678.  There is one newer FW rev to upgrade too (on my todo list).  I've had
this thing for years and started doing this in the past few weeks (seems
like its getting worse).  Since it goes in & out of slow response, I'm
thinking something is using the connection periodically.  I'm hoping to
learn how to find out how to determine that!  Your idea on age-failing is
interesting though...

Show errors reports nothing (the usual DHCP messages only).

"sh int eth0" had some errors for receive (rebooting reset to 0; will see if
it increases during the slow responses).

I'll check on its warmth (in the mechanical room with my servers on top of
switch; room temp is good) & try a different switch port.  

Thank you for the ideas!

What version of code are you running? Maybe a newer version could help.

Check "show errors" and also look at the eth interface stats for various
error counters on the cisco.

Additionally some models of the 67x (you didn't mention which you have) get
very hot on their own so if you have it in an already warm room with minimal
air flow it could be overheating and nearing the end of its life. If this
seems like the case then try propping it up so the bottom is more accessible
to some air flow. 
You could check the cable from the Cisco, try replacing it with another
cable. Is it going to a switch? Try another switch port. Basic things like
that can sometimes identify/eliminate during troubleshooting and are super
easy to try.

Lately I've had a lot of slowdown with my DSL router.  None of the machines
appear to be downloading, streaming, etc. (they could be, but didn't look
like it to me).  For example, at the moment, pinging the router:

PING dslrouter (10.0.0.1) 56(84) bytes of data.
64 bytes from dslrouter (10.0.0.1): icmp_seq=1 ttl=64 time=1686 ms

rtt min/avg/max/mdev = 762.641/1186.396/1686.273/312.092 ms, pipe 2


After I reboot it, it's back to sub-millisecond time.  But after a short
while, it's back up there.  It's really slowing down even casual surfing,
and the wife keeps yelling at me about it!  :-/


And then sometimes, like now, it is back to normal (but it was slow response
for awhile, maybe an hour or more?):

PING dslrouter (10.0.0.1) 56(84) bytes of data.
64 bytes from dslrouter (10.0.0.1): icmp_seq=1 ttl=64 time=0.811 ms

How do I detect what is happening at the time of high load?
It is a Cisco CBOS DSL router.  I've been trying some CBOS show commands and
wondering about either Linux or Windows commands/apps to use?
