Any name-brand UPS will have genuine surge protection. A power strip

Cite manufacuture specs that claim that protection. You cannot.
Entire protection circuit in a plug-in UPS is the same circuit inside
power strip protectors. But again, where do they list each type of
surge and numbers that define that protection? They do not which is
why you do not cite spec numbers.

More embarrassing, a UPS protector circuit is often grossly
undersized even compared to power strips. That too will be obvious
once those manufacturer spec numbers are provided. So where is this
superior protection?

Meanwhile, any problem that might be causing the OPs router lock up
would also be completely ignored by MOVs. Review numbers that are
even printed on the box. Is this post sharp? Yes. You made claims
that even manufacturer numbers do not say. Why make claims without
first learning the technology?

UPS is to protect data from blackouts and brownouts. Once saved to
disk, then data needs no such protection. How robust is protection
inside computers? So robust that some of the dirtiest electricity -
from a UPS in battery backup mode - still does not harm a computer.
What is a source of some 'dirtiest' electricity? Many who did not
first learn the numbers will automatically *assume* a UPS means
'cleaner' electricity. What is a source of dirtiest electricity? Did
you read those specs? That is what a good business manager does -
learn the facts before making a recommendation.

Meanwhile, MOVs (the protection circuit inside a plug-in UPS) will
do nothing for the OP's router problem.
