That is high. :(

Lines stable and it drops to 6db at peak train times so in theory i could go down to 12.

but mine is set by the singtel firmware

You're doing better than me, Alan, I'm synced at 3488 on a 57db line.

Indeed - it sounds like a pretty good line, all things considered. I used to get that sync on my 47dB line! :o

That was this morning, I've had another Sunday burst of noise and I'm now down by 1000k, with a 15db NM on the upstream. Weird.  :shake:

Was that with carriage? It seems slightly high...

£16.50 plus £4.50 carriage for a brand new modem isn't outrageous.

Here is all you need to know to get it working http://www.idnetters.co.uk/forums/index.php?topic=8927.0

Thanks for that Glenn.  I'll let you know how I get on.

It's not too bad, Tac, and good value even at that price, but they did go through a phase of being much cheaper. Maybe supplies are drying up?

I've actually got a couple I wouldn't mind getting rid of, Tac. Drop me a PM if you're interested. :)

Already done the deal thanks Seb  :)

I know I'm prolonging this thread but I thought it might be worth posting some other stats as of 18.55pm:

noise margin upstream: 20 db
output power downstream: 15 db
attenuation upstream: 31 db
tone   0- 31: 00 00 00 04 45 56 66 76 67 77 77 66 66 66 55 00

All tones above this are zero.

All tones above this are zero.

I don't know if this gives the more technically minded a clue as to what's going on.  Other than the obvious that the line's c..p.  :)

Could be, as the Business Hubs seem to be quite hard to find.  Quite a few of the other sort (single SSID) but they seem to go for £20+, which does seem excessive compared to what I paid.

I buy 2700HGVs regularly from Ebay and only ever pay around £10 inc P&P eg this month I bought a BNIB 2700HGV

What is the date of the referendum for England to become an independent country ?

I think it probably depends who's around at the time you bid.  When I looked, there were several going for much the same price as I paid, but I'm not a regular on ebay.

However, I'm satisfied as I don't regard £21 for a brand new modem as expensive.  If it doesn't produce better results on my line I can always sell it for no great loss.

If it sorts the  problem then it is a cheap fix  ;D

Good luck
