they want to drop my line speed!

hi people. I need a little help. I've been having some trouble with my 8meg dsl line from bulldog broadband. Basically, the downloads can be a bit sluggish, with p2p never really going past 300k, and averaging on around a hundred. When it was first installed, I could get speeds of around 700-800k quite a lot so I raised this with bulldog. The only solution they could give was to sync my line at 4 meg (i was having none of it!). Everything else they suggested failed. My line stats:

Upstream Rate (Kbps) 576
Downstream Rate (Kbps) 7392
US Margin 21
DS Margin 7
Modulation MMODE
LOS Errors 0
DS Line Attenuation 43
US Line Attenuation 46

Can anyone suggest another way to sort this, because i know the line can perform well.

Thanks

 

It could be as simple as there are more people using the system that your being fed out of and there is not enough bandwidth to give you the speeds that you are used to having! A speedtest will tell you your peak speeds at that moment of the test and not really give you a good idea of your speeds during a long duration of time, like during p2p sharing!
Also check you pings with a tracert to see if there are any problems with the flow of data before it leaves your providers network!
Hope this helps!

If you're 100% sure it's your line, there's usually not a lot you can do in these situations. BT will change things with how your phone is routed, or the DSLAMs, etc. *If I remember correctly, Bulldog uses a BT line*. Have you had BT test your line to see if it's still capable of using the full 8MB? There's a good chance that it's not. If the carrier of the line isn't BT, get whoever the carrier is to check it. So before you continue to complain to your ISP, check things like this out. The longer the phone route to the CO, the lower the speed your phone line will be capable of getting through broadband. Also keep in mind that rain effects the quality of the phone lines, thus lowering the quality of the broadband connection.

Also, check with Bulldog to see what the best MRU/MTU settings to use would be, and configure these in your modem, or maybe even your router. It may also be your modem that's making everything sluggish. Bring it to a friends place who has DSL broadband and see if preforms well. If you have a router in place, connect directly to the PC with the modem and see if you experience the same issue. Make sure that the phone line between the jack and the modem is as short as possible.
Have you ever considered that it may be your PC? Check for spyware, etc. Not to mention, you can only download as fast as the other person can upload.

 

Oh, you SO sound like a former ISP help desk technician.

And, IIRC, the UK does not have Bell Telephone service, if that's what you mean by BT. I'm sure petemate will correct me if I'm wrong.

 

BT = British Telecom.

 

Thanks everyone. I appreciate the help. netstat shows no spyware connecting to the net. The engineer on the phone commented on my low ds margin which should be 10-12 decibels, but i get about 7-10. I asked if he could manually raise this, but he said it wasn't recommended. I currently use an optimizer to set mtu/mru levels, but i do have a recommended value i can try. what is everyone's view on the ds margin/attenuation issue?
