>> If the Gateway has changed then its only possible if  1 there is a loss of Synch . 2  if PPP is lost .

Correct

Re PPP connection dropping..  as roseway mentioned the most common is load balancing.. but there are some more ways this can occur.

I have maintained the Zen Fault tracking sheet . ** I will Email a few  of these to ZEN.
One of the ZEN guys was telling me that during his training he was told that Loss of authentication could not happen on its own ??.
Regards Jeff

I dont supopse you know who it was that you spoke to, I can confirm 100% that is not the case (as you guys know) and it most certainly is not something that is in training, perhaps its something that has been miss-understood but ether way if you know it it is I can go "Educate" them for you.

Right now looking at our server logs, i can see the line dropped @14:28 for 20secs. about 28mins before the drop the line experienced packetloss:

http://smokeping.eper.net/cgi-bin/smokeping.cgi?displaymode=n;start=2009-08-14%2004:28;end=now;target=Residential.ADSL.zen182598

This is in turn caused the loss of the PPP session. Armed with this information we'll send this back to BT and see what we can find out.

Hi
@ Leo
I have just replied to the ZEN update . Lost PPP again today after just over 24Hrs .

Sat, 2009-08-15 15:16:06 - LCP down.
Sat, 2009-08-15 15:16:13 - Initialize LCP.
Sat, 2009-08-15 15:16:13 - LCP is allowed to come up.
Sat, 2009-08-15 15:16:30 - CHAP authentication success
If I am reading the smokeping graph correctly It corresponds to some  packet loss at about that time
Regards Jeff

@ Leo,

I wonder if the following crumb of evidence might be of help?

I was attempting to do a BT Speedtest at Olga's @ about 07:55 and got TWO successive tests errors "Unexpected result received when querying the network to find your services connection details. Please try again shortly ......."  before the third one was successful with a meteoric throughput of 196 kbps. I have the Zen username permanently in the remote laptop's clipboard and always paste it into the second BT webpage, so it definitely isn't finger trouble - although it might just be data corruption en route to the BT Database ? (Olga's connection is remaining remarkably steady at present.)

Kind regards,
Walter

I noted the same thing yesturday. BT did see an issue and passed it back to Diagnostics who then could not see it. I'll be passing it back and asking them to investigate the packetloss, alos noting that other lines with other ISP's are seeing the same fault.

NB: Just to add before anyone gets confused, the packetloss happens before the line drops and not just at the time it drops.

Kindest Regards,

Leo

sorry bit OT..  but lol @ the clue bat

For what it's worth, I changed my router's protocol settings to PPPoE and LLC/SNAP two days ago (as Kitz mentioned earlier in this thread) and the difference is amazing! Absolutely rock solid PPP (as opposed to frequent dropouts before). So I would definitely recommend trying the "wrong" settings if you are having problems with this.

@Kitz...   did you get any meaningful data from your request on the Plusnet Community site for exchange info on this problem?

Hi
lost WAN for 4 secs . I think it was to do with the target snr . It has now dropped . My synch speed increased by about 300Kbps. The short down time would perhaps explain how sometimes when the target has been reset there has been no apparent disconnection.


Sun, 2009-08-16 15:58:36 - Initialize LCP.
Sun, 2009-08-16 15:58:37 - LCP is allowed to come up.
Sun, 2009-08-16 15:58:40 - CHAP authentication success

hi
On sunday lost PPP again

Sun, 2009-08-16 17:05:20 - LCP down.
Sun, 2009-08-16 17:05:28 - Initialize LCP.
Sun, 2009-08-16 17:05:28 - LCP is allowed to come up.
Sun, 2009-08-16 17:05:31 - CHAP authentication success

Then OK for 46 hrs . I did a reboot as requested By Zen . As BT had been doing more investigation

I wonder if this problem has anything to do with Netgear routers in particular.

Hi

It does not seem like it .There are others with the problem. Its getting to be more of a problem . Other ISPs are also seeing it .

There is a netgear problem with routing and BE . John from routerstats knows about that one

Hi

Well had almost 4 days without PPP loss (one reboot as requested in middle of that). Unfortunately after About 11PM last night it all went pear shaped again with loads of attempts to Authenticate  throughout  the night some improvement early morning . Now been up 8hrs . Lan and Wan over 3 days with a SYNCH of 7264 Kbps.(best its ever been) .ZEN are investigating  

 thank goodness not with T------  any more

this fault seems like its a widespread problem.
Regards Jeff

BTW have accepted the case as being somewhere on their network.

I have not heard anything yet, But i think they need time to uinvestigate as this could be related to the Broadcom chipset issues faced by 21CN customers.

Hi

@Azzaka  Did you see this link
http://community.plus.net/forum/index.php/topic,78341.0.html

It refers to Belkin and BT Voyager 2110 having similar problems .
