>> Attenuation - 59 db

On *traditional* adsl you would have only just scraped 1Mb (limit is 60dB).

>> Noise margin - 9db

You have a bit of room for manoeuvre there (SNR margin often decreases as the evening goes on). so hopefully you should be stable.

>> d/stream = 1952 kbps

hmmm, that means your data rate will be set at around 1.5Mb which is a bit more than 1Mb, but not much.

You are soooo close to 2Mb, but not quite there, does the figure increase if you plug the netgear into the master socket?..
 
or even better the test socket behind the master socket?

Hi- just connected my new DG834G. Is it possible to find out if interleaving is on or off from the line stats? I can't seem to find it anywhere.

[roseway]

You have to go round the houses a bit to get the information, but it's not too difficult.

First logon to the router and then select this address:

http://192.168.0.1/setup.cgi?todo=debug

which should result in a screen which just says 'Debug enable'.
(That's assuming that you haven't changed the router's IP address from the default).

Then exit from the web interface and open a command-line window. Type:

telnet 192.168.0.1

You should get a BusyBox welcome message to confirm that your telnet connection is established.

Now type:

cat /proc/avalanche/avsar_modem_stats

This will give you a stream of information about the ADSL connection. Scroll up and find a section something like this:

        [Upstream (TX) Interleave path]
        CRC:    0       FEC:    0       NCD:    1
        LCD:    0       HEC:    0

        [Downstream (RX) Interleave path]
        CRC:    0       FEC:    0       NCD:    0
        LCD:    0       HEC:    0

        [Upstream (TX) Fast path]
        CRC:    1       FEC:    68      NCD:    0
        LCD:    0       HEC:    0

        [Downstream (RX) Fast path]
        CRC:    49      FEC:    0       NCD:    0
        LCD:    0       HEC:    0

In this example the interleave figures are all zero, apart from the first NCD value, which always seems to be 1, so this router is in fast mode. If you see zeros in the fast path sections and other figures in the interleave sections, then interleave is on.

Eric-thanks for prompt reply. I managed to follow your excellent instructions and concluded that I do have interleaving on. Next thing is to decide whether to keep it on or not.....!

[roseway]

You're welcome Delia. As far as I know, the only possible downside of interleaving is an increase in latency of 20-25ms, which may possibly be of some significance if you're an online gamer. On the other hand, it should give you greater stability. Your ISP should be able to get it switched off if that's what you want.

Some more questions- does anyone turn their DG834G off? If so do you just switch off at the mains? Is it OK to leave it on constantly?

[roseway]

Routers are designed to be left on all the time, and that's what most people do. The amount of electricity which they use is tiny, so it's really not an issue of cost or environmental friendliness. I leave mine on.

Eric

[kitz]

Ive had a router of some make or other continously connected for over 3 years now.
I never turn them off,
as roseway quite rightly said said the amount of electricty used by them really is doesnt amount to much.

[mr_chris]

My DG834G is left on all the time, 24/7. There are arguments that say it's actually better for them to be left on, especially since they get reasonably warm.

Heating up and cooling the components down every day will shorten the life of them more than leaving them warm all the time.

There are also risks associated with blowing components with a power surge when turning them back on. Some Netgear mains adapters are said to be unregulated, which means they don't give out very "clean" power. The voltage regulators inside the router therefore come under stress each time you switch on.

If you're worried it might be getting a tad too hot, you can always use the funky stand that came with it and stand it up on its end, to allow more air to get to its nether regions

[delia]

Thanks for all the replies. You've convinced me to leave mine switched on!

[mr_chris]

Heh, wasn't particularly out to convince you.. at the end of the day you should do what you're happiest doing, and not just because "some folks on the net said you should"

Having said that, I think you're doing the right thing leaving it on

[delia]

Sorry to keep asking questions, but for some reason, the "Wireless Settings" has disappeared from the side bar when I log in. Does anyone know why this is, please?

[delia]

Still interested in the reason for this, but I managed to get it back by powering the router off & on???

[kitz]

IIRC the Netgear web interface is within a frameset.
If you go in via the main page is the menu back on the left?

http://192.168.0.1

[delia]

I think our posts crossed, Kitz. I've got it back but am still baffled why it disappeared. The menu was there on the left as you say, but the heading "Wireless Settings" was not there- just "Basic Settings" and " "ADSL Settings". The re-boot seemed to do the trick. Any ideas?
