ADSL modem recommendations

phill79

Hi

I have what the ISP's would call a long line (~7km). For a couple of months my Dynamode modem (with Conexant chip) has worked fine but recently it has been suffering from disconnections (possibly faulty).
I am currently borrowing a Netgear DG814 which is working fine but is no where near as configurable as the conexant was. Basically, I need a new modem.

Now obviously I can just buy another Dynamode but I was wondering what is the best modem to get especially for "long lines".
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

So anything that will improve this will be of use....if that is possible!

Thanks for any help given.

Try the billion range of modem/routers, or the zywal's. Not consumer orientated, so probably has lots of settings you can fiddle with.

As suggested, go with ADSL modem/router combination instead of a USB modem. Your SNR is quite LOW and the attenuation is quite HIGH .. I'll surely won't suggest you to go for any of the Netgear kits .. had DG834GT which always dropping when the SNR went as low as 6dB ..

Thanks for that, will have a look at them.

Should have mentioned that I was indeed looking for the combined 4 port switch ethernet one.

Pop over to forums.adslguide.org.uk and ask in one of the forums there - probably the best place to get techie info.

I would recommend you look at Westell routers or another router based on the TI AR7 chipset.

I am similarly "blessed" with a bad line (62dB attenuation, 4.0dB margin) and the Westell works better for me than several others I have tried (including a Conexant-based one).

Westell supply a lot of routers to DSL companies in the U.S. where telephone lines tend to be longer so they have spent time and money on R&D for longer lines and they have some proprietary technology specifically to address the problems.

The 4 port Westell costs £76 - not cheap but you do get what you pay for:

If this is beyond the budget, Solwise sell an AR7-based router for £37.95 which will still be an improvement on a Conexant-based model:

Thanks for that, will take a look. Looks like the thing I need though.
