Noise Margin 2db?

[#1]

My Noise Margin stats on my router is constantly jumping from 2db-8db.. Is this right? My connection seems really bad tonight.. Can't load speedtest. Tried cmd tracerts/ping -ts and they are 'Timed out' or 'General Failure'
help!

[#2]

Do you have a netgear router - say a DG834 model? If so, it is very unreliable reporting SNR so I would not always believe what it says.
Have you tried rebooting the router which can resolve any router problems and possibly get you on a different gateway which may give you better speeds.

Sorry missed out my 'Line attenuation' is at 8db and hasn't moved.

I'd also suggest rebooting your router, it's been online for almost a day so I'm guessing you've not tried this yet? Have you recently asked for interleaving to be turned off too?

[#5]

I've read not to reset my router?
Yeah had interleaving turned off yesterday.. and on a Netgear DG834G

A quick reboot isn't going to do any harm especially with your line being as short as it is. If you don't want to do this though then there should be an option within the router configuration console that allows you to disconnect/reconnect the PPP session.

is this true of all versions of the DG834? i have a DG834G version 2 and have noticed a similar thing. SNR can vary by as much as 4db around the current average reading. this means if my target SNR is 6db and i do a resync during the day, i often see spikes down to 1db or even lower at night. usually the router holds the connection though. i think my current target SNR is 9db, and the lowest SNR reading i have seen at night is 2db, which doesnt seem to cause a problem. overall the SNR reading jumps up and down constantly around the average figure.

Is there any other way to check my SNR?
I did a reboot around 1:30am like you said and its working fine again now, thanks.
One thing I want to know is, my Router normally all the time Syncs at 8128 kbps downstream and 832 kbps upstream, yet my Profile to PS is 6.5mbit?

Peter, it's well known that Netgears give stupid figures when the margin drops to (or below) zero, but other than that I've not seen anything at suggests that the SNR they report is inaccurate. Could you elaborate please.

Noise margin is the difference between the level of the ADSL signal and the background noise on the line. Because the environment is full of electromagnetic signals this will vary constantly and is perfectly normal.
I am very fortunate to have an excellent connection - my profile has never, ever been anything other than 7150. My routerstats graph from today is attached. As you can see it varies significantly.

Have to get your self a decent line then John

In the new year I'm getting myself a new faceplate, some cable and a couple of RJ11s

[#13]

Good idea Strat

Or I could borrow Chris' blue ballpoint pen and straight edge

I'd just move Dick if I were you, looks like a hopeless case there
