About a mouth ago I moved my pc and had to use a phone extension cable and it hasn't been liking the cable because its been disconnecting loads of times and the speed has dropped from 7mb to 25-30k.

About 4 days ago I had my phone socket moved by my pc, but the speed hasn't increased at all, but the connection speed has. Im getting a bit concerned because I would have thought the speed would have increase a bit by now, but its still at a rubbish 25-30kb/s?

is my line ok from this info guys?

The connection speed is more or less consistent with your attenuation and margin but as for throughput you might have been put on a lower profile by your ISP due to the issues you experienced while running of the extension.

If you are with BT there's a website you can use to check your profile but I forget what it is.
 
ds and us attenuation are way out, should normally be something like 2:1. More atten on the upstream compared to downstream is very very wrong.

:confused: Que?


For an attenuation of ~50dB that sync looks ok. If this was a recent change however the line profile will take time to update. If you were getting 30kbit before it won't jump straight back how it was. The line will 'Train' itself up to the defined maximum profile for that sync rate. But in some cases, especially where the line has been particularly unstable this process can take up to 14 days before the 'Training' process reaches maximum.
 
That's not the most reliable speed test but certaily 110ms latency to a UK server and more upload than download doesn't look right.

Ping google.co.uk for 10 repeats then try a bog standard HTTP/FTP download of a driver or something a few MB in size and see what you get real world. Speedtest.net isn't the most accurate for stuff like that, it can get screwed over by firewalls and other shizzle.
 

His upstream attenuation is 48, his downstream is 41db. Normally the US atten is half of the downstream seeing as the US frequencies are far lower than DS. If the router are reporting these figures correctly then something is very wrong, either a faulty modem or wiring etc. I understand that his sync is in line with the DS attenuation but that doesn't mean his connection is problem-free.

Yeah was thinking it could be the wiring in the box, cos a m8 of mine moved the socket and just rewired the wires back into the same slots, so a wire might not be making good contacted I guess.. ummmmm

I might asked him to check it, or get someone a qualified to come out to it:confused:

Line length has more of an effect on attenuation than anything else. The longer the line the closer the upstream and downstream tend to get. It's not uncommon to see short lines with 18-20 downstream and 3-4 upstream, which is a ratio of 1:6.
The symptopms demonstrated in this caseseem more likely beyond the DSLAM interface. Notably the high latency and drastic differential between sync and throughput rates.
 
See if you can get hold of a different router from a friend etc.

you need to find out if the figures reported by your router are correct, if they are correct then you have a wiring problem.

Yeah I live in the countryside and the bt line checker a few months ago said i'll get a max of about 5mb, but I actually get about 6 -7mb

But Ive just checked it now and it says 3mb???

Congratulations, BT report your local exchange is ADSL enabled, and your line (000000000) could have ADSL speeds of up to 3.0Mb broadband.
 
In that case, I'd A. get your connection sorted, incase there is something not right your end, and look at LLU providers that offer ADSL2+. As for the same line length ADSL2+ will give better performance.
Have a look on samknows for providers of ADSL2+.

I think I give it a few more days to see if the speed increases at all, before I check stuff.

Whats the point of adsl2+ if my line is only capable of 6 -7mb speeds?

Because the speed you'll get on ADSL2+ will be significantly faster than you'll get on plain ADSL.
The capability you're talking about was based on your line's capacity on ADSL. My line did about 4.5-5Mbit on ADSL, it now does about 12Mbit on ADSL2+. It's a different technology

Ahh thanks, Will deff look into that once Ive got my line sorted again,, will I need a adsl2+ router?
