As yet I have not been there when this happens, so cannot confirm ping
success or failure. They've learned to turn off the switch to the power strip
that supplies the routers and modem, and after a few seconds, all is well
with the world again.

Write a simple script that is also an icon on the desktop. When
router locks, then each user clicks on that icon to collect and store
relevant information in a temporary file.

Some of the tasks that script must perform include
ping 192.168.1.1 tmpfile
ping 192.168.1.100 tmpfile
ipconfig /all tmpfile

When you arrive, view what computers talk to router, what computers
talk to each other, and even what computers still have IP leases.
There is still no reason to believe power created this problem. If
so, then why is the router's power supply so deficient as to not
eliminate things that other power supplies (ie computers, modem, etc)
easily make irrelevant?

Like the temporary 50 foot power cord, meter measurement (numbers
then posted here so that other information you did not see in those
numbers can be identified), $10 line filter, etc. So many simple
things to first learn where a problem is rather than just
automatically assume (for no reason) that it must be 'dirty' power and
that a $500 UPS must cure it.

You don't even have to be there when router locks up. Voltages from
the meter could report defects even when router is working OK. Again,
we first collect data before automatically speculating blame. If
power is the problem, then why is only one appliance failing? A
question that PG&E will ask, be discouraged by an answer based only in
speculation, and then tend to be less cooperative. To get useful
assistance from PG&E, wild speculation (it must be a power problem)
with is not sufficient. Why do you suspect power? No post here
suggests that power is reason for the failure.

How do you know the problem is not expired IP leases? Again, not
posted to be a solution. Posted as but another example of the so many
existing reasons ignored because speculation blames AC electricity.
