Has Linux got tools that can run while a computer runs that can poll

restored. This is a new wifi router too. The log would be sent into
comcast along with payment requesting credits for the down times.
I suggest:
1. Test and verify your network cables:

2. Buy and read "Networking for System Administrators" by Lucas:

3. Write a shell script that invokes some standard utility (ping(8),
wget(1), etc.), appends a timestamp and the utility output to a log
file, sleeps for 60 seconds, and then repeats. >
Along with redirecting the output to a file, the logger(1) utility can
also be used (1) to make entry in the system log.

Yes -- that would be a possible follow-on exercise to #3. Also see
rsyslog(8) and rsyslog.conf(5).
