Modem for "long lines" reqd

Hi everyone,

I have a "long line" ~7km so am only able to get 512k from ISPs but
recently my modem went on the blink and started to have frequent
disconnections. Tried what the ISP said (unplugging all phones etc) but
that never worked, so borrowed another modem (Netgear DG814) and it now
works OK.
My question is, what is the best, or good modem for a long line to avoid
disconnections? Will this also do anything to solve the problem with SNR
and Attenuation "noise", here are my stats:
d/s SNR: 5.5dB (varies between 4 and 5.7), u/s SNR: 14.0dB
d/s Attenuation: 63.9dB, u/s Attenuation: 31.5dB

Thanks

Sorry I can't help with the question - but I too hav a netgear and
wondered how you got yhis information out of it as my NG (GD632)
does't seem to provide it. My BT ones does... but it ocked up so I'm
back to the NG!

TIA

Hi, I got the info from my Dynamode which is currently on the blink. The
netgear doesn't give any stats though, even when the firmware was
updated, which is a bit cheap of them really.
Sorry.

There isn't a lot you can do at your end to improve on your figures,
especially if you are using the master socket & have either filtered
off all your extensions, or have no extensions, or disconnected them,
as they are the product of your copper (hopefully) pair between the
socket & the exchange. Your attenuation isn't bad for a 7km line &
the SNR is just bareable (it will really depend on how bad you want
ADSL).

As for the best modem, well you've found that Netgear appear to work,
so that's one answer. My suggestion, I'm afraid, isn't so cheap &
that's to get a Vigor Draytek router as I've known them to give
stirling service in some problem situations. The price of the 2600's
should be dropping now that they have rolled out the 2800's but it all
depends on how much you want to pay..

Draytek provide special firmware for 'long' lines, but I don't know how
successful it is.
You can pick up the 2600 range on Ebay at reasonable prices,
they are dead reliable, so no worries there,
that's how I got mine.

Thomson Speedtouch routers have a very good rep for long line DSL
connections. Both models below are able to use Max 8Mb products.

ST546 - wired ADSL/ADSL2+ router
ST585 - wireless ADSL/ADSL2+ router

For the record I also have a very, very long line >9Km. I am using a
Netgear DG834v2 on Zen Home 250 which is on MaxDSL. This router
synched successfully when the BT engineer's test modem would not. I
get a maximum noise margin of 6 bit the connection seems stable. As a
matter of interest the attenuation is reported as 63dB but I know in
reality it is way over 70. I have since learned that most routers can
only report a figure up to 63. Anything greater is ignored so bear
this in mind. 12 days and still connected!
