Thanks for coming back baby_frogmella.
Well previously I had a 2 megabyte connection (admittedly slow by current standards) on BT Wholesale for something like ten years and that never disconnected ever as far as I can remember. As soon a I switch to a TT line I get trouble so I don't think it's my end.
I'll try the router(s) in the socket but I'd be very surprised if I had a wiring problem, I'm sure it would have shown itself before.
6db?...that sounds like permanent disconnection land lol...but I'll bear it in mind.
Any idea how long it takes for your account to be recognized by TT Forums?
Basic explanation here.
SNR is noise margin. This measures how strong the internet signal is (layman terms).
A high noise margin = strong internet connection. A line will drop when the noise margin goes low, so if the noise margin drops to say 1db the broadband may drop. This is because the internet signal is too weak at 1db (again layman terms)
A high noise margin = strong internet connection & can deal with lots of interference.
HOWEVER the faster the internet connection goes, the LOWER the noise margin goes. (basic explanation - & works in this context)
On your old 2Mbps connection the noise margin would have been ALOT higher than it is with TT... A higher noise margin means the line could deal with LOTS more noise before disconnecting...
To get you quicker speeds on TT that noise margin has to be reduced.
MOST lines are stable with a 6db noise margin. This gives around 5db of noise before there's any massive problems
However on poor setups the noise can be erratic and can jump 10 / 20 db randomly.
Currently your noise margin is 12db, this is not great but is TTs default I think. HOWEVER something might be pumping out interference down your line. This may create noise...
On your old 2Mbps connection your noise margin may have been 20db. When this appliance pumped it's say 15db of interference down the line, the noise margin went to 5db but the connection held on.
On the new TT connection, with a lower Noise margin of 12db. When this interferes, 12db - 15db = -3db. This is not possible. The line drops out. Disconnection.
This is why the problem can very easily be at your end. You are comparing a 2Mbps connection to a new quicker connection which isn't a great comparison.
So best bet is to get in that TEST socket. If it goes away you know something in your house is blasting out interference which is causing the drop outs.
