am having speed issues as well - cable modem - checked for virus and spyware - no issues there -
My speed has been real slow the past few days - did a check on a few sped sites. I am currently on the 2MB speed - just did another check and this is the result

Let's hope you receive less abuse, and get fewer people taking liberties, this time.
I, for one, think it's great that you're prepared to help people here in your spare time.
I'll PM you my long list of problems now :)

See how it is now, http://www.adslguide.org.uk/tools/speedtest.asp
Direction

True Speed (estimated)
Downstream 1895 Kbps (236.9 KB/sec) 2046 Kbps (inc. overheads) Upstream 178 Kbps (22.3 KB/sec) 192 Kbps (inc. overheads)
Looks pretty good. What did you do? Thanks anyway!

Not really! Modem is fine as far as I can tell, all connectivity between us and your modem looks really good, pings are fine, etc.
Might be a problem with the connection between modem and wireless, I presume it's bad even connecting wired to modem?
I will try that later. Is there any prog that i can leave running testing every X secs / Mins?
Ignition
24-04-2005, 20:16
Weird, your modem seems stuck at ~200kbps max download, even though as you posted above it's able to do a full 2Mbps.
Not sure of a program to constantly test speeds, pings are doable with something like pingplotter though, if pings are becoming an issue when it all goes wacky.
I can confirm that your wireless isn't being hijacked at any point though, just to eliminate that from the equation.
Dont think any wireless hijacking. Nothing abnormal on server DHCP Logs.

Nah as I said no evidence that hijacking was in progress, think I said could confirm that it wasn't happening.
Presumably it's still misbehaving :(
Try connecting a machine directly to the modem (firewalled obviously) to eliminate your LAN entirely. Thanks! :)

Forget that, done some more searching and found the issue.
If you have an attenuator on the back of your modem remove it, small device sits in between coax cable and modem.
If you don't you'll require an engineer to attend, you've low downstream power.
Hope this helps.
