Unfortunately, it's not showing us line attenuation or noise margin. :(

Ideally, we also want to see what your error count is like.

I'll reconnet my netgear tonight.

Rik

You'll need to keep it connected for 24 hours or so, Dev, to build a picture of the error count. To access this:

Enter this in the browser address bar:

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

Thanks RiK I will try later tonight or tommorow because of teh 24hour bit.

The line stats we can start looking at sooner, of course, but we really want to get an idea of the error count to understand what is happening on the line.

The line stats from my netgear below the noise margin goes to 0db sometimes. Comments please, but note router only online 12mins. I like the idea of max attainable rate, but not getting near yet.

It is the low noise margin most likely causing the reconnects. One thing you can try which may have an instant effect is removing the ring wire from all telephone sockets. It's on terminal three, and usually orange/white.

One thing we can say immediately is that your line does not appear to be interleaved.

The SNRM is low, and probably the cause of the disconnects, though I note that you don't use the Netgear everyday, and I've found Netgear's to be inaccurate.

Have you considered a new router? I bet that would cure this. Something like a 2Wire 2700HG or a SpeedTouch 585v6 would be great.

Sorry Seb but I use a Draytek Vigor 100 ADSL2 with Dlink DIR655  normally. i discon three times in game tonight took a log after playing these are the stats I appreciate if you take a look. I'll reconnect it now.

Allready done that Lance thanks.  :(

Are these stats from the Draytek, then? How long's it been connected for? At the moment, it looks fine; a SNRM of 6dB and very low errors, but if it's only be connected 5 minutes, that's misleading.

I can't help but think that this is another case of the AR7 chipset issue.

Rik

For that attenuation, you're probably connecting about as fast as you can, I suspect your line is not in prime condition, Dev. The thing that continues to worry me is the relatively low upstream noise margin. That is unusual.

I did find that Draytek's were not particularly good on Max myself, so moved to the Netgear and now the 2700. The latter may well offer you significant improvements.

Sebby

You're right, Rik. I managed to miss that.  :-[

I've seen it a few times, but never has there been a definite explanation, other than noise on the upstream frequencies, for whatever reason. Often it disappears by itself.

Rik

Though it might indicate a noise susceptibility which is causing the re-syncs.

No these were taken after 5 hours with discons but monitored by telnet from the Netgear. Sorry I took a while to get back had a firewall issue couldnt access my router page after switch. I'm back on Dlink Vigor rig now.

just ran the bttest again profiles gone down a bit  :(

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 4500 kbps
    DSL connection rate: 832 kbps(UP-STREAM)  5696 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 4236 kbps

If you wish to discuss these results please contact your ISP.

If you are experiencing problems with specific applications, servers or websites please contact your ISP for assistance.

Your test has completed please close this window to exit the performance tester.

I think someone was surfing last time thats why the lower transfer. Will I get my profile backup again? I noticed that my pings had gone up reconnected again this router and they are back as per first switch over post.

Rik

Hi Dev

You're just synched at the bottom speed for a 5000 profile, so I'm guessing you've had a low sync when changing kit around. The profile will recover in 3-5 days, provided you don't have another low-sync event.

Thanks Rik, its been up 8hours since so far and pings have recovered they went up also before.

Rik

Good. Try and keep things stable for a few days, Dev, and it should all settle down for you.

Have a karma for passing 30k  ;D

Rik

Thanks, Dev. It's a sign of how the forum is growing that the first 10K took 10 months, and the next 20K took less than six!

Still, I can only think it's the router, as - other than the upstream SNRM - everything looks fine.

Rik

It's certainly a candidate, Sebby, I think Dev needs to be patient with the connection for a few days and let it settle.

Agreed. It's a shame that both routers have the AR7 chipset, but like you said, let's see what happens over the next few days. :)

11.5 hours up  :). I have the qnap disconnected I wonder if that could be cause of my problems.

Does my dlink have same chipset then Seb? AR7 I have heard of probs with them I know, a lot of people go the speedtouch route.

Rik

I'm slightly puzzled, Dev. I saw the Vigor and said "Draytek" in my mind. AFAIK, Vigor is a Draytek brand name, not D-Link.
