Default ADSL Router operating with 62dB loss good?



I'm looking for a router with a good ability to keep signals well.

Draytek UK support tell me that there have been users reportedly using a
2600 with up to 62Db loss on the line...

How does this compare with other routers, for example the Solwise SAR 715 or
the Origo ASR-8400?

Thanks in advance....

Could be true. The latest firmware is available in two versions, one for
"normal" connections, and one for "difficult" ones, so perhaps there are
some adjustments to the way it works with weak signals.

A 62dB loss means the signal voltage is reduced to 1/1259th of its
original value, so it's quite an impressive achievement.

I have the Alcatel frog so I don't think I can tell. Just I'm upgrading to a
1mb service and I'm aware I'm quite a distance from the exchange so I want
the best chance of getting a good working router with the signal on my line.

So is this perhaps better than other ADSL routers available?

I really have litle knowledge about this sort of stuff. All I know is I'm
quite a distance from the exchange and I want a stable reliable connection
:-)

Thanks for your help.

I'm not quoting the signal level on my line. I'm asking which router will
operate best with a lower than usual signal. This is because I'm only just
within the acceptable distance for 1/2mb services.

As I said, I'm not aware of any method of determining the signal level on my
line with an Alcatel frog and even if I could there's no signal currently on
my line as I cancelled the last provider and am waiting to be activated.

Historically Alcatel's are very good at holding a weak signal.

Only thing is very poor support and updates for the Thomson Speedtouch 510
(Thomson took over Alcatel) therefore considering a Draytek Vigor 2600.

The poster Roderick Stewart appears to believe a router that is capable of
operating with up to 62db loss is "an impressive achievement" therefore I
think that helped me make my choice.

I'm not sure how much use my experience can be to you because I've only just
been connected a few days ago, and my line has a loop loss of only 30dB, so
everything works just fine for me, and would probably work with a cheaper
modem. However, the availability of two versions of firmware for the Draytek
does seem to suggest that they've thought about this. The reason I went for
this particular unit is that it is one of the most configurable ones, and
incorporates a firewall. The setups can be accessed via a web browser, which
I don't think is usual, making them easy to mess about with. I've been
experimenting with the firewall filters and only beginning to realise what a
comprehensive piece of kit this is. If you just want something to set and
forget, then your needs will be different, but part of my reason for getting
into ADSL was to learn about it, so I've probably got something that if I
were honest is more complicated than I need, but it's interesting and fun.

Rod.

Do you have a url for the v4-->v4.2 information?

Yes, I have heard mention of this too. The roumer I have heard is that it
will be this year (can't remember where I heard it, probably on the
dslsupport forums). However, before that I heard August, and before that I
heard July so my patience is waring thin. Especially a I could probably
knock up a webmin plugin in a few weeks.
