Re: adsl 2 question


[re: MrSaffron] [link to this post]
 
hi, i have tried many speed tests all show the same kind of speed.

also tried downloading some files took a long time as well so i think this speed it says im getting is about right.

on the noise margin...................its now dark and the noise margin is already increasing

Current Noise Margin: 10.8 dB (Downstream) 5.0 dB (Upstream)

I have spoken to my isp many times on this, they say its down to me having a ally line

morning all.

still trying to find out why my noise margin drops during the day and rises at night time.

ive been reading on the net and ive seen it might be worth placing ferrites on the DC lead.
what are these and where can i buy them from.

thanks

Before spending money you need to see if switching off the kit makes any difference.

Also I would be buying http://www.adslnation.com/phpapps/catalog/product_in... first, as they gives better noise resistance, assuming all the phone wiring you have is twisted pair, and you have isolated the ring wire already.

NOTE: If the ADSL modem is sharing a power strip with other devices, simply moving the PSU brick to another socket on its own may help. As can moving devices that use switched mode PSU's (e.g. the new small mobile phone chargers)

hi thanks for the reply MrSaffron

Ive moved my dect phone to another power output, also moved the router away from anything electrical, so ill see how that goes.

I know my phone line is ally, would that be the cause of this problem.

On the cable itself, that you posted the link too, i brought one of these sometime ago, but the bt bloke removed it, and used the one which came with the bt2700, he said to keep using that cable, as the one i brought wasn't as good as the one that came with the one with the bt 2700, i have to say i didn't agree with him, but should i switch back to the one i used before bt came out.

If the supplied cable is of a flatish nature then its pairs are not twisted, certainly all the ones I've destroyed to look at are not using twisted pair.

Twisted pair results in a round profile for cables.

The ADSLNation cable often makes no difference, but as noise is random if you suffer it, then every little bit might help.

thanks, i think the one im using is slightly rounded, but i might as well buy one, in any case, if it might help its worth a go, for the sale of a few quid.

thanks
