Hi

At the moment I have my PC about 10-15 meters away from the phone jack.
Was running a phone ext lead, now I have moved Router by phone jack and running
Cat 5 to Sp2102 and computer. But line rate is still low at 2336 upload is 864.
Question is Why ? Router direct into phone jack.

SNR Margin DS 13.1
Attenuation DS 29.5
Atainable rate DS 2560 US 1032

Why not? Unless there was some local noise source that would affect a non twisted pair extension cord moving the router 10-15m closer to the jack would still leave 3000m or so to the DSLAM.

So bit confused. I was told not to run long phone ext lead to Router, But to put Router close to phone jack and run a long
Cat 5 from router to computer. So I need to keep all my leads as short as possible ?

No, it just means that your speeds are determined by your house/exchange locations. If you don't want to shift eventually the DSLAM may move closer to you.

Connecting the modem to the line using an extension cord can lead to problems. As nothing changed for you these problems weren't an issue.

When I had my computer next to the phone jack, my line rate DS was 5000+
I have moved the router back to the phone jack. So my router is closer to the dslam.
I am about 1.2km from the exchange.

Now you're modifying the story. Is this part of some continuing saga?

The line rate reported by the router won't be affected by the position of the PC.

OK so it must be some other problem then
Thanks for the help Bung.

Hello Warrick,

Just noticed the issues your having and did some looking into this for you. The sync rate from the exchange you are on is pretty poor and has some noise issues on the downstream. Not alot we can do in this regard so ive gone ahead and requested they switch you over to a ISAM port instead of the ATM you are on. This should hopefully make a decent difference for you providing telecom have a free ISAM port in your area. Once i have an update on when the change is going to happen ill give you a call to advise.

The funny thing is I was getting good speeds as in 6000+ . But ever since they have dug up our road to put in new water
pipes and I am sure telecom have been doing some digging at the top of our street...things have got worse.

The easiest way to get Telecom to check your line is if you hear noise on your analogue phone and complain about it.  They guarentee a good analogue service, but for ADSL it is simply "as fast as your line will go".  This is something I've read on an overseas forum where people had similar issues.

Your modem, line filters, or phone sockets (if they have lightning arrestors in them, which I think they do) could also be damaged which will result in poor connections.

IMHO you could probably attribute quite a few of the issues people have with ADSL speeds and dropouts to their house wiring. The fact that anybody who fancies themselves as a DIY handyman/handywoman can modify their phone wiring leads to houses with very dodgy wiring which can cause plenty of problems as you've discovered!

Sky installers and electricians aren't exempt either, plenty of them don't even seen to be aware of basic Telepermit regulations when it comes to running cable and mounting jackpoints.
