High Attenuation, noise on phone line

Your Dad is very, very, lucky to get that speed in rural Spain, and I bet he pays more than we do in the UK, especially as Telefonica have an effective monopoly.

In Spain, the faster the speed, the less you pay, now how daft is that? .. only about 10% of Spain can get the highest speeds.

He only had it put in recently, they came out and laid a cable especially and knowing my dad (penny pincher!) he didn't pay much for it and I bet he is not paying any more than the £25 a month that I am paying for this, he said he was on their 'light' package and he could have the speed doubled if he wanted!!!

I'll email him tonight and find out exactly what he paid for it, installation and monthly cost.

He also only pays 6 euro a month for a mobile phone on contract with comparable service to my £35 O2 contract so I wouldn't believe everything about comms being expensive in Spain.

Fair enough, but the max speed available via Telefonica is 4MB, and that is 40 Euro's a month A IVA ( VAT ) after the first 3 months.

I guess he must have cable BB provided by a local private business, when I say rural I mean 10 miles from the coast and 20 miles from Alicante.

I just plugged my router direct inside the master socket, the attenuation was the same and when I plugged a phone into the filter the noise was there so its either my line externaly or my router thats faulty, I'm going to buy a router and see if its the same, if it is I'll just take it back.

Thanks to everyone for your input.

Keep us posted. Most routers come with a filter or two, so it would be worth swapping those in if the problem persists.

i noticed during this discussion, that star or daisy chain house wiring was mentioned, does this make a difference, is one better than the other

mine is a sort of combination of the two options (like two Y's joined at the bottom )
something like this >----<----to street.
with four wall sockets, one at the top leg of each Y, one of which is connected to my modem ,with nation filters at each outlet

is this good ,bad ,or indifferent

thx in advance

Probably bad, by modern standards. Star topology was common pre-ADSL, but that really is a bad idea for noise - daisy-chaining will generally give a better result.

Just noticed my post was resurrected!

Since then I've tried a linksys which was ok but wireless and VPN was rubbish, I got another DG834GT and the problem was the same (thanks to PC world for the rentals!), I had BT in via IDNET who replaced the master socket which seemed to do the trick but after a week I noticed the problem creeping back.

Maybe the line is fit for purpose in BT's eyes but both netgear routers I tried didn't like it? Maybe they operate in some weird way that conflicts with my line conditions??

I've all but given up but as they're so cheap I'm off to look at the 2wires I keep hearing so much about!

To judge by my experience of the 2700, and I'm still a newbie with it, you won't be disappointed. I have had both better sync speed and a more stable noise margin since installing it.

Call BT 150 and tell them you can intermittantly hear other people's conversations when you're on the phone.

It is an almost impossible problem to track down and they'll probably just swap you to another pair no questions asked. It costs to much to get the RFI team involved to investigate fully.

That may make the problem worse.... but it could also increase your speeds substantially.

I like your style, Ducky!

I was a consultant for BT for a year. I know a few tricks... That one I actually learnt by accident quite recently. I never knew standard proceedure for fixing strong intermittant cross-talk was to swap the pair!

With my luck, I'd get the worse pair they had.

I am actually lucky, I was an early adopter, and when I had a problem, the BT engineer was very friendly, and swapped pairs to get me the best result he could. As I manage a 2500 profile while my neighbours are on 1000 or 500, he seems to have done a pretty good job.
