Scary are those who only want to cure symptoms.

In this particular situation, the building will be bulldozed in less than a
year. Building management is not about to have a major repair done on the
electric supply for the building in this time period.

So if, upon closer examination, it is determined that the problem is caused
by loads elsewhere in the building generating spikes, confounded by
inadequate wiring and/or imbalanced phases and overloaded neutrals, a $500
fix may indeed be our only choice.

Agree with the poster that pointed out that components such as routers should
be able to withstand larger power quality issues than they are currently
designed to withstand, if profit weren't the primary goal of the
manufacturer.
