I recently bought a new Motorola SB5100 cable modem. So far I'm pleased
with it but have noticed something strange with the log page. It seems
the log grew until it was full and then instead of adding new entries and
deleting the oldest entries, it keeps writing over the most recent entry.
So the log is full of old stuff and it just keeps writing over the most
recent entry. Has anyone else noticed this? Thanks

Mine does this as well. In addition to that, Comcast doesn't offer time
stamps so the time recorded in the log is false.

That's interesting. I wonder if this is a problem with all SB5100's. I
also have Comcast. But the timestamps seem to be correct. When I first
powered it up, it showed the 1970-01-01 date. But then it seems to get the
correct time/date and seems to be close since then. What are you getting
for time and date?

Even more interesting is that today I did see the top 4 date/time lines
stamped with today's date and a time. I mentioned in another forum that
my SunRocket VOIP went out early this morning and at the same time my
Comcast was very sluggish and timed out frequently. I recycled both my
VOIP and 5100 boxes many times, but no indication of a time stamp during
that time. I do see some odd assorted date/times further on down.
Nothing consistent. I was told by Comcast/Motorola that the log has no
purpose for the user...only for the providers...I have never been asked
to supply the information or error codes. This is the legend at the top
of my log....

This page displays detailed information intended for use by an
authorized Motorola Cable Modem technician.

This is typically what I do get....

Well, my experience is that no one at Comcast wants to take the time to look
at the log. I had poor service (dropped connection) for some time (2
years). They scheduled a service call each time only to say everything was
fine. Finally I started checking things out myself. Both the upstream and
downstream levels were on the ragged edge and when temperatures varied it
would start dropping connection. I started calling and reporting the levels
as a problem. As it turned out, the customer service tech and the tech
dispatched didn't seem to have a clue. They couldn't even carry on a
conversation about the acceptable range for each level. And they damn sure
didn't look at the modem log or signal levels. I kept it up until they
found the problems including a bad transmitter in the node. My levels are
pretty good now (downstream=0, upstream=38 and snr=37). Now I'm
experiencing problems (intermittent snr) when there are high winds.
Apparently they have an aerial cable problem. But it'll take several
reports and a lot of complaining to get anything fixed.

Bottom line is Comcast could care less about the modem log. But it is a
good source of information for my complaints to them.
