Hello!

I'm suffering from a flaky Xtra connection here in Glenfield. It drops the line every couple of minutes.

I looked at the ADSL stats from my DLink router (DSL-G604T). And it tells me things like:

SNR Margin: 2db (downstream), 27db (upstream)
Line Attenuation: 49db (downstream), 31db (upstream)

The SNR margin may change between 2 to 12 (and right now as I check, I get 2147483647 :-) Clearly a bug...)

Anyway, I read that low SNR margins are not a good sign (figures). Should I call Xtra customer service and complain? Can they do something about it? Is this clearly their issue, or possibly something with the wiring in my house?

I am wondering whether reducing the speed would help to improve the SNR margin. If that is so, how could I go about doing that? My router tells me that the data rate is about 3100 kbps down. Honestly, I'd be happy to trade some of that for better line stability. Looking at the router's menu, I can't find the option to reduce the speed, though. I don't even know if that could be done in a one-sided manner. I also looked at the available options in the Xtra broadband plan page, but I only find 'max' as the possible down speed. Also not very helpful...

Thank you very much...

The first thing I would do is call them and report that you've having disconnection issues... Once they are aware of the issue, tests can be performed and options put down on the table.

A SNR of below 6 is generally NOT a good thing, quite likely to lose signal sync.

You can try limiting your modulation, forcing it to g.lite (ITU G.992.2) which lowers connect to nearly 2mbps.

I too have one of these routers, and the first one had a fault, keep an eye on when you drop. See if the whole router has rebooted as mine was restarting itself all the time.

The only other thing telecom may do is change the pair you are on incase there is some chatter across it, or up the outgoing signal to you

Theres also a TONNE of suggestions in the OTHER thread you started about this.

Good point. I'm closing this thread and all replies are to be put in that thread.
