[DSL] Random PPPoE disconnects

Over the past month or so I've noticed that I seem to get random loss of PPPoE session. It comes back right away, but it seems like i get booted often. This is a small sample as the router only logs for one week. I should set up a syslog for it. There is no modem sync loss during this.

I wonder if this could be somehow related to the new Cellpipe modem firmware? I don't recall this happening before, certainly not this often.

Has anyone noticed a similar pattern of PPPoE session disconnection, but no modem sync loss? I have a ping alert monitor from an outside connection, so I know exactly when it happens.

Hard to say if I'm getting them to a large degree, but I do seem to have some in the logs:

Seems awfully coincidental that the first two examples are almost identical on time.

I've been wondering about this, but didn't know what to ask.
Note the connect times. Huh?

I have also experienced two unusual PPPoE disconnects recently where the modem sync was not lost. My modem is an ST516 on a 6/0.8 connection. Firmware has remained constant.

I've noticed them more in the 2-5am range... I set up a syslog now, so I'll be able to keep track of them for longer period of time.

Keep in mind Bell maintenance window is 2-7 I believe. So if disconnections occur in that time frame, it could be related to that.

Now if you get disconnected outside those time frames, something else may be up. Although the disconnections don't seem to be last extend periods of time, but would anyone be able to report that this is also happening when connected with the U:test@test / P:test login?

I just got my VDSL a few days ago and noticed this happening to me too. My line was solid on ADSL profile (both profiles from the same stinger).

I'm rock solid on two lines (both 25/7). I think I've had maybe one disconnect in 5 months and it was around 2 AM so likely Bell doing some work. Now I'm not using the Cellpipes so I can't say if it is related or not.

Well it's been ok now since that last Aug15 disconnect... So maybe Bell did have several days during a span of a couple weeks of fixing stuff up in my area...

The Cellpipe itself has been up for nearly 1 month after the firmware upgrade.

Still havent heard about the compensation we were supposed to get after it was fixed...
