For the past few weeks of testing and playing around with my new router. I have came up with a perfect solution for a dsl connection on AT&T & SBC Connections. Here is my current config running on the router:

set clock command:
example:
set clock 08:30:30 January 29 2011
Router#show clock detail

Time source is user configuration
how to delete crashinfo files:
delete flash:
or
delete flash:crashinfo *
Then hit enter key, not the "y" key as it will show error. Once you are done deleting all the crashinfo files. Do a squeeze command.
example:
type: "squeeze flash"
this command could take a few minutes to complete.
