Hi,

I've recently changed from AOL (Fixed rate) to Entanet 8Mbps. I'm happy
with the speeds (quite often up to 800Kb/s) however, every morning
almost without exception my connection will re-establish.

The log is less than helpful

Feb 20 06:04:30 | local IP address 87.127.xxx.xxx
Feb 20 06:04:30 | PPPoA Connect with IP Address 87.127.xxx.xxx
Feb 20 06:04:30 | PPPoA Connection Successfully Established
Feb 20 06:04:30 | PPPoA Connect with Gateway IP Address: 84.45.xxx.xxx
Feb 20 06:04:30 | remote IP address 84.45.xxx.xxx
Feb 20 06:04:30 | primary DNS address 195.74.xxx.xxx
Feb 20 06:04:30 | secondary DNS address 195.74.xxx.xxx

My current stats are:

Connection Status Connected
Ds Rate (Kbps) 8128
Us Rate (Kbps) 448
DS Margin 12
US Margin 26
DS Line Attenuation 26
US Line Attenuation 14

LOS Errors 0
Peak Cell Rate 1056 cells per sec
CRC Rx Fast 0
CRC Tx Fast 0
CRC Rx Interleaved 3
CRC Tx Interleaved 0
Path Mode Interleaved
Uptime 14hr 33min 21sec



Any pointers much appreciated.

What does the log say *before* the re-establishment of a connection ?

once per day!

I've been keeping a detailed log of all my (PlusNet) connection drops for
the past fortnight. During that time, the connection has dropped on 43
occasions. It has automatically re-established itself on all but 4 of those
occasions. On each of the 4 occasions when it didn't re-start, I had to
re-boot my router to get it going again.

Before I went onto MaxDSL (several months ago - so it shouldn't still be
re-training!) the connection would stay up for weeks on end.

Absolutely nothing. All that is in the log is details of the previous

Sounds like a marginal SNR, maybe if you fell to the next lower sync
rate it'd be OK. Have you tried another router?

BT line check gives expected speed 8Mbps on my line, which is what I
get. I cannot work out what would be causing noise on the line at 5am
which isn't there any other time. Is anyone able to tell me if my
figures are comfortably within the margin, or borderline?

(7.5 at the moment). As far as I can tell, as often as not the line doesn't
lose synch - it's just that the LCP session drops and then re-establishes
(and no, I don't have inactivity timeouts). If the line *does* re-synch, its
always within a fairly small sped range - in the 3600 to 3800 kbps region.

I *have* got another router, although I haven't used it recently. That used
to consistenly synch at a lower speed than the one I'm using now - but the
connection was no more reliable.

A SNR in excess of 6dB should be fine. Some routers (Netgear?) Have a
habit of negotiating too high a speed and therefore causing SNR to drop
to well below 6dB.

Certainly there is a difference between 14 times a fortnight, all at the
small hours when I'm asleep - and 43 in the same time frame. Must be
annoying for sure.

BT runs regular tests on phone lines which tend to be
about the same time every night and which could be
disturbing your connection.

Loz wrote:

Strange. Mine will show the disconnection and give some clues as to the reason.

See what happens when you disconnect the phone line. Does that get logged ?

It's not that for sure.

I echo that.

Pre-maxing, my connection using an X-Modem modem was rock solid.
After Maxing it used to drop at least once every day.
Adslnation confirmed that product was Max-compatible.

Then I changed to a Draytek 2600 and it's been rock solid ever since.

Thanks. Oddly this morning it never dropped - and I'd even turned
debugging on the connection to see if I could get any more information.

Yes, it says "DSL carrier down"

I'm beginning to suspect a fault with the router. Is it possible it could lose
power for some reason ?

No, the router hasn't lost power - since if it does, the system uptime
resets - which it hasn't been doing.

I seem to recall reading that Plusnet use Tiscali wholesale to supply
some of their customers, maybe they drop idle sessions?

After the ISP we used switched from BT to Tiscali Wholesale's
Datastream based service, the connection would drop when it had
been idle for some time. Our particular model of router
(an old Safecom) didn't like it much. Although it would reconnect ok,
it would become unstable so I set up an account with www.l8nc.com
and kept the connection alive by pinging it once per minute. You
might not want to do that with a capped account though.

dynamic IP addresses) have an enforced idle timeout - but mine doesn't.

Mine *can* stay up all night - when all the computers are switched off, and
just the router running. Equally, it can drop when a computer is active. For
instance, I might read a message in this or some other NG, and then click on
next message only to find that the connection has dropped. Whenever my
computer is on, the connection is never idle for long even if I'm not there
because MailWasher is checking for mail every 10 minutes. [My bandwidth *is*
capped - but I never use anywhere near the bundled 2GB per month, so that is
not an issue].
