OT? - Broadband Troubleshooting

[Greg]

Thank you all for the suggestions.

It would be difficult to bypass the entire house network, or at least 
there would be significant impact.  That said, I do intend to try to 
"shed load" and see if I can alter the problem.  The difficulty is that 
it's fairly intermittent.  Perhaps a dozen times a day I'll have 
difficulty painting a web page (I'm usually online all day long) and I 
have problems with 1 call in 10 and I only make 10 calls a day (so once 
a day).

My specific troubleshooting, in order, will be:

I'll try shedding load.

I'll go into the cable modem (not the router) and see if I can get logs 
or screen scrape and try to correlate problems with these logs.

Finally, depending on the above, I'll try logging ping/smokeping to 
various locations (Gateway/Router, DNS, some key (but close) Comcast 
router, a random website or two) and see if I can correlate a delay with 
something.

It will likely take a little while but if I find something specific I'll 
post the fix.

Thanks again.  GGK
