Barrie, ON | Looks like a great modem. Is it? I'm using the 2Wire 2700HG-B and it's ok, but wonder if there's an advantage to switching. Looks like you can do more with this modem. |

In my experience, a good 2Wire modem beats every other modem out there. Some let you tweak but I find the 2Wire modems because of the chips they use tend to give you the best performance out of the box so no adjustments are required. |

Customability is a nice asset but yes, at 63 dB attn. the 2Wire is a champion. |

Thanks.
Because of my ATT, I'm looking to optimize my crappy connection. It appears I've got the best router for the situation.
Thanks all.

Anyway, here's the tweaked configuration which i'm
testing right now. Factory defaults can't compete
with it, FirmWares are too dumb to search for such
a set of minute trade-offs, i suppose. As you can
see, i didn't sacrifice any bandwidth this time...
Resolution per bin being 4 bits less i'm expecting
to have a sturdier signal, only a noise curve will
tell me if it's less susceptible to the cross-talk
noise which seems to have increased significantly,
lately. I'll need to optimize my RCO, eventually.
I'm hoping for some quieter noise curve than this:

Moving Bell's main line away from power lines just
didn't seem to do much and i think i've found why:
The white part is PVC, no magnet will stick to it.
Plan-B was to shield Bell's main line, i've got no
noise curves for that just yet but something tells
me this isn't the end of my misery... Stay tuned! |

2wire suck's I have 2 brand new and refurb and speedstream 6520 and 4200 both the simens outpreforme the 2 wier modem |
|
| Hi Piotr_1,
Some people are very happy with their SS4200 while
others prefer a 2Wire, for me it's a GNet and i've
shown why i appreciate it exactly but you and i we
don't seem to speak the same language if all there
is to discuss is related to devices that "suck"...
I'm curious about all brands and models as long as
i can obtain more than qualitative information so,
if you don't mind, you'd please me quite genuinely
if you could find the time to add such a snapshot:
SNR Drops at regular intervals, HiVolt, 2007-Oct-18
The same goes of MLerner even if he was here about
two month ago already. I don't mind, i'm patient!
As you can see, this thread is related to tweaking
a variety of parameters and, while i test them, it
provides a great opportunity for trouble-shooting.
All i care about is what an SS4200 or else will do
for me should i get my hands on one of those and i
woulnd't mind at all if you could show us what the
SpeedStreams 4200 & 6520 are capable of, honestly!
