SNR swings, disconnects and a long line

Hi

Aftermoving house and leaving my nice stable 8mb connection behind i have moved to a house much further away from the exchange and am having some strange issues, last night i was watching my SNR swing from 18, down to 0 up to 3 down to 0 etc etc

my line att figure is 63.4 although after reading else where on the forums its possible that this is simply not measuring past 63.4 !

i have a draytek vigour 2600v router, and last night i installed a firmware designed to handle longer distance lines but to no avail.

To make matters worse i saw a bt openworld engineer outside a few days ago, well before my current issues he was replacing some joins from the main cable to each house on our road ( all 7 of them

as we were chatting he told me another person had line "issues", He also mentioned thats its more than likley that the cable is aluminum which he described as stupid but its all they could buy at the time.

after talking to aol today it became apparent they wont talk to me unless i have a supported router, which i do not. however i do have several usb modems at home, the speedtouch ones i believe. can anyone tell me which are likeley to be supported by aol ?

in short, line length is at least 5km, snr varies from 18 down to 0 and the line att is 63.4

i get 512k

i have the bt master socket with the faceplace off and the router connected via a bt supplied filter, and ive tried other filters with no difference.

Is it possible to get bt to inspect my line and mabye run some copper, or fibre (ok ok fibre is dreaming i know

thanks and sorry for the longish post

I doubt if you could get BT to do anything. Their remit is to make sure the phone quality is acceptable.

Make sure your internal wiring is OK.

i am not using any internal wiring, as im connected directly into the back of the master socket face plate

I suppose I mentioned it because you said your router was connected by a filter. You don't need a filter for the router, only for phone equipment.

Except to get the modem cable connected to a BT socket

Not having one of the new fangled BT sockets I don't know if the test socket is for the modem or for the phone.

I know the filter should pass ADSL straight through but I suppose that part could still be faulty.

Without doing the maths, surely 512kb is not bad for that length of line and attenuation?

yes the 512k isnt too bad considering the line lenght,

however its not stable at all and im wondering if this is due to the line quality or my router or both and how i might resolve this issue.

Surely a line of that length would invite a lot more interference than a short one, especially from MW interference in the evenings.
Are evening the worse time for your speeds?

the condition appears to be worse in the evenings, compared to weekend daytime say, but im not there in the daytime to check.

i noticed last night was windy and that appeared to affect the dropout rate somewhat.

thanks for your responces
